Raffriff42: /* Color conversion and adjustment filters */ fix double-spaced ConvertToYUVA444 etc

<div style="max-width:76em; min-width:48em">
The available (internal) filters are listed here and divided into categories. A short description is added, including the supported [[Color_spaces|color formats]] (and sample types for the audio filters). There are some functions which combine two or more clips in different ways. How the video content is calculated is described for each function, but [[filters_with_multiple_input_clips|here is a summary which explains which properties that the resulting clip will have]].

An alphabetical listing of the internal filters can be found [[:Category:Internal_filters|here]].

=== Source filters ===

These filters can read media files and return an AviSynth clip. See [[#Debug_filters|debug filters]] for non-file source filters.

=== Interlace filters ===

These filters can be used for creating and processing field-based material (which is frame-based material separated into fields). AviSynth is capable of dealing with both progressive and interlaced material. The main problem is, that it often doesn't know what it receives from source filters. This is the reason that the field-based flag exists and can be used when dealing with interlaced material. More information about field-based video can be found [[Interlaced_fieldbased|here]].

=== Audio processing filters ===

These filters process audio. Audio samples will be automatically converted if any filters requires a special type of sample. This means that if a filter doesn't support the type of sample it is given, it will automatically convert the samples to something it supports. The internal formats supported in each filter is listed in the sample type column. A specific sample type can be forced by using the [[ConvertAudio]] functions.

{{AvsPluscon}} automatic conversion is ''not'' performed. The new behavior is to raise an error when a sample type is not compatible. It is your responsibility to use [[ConvertAudio]] where needed.

[[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true. In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.

{| style="height:100px; width:95%" border="1" cellpadding="4" class="wikitable"

=== Conditional and other meta filters ===

''Meta'' filters can be used to control other filters' execution. The basic characteristic of conditional filters is that their scripts are evaluated (executed) at every frame instead of when the clip is loaded. This allows for complex video processing that would be difficult or impossible to be performed by a normal AviSynth script.

Raffriff42: Float audio range notes

''This page is about the ''Float ''audio format.'' <br>
:''For the variable type, see [[Script_variables]].'' <br>
:''For the'' <code>Float()</code> ''function, go to [[Internal_functions#Float]].'' <br>
:''For the {{Deep_color}} format, go to [[Float_(color_format)]]''

'''Float''' (or fully IEEE floating point with single precision) is one of the [[ConvertAudio|AviSynth audio sample formats]].

The samples of this type have normal values between -1.0 (= 0xBF800000) and +1.0 (= 0x3F800000). Values outside this range are usable as long as the audio remains in Float format, but will create audio clipping if [[ConvertAudio|converted]] to an integer format: 8, 16, 24 or 32 integer bits. For safety, you can call [[Normalize]] before converting from Float to Integer.

ColorBarsHD ## audio format = Float; range -1.0 - +1.0
Amplify(1000.0) ## range -1000.0 - +1000.0
Amplify(0.001) ## range -1.0 - +1.0
## output: unchanged

ColorBarsHD ## audio format = Float; range -1.0 - +1.0
Amplify(1000.0) ## range -1000.0 - +1000.0
ConvertAudioTo16bit ## convert to Integer; severe clipping
Amplify(0.001) ## still clipping

The value of such a IEEE-754 number is computed as: sign * 2^exponent * 1.mantissa, using the following scheme:

<code>[ 1 Sign Bit | 8 Bit Exponent | 23 Bit Mantissa ]</code>

* The sign bit is 1 (negative) or 0 (positive).
* The exponent runs from -127 (00000000) to 0 (0111111) to 128 (11111111).
* The mantissa m1m2m3 ... means m1/2 + m2/4 + m3/8 + ... in decimal. Sometimes people denote "1.m1m2m3..." as the mantissa (like is done in the converter below).

For an on-line converter between decimal numbers and IEEE 754 floating point, see [http://www.h-schmidt.net/FloatConverter/IEEE754.html here].

Examples:

0x3F800000 = 00111111100000000000000000000000 (binary, see [http://easycalculation.com/hex-converter.php])

Sign Bit Exp 1.Mantissa
0 01111111 00000000000000000000000

127 - 127 = 0 1.0 bitshift 0 places

Sign bit is positive, exponent = 0, 1.mantissa = 1, so the number is +1.0

and

0xBF800000 = 10111111100000000000000000000000

Sign Bit Exp 1.Mantissa
1 01111111 00000000000000000000000

127 - 127 = 0 1.0 bitshift 0 places

Sign bit is negative, exponent = 0, 1.mantissa = 1, so the number is -1.0

and

0x800000 = 01001011000000000000000000000000

Sign Bit Exp 1.Mantissa
0 10010110 00000000000000000000000

150 - 127 = 23 1.0 bitshift 23 places

Sign bit is positive, exponent = 23, 1.mantissa = 1, so the number is 8388608

In addition to [[Internal_filters|internal filters]] AviSynth has a fairly large number of other (non-clip) internal functions.

The input or/and output of these functions are not clips, but some other variables which can be used in a script.

== Boolean functions ==
<div style="max-width:62em" >
: These return true or false, if the condition that they test holds or not, respectively.

{{ScriptFunctionH5|IsBool||IsBool(var)}}
: Tests if {{FuncArg|var}} is of the bool type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b = false
IsBool(b) = true
IsBool(1 < 2 && 0 == 1) = true
IsBool(123) = false
</div>

{{ScriptFunctionH5|IsClip||IsClip(var)}}
: Tests if {{FuncArg|var}} is of the clip type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >

c = [[AviSource]](...)
IsClip(c) = true
IsClip("c") = false
</div>

{{ScriptFunctionH5|IsFloat||IsFloat(var)}}
: Tests if {{FuncArg|var}} is of the float type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
f = [[Internal_functions/Numeric_functions|Sqrt]](2)
IsFloat(f) = true
IsFloat(true) = false
IsFloat("42.") = false
IsFloat(2) = true # ''ints are considered to be floats by this function''
IsReallyFloat(2) = false # see below
</div>
: As a workaround for the issue noted above, you may use the following [[User_functions|user function]]:
<div {{BoxWidthIndent|46|3}} >
## return true for floats only
function IsReallyFloat(val v)
{
return (IsInt(v)==false) && IsFloat(v)
}
</div>

{{ScriptFunctionH5|IsInt||IsInt(var)}}
: Tests if {{FuncArg|var}} is of the int type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsInt(2) = true
IsInt(2.1) = false
IsInt(true) = false
</div>

{{ScriptFunctionH5|IsString||IsString(var)}}
: Tests if {{FuncArg|var}} is of the string type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsString("test") = true
IsString(2.3) = false
IsString([[Internal_functions/Conversion_functions|String]](2.3)) = true
</div>

{{ScriptFunctionH5|Exist||Exist(filename)}}
: Tests if the file specified by {{FuncArg|filename}} exists.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
filename = ...
clp = Exist(filename)
\ ? [[AviSource]](filename)
\ : [[Internal_functions/Control_functions|Assert]](false, "file: " + filename + " does not exist")
</div>

{{ScriptFunctionH5|Defined||Defined(var)}}
: Tests if {{FuncArg|var}} is defined. Can be used inside [[Script_functions]] to test if an optional argument has been given an explicit value.
: More formally, the function returns false if its argument (normally a function argument or variable) has the void ('undefined') type, otherwise it returns true.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b_arg_supplied = Defined(arg)
myvar = b_arg_supplied ? ... : ...
</div>

{{ScriptFunctionH5|FunctionExists|{{AvsPluscon}}|FunctionExists(name)}}
: Tests if the function or filter name is defined in the script.
: {{FuncArg|name}} can be any string – it does not need to be a [[Script_variables#Variable_Names|legal name]].
: ''Example'' – see [[#Apply|Apply]] below

{{ScriptFunctionH5|InternalFunctionExists|{{AvsPluscon}}|InternalFunctionExists(name)}}
: Tests if the function, filter or [[Clip_properties|property]] name is defined natively within [[AviSynth+]].
:* Unlike [[#FunctionExists|FunctionExists]], returns ''false'' for [[Plugins|external plugins]] and [[User_functions|user-defined functions]].
</div>

{{ScriptFunctionH5|VarExist|{{AvsPluscon}}|VarExist(name)}}
: Tests if the variable exists or not. Note: if variable exists, it returns true regardless of the "defined" state of the variable
</div>

== Control functions ==
<div style="max-width:62em" >
: These facilitate flow of control (loading of scripts, arguments checks, global settings adjustment, etc.).

{{ScriptFunctionH5|Apply||Apply(string ''func_string'' [, arg1 [, arg2 [, ... [, arg''n'']]]] )}}
: Calls the function or filter {{FuncArg|func_string}} with arguments {{FuncArg|arg1}}, {{FuncArg|arg2}}, ..., {{FuncArg|arg''n''}} (as many as supplied).
:* This provides a way to call a function or filter '''by name''', with arguments.
:* <code>Apply("f", x)</code> is equivalent to <code>f(x)</code>
:* <code>Apply("f", x)</code> is equivalent to <code>[[#Eval|Eval]]("f(" + String(x) + ")")</code>
:* Note that the clip argument must be supplied explicitly - the [[Last|special variable ''Last'']] is not used.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
## Building an expression dynamically
new_width = 352
new_height = 288

Apply("[[BicubicResize]]", Last, new_width, new_height)
# Note that the clip argument must be supplied - 'Last' is not implicitly assumed

## the same action, using [[#Eval|Eval]]
Eval( "BicubicResize(" + String(new_width) + "," + String(new_height) + ")" )
</div>

<div {{BoxWidthIndent|56|2}} >
## using a filter only if it exists (AviSynth 2.6)
function MyFilter(clip C, string s) {
return C.[[Subtitle]]("MyFilter: "+s, align=5)

## using a filter only if it exists ([[AviSynth+|AVS+]] only)
ColorBars
return [[#FunctionExists|FunctionExists]]("MyFilter")
\ ? Apply("MyFilter", Last, "TEST")
\ : Last
</div>

{{ScriptFunctionH5|Eval||Eval(expression [, string ''name''])}}
: Evaluates an arbitrary {{FuncArg|expression}} and returns the result of that evaluation. '''It works exactly like [[#Import|Import]] below''', except
:* The expression to be evaluated comes from a string instead of a file;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are not changed;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is not changed.
: Argument {{FuncArg|name}} will be shown in the error message beside the script name. Both will be followed with the line number in {{FuncArg|expression}} where the error occurred.

: Variables in your calling script are available within {{FuncArg|expression}}; [[Global|global variables]] are not required.
: Note '''Eval''' can return the result of ''any'' valid expression; usually a clip, but also a string, boolean etc.
: You can use '''Eval''' to construct and evaluate expressions dynamically inside your scripts, based on variable input data.
: '''Eval''' is useful as a [[Control_structures|control structure]] for creating multi-line ''block statements'' without requiring [[AviSynth%2B|AviSynth+]].
: '''Eval''' can be used to put aside the need to install external plugins if they are not actually used.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
## Building an expression dynamically
## calls [[BicubicResize]](last, 352, 288)
settings = "352, 288"
Eval( "BicubicResize(" + settings + ")" )

(E:\_test.avs, line 6)
</div>

{{ScriptFunctionH5|Import||Import(filename)}}
{{ScriptFunctionCode|Import||Import(filename [, ...] [, bool utf8])}} {{AvsPluscon}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.
:* {{FuncArg|utf8}} {{AvsPluscon}} if true, assumes filename(s) are [[wikipedia:UTF-8|UTF8]], else (default), assume ANSI.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >
ColorBars
A=Subtitle("A", align=5) ## create clip 'A'
Import("B.avsi")
return Last ## returns clip 'A' with colors inverted
</div>

<div {{BoxWidthIndent|56|2}} >
## here we do not care about the return value (''mylib.avsi'' contains only functions)
Import("mylib.avsi")
...
## ''mysources.avsi'' loads predetermined file names from a folder into globals
okflag = Import("mysources.avsi")
source = okflag ? global1 + global2 + global3 : [[BlankClip]]()
</div>

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])
</div>

Note - all branches are evaluated:
<div {{BoxWidthIndent|56|2}} >
index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''
<div {{BoxWidthIndent|56|2}} >
preset = want_presets ? [[AviSource]]("c:\presets\any.avi") : NOP
...
loadlib ? [[Import]]("my_useful_functions.avs") : NOP
</div>

{{ScriptFunctionH5|Undefined|v2.60|Undefined()}}
: Returns the undefined state.
: It's the state for which '''Defined'''() returns false.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
x = Undefined()
Defined(x) # == false
</div>
</div>

== Global Options ==
<div style="max-width:62em" >
{{ScriptFunctionH5|SetMemoryMax||SetMemoryMax(amount)}}
: Sets the maximum memory that AviSynth uses (in MB) to the value of {{FuncArg|amount}}. Setting to zero just returns the current Memory Max value. In the 2.5 series the default Memory Max value is 25% of the free physical memory, with a minimum of 16MB.
: The default Memory Max is also limited to 512MB.

: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.
: Return value: Actual MemoryMax value set.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetMemoryMax(128)
</div>

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have
... # advanced memory alignment.
</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

{{ScriptFunctionH5|OPT_dwChannelMask|v2.60|global OPT_dwChannelMask(int v)}}
: This option enables you to set ChannelMask. It overrides WAVEFORMATEXTENSIBLE.dwChannelMask<sup>[[http://wiki.multimedia.cx/index.php?title=WAVEFORMATEXTENSIBLE]</sup> which is set according to this table

{{ScriptFunctionH5|OPT_AVIPadScanlines|v2.60|global OPT_AVIPadScanlines = true ## default false}}
: This option enables DWORD aligned planar padding. Default is packed aligned planar padding. See [[AVIFile output emulation|memory alignment used in the AVIFile output emulation]].<br>

{{ScriptFunctionH5|OPT_VDubPlanarHack|v2.60|global OPT_VDubPlanarHack = true ## default false}}
: This option enables flipped YV24 and YV16 chroma planes. This is an hack for early versions of Virtualdub with YV24/YV16 support. <br>

{{ScriptFunctionH5|OPT_Enable_V210|{{AvsPluscon}}|global OPT_Enable_V210 = true ## default false}}
: For 10bit YUV422, [[Frameserver|Frameserve]] interleaved V210 instead of planar P210. (VfW)
<div {{BoxWidthIndent|56|2}} >
{{BoldColor|black|100|§}} ''VfW'' here means [[wikipedia:Video_for_Windows|Video For Windows]] clients such as VirtualDub are affected, but not other clients such as ffmpeg.
</div>

{{ScriptFunctionH5|OPT_Enable_Y3_10_10|{{AvsPluscon}}|global OPT_Enable_Y3_10_10 = true ## default false}}
: For 10bit YUV422, set the [[FourCC]] to Y3[10][10] ('Y', '3', 10, 10) instead of P210 ('P', '2', '1', '0'). (VfW) <br>

== Boolean functions ==
<div style="max-width:62em" >
: These return true or false, if the condition that they test holds or not, respectively.

{{ScriptFunctionH5|IsBool||IsBool(var)}}
: Tests if {{FuncArg|var}} is of the bool type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''

IsFloat(true) = false
IsFloat("42.") = false
IsFloat(2) = true # ''ints are considered to be floats by this function''

## return true for floats only
function IsReallyFloat(val v)
{
return (IsInt(v)==false) && IsFloat(v)
}
</div>

{{ScriptFunctionH5|IsInt||IsInt(var)}}
: Tests if {{FuncArg|var}} is of the int type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsInt(2) = true
IsInt(2.1) = false
IsInt(true) = false

\ : [[Internal_functions/Control_functions|Assert]](false, "file: " + filename + " does not exist")
</div>

{{ScriptFunctionH5|Defined||Defined(var)}}
: Tests if {{FuncArg|var}} is defined. Can be used inside [[Script_functions]] to test if an optional argument has been given an explicit value.
: More formally, the function returns false if its argument (normally a function argument or variable) has the void ('undefined') type, otherwise it returns true.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b_arg_supplied = Defined(arg)
myvar = b_arg_supplied ? ... : ...
</div>

{{ScriptFunctionH5|FunctionExists|{{AvsPluscon}}|FunctionExists(name)}}
: Tests if the function or filter name is defined in the script.
: {{FuncArg|name}} can be any string – it does not need to be a [[Script_variables#Variable_Names|legal name]].
: ''Example'' – see [[#Apply|Apply]] below

{{ScriptFunctionH5|InternalFunctionExists|{{AvsPluscon}}|InternalFunctionExists(name)}}
: Tests if the function, filter or [[Clip_properties|property]] name is defined natively within [[AviSynth+]].
:* Unlike [[#FunctionExists|FunctionExists]], returns ''false'' for [[Plugins|external plugins]] and [[User_functions|user-defined functions]].
</div>

{{ScriptFunctionH5|VarExist|{{AvsPluscon}}|VarExist(name)}}
: Tests if the variable exists or not. Note: if variable exists, it returns true regardless of the "defined" state of the variable
</div>

== Control functions ==
<div style="max-width:62em" >
: These facilitate flow of control (loading of scripts, arguments checks, global settings adjustment, etc.).

{{ScriptFunctionH5|Apply||Apply(string ''func_string'' [, arg1 [, arg2 [, ... [, arg''n'']]]] )}}
: Calls the function or filter {{FuncArg|func_string}} with arguments {{FuncArg|arg1}}, {{FuncArg|arg2}}, ..., {{FuncArg|arg''n''}} (as many as supplied).
:* This provides a way to call a function or filter '''by name''', with arguments.
:* <code>Apply("f", x)</code> is equivalent to <code>f(x)</code>
:* <code>Apply("f", x)</code> is equivalent to <code>[[#Eval|Eval]]("f(" + String(x) + ")")</code>
:* Note that the clip argument must be supplied explicitly - the [[Last|special variable ''Last'']] is not used.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
## Building an expression dynamically
new_width = 352
new_height = 288

{{ScriptFunctionH5|Eval||Eval(expression [, string ''name''])}}
: Evaluates an arbitrary {{FuncArg|expression}} and returns the result of that evaluation. '''It works exactly like [[#Import|Import]] below''', except
:* The expression to be evaluated comes from a string instead of a file;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are not changed;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is not changed.
: Argument {{FuncArg|name}} will be shown in the error message beside the script name. Both will be followed with the line number in {{FuncArg|expression}} where the error occurred.

: Variables in your calling script are available within {{FuncArg|expression}}; [[Global|global variables]] are not required.
: Note '''Eval''' can return the result of ''any'' valid expression; usually a clip, but also a string, boolean etc.
: You can use '''Eval''' to construct and evaluate expressions dynamically inside your scripts, based on variable input data.
: '''Eval''' is useful as a [[Control_structures|control structure]] for creating multi-line ''block statements'' without requiring [[AviSynth%2B|AviSynth+]].
: '''Eval''' can be used to put aside the need to install external plugins if they are not actually used.
''Examples:''
<div {{BoxWidthIndent|56|2}} >

{{ScriptFunctionH5|Import||Import(filename)}}
{{ScriptFunctionCode|Import||Import(filename [, ...] [, bool utf8])}} {{AvsPluscon}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.
:* {{FuncArg|utf8}} {{AvsPluscon}} if true, assumes filename(s) are [[wikipedia:UTF-8|UTF8]], else (default), assume ANSI.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >
ColorBars
A=Subtitle("A", align=5) ## create clip 'A'
Import("B.avsi")
return Last ## returns clip 'A' with colors inverted
</div>

<div {{BoxWidthIndent|56|2}} >
## here we do not care about the return value (''mylib.avsi'' contains only functions)
Import("mylib.avsi")
...
## ''mysources.avsi'' loads predetermined file names from a folder into globals
okflag = Import("mysources.avsi")
source = okflag ? global1 + global2 + global3 : [[BlankClip]]()
</div>

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])
</div>

Note - all branches are evaluated:
<div {{BoxWidthIndent|56|2}} >
index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''
<div {{BoxWidthIndent|56|2}} >
preset = want_presets ? [[AviSource]]("c:\presets\any.avi") : NOP
...
loadlib ? [[Import]]("my_useful_functions.avs") : NOP
</div>

{{ScriptFunctionH5|Undefined|v2.60|Undefined()}}
: Returns the undefined state.

x = Undefined()
Defined(x) # == false
</div>
</div>

{{ScriptFunctionH5|SetMemoryMax||SetMemoryMax(amount)}}
: Sets the maximum memory that AviSynth uses (in MB) to the value of {{FuncArg|amount}}. Setting to zero just returns the current Memory Max value. In the 2.5 series the default Memory Max value is 25% of the free physical memory, with a minimum of 16MB.

: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.
: Return value: Actual MemoryMax value set.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetMemoryMax(128)
</div>

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have
... # advanced memory alignment.
</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

{{ScriptFunctionH5|OPT_dwChannelMask|v2.60|global OPT_dwChannelMask(int v)}}

== Boolean functions ==
<div style="max-width:62em" >
: These return true or false, if the condition that they test holds or not, respectively.

{{ScriptFunctionH5|IsBool||IsBool(var)}}
: Tests if {{FuncArg|var}} is of the bool type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].

IsFloat(true) = false
IsFloat("42.") = false
IsFloat(2) = true # ''ints are considered to be floats by this function''

## return true for floats only
function IsReallyFloat(val v)
{
return (IsInt(v)==false) && IsFloat(v)
}
</div>

{{ScriptFunctionH5|IsInt||IsInt(var)}}
: Tests if {{FuncArg|var}} is of the int type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsInt(2) = true
IsInt(2.1) = false
IsInt(true) = false

\ : [[Internal_functions/Control_functions|Assert]](false, "file: " + filename + " does not exist")
</div>

{{ScriptFunctionH5|Defined||Defined(var)}}
: Tests if {{FuncArg|var}} is defined. Can be used inside [[Script_functions]] to test if an optional argument has been given an explicit value.
: More formally, the function returns false if its argument (normally a function argument or variable) has the void ('undefined') type, otherwise it returns true.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b_arg_supplied = Defined(arg)
myvar = b_arg_supplied ? ... : ...
</div>

{{ScriptFunctionH5|FunctionExists|{{AvsPluscon}}|FunctionExists(name)}}
: Tests if the function or filter name is defined in the script.
: {{FuncArg|name}} can be any string – it does not need to be a [[Script_variables#Variable_Names|legal name]].
: ''Example'' – see [[#Apply|Apply]] below

{{ScriptFunctionH5|InternalFunctionExists|{{AvsPluscon}}|InternalFunctionExists(name)}}
: Tests if the function, filter or [[Clip_properties|property]] name is defined natively within [[AviSynth+]].
:* Unlike [[#FunctionExists|FunctionExists]], returns ''false'' for [[Plugins|external plugins]] and [[User_functions|user-defined functions]].
</div>

{{ScriptFunctionH5|VarExists|{{AvsPluscon}}|VarExists(name)}}
: Tests if the variable exists or not. Note: if variable exists, it returns true regardless of the "defined" state of the variable
</div>

== Control functions ==
<div style="max-width:62em" >
: These facilitate flow of control (loading of scripts, arguments checks, global settings adjustment, etc.).

{{ScriptFunctionH5|Apply||Apply(string ''func_string'' [, arg1 [, arg2 [, ... [, arg''n'']]]] )}}
: Calls the function or filter {{FuncArg|func_string}} with arguments {{FuncArg|arg1}}, {{FuncArg|arg2}}, ..., {{FuncArg|arg''n''}} (as many as supplied).
:* This provides a way to call a function or filter '''by name''', with arguments.
:* <code>Apply("f", x)</code> is equivalent to <code>f(x)</code>
:* <code>Apply("f", x)</code> is equivalent to <code>[[#Eval|Eval]]("f(" + String(x) + ")")</code>
:* Note that the clip argument must be supplied explicitly - the [[Last|special variable ''Last'']] is not used.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
## Building an expression dynamically
new_width = 352
new_height = 288

{{ScriptFunctionH5|Eval||Eval(expression [, string ''name''])}}
: Evaluates an arbitrary {{FuncArg|expression}} and returns the result of that evaluation. '''It works exactly like [[#Import|Import]] below''', except
:* The expression to be evaluated comes from a string instead of a file;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are not changed;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is not changed.
: Argument {{FuncArg|name}} will be shown in the error message beside the script name. Both will be followed with the line number in {{FuncArg|expression}} where the error occurred.

: Variables in your calling script are available within {{FuncArg|expression}}; [[Global|global variables]] are not required.
: Note '''Eval''' can return the result of ''any'' valid expression; usually a clip, but also a string, boolean etc.
: You can use '''Eval''' to construct and evaluate expressions dynamically inside your scripts, based on variable input data.
: '''Eval''' is useful as a [[Control_structures|control structure]] for creating multi-line ''block statements'' without requiring [[AviSynth%2B|AviSynth+]].
: '''Eval''' can be used to put aside the need to install external plugins if they are not actually used.
''Examples:''

{{ScriptFunctionH5|Import||Import(filename)}}
{{ScriptFunctionCode|Import||Import(filename [, ...] [, bool utf8])}} {{AvsPluscon}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.
:* {{FuncArg|utf8}} {{AvsPluscon}} if true, assumes filename(s) are [[wikipedia:UTF-8|UTF8]], else (default), assume ANSI.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >
ColorBars
A=Subtitle("A", align=5) ## create clip 'A'

return Last ## returns clip 'A' with colors inverted
</div>

<div {{BoxWidthIndent|56|2}} >
## here we do not care about the return value (''mylib.avsi'' contains only functions)
Import("mylib.avsi")

source = okflag ? global1 + global2 + global3 : [[BlankClip]]()
</div>

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])
</div>

Note - all branches are evaluated:
<div {{BoxWidthIndent|56|2}} >
index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''
<div {{BoxWidthIndent|56|2}} >

{{ScriptFunctionH5|SetMemoryMax||SetMemoryMax(amount)}}
: Sets the maximum memory that AviSynth uses (in MB) to the value of {{FuncArg|amount}}. Setting to zero just returns the current Memory Max value. In the 2.5 series the default Memory Max value is 25% of the free physical memory, with a minimum of 16MB.

: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.
: Return value: Actual MemoryMax value set.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetMemoryMax(128)
</div>

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have
... # advanced memory alignment.
</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

Raffriff42: typo

<div style="max-width:62em" >
Adjusts brightness, contrast, and gamma. This is done using the following ''transfer function'':
:''output'' = ( (''input'' - {{FuncArg|input_low}}) / ({{FuncArg|input_high}} - {{FuncArg|input_low}}) )<sup>(1 / {{FuncArg|gamma}})</sup> * ({{FuncArg|output_high}} - {{FuncArg|output_low}}) + {{FuncArg|output_low}}

*{{FuncArg|input_low}} and {{FuncArg|input_high}} determine what ''input'' pixel values are treated as pure black and pure white.
*{{FuncArg|output_low}} and {{FuncArg|output_high}} determine what ''output'' values are treated as pure black and pure white.
*{{FuncArg|gamma}} controls the degree of non-linearity in the conversion.

This is one of those filters for which it would really be nice to have a GUI. Since we can't offer a GUI (though [http://forum.doom9.org/showthread.php?t=153248 AvsP] does), we at least make this filter '''compatible''' with [[VirtualDub|VirtualDub's]] when the clip is [[RGB]]. In that case you should be able to take the numbers from VirtualDub's ''Levels'' dialog and pass them as parameters to the '''Levels''' filter and get the same results. Unlike VirtualDub's filter however, the input and output parameters can be larger than 255{{D}}.

When processing data in [[YUV]] mode, '''Levels''' only gamma-corrects the luma information, not the chroma. Gamma correction is really an RGB concept, and is only approximated here in YUV. If ''{{FuncArg|gamma}}=1.0'' (unity), the filter should have the same effect in both RGB and YUV modes. For adjusting brightness or contrast in YUV mode, it ''may'' be better (depending on the effect you are looking for) to use [[Tweak]] or [[ColorYUV]], because '''Levels''' changes the chroma of the clip.

Note in {{AvsPluscon}}, the parameters {{FuncArg|input_low}}, {{FuncArg|input_high}}, {{FuncArg|output_low}} and {{FuncArg|output_high}}
* are <tt>float</tt> instead of <tt>int</tt>.
* are not [[Autoscale_parameter|autoscaling]] – they are relative to the current bit depth:

==== Syntax and Parameters ====
{{FuncDef|Levels(clip ''input'', <br>
      int ''input_low'', float ''gamma'', int ''input_high'', int ''output_low'', int ''output_high''<br>
      [, bool ''coring'' , bool ''dither'' ] )}}<br>
{{FuncDef|Levels(clip ''input'', <br>
      float ''input_low'', float ''gamma'', float ''input_high'', float ''output_low'', float ''output_high''<br>
      [, bool ''coring'' , bool ''dither'' ] )}} {{AvsPluscon}}

:{{Par2|clip|clip|(required)}}
::Source video.

:{{Par2|input_low|int/float*|(required)}}
::Input values at {{FuncArg|input_low}} or lower are treated as ''black'', and lighter colors are darkened proportionally.
::Therefore raising {{FuncArg|input_low}} darkens the output.
:: <big>*</big> = <tt>int</tt> in AviSynth, <tt>float</tt> in AviSynth+

:{{Par2|gamma|float|(required)}}
::[[Wikipedia:Gamma_correction|Gamma]] adjustment. See [[#Examples|examples]].
::Higher {{FuncArg|gamma}} brightens the output; lower {{FuncArg|gamma}} darkens the output.

:{{Par2|input_high|int/float|(required)}}
::Input values at {{FuncArg|input_high}} or higher are treated as ''white'', and darker colors are brightened proportionally.
::Therefore lowering {{FuncArg|input_high}} brightens the output.

:{{Par2|output_low|int/float|(required)}}
::Dark values brighten to gray as {{FuncArg|output_low}} becomes larger.

:{{Par2|output_high|int/float|(required)}}
::Light values darken to gray as {{FuncArg|output_high}} becomes smaller.

:{{Par2|coring|bool|true}}
::When ''true'' (the default),
::#input luma is ''clamped'' to the range 16{{D}}-235{{D}} and the chroma to 16{{D}}-240{{D}};
::#this clamped input is ''scaled'' from 16{{D}}-235{{D}} to 0{{D}}-255{{D}},
::#the conversion takes place according to the transfer function above, and then
::#output is scaled back to 16{{D}}-235{{D}}.
::When ''false'', the conversion takes place according to the transfer function, without any scaling.

::{{FuncArg|coring}} was created for VirtualDub compatibility, and it remains true by default for compatibility with older scripts.
::In the opinion of some, you should [http://forum.doom9.org/showthread.php?p=1722885#post1722885 always use ''coring=false''] if you are working directly with luma values (whether or not your input is 16{{D}}-235{{D}}).

::'''Note''' TV-range video ''can'' be correctly processed with {{FuncArg|coring}}=false; for example,
:::<code>Levels({{BoldColor|blue|104|0}}, 1.6, {{BoldColor|blue|104|255}}, {{BoldColor|blue|104|0}}, {{BoldColor|blue|104|255}}, coring=true)</code>  
::produces the same result as
:::<code>Levels({{BoldColor|blue|104|16}}, 1.6, {{BoldColor|blue|104|235}}, {{BoldColor|blue|104|16}}, {{BoldColor|blue|104|235}}, coring=false)</code>
::except that the output is not clipped to TV-range. Black and white levels are preserved while adjusting {{FuncArg|gamma}}, unlike
:::<code>Levels(0, 1.6, 255, 0, 255, coring=false)</code>  

:{{Par2|dither|bool|false}}
::When ''true'', [[ordered dithering]] is applied to combat [http://en.wikipedia.org/wiki/Colour_banding banding]. Default is ''false''.

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====
A large list of filters can be downloaded from the following sites but be aware that some plugins listed '''may be outdated''', only recommended as a backup.

====Outdated AviSynth plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

| ColorMatrix
| ColorMatrix corrects the colors of MPEG-2 streams. More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

When the target format is the same as the source format, the original clip will be returned unchanged, except for the case of '''ConvertToYV12''' where the {{FuncArg|ChromaInPlacement}} and {{FuncArg|ChromaOutPlacement}} parameters are different.

{{BlueBox}}
There is no unique way of [[Color_conversions|converting]] YUV to RGB or vice-versa. There are different ''conversion matrices'' in use; the two most common ones are available in AviSynth, namely ''Rec.601'' and ''Rec.709'', plus some others. The following should be correct in ''most'' cases (see [[Colorimetry#How_can_I_see_if_the_correct_standard_is_used_upon_playback.3F|'''here''']] for more)
*Rec.601 should be used when your source is standard definition (usually defined as smaller than [[Wikipedia:720p|720p]]):
:<code>ConvertToRGB(clip)</code> (using default "Rec601")
*Rec.709 should be used when your source is DVD or HDTV:
:<code>ConvertToRGB(clip, matrix="Rec709")</code>
*The special-purpose matrices ''PC.601'' and ''PC.709'' keep the ''range'' unchanged,
:instead of converting between 0{{D}}-255{{D}} RGB and 16{{D}}-235{{D}} YUV, as is the normal practice.
*The special-purpose matrix ''AVERAGE'' is used for (rarely found) sources with ''unweighted'' luma,
:where ''Y'' = (R + G + B) / 3.
{{End_BlueBox}}

Note '''ConvertToRGB''' always converts to [[RGB32]] – unless your source is RGB24, in which case no conversion is done. If you need 24-bit RGB for some reason, use '''ConvertToRGB24''' explicitly.

Use '''ConvertBackToYUY2''' to convert ''back'' to YUY2 with minimal color-blurring when you have previously applied a YUY2→RGB conversion.

==== Parameter Details ====
{{HiddenH5|Matrix}}
{{Par2|matrix|string|"Rec601"}}
:Controls the colour coefficients and scaling factors used in RGB↔YUV conversions.
:*"Rec601"  : Uses Rec.601 coefficients; scale full range [0{{D}}..255{{D}}] RGB ↔ TV range [16{{D}}..235{{D}}] YUV.
:*"Rec709"  : Uses Rec.709 (HD) coefficients; scale full range RGB ↔ TV range YUV.
:*"Rec2020" : Uses Rec.2020 (UHD) coefficients; scale full range RGB ↔ TV range YUV. {{AvsPluscon}}
:*"PC.601"  : Uses Rec.601 coefficients; keep range unchanged.
:*"PC.709"  : Uses Rec.709 (HD) coefficients; keep range unchanged.
:*"Average"  : Uses averaged coefficients (the luma becomes the average of the RGB channels); keep range unchanged.

{{HiddenH5|Interlaced}}
{{Par2|interlaced|bool|false}}
:If true, it is assumed that {{FuncArg|clip}} is interlaced; by default, it is assumed to be progressive.
:This option is needed because for example, the following (assuming clip is interlaced YV12):
<div {{BoxWidthIndent|28|2}} >
[[SeparateFields]](clip)
ConvertToYUY2
[[Weave]]
</div>
:...is upsampled incorrectly. Instead it is better to use:
<div {{BoxWidthIndent|28|2}} >
ConvertToYUY2(clip, interlaced=true)
</div>
:Note, {{FuncArg|interlaced}}=true has an effect only on YV12↔YUY2 or YV12↔RGB conversions. More about that can be found [[Interlaced fieldbased|'''here''']].

{{HiddenH5|Chroma placement}}
{{Par2|ChromaInPlacement|string|"MPEG2"}}
{{Par2|ChromaOutPlacement|string|"MPEG2"}}
:{{FuncArg|ChromaInPlacement}} determines the chroma placement in the clip when converting ''from'' YV12.
:{{FuncArg|ChromaOutPlacement}} determines the chroma placement in the clip when converting ''to'' YV12.
:The placement can be one of these strings:
:{|class="wikitable" width="600"
|-
|"MPEG2" 
|Subsampling used in MPEG-2 4:2:''x'' and most other formats. Chroma samples are located on the left pixel column of the group (default).
|-
|"MPEG1"
|Subsampling used in MPEG-1 4:2:0. Chroma samples are located on the center of each group of 4 pixels.
|-
|"DV"
| Like MPEG-2, but U and V channels are “co-sited” vertically: V on the top row, and U on the bottom row. For 4:1:1, chroma is located on the leftmost column.
|}

{{HiddenH5|Chroma resample}}
{{Par2|chromaresample|string|"bicubic"}}
:Determines which chroma resampler is used in the conversion. Only used when the chroma resolutions of the source and target are different. All AviSynth [[Resize|resizers]] are allowed ("point", "bilinear", "bicubic", "lanczos", "lanczos4", "blackman", "spline16", "spline36", "spline64", "gauss" and "sinc"). Default is "bicubic".

===== Conversion paths =====

:In v2.60 the following conversion paths occur:
:* YUV planar → RGB via YV24
:* YUV planar → YUY2 via YV16
::(except for YV12 and chroma options listed above not explicitly set; in that case there is a direct conversion from YV12 to YUY2)
:* RGB → YUV planar via YV24
:* YUY2 → YUV planar via YV16
::(except for YV12 and chroma options listed above not explicitly set; in that case there is a direct conversion from YUY2 to YV12)

: The chroma options {{FuncArg|chromaresample}}, {{FuncArg|ChromaInPlacement}} and {{FuncArg|ChromaOutPlacement}} are only used in the 'planar conversion' part of the conversion path.

:Suppose you have a YUY2 clip for example and you convert it to YV24. The YUY2 will be converted to YV16 first without applying the chroma options. Then YV16 will be converted to YV24 while applying {{FuncArg|chromaresample}}. Since YV12 is not involved, {{FuncArg|ChromaInPlacement}} and {{FuncArg|ChromaOutPlacement}} won't be used.

<div style="max-width:62em" >
'''ColorYUV''' has many different methods of changing the color and luminance of your images. Gain, offset, gamma and contrast can be set independently on each channel. Also included are two 'auto' modes, an analysis function and a color gamut generator.

All settings for this filter are optional. All values are defaulting to "0" or false.

[[RGBAdjust]] works in a similar manner for [[RGB]] clips.

* In AviSynth 2.6, all [[YUV]] color formats are supported ([[Y8]], [[YV12]], [[YV16]], [[YV24]], [[YV411]] and [[YUY2]])
* {{AvsPluscon}} all [[YUV]] and [[YUVA]] color formats are supported, including [[Float_(color_format)|Float]].
* {{AvsPluscon}} all relevant parameters are [[Autoscale_parameter|autoscaling]] – they work without changes at all bit depths.

At the right side of the image, U is at maximum. At the bottom of the screen V is at its maximum. In the middle both chroma is 128{{D}} (or grey). See example image [[#Examples:|below]].
::{{AvsPluscon}} Size changes depending on options selected – see {{FuncArg|showyuv_fullrange}} below
::If {{FuncArg|bits}}=8, output colorspace is [[YV12]], else colorspace is [[Avisynthplus_color_formats|YUV422P16]].

:{{Par2|analyze|bool|false}}
::If true, '''ColorYUV''' will print color channel statistics on the screen (see [[#analyze|example below]])
::*There is an '''Average''' for all channels.
::*There are '''Minimum''' and '''Maximum''' values for all channels.
::*There is '''Loose Minimum''' and '''Loose Maximum''' which ignore the brightest and darkest 0.4% (1/256) pixels.

:{{Par2|autowhite|bool|false}}
::If ''true, ''this option will use the information from the analyzer, and attempt to center the color offsets. If you have recorded some material, where the colors are shifted toward one color, this filter may help. But be careful - it isn't very intelligent - if your material is a clear blue sky, {{FuncArg|autowhite}} will make it completely grey! This option overrides {{FuncArg|off_u|}} and {{FuncArg|off_v}}.

:{{Par2|autogain|bool|false}}
::If ''true, ''this option will use the information from the analyzer, and attempt to create as good contrast as possible. That means, it will scale up the ''Y ''(luma) values to match the minimum and maximum values. This will make it act like an "autogain" setting on cameras, amplifying dark scenes very much, while leaving scenes with good contrast alone. Some places this is also referred to as "autolevels".

:{{Par2|conditional|bool|false}}
::See the [[#Conditional_Variables|Conditional Variables]] section for an overview of the conditional variables and their use with '''ColorYUV'''. If ''false'' (the default), '''ColorYUV''' will ignore any conditional variables.

:{{Par2|bits|int|8}}
::{{AvsPluscon}} Sets the bit depth of {{FuncArg|showyuv}} output. Must be 8, 10, 12, 14 or 16.
::Size changes depending on options selected – see next item.

:{{Par2|showyuv_fullrange|bool|false}}
::{{AvsPluscon}} If ''true,'' {{FuncArg|showyuv}} output is full range instead of TV range.
::At {{FuncArg|bits}}=8, size of the generated clip grows from 450x450 to 512x512.
::At {{FuncArg|bits}}>8, size of the generated clip grows from 1800x1800 to 2048x2048.

:{{Par2|f2c|bool|false}}
::{{AvsPluscon}} If ''true,'' perform [[#Parameter Rescaling|''parameter rescaling'']] as described below on all '''cont_'''''x'', '''gain_'''''x'' and '''gamma_'''''x'' arguments.
::For example, with {{FuncArg|f2c}}=''true'', {{FuncArg|cont_u}}=1.2 results in a 20% increase in ''U'' channel "saturation".
</div>

==Parameter Rescaling==
<div style="max-width:62em" >
The quantities ''saturation'', ''contrast'' and ''brightness'' (as in [[Tweak]] for example) are connected with quantities in this filter by the following equations:
* {{FuncArg|cont_u}} = {{FuncArg|cont_v}} = ({{BoldColor|darkblue|100|sat}}-1) * 256
* {{FuncArg|gain_y}} = ({{BoldColor|darkblue|100|cont}}-1) * 256
* {{FuncArg|off_y}} = {{BoldColor|darkblue|100|bright}}
A saturation of 0.8 gives for example: cont_u = cont_v = -0.2 * 256 = -51.2.

Note that in [[Tweak]] your YUV values will always be clipped to valid TV-ranges, but here you have to specify {{FuncArg|opt}}="coring".

You can add a simple [[User_defined_script_functions|user function]] to rescale or translate from familiar "Tweak-like" units to ColorYUV units:
<div {{BoxWidthIndent|60|2}} >
function f2c(float f) {
return (f - 1.0) * 256.0
}

## usage example:
ColorYUV(gain_y=f2c({{BoldColor|blue|100|2.0}}), cont_u=f2c({{BoldColor|blue|100|1.2}}), cont_v=f2c({{BoldColor|blue|100|0.8}}))

## that is, gain is 200%, and contrast (saturation)
## is +20% in the U channel, -20% in the V channel.

## ...which specified normally, would look like this:
ColorYUV(gain_y={{BoldColor|blue|100|256}}, cont_u={{BoldColor|blue|100|51.2}}, cont_v={{BoldColor|blue|100|-51.2}})

## AVS+ users can rescale these arguments with the '''f2c''' option.
ColorYUV(gain_y={{BoldColor|blue|100|2.0}}, cont_u={{BoldColor|blue|100|1.2}}, cont_v={{BoldColor|blue|100|0.8}}, {{FuncArg|f2c}}=true)

</div>
</div>

== Conditional Variables ==
<div style="max-width:62em" >
The global variables "coloryuv_xxx" with xxx = gain_y, gain_u, gain_v, bright_y, bright_u, bright_v, gamma_y, contrast_y, contrast_u or contrast_v are read each frame, and applied. It is possible to modify these variables using [[FrameEvaluate]] or [[ConditionalReader]].

For example:

coloryuvoffset.txt:
<div {{BoxWidthIndent|56|2}} >
Type float
Default 0.0

I 25 50 0.0 255.0
R 75 225 128.0
I 250 275 255.0 0.0
</div>

the script:
<div {{BoxWidthIndent|56|2}} >
Colorbars(512,256).ConvertToYV12.Trim(0,299)
ColorYUV(cont_y=10, conditional=true)
ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false)
ShowFrameNumber()
</div>

So up to frame 25 gain_y is equal to the default (which is 0.0), for frame 25 up to 50 the gain_y is increased from 0.0 to 255.0, etc ...

There are more examples of conditional modification at the [[ConditionalReader]] page.
</div>

== Examples ==
<div style="max-width:62em" >
* Adjust ''Y ''(luma) gamma and offset (brightness), while increasing chroma ''U ''(yellow-blue) offset (away from yellow and toward blue)
<div {{BoxWidthIndent|56|2}} >

* {{FuncArg|autogain}} and {{FuncArg|autowhite}}: recovers visibility on "very bad" recordings:
<div {{BoxWidthIndent|56|2}} >
ColorYUV(autogain=true, autowhite=true)
</div>

* {{FuncArg|showyuv}}: show all colors in the [[YUV]] space. Requires a YUV clip as input.
:Returns a [[YV12]], 448x448 clip with source frame rate, duration and audio.

At the right side of the image, U is at maximum. At the bottom of the screen V is at its maximum. In the middle both chroma is 128{{D}} (or grey). See example image [[#Examples:|below]].
::{{AvsPluscon}} Size changes depending on options selected – see {{FuncArg|showyuv_fullrange}} below

::*There is an '''Average''' for all channels.

:{{Par2|autowhite|bool|false}}
::If ''true, ''this option will use the information from the analyzer, and attempt to center the color offsets. If you have recorded some material, where the colors are shifted toward one color, this filter may help.

:{{Par2|autogain|bool|false}}
::If ''true, ''this option will use the information from the analyzer, and attempt to create as good contrast as possible. That means, it will scale up the ''Y ''(luma) values to match the minimum and maximum values. This will make it act like an "autogain" setting on cameras, amplifying dark scenes very much, while leaving scenes with good contrast alone. Some places this is also referred to as "autolevels".

::See the [[#Conditional_Variables|Conditional Variables]] section for an overview of the conditional variables and their use with '''ColorYUV'''. If ''false'' (the default), '''ColorYUV''' will ignore any conditional variables.

:{{Par2|bits|int|8}}
::{{AvsPluscon}} Sets the bit depth of {{FuncArg|showyuv}} output. Must be 8, 10, 12, 14 or 16.
::Size changes depending on options selected – see next item.

:{{Par2|showyuv_fullrange|bool|false}}
::{{AvsPluscon}} If ''true,'' {{FuncArg|showyuv}} output is full range instead of TV range.
::At {{FuncArg|bits}}=8, size of the generated clip grows from 450x450 to 512x512.
::At {{FuncArg|bits}}>8, size of the generated clip grows from 1800x1800 to 2048x2048.

:{{Par2|f2c|bool|false}}
::{{AvsPluscon}} If ''true,'' perform [[#Parameter Rescaling|''parameter rescaling'']] as described below on all '''cont_'''''x'', '''gain_'''''x'' and '''gamma_'''''x'' arguments.
::For example, with {{FuncArg|f2c}}=''true'', {{FuncArg|cont_u}}=1.2 results in a 20% increase in ''U'' channel "saturation".
</div>

==Parameter Rescaling==
<div style="max-width:62em" >
The quantities ''saturation'', ''contrast'' and ''brightness'' (as in [[Tweak]] for example) are connected with quantities in this filter by the following equations:
* {{FuncArg|cont_u}} = {{FuncArg|cont_v}} = ({{BoldColor|darkblue|100|sat}}-1) * 256
* {{FuncArg|gain_y}} = ({{BoldColor|darkblue|100|cont}}-1) * 256
* {{FuncArg|off_y}} = {{BoldColor|darkblue|100|bright}}
A saturation of 0.8 gives for example: cont_u = cont_v = -0.2 * 256 = -51.2.

Note that in [[Tweak]] your YUV values will always be clipped to valid TV-ranges, but here you have to specify {{FuncArg|opt}}="coring".

You can add a simple [[User_defined_script_functions|user function]] to rescale or translate from familiar "Tweak-like" units to ColorYUV units:
<div {{BoxWidthIndent|60|2}} >
function f2c(float f) {
return (f - 1.0) * 256.0
}

## usage example:
ColorYUV(gain_y=f2c({{BoldColor|blue|100|2.0}}), cont_u=f2c({{BoldColor|blue|100|1.2}}), cont_v=f2c({{BoldColor|blue|100|0.8}})

## that is, gain is 200%, and contrast (saturation)
## is +20% in the U channel, -20% in the V channel.

## ...which specified normally, would look like this:
ColorYUV(gain_y={{BoldColor|blue|100|256}}, cont_u={{BoldColor|blue|100|51.2}}, cont_v={{BoldColor|blue|100|-51.2}})_

## AVS+ users can rescale these arguments with the '''f2c''' option.
ColorYUV(gain_y={{BoldColor|blue|100|2.0}}, cont_u={{BoldColor|blue|100|1.2}}, cont_v={{BoldColor|blue|100|0.8}}, {{FuncArg|f2c}}=true)

</div>
</div>

== Conditional Variables ==
<div style="max-width:62em" >
The global variables "coloryuv_xxx" with xxx = gain_y, gain_u, gain_v, bright_y, bright_u, bright_v, gamma_y, contrast_y, contrast_u or contrast_v are read each frame, and applied. It is possible to modify these variables using [[FrameEvaluate]] or [[ConditionalReader]].

For example:

coloryuvoffset.txt:
<div {{BoxWidthIndent|56|2}} >
Type float
Default 0.0

I 25 50 0.0 255.0
R 75 225 128.0
I 250 275 255.0 0.0
</div>

the script:
<div {{BoxWidthIndent|56|2}} >
Colorbars(512,256).ConvertToYV12.Trim(0,299)
ColorYUV(cont_y=10, conditional=true)
ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false)
ShowFrameNumber()
</div>

So up to frame 25 gain_y is equal to the default (which is 0.0), for frame 25 up to 50 the gain_y is increased from 0.0 to 255.0, etc ...

There are more examples of conditional modification at the [[ConditionalReader]] page.
</div>

<div style="max-width:62em" >
* Adjust ''Y ''(luma) gamma and offset (brightness), while increasing chroma ''U ''(yellow-blue) offset (away from yellow and toward blue)
<div {{BoxWidthIndent|56|2}} >

</div>

* {{FuncArg|autogain}} and {{FuncArg|autowhite}}: recovers visibility on "very bad" recordings:
<div {{BoxWidthIndent|56|2}} >
ColorYUV(autogain=true, autowhite=true)
</div>

* {{FuncArg|showyuv}}: show all colors in the [[YUV]] space. Requires a YUV clip as input.
:Returns a [[YV12]], 448x448 clip with source frame rate, duration and audio.
:'''Note''', not all colors are convertible to RGB - see [http://forum.doom9.org/showthread.php?t=154731 this discussion on doom9].

:Frame 0 luma is 16{{D}}, frame 1 luma is 17{{D}} and so on.
:{{AvsPluscon}} Size changes depending on options selected:
:*By default size is 450x450.

:* The expression to be evaluated comes from a file instead of a string;

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >

:If {{FuncArg|index}} is out of range, an error is raised.

Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''

function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >

...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track.

: This group of functions return the absolute difference of pixel value between the current and next frame of {{FuncArg|clip}} – either the combined RGB difference or the Luma, U-chroma or V-chroma differences, respectively. In v2.61 an {{FuncArg|offset}} argument is added, which enables you to access the difference between the RGB, luma or chroma plane of the current frame and of ''any'' other frame. Note that for example clip.'''RGBDifferenceToNext'''(-1) = clip.'''RGBDifferenceToPrevious''', and clip.'''RGBDifferenceToNext'''(0) = 0.

: This group of functions return statistics about the distribution of pixel values on a plane (Luma, U-chroma and V-chroma, respectively). The statistics are, in order of presentation: maximum, minimum, median and range (maximum - minimum difference).
: {{FuncArg|threshold}} is a percentage, stating how many percent of the pixels are allowed above or below minimum. The threshold is optional and defaults to 0. In v2.61 an {{FuncArg|offset}} argument is added, which enables you to access the statistics of other frames than the current one.

{{ScriptFunctionH5|Import||Import(filename)}}
{{ScriptFunctionCode|Import||Import(filename [, ...] [, bool utf8])}} {{AvsPluscon}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.
:* {{FuncArg|utf8}} {{AvsPluscon}} if true, assumes filename(s) are [[wikipedia:UTF-8|UTF8]], else (default), assume ANSI.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >
ColorBars
A=Subtitle("A", align=5) ## create clip 'A'

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''

# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])

index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''

: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have

</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

: This group of functions return statistics about the distribution of pixel values on a plane (Luma, U-chroma and V-chroma, respectively). The statistics are, in order of presentation: maximum, minimum, median and range (maximum - minimum difference).
: {{FuncArg|threshold}} is a percentage, stating how many percent of the pixels are allowed above or below minimum. The threshold is optional and defaults to 0. In v2.61 an {{FuncArg|offset}} argument is added, which enables you to access the statistics of other frames than the current one.

# median and average are close only on even distributions;
# this can be a useful diagnostic

ColorYUV

2018-03-05T00:42:03Z

Raffriff42: update for AVS+ r2632

<div style="max-width:62em" >
'''ColorYUV''' has many different methods of changing the color and luminance of your images. Gain, offset, gamma and contrast can be set independently on each channel. Also included are two 'auto' modes, an analysis function and a color gamut generator.

All settings for this filter are optional. All values are defaulting to "0" or false.

[[RGBAdjust]] works in a similar manner for [[RGB]] clips.

* In AviSynth 2.6, all [[YUV]] color formats are supported ([[Y8]], [[YV12]], [[YV16]], [[YV24]], [[YV411]] and [[YUY2]])
* {{AvsPluscon}} all non-[[Float_(color_format)|Float]] [[YUV]] and [[YUVA]] color formats are supported.
* {{AvsPluscon}} all parameters are [[Autoscale_parameter|autoscaling]] – they work without changes at all bit depths.

::If ''true, ''this option will use the information from the analyzer, and attempt to create as good contrast as possible. That means, it will scale up the ''Y ''(luma) values to match the minimum and maximum values.

:{{Par2|f2c|bool|false}}
::{{AvsPluscon}} If ''true,'' perform [[#Parameter Rescaling|''parameter rescaling'']] as decribed below on all '''cont_'''''x'', '''gain_'''''x'' and '''gamma_'''''x'' arguments.
::For example, with {{FuncArg|f2c}}=''true'', {{FuncArg|cont_u}}=1.2 results in a 20% increase in ''U'' channel "saturation".
</div>

==Parameter Rescaling==
<div style="max-width:62em" >
The quantities ''saturation'', ''contrast'' and ''brightness'' (as in [[Tweak]] for example) are connected with quantities in this filter by the following equations:
* {{FuncArg|cont_u}} = {{FuncArg|cont_v}} = ({{BoldColor|darkblue|100|sat}}-1) * 256
* {{FuncArg|gain_y}} = ({{BoldColor|darkblue|100|cont}}-1) * 256
* {{FuncArg|off_y}} = {{BoldColor|darkblue|100|bright}}
A saturation of 0.8 gives for example: cont_u = cont_v = -0.2 * 256 = -51.2.

Note that in [[Tweak]] your YUV values will always be clipped to valid TV-ranges, but here you have to specify {{FuncArg|opt}}="coring".

You can add a simple [[User_defined_script_functions|user function]] to rescale or translate from familiar "Tweak-like" units to ColorYUV units:
<div {{BoxWidthIndent|56|2}} >
function f2c(float f) {
return (f - 1.0) * 256.0
}

## usage example:
ColorYUV(gain_y=f2c({{BoldColor|blue|100|2.0}}), cont_u=f2c({{BoldColor|blue|100|1.2}}), cont_v=f2c({{BoldColor|blue|100|0.8}})

## that is, gain is 200%, and contrast (saturation)
## is +20% in the U channel, -20% in the V channel.

## ...which specified normally, would look like this:
ColorYUV(gain_y={{BoldColor|blue|100|256}}, cont_u={{BoldColor|blue|100|51.2}}, cont_v={{BoldColor|blue|100|-51.2}})
</div>
</div>

== Conditional Variables ==
<div style="max-width:62em" >
The global variables "coloryuv_xxx" with xxx = gain_y, gain_u, gain_v, bright_y, bright_u, bright_v, gamma_y, contrast_y, contrast_u or contrast_v are read each frame, and applied. It is possible to modify these variables using [[FrameEvaluate]] or [[ConditionalReader]].

For example:

coloryuvoffset.txt:
<div {{BoxWidthIndent|56|2}} >
Type float
Default 0.0

I 25 50 0.0 255.0
R 75 225 128.0
I 250 275 255.0 0.0
</div>

the script:
<div {{BoxWidthIndent|56|2}} >
Colorbars(512,256).ConvertToYV12.Trim(0,299)
ColorYUV(cont_y=10, conditional=true)
ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false)
ShowFrameNumber()
</div>

So up to frame 25 gain_y is equal to the default (which is 0.0), for frame 25 up to 50 the gain_y is increased from 0.0 to 255.0, etc ...

There are more examples of conditional modification at the [[ConditionalReader]] page.

Histogram
</div>

[[File:histogram_classic.jpg]]

Available in [[YUV]] color formats only. For [[RGB]] sources, try [[Histograms_in_RGB_%26_CMY#HistogramRGBParade|'''HistogramRGBParade''']].

This will add a per-line luminance graph (usually called a [[wikipedia:Waveform_monitor|Waveform Monitor]]) on the right side of the video, increasing clip.[[Clip_properties|Width]] by 256. The left side of the graph represents luma=0 and the right side represents luma=255. Values outside the [[Limiter|valid CCIR-601 range]] are shown with a brown/yellowish color background; a greenish line represents Y=128.

If you prefer to see luma=0 on bottom and luma=255 on top, use this:
<div {{BoxWidthIndent|24|4}} >
[[TurnRight]].Histogram.[[TurnLeft]]
</div>

::[[File:Histogram_classic-v2-turned.jpg]]

</div>

----
=== Levels mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("levels")
</div>

[[File:Histogram-vortex-levels.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]]. For [[RGB]] sources, try [[Histograms_in_RGB_%26_CMY#HistogramRGBLevels_.2F_HistogramCMYLevels|'''HistogramRGBLevels''']].

This mode will display three histograms on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. This will show the distribution of the ''Y'', ''U'' and ''V'' components in the current frame.

The top graph displays the ''Y'' (luma) distribution of the frame, where the left side represents Y=0 and the right side represents Y=255. Values outside the [[Limiter|valid CCIR601 range]] have been indicated with faded colors; Y=128 has been marked with a dotted line. The vertical axis shows the number of pixels for a given luma (Y) value.

The middle graph is similar, and displays the ''U'' component; the bottom graph displays the ''V'' component.

The {{FuncArg|factor}} option (100.0 by default) specifies how the histograms are displayed, exaggerating the vertical scale. It is specified as percentage of the total population (that is number of luma or chroma pixels in a frame). For example:
<div {{BoxWidthIndent|24|0}} >
Histogram("levels", 0.5)
</div>

[[File:Histogram-vortex-levels-v3-levels0,5.jpg]]

'''NOTE''', {{FuncArg|factor}} is an ''unnamed ''optional argument; <br style="line-height:60%" />
<code>Histogram(mode="levels", '''factor='''0.5)</code> will not work, but <code>Histogram("levels", 0.5)</code> works fine.
</div>

----
=== Color mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("color")
</div>

[[File:Histogram-vortex-color.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]].

This mode will display the chroma values (U/V color placement) in a two dimensional graph (called a [[wikipedia:Vectorscope|vectorscope]]) on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. It can be used to read of the [[wikipedia:Hue|hue]] and [[wikipedia:Colorfulness#Saturation|saturation]] of a clip. At the same time it is a histogram: the whiter a pixel in the vectorscope, the more pixels of the input clip correspond to that chroma value. The lighter background denotes the [[Limiter|valid CCIR-601 range]].

<div id="colorvector">
{| border="0"
|
[[File:Labeled-vector6b.png|left|Histogram("color") output with added labels]]
|style="vertical-align:top; margin-right:10%"|
Labels have been added to this vectorscope image for explication purposes, showing the ''U'' and ''V'' axes and degrees of hue. Spots have also been added, showing 75% saturated [[ColorBars]] (clockwise from 0°: blue, magenta, red, yellow, green and cyan).

The ''U'' component is displayed on the horizontal (X) axis, with U=0 on the left and U=255 on the right. The ''V'' component is displayed on the vertical (Y) axis, with V=0 on the top and V=255 on the bottom.

The position of a spot on the scope corresponds to a chroma value from the input clip. The graph can be used to read ''hue'' and ''saturation''. As the hue of a color changes, the spot moves around the center. As the saturation changes, it moves in or out from the center. The center is where ''U'' and ''V'' equal 128, the saturation is zero and the corresponding pixel has no color. As you increase the saturation, the spot moves towards the edge.
|}</div>
At U=255, V=128 the hue is zero (blue) and the saturation is at maximum, that is, <br>

::saturation = sqrt( (U-128)<sup>2</sup> + (V-128)<sup>2</sup> ) or 127 <br>

When turning hue clockwise 90 degrees, the chroma is given by U=128, V=255 (red, approximately). Keeping the hue constant and decreasing the saturation, means that we move from the circle to the center of the vectorscope. Thus the color flavor remains the same, only it fades slowly to [[GreyScale|greyscale]].
</div>

----
=== Color2 mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("color2")
</div>

[[File:Histogram-vortex-color2.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]].

This mode will display the pixels in a two dimensional graph (called a [[wikipedia:Vectorscope|vectorscope]]) on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. It can be used to read of the [[wikipedia:Hue|hue]] and [[wikipedia:Colorfulness#Saturation|saturation]] of a clip.

The ''U'' component is displayed on the horizontal (X) axis, with the leftmost side being U=0 and the rightmost side being U=255. The ''V'' component is displayed on the vertical (Y) axis, with the top representing V=0 and the bottom representing V=255. The white square denotes the [[Limiter|valid CCIR-601 range]].

<div id="colorvector">
{| border="0"
|
[[File:Labeled-vector-color2.png|left|Histogram("color2") output with added labels]]
|style="vertical-align:top; margin-right:10%"| As [[#colorvector|above]], labels and [[ColorBars]] dots have been added to this vectorscope image for explication purposes.

The position of a spot on the scope corresponds to a chroma value from the input clip, exactly as with <code>[[#Color mode|Histogram("color")]]</code>, but the spot is brighter and in color.

'''Color2 mode''' is also different from '''Color mode''' in that the background is black instead of shaded, and a ''color wheel'' around the circumference of the scope has been added, divided into six hues (clockwise from 0°: blue, magenta, red, yellow, green and cyan), with white tick marks at 15 degree intervals.
|}</div>
</div>

----
=== Luma mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("luma")
</div>

[[Image:histogram_modeluma.jpg]]

Available in [[YUV]] [[Planar|planar]] and [[YUY2]] color formats.

This mode will amplify luminance, and display very small luminance variations. This is good for detecting blocking and noise, and can be helpful at adjusting filter parameters. In this mode a 1 pixel luminance difference will show as a 16 pixel luminance pixel, thus seriously enhancing small flaws.
</div>

----
=== Audiolevels mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("audiolevels")
</div>

[[Image:histogram_audiolevels.jpg]]

[[YUV]] [[Planar|planar]] video is required. Audio is [[ConvertAudio|converted]] to 16 bit.

Shows the audio levels in [[wikipedia:Decibel|decibels]] for each channel present. For example, if the source has six channels of audio, six vertical bars will be shown.

* The green bars show the {{Serif|''RMS''}} ([[wikipedia:Root_mean_square|Root Mean Square]]) level of the audio in each video frame (let's say {{Serif|''n''}} samples) using the following formula:

::[[File:Histogram-eq-1.png|x46px|<math> RMS = 20 \cdot log_{10}( 1/32768 \cdot \sqrt{ 1/n \cdot \sum_{j=1}^{n} sample(j)^{2}} ) </math>]]

* The blue bars show the {{Serif|''max''}} (peak) level of the audio in each video frame using the following formula:

::[[File:Histogram-eq-2.png|x16px|<math> max = 20 \cdot log_{10}(max_{j} (sample(j)) / 32768) </math>]]

The maximum possible level without [[wikipedia:Clipping_%28audio%29|clipping]] is 0 dB by definition. The minimum level for 16 bit audio is therefore

::[[File:Histogram-eq-4.png|x16px|<math> 20 \cdot log_{10}(1/32768) = - 90.31 \ dB </math>]]    (since 2<sup>16</sup> / 2 = 32768)
</div>

----
=== Stereo, StereoY8 and StereoOverlay mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("stereo")
</div>

[[Image:histogram_modestereo.gif|256px|]]

Requires a source clip with stereo audio; '''StereoOverlay''' also requires a source clip with a [[YUV]] [[Planar|planar]] color format.

These modes show a classic stereo graph (or [[wikipedia:Lissajous_curve|Lissajous]] pattern) from the clip audio, often seen in recording studios. They are used to view the left-right phase distribution of the input signal. In-phase stereo appears predominantly vertical (as shown), but incorrectly phased stereo appears predominantly horizontal. Two-channel Mono appears as a vertical line.

'''StereoOverlay''' will overlay the graph on top of the original. Each frame will contain only information from the current frame to the beginning of the next frame. The signal is linearly upsampled 8x, to provide clearer visuals. '''Stereo''' and '''StereoY8''' won't overlay the graph on the video, but will just return the graph alone as a 512×512 video clip (in [[YV12]] or [[Y8]] format respectively).

Histogram
</div>

[[File:histogram_classic.jpg]]

Available in [[YUV]] color formats only. For [[RGB]] sources, try [[Histograms_in_RGB_%26_CMY#HistogramRGBParade|'''HistogramRGBParade''']].

This will add a per-line luminance graph (usually called a [[wikipedia:Waveform_monitor|Waveform Monitor]]) on the right side of the video, increasing clip.[[Clip_properties|Width]] by 256. The left side of the graph represents luma=0 and the right side represents luma=255. Values outside the [[Limiter|valid CCIR-601 range]] are shown with a brown/yellowish color background; a greenish line represents Y=128.

If you prefer to see luma=0 on bottom and luma=255 on top, use this:
<div {{BoxWidthIndent|24|4}} >
[[TurnRight]].Histogram.[[TurnLeft]]
</div>

----
=== Levels mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("levels")
</div>

[[File:Histogram-vortex-levels.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]]. For [[RGB]] sources, try [[Histograms_in_RGB_%26_CMY#HistogramRGBLevels_.2F_HistogramCMYLevels|'''HistogramRGBLevels''']].

This mode will display three histograms on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. This will show the distribution of the ''Y'', ''U'' and ''V'' components in the current frame.

The top graph displays the ''Y'' (luma) distribution of the frame, where the left side represents Y=0 and the right side represents Y=255. Values outside the [[Limiter|valid CCIR601 range]] have been indicated with faded colors; Y=128 has been marked with a dotted line. The vertical axis shows the number of pixels for a given luma (Y) value.

The middle graph is similar, and displays the ''U'' component; the bottom graph displays the ''V'' component.

The {{FuncArg|factor}} option (100.0 by default) specifies how the histograms are displayed, exaggerating the vertical scale. It is specified as percentage of the total population (that is number of luma or chroma pixels in a frame). For example:
<div {{BoxWidthIndent|24|0}} >
Histogram("levels", 0.5)
</div>

[[File:Histogram-vortex-levels-v3-levels0,5.jpg]]

'''NOTE''', {{FuncArg|factor}} is an ''unnamed ''optional argument; <br style="line-height:60%" />
<code>Histogram(mode="levels", '''factor='''0.5)</code> will not work, but <code>Histogram("levels", 0.5)</code> works fine.
</div>

----
=== Color mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("color")
</div>

[[File:Histogram-vortex-color.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]].

This mode will display the chroma values (U/V color placement) in a two dimensional graph (called a [[wikipedia:Vectorscope|vectorscope]]) on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. It can be used to read of the [[wikipedia:Hue|hue]] and [[wikipedia:Colorfulness#Saturation|saturation]] of a clip. At the same time it is a histogram: the whiter a pixel in the vectorscope, the more pixels of the input clip correspond to that chroma value. The lighter background denotes the [[Limiter|valid CCIR-601 range]].

<div id="colorvector">
{| border="0"
|
[[File:Labeled-vector6b.png|left|Histogram("color") output with added labels]]
|style="vertical-align:top; margin-right:10%"|
Labels have been added to this vectorscope image for explication purposes, showing the ''U'' and ''V'' axes and degrees of hue. Spots have also been added, showing 75% saturated [[ColorBars]] (clockwise from 0°: blue, magenta, red, yellow, green and cyan).

The ''U'' component is displayed on the horizontal (X) axis, with U=0 on the left and U=255 on the right. The ''V'' component is displayed on the vertical (Y) axis, with V=0 on the top and V=255 on the bottom.

The position of a spot on the scope corresponds to a chroma value from the input clip. The graph can be used to read ''hue'' and ''saturation''. As the hue of a color changes, the spot moves around the center. As the saturation changes, it moves in or out from the center. The center is where ''U'' and ''V'' equal 128, the saturation is zero and the corresponding pixel has no color. As you increase the saturation, the spot moves towards the edge.
|}</div>
At U=255, V=128 the hue is zero (blue) and the saturation is at maximum, that is, <br>

::saturation = sqrt( (U-128)<sup>2</sup> + (V-128)<sup>2</sup> ) or 127 <br>

When turning hue clockwise 90 degrees, the chroma is given by U=128, V=255 (red, approximately). Keeping the hue constant and decreasing the saturation, means that we move from the circle to the center of the vectorscope. Thus the color flavor remains the same, only it fades slowly to [[GreyScale|greyscale]].
</div>

----
=== Color2 mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("color2")
</div>

[[File:Histogram-vortex-color2.jpg]]

Available in all [[YUV]] [[Planar|planar]] color formats, except [[Y8]].

This mode will display the pixels in a two dimensional graph (called a [[wikipedia:Vectorscope|vectorscope]]) on the right side of the video frame, increasing clip.[[Clip_properties|Width]] by 256. It can be used to read of the [[wikipedia:Hue|hue]] and [[wikipedia:Colorfulness#Saturation|saturation]] of a clip.

The ''U'' component is displayed on the horizontal (X) axis, with the leftmost side being U=0 and the rightmost side being U=255. The ''V'' component is displayed on the vertical (Y) axis, with the top representing V=0 and the bottom representing V=255. The white square denotes the [[Limiter|valid CCIR-601 range]].

<div id="colorvector">
{| border="0"
|
[[File:Labeled-vector-color2.png|left|Histogram("color2") output with added labels]]
|style="vertical-align:top; margin-right:10%"| As [[#colorvector|above]], labels and [[ColorBars]] dots have been added to this vectorscope image for explication purposes.

The position of a spot on the scope corresponds to a chroma value from the input clip, exactly as with <code>[[#Color mode|Histogram("color")]]</code>, but the spot is brighter and in color.

'''Color2 mode''' is also different from '''Color mode''' in that the background is black instead of shaded, and a ''color wheel'' around the circumference of the scope has been added, divided into six hues (clockwise from 0°: blue, magenta, red, yellow, green and cyan), with white tick marks at 15 degree intervals.
|}</div>
</div>

----
=== Luma mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("luma")
</div>

[[Image:histogram_modeluma.jpg]]

Available in [[YUV]] [[Planar|planar]] and [[YUY2]] color formats.

This mode will amplify luminance, and display very small luminance variations. This is good for detecting blocking and noise, and can be helpful at adjusting filter parameters. In this mode a 1 pixel luminance difference will show as a 16 pixel luminance pixel, thus seriously enhancing small flaws.
</div>

----
=== Audiolevels mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("audiolevels")
</div>

[[Image:histogram_audiolevels.jpg]]

[[YUV]] [[Planar|planar]] video is required. Audio is [[ConvertAudio|converted]] to 16 bit.

Shows the audio levels in [[wikipedia:Decibel|decibels]] for each channel present. For example, if the source has six channels of audio, six vertical bars will be shown.

* The green bars show the {{Serif|''RMS''}} ([[wikipedia:Root_mean_square|Root Mean Square]]) level of the audio in each video frame (let's say {{Serif|''n''}} samples) using the following formula:

::[[File:Histogram-eq-1.png|x46px|<math> RMS = 20 \cdot log_{10}( 1/32768 \cdot \sqrt{ 1/n \cdot \sum_{j=1}^{n} sample(j)^{2}} ) </math>]]

* The blue bars show the {{Serif|''max''}} (peak) level of the audio in each video frame using the following formula:

::[[File:Histogram-eq-2.png|x16px|<math> max = 20 \cdot log_{10}(max_{j} (sample(j)) / 32768) </math>]]

The maximum possible level without [[wikipedia:Clipping_%28audio%29|clipping]] is 0 dB by definition. The minimum level for 16 bit audio is therefore

::[[File:Histogram-eq-4.png|x16px|<math> 20 \cdot log_{10}(1/32768) = - 90.31 \ dB </math>]]    (since 2<sup>16</sup> / 2 = 32768)
</div>

----
=== Stereo, StereoY8 and StereoOverlay mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("stereo")
</div>

[[Image:histogram_modestereo.gif|256px|]]

Requires a source clip with stereo audio; '''StereoOverlay''' also requires a source clip with a [[YUV]] [[Planar|planar]] color format.

These modes show a classic stereo graph (or [[wikipedia:Lissajous_curve|Lissajous]] pattern) from the clip audio, often seen in recording studios. They are used to view the left-right phase distribution of the input signal. In-phase stereo appears predominantly vertical (as shown), but incorrectly phased stereo appears predominantly horizontal. Two-channel Mono appears as a vertical line.

'''StereoOverlay''' will overlay the graph on top of the original. Each frame will contain only information from the current frame to the beginning of the next frame. The signal is linearly upsampled 8x, to provide clearer visuals. '''Stereo''' and '''StereoY8''' won't overlay the graph on the video, but will just return the graph alone as a 512×512 video clip (in [[YV12]] or [[Y8]] format respectively).

Histogram("audiolevels")
</div>

[[Image:histogram_audiolevels.jpg]]

[[YUV]] [[Planar|planar]] video is required. Audio is [[ConvertAudio|converted]] to 16 bit.

Shows the audio levels in [[wikipedia:Decibel|decibels]] for each channel present. For example, if the source has six channels of audio, six vertical bars will be shown.

* The green bars show the {{Serif|''RMS''}} ([[wikipedia:Root_mean_square|Root Mean Square]]) level of the audio in each video frame (let's say {{Serif|''n''}} samples) using the following formula:

::[[File:Histogram-eq-1.png|x46px|<math> RMS = 20 \cdot log_{10}( 1/32768 \cdot \sqrt{ 1/n \cdot \sum_{j=1}^{n} sample(j)^{2}} ) </math>]]

* The blue bars show the {{Serif|''max''}} (peak) level of the audio in each video frame using the following formula:

::[[File:Histogram-eq-2.png|x16px|<math> max = 20 \cdot log_{10}(max_{j} (sample(j)) / 32768) </math>]]

The maximum possible level without [[wikipedia:Clipping_%28audio%29|clipping]] is 0 dB by definition. The minimum level for 16 bit audio is therefore

::[[File:Histogram-eq-4.png|x16px|<math> 20 \cdot log_{10}(1/32768) = - 90.31 \ dB </math>]]    (since 2<sup>16</sup> / 2 = 32768)

=== Stereo, StereoY8 and StereoOverlay mode ===
<div style="max-width:62em" >
<div {{BoxWidthIndent|24|0}} >
Histogram("stereo")
</div>

[[Image:histogram_modestereo.gif|256px|]]

Requires a source clip with stereo audio; '''StereoOverlay''' also requires a source clip with a [[YUV]] [[Planar|planar]] color format.

These modes show a classic stereo graph (or [[wikipedia:Lissajous_curve|Lissajous]] pattern) from the clip audio, often seen in recording studios. They are used to view the left-right phase distribution of the input signal. In-phase stereo appears predominantly vertical (as shown), but incorrectly phased stereo appears predominantly horizontal. Two-channel Mono appears as a vertical line.

'''StereoOverlay''' will overlay the graph on top of the original. Each frame will contain only information from the current frame to the beginning of the next frame. The signal is linearly upsampled 8x, to provide clearer visuals. '''Stereo''' and '''StereoY8''' won't overlay the graph on the video, but will just return the graph alone as a 512×512 video clip (in [[YV12]] or [[Y8]] format respectively).

Raffriff42: DevIL pixel formats

__TOC__

== ImageReader and ImageSource ==
<div style="max-width:62em" >
{{Func2Def
|ImageReader(string ''file'', int ''start'', int ''end'', float ''fps'', bool ''use_DevIL'', bool ''info'', string ''pixel_type'')
|ImageSource(string ''file'', int ''start'', int ''end'', float ''fps'', bool ''use_DevIL'', bool ''info'', string ''pixel_type'')}}

:{{Par2|file|string|"c:\%06d.ebmp"}}
::Template for the image file(s), where frame number substitution can be specified using [http://www.cplusplus.com/reference/clibrary/cstdio/sprintf/ sprintf syntax]. For example, the files written by [[ImageWriter|ImageWriter's]] default parameters can be referenced with "c:\%06d.ebmp". If {{FuncArg|file}} points to a single file (no sprintf pattern), then that file is read once and the image subsequently returned for all requested frames.

::If you see the error message '''''ImageReader: error 'could not open file' in DevIL library''''' it may mean that a {{FuncArg|file}} was not found or does not exist; see [[#Notes|Notes]] below.

:{{Par2|start|int|0}}
:{{Par2|end|int|1000}}
::Specifies the starting and ending numbers used for filename generation. The file corresponding to {{FuncArg|start}} is always frame 0 in the clip, the file corresponding to {{FuncArg|end}} is frame (end-start). The resulting clip has ({{FuncArg|end}} - {{FuncArg|start}} + 1) frames. '{{FuncArg|end}}=0' does NOT mean 'no upper bound' as with [[ImageWriter]]. The first file in the sequence, i.e., corresponding to {{FuncArg|start}}, MUST exist in order for clip parameters to be computed. Any missing files in the sequence are replaced with a blank frame.

:{{Par2|fps|float|24.0}}
::Frames Per Second of returned clip.

:{{Par2|use_DevIL|bool|false}}
::When false (the default), give the ''Developer's Image Library'' ([http://openil.sourceforge.net/ DevIL]) lower priority, using the internal BMP/[[ImageWriter#The_EBMP_Format|EBMP]] parser whenever possible; when true, always use DevIL, bypassing the internal parser.
<div {{NotaBeneWidthIndent|58|4}} >
When {{FuncArg|use_DevIL}}=false, an attempt is made to parse files with the internal BMP/EBMP parser; upon failure – that is, for all image files which are not (E)BMP – [http://openil.sourceforge.net/ DevIL] is utilized. When {{FuncArg|use_DevIL}}=true, execution skips the internal parser and goes directly to DevIL. You should only need to use {{FuncArg|use_DevIL}}=true if you have (E)BMP files you don't want read by '''ImageReader''''s internal parser. See [[#Notes|Notes]] below for DevIL library details.
</div>

:{{Par2|info|bool|false}}
::When true, the source filename and [http://openil.sourceforge.net/ DevIL] version is written to each video frame.

:{{Par2|pixel_type|string|"RGB24"}}
::Specifies the output pixel format:
::*If {{FuncArg|use_DevIL}}=true, [[Y8]] (8-bit greyscale), [[RGB24]] and [[RGB32]] are supported.
:::{{AvsPluscon}} also supports their 16-bit counterparts: [[Avisynthplus_color_formats|Y16]], [[Avisynthplus_color_formats|RGB48]] and [[Avisynthplus_color_formats|RGB64]].
:::The alpha channel is loaded only for RGB32/64 and only if DevIL supports it for the loaded image format.
::*If {{FuncArg|use_DevIL}}=false, must be empty ''except'' when decoding a 12 bit, 3 plane EBMP;
:::in that case, {{FuncArg|pixel_type}} must be either [[YV12]] (the default) or [[YV411]].

'''ImageReader''' is present from v2.52, replacing [http://www.avisynth.nl/users/warpenterprises/ WarpEnterprises'] ''ImageSequence'' plugin.

'''ImageSource''' is equivalent, with some minor functionality changes. ImageSource is faster than ImageReader when importing a single picture.

===== ''Output Formats'' =====
:For BMP or EBMP images opened with the internal parser, the video output is set when the sequence was created (see [[ImageWriter#The_EBMP_Format|ImageWriter: The EBMP Format]]); for images opened with the [http://openil.sourceforge.net/ DevIL] library, the video output is as decribed under {{FuncArg|pixel_type}} above.

===== ''Input Formats'' =====
:All AviSynth [[Color_spaces|color spaces]] are supported.

:[[Wikipedia:BMP_file_format|BMP]] and EBMP are supported natively (see [[#Notes|Notes]] below); with DevIL 1.7.8, supported image formats are:
: [[Wikipedia:DirectDraw_Surface|dds]],  [[Wikipedia:JPEG|jpg/jpe/jpeg]],  [[Wikipedia:PCX|pcx]],  [[Wikipedia:Portable_Network_Graphics|png]],  [[Wikipedia:Netpbm_format|pbm/pgm/ppm]],  [[Wikipedia:TGA|tga]],  [[Wikipedia:TIFF|tif/tiff]],

:{{Par2|file|string|}}
::animation file to be loaded.

::If you see the error message '''''ImageSourceAnim: error 'could not open file' in DevIL library''''' it may mean that the {{FuncArg|file}} was not found or does not exist; see [[#Notes|Notes]] below.

:{{Par2|fps|float|24.0}}
::Frames Per Second of returned clip.

:{{Par2|info|bool|false}}
::When true, the source filename and DevIL version is written to each video frame.

:{{Par2|pixel_type|string|"RGB32"}}
::Specifies the output pixel format: [[Y8]] (8-bit greyscale), [[RGB24]] and [[RGB32]] are supported.
:::{{AvsPluscon}} also supports their 16-bit counterparts: [[Avisynthplus_color_formats|Y16]], [[Avisynthplus_color_formats|RGB48]] and [[Avisynthplus_color_formats|RGB64]].
:::The alpha channel is loaded only for RGB32/64 and only if DevIL supports it for the loaded image format.

'''ImageSourceAnim''' lets you import animations ([[Wikipedia:GIF|gif]], [[Wikipedia:Netpbm_format|ppm]], [[Wikipedia:TIFF|tif/tiff]] or [[Wikipedia:Adobe_Photoshop#File_format|psd]]). If there is a delay between the first and second image in the animation, the framerate is set accordingly. If this delay is zero, the framerate is set to 24 fps by default (and can be adjusted by setting the {{FuncArg|fps}} parameter). If the images in the animation have unequal dimensions, then the dimension of the first image is taken and the remaining images are padded with black pixels below and or to the right. Note that unlike '''ImageReader''' and '''ImageSource''', {{FuncArg|pixel_type}} is set to RGB32 by default.

ImageSourceAnim requires DevIL 1.7.8, included in the Avisynth installation (see [[#Notes|Notes]] below).

* "EBMP" is an AviSynth extension of the standard Microsoft RIFF image format that allows you to save raw image data (all color formats are supported). See [[ImageWriter#The_EBMP_Format|ImageWriter]] for more details.
* Since v2.61 DevIL.dll is delay loaded, so Avisynth.dll can be used without it, in which case ImageReader/Writer would support only ebmp mode.
* Greyscale BMPs are not read and written correctly by DevIL. They should be opened using '''use_DevIL=false'''.
* [http://openil.sourceforge.net/ DevIL] 1.7.8 is included in the Avisynth installation since v2.61. If you need to download it, it is available [https://sourceforge.net/projects/openil/files/DevIL%20Win32/1.7.8/DevIL-EndUser-x86-1.7.8.zip here]. Just put the DevIL.dll in your system folder (it will overwrite any older version). Be sure to use the non-unicode version, because the other one will result in crashes when loading pictures.
*DevIL.dll 1.7.8 requires the 2005 VC [https://support.microsoft.com/en-us/kb/2977003 runtime libraries] to be correctly installed: [http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en Visual C++ 2005 SP1 Redistributable Package (x86)].
* Loading DIB/BMP type files that use a palette (such as 8 bit RGB, Monochrome, RLE8 and RLE4) requires DevIL 1.7.8. (Because the failure was usually catastrophic, internal BMP processing does not automatically fail over to DevIL processing. Forcing DevIL processing when using DevIL 1.6.6 for these file types is not recommended.)

{{ScriptFunctionH5|Defined||Defined(var)}}
: Tests if {{FuncArg|var}} is defined. Can be used inside [[Script_functions]] to test if an optional argument has been given an explicit value.
: More formally, the function returns false if its argument (normally a function argument or variable) has the void ('undefined') type, otherwise it returns true.
''Examples:''

{{ScriptFunctionH5|FunctionExists|{{AvsPluscon}}|FunctionExists(name)}}
: Tests if the function or filter name is defined in the script.
: {{FuncArg|name}} can be any string – it does not need to be a [[Script_variables#Variable_Names|legal name]].
: ''Example'' – see [[#Apply|Apply]] below

{{ScriptFunctionH5|InternalFunctionExists|{{AvsPluscon}}|InternalFunctionExists(name)}}
: Tests if the function, filter or [[Clip_properties|property]] name is defined natively within [[AviSynth+]].
:* Unlike [[#FunctionExists|FunctionExists]], returns ''false'' for [[Plugins|external plugins]] and [[User_functions|user-defined functions]].
</div>

== Control functions ==

: These facilitate flow of control (loading of scripts, arguments checks, global settings adjustment, etc.).

{{ScriptFunctionH5|Apply||Apply(string ''func_string'' [, arg1 [, arg2 [, ... [, arg''n'']]]] )}}
: Calls the function or filter {{FuncArg|func_string}} with arguments {{FuncArg|arg1}}, {{FuncArg|arg2}}, ..., {{FuncArg|arg''n''}} (as many as supplied).
:* This provides a way to call a function or filter '''by name''', with arguments.
:* <code>Apply("f", x)</code> is equivalent to <code>f(x)</code>
:* <code>Apply("f", x)</code> is equivalent to <code>[[#Eval|Eval]]("f(" + String(x) + ")")</code>
:* Note that the clip argument must be supplied explicitly - the [[Last|special variable ''Last'']] is not used.
''Examples:''

{{ScriptFunctionH5|Eval||Eval(expression [, string ''name''])}}
: Evaluates an arbitrary {{FuncArg|expression}} and returns the result of that evaluation. '''It works exactly like [[#Import|Import]] below''', except
:* The expression to be evaluated comes from a string instead of a file;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are not changed;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is not changed.
: Argument {{FuncArg|name}} will be shown in the error message beside the script name. Both will be followed with the line number in {{FuncArg|expression}} where the error occurred.

: Variables in your calling script are available within {{FuncArg|expression}}; [[Global|global variables]] are not required.
: Note '''Eval''' can return the result of ''any'' valid expression; usually a clip, but also a string, boolean etc.
: You can use '''Eval''' to construct and evaluate expressions dynamically inside your scripts, based on variable input data.
: '''Eval''' is useful as a [[Control_structures|control structure]] for creating multi-line ''block statements'' without requiring [[AviSynth%2B|AviSynth+]].
: '''Eval''' can be used to put aside the need to install external plugins if they are not actually used.

{{ScriptFunctionH5|Import||Import(filename)}}
{{ScriptFunctionCode|Import||Import(filename [, ...] [, bool utf8])}} {{AvsPluscon}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.
:* {{FuncArg|utf8}} {{AvsPluscon}} if true, assumes filename(s) are [[wikipedia:UTF-8|UTF8]], else (default), assume ANSI.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# ''B.avsi''
A.Invert
</div><div {{BoxWidthIndent|56|2}} >
ColorBars
A=Subtitle("A", align=5) ## create clip 'A'
Import("B.avsi")
return Last ## returns clip 'A' with colors inverted
</div>

<div {{BoxWidthIndent|56|2}} >
## here we do not care about the return value (''mylib.avsi'' contains only functions)
Import("mylib.avsi")
...
## ''mysources.avsi'' loads predetermined file names from a folder into globals
okflag = Import("mysources.avsi")
source = okflag ? global1 + global2 + global3 : [[BlankClip]]()
</div>

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])
</div>

Note - all branches are evaluated:
<div {{BoxWidthIndent|56|2}} >
index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''
<div {{BoxWidthIndent|56|2}} >
preset = want_presets ? [[AviSource]]("c:\presets\any.avi") : NOP
...
loadlib ? [[Import]]("my_useful_functions.avs") : NOP
</div>

{{ScriptFunctionH5|Undefined|v2.60|Undefined()}}
: Returns the undefined state.

: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.
: Return value: Actual MemoryMax value set.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetMemoryMax(128)
</div>

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have
... # advanced memory alignment.
</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

{{ScriptFunctionH5|OPT_dwChannelMask|v2.60|global OPT_dwChannelMask(int v)}}

: This group of functions return the absolute difference of pixel value between the current and next frame of {{FuncArg|clip}} – either the combined RGB difference or the Luma, U-chroma or V-chroma differences, respectively. In v2.61 an {{FuncArg|offset}} argument is added, which enables you to access the difference between the RGB, luma or chroma plane of the current frame and of ''any'' other frame. Note that for example clip.'''RGBDifferenceToNext'''(-1) = clip.'''RGBDifferenceToPrevious''', and clip.'''RGBDifferenceToNext'''(0) = 0.

''Examples:''
<div {{BoxWidthIndent|56|2}} >

: This group of functions return statistics about the distribution of pixel values on a plane (Luma, U-chroma and V-chroma, respectively). The statistics are, in order of presentation: maximum, minimum, median and range (maximum - minimum difference).
: {{FuncArg|threshold}} is a percentage, stating how many percent of the pixels are allowed above or below minimum. The threshold is optional and defaults to 0. In v2.61 an {{FuncArg|offset}} argument is added, which enables you to access the statistics of other frames than the current one.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# median and average are close only on even distributions;
# this can be a useful diagnostic
have_intense_brights = YPlaneMedian() - AverageLuma() < threshold
...

Raffriff42: AutoOverlay - fix link

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====
A large list of filters can be downloaded from the following sites but be aware that some plugins listed '''may be outdated''', only recommended as a backup.

====64-bit filters====
'''[[AviSynth%2B_x64_plugins|Comprehensive list of AviSynth+ 64-bit filters]] →'''

====Outdated AviSynth plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

| ColorMatrix
| ColorMatrix corrects the colors of MPEG-2 streams. More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

Raffriff42: /* As Yet Unclassified */ add AutoOverlay

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====
A large list of filters can be downloaded from the following sites but be aware that some plugins listed '''may be outdated''', only recommended as a backup.

*[http://web.archive.org/web/20130803185015/http://www.64k.it/andres/dettaglio.php?sez=avisynth Andres' Filter Collection]

====64-bit filters====
'''[[AviSynth%2B_x64_plugins|Comprehensive list of AviSynth+ 64-bit filters]] →'''

====Outdated AviSynth plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

* High quality adaptative field matching for hard telecine
* Bob, remove the blends and decimate back to the desired framerate for DHT/field-blended
* Creating a VFR clip for hybrid sources
* Bob the interlaced credits, blend-deinterlacing the background while doing minimal damage on the progressive credits, convert their framerate to match the episode's and splice them with it OR leave them @ 30p to create a VFR clip
* Very good combing removal and anti-aliasing functions

|SegmentDisplayOCR is a seven-segment display recognition filter for AviSynth. It has built in logging functionality (it will log frame recognition results) and also can be used in AviSynth conditional filters. The main purpose of this filter is to process readings of various digital instruments (e.g. digital multimeters) captured on video. So if your favourite instrument lacks interface for connecting it to PC you can capture it's readings on cam and convert them to computer readable format with SegmentDisplayOCR filter.

}}

=== Requirements ===
* AviSynth 2.6 or higher, AviSynth+. The latest x64 build is recommended (see ''releases'' above)
* AvsFilterNet plugin [https://github.com/mysteryx93/AvsFilterNet/ https://github.com/mysteryx93/AvsFilterNet/] (included, previous versions do not work correctly)
* .NET framework 4.0 or higher

=== Installation ===
* Copy x86 and/or x64 versions of AvsFilterNet to the plugins folder.
* Copy AutoOverlay_netautoload.dll to the plugin folder, the same file used for both x86 and x64.

=== Description ===
The plugin is designed for auto-aligned optimal overlay of one video clip onto another. The auto-align within [[#OverlayEngine|OverlayEngine]] is performed by testing different coordinates (X and Y of the top left corner), resolutions, aspect ratio and rotation angles of the overlay frame in order to find the best combination of these parameters. The function of comparing the areas of two frames is the root-mean-square error (RMSE) on which PSNR is based - but is inversely proportional. The result of this function within the plugin is called simply DIFF since during development other functions were tested, too. The aim of auto-align is to minimize diff value.

To increase performance, auto-align is divided into several stages of scaling and tests of different [[#OverlayConfig|OverlayConfig]]s which particularly include ranges of acceptable align values. For every OverlayConfig on the first stage, all possible combinations are tested in low resolution. On the next, a comparison based on the best align settings from the previous stage. Finally, if the required accuracy is achieved with current OverlayConfig, the remaining are not tested. After auto-align it is possible to overlay one frame onto another in different ways with configurable ''OverlayRender''.

=== Load plugin in script ===
LoadPlugin("%plugin folder%\AvsFilterNet.dll")
LoadNetPlugin("%plugin folder %\AutoOverlay_netautoload.dll")

[[AviSynth+]] supports plugin auto loading, if .NET plugin filename includes suffix _netautoload. So it includes by default. Check the proper filename in LoadNetPlugin clause.

== Filters ==

=== OverlayConfig ===
{{Template:FuncDef|OverlayConfig(float minOverlayArea, float minSourceArea, float aspectRatio1, float aspectRatio2,<br>
      float angle1, float angle2, int minSampleArea, int requiredSampleArea, float maxSampleDifference,<br>
      int subpixel, float scaleBase, int branches, float acceptableDiff, int correction,<br>
      int minX, int maxX, int minY, int maxY, int minArea, int maxArea, bool fixedAspectRatio, bool debug)}}

This filter describes configuration for [[#OverlayEngine|OverlayEngine]]: how to search optimal align settings. It defines the bounds of align values such as coordinates of the top left corner of overlaid image relative source image, width and height of scaled overlaid image and its rotation angle. Configuration contains OverlayEngine settings for auto-align process as well. The filter output is one frame clip that contains given arguments encoded to the image. It is the hack to inject these values to OverlayEngine as independent entity. It is possible to add some clips to config chain with regular splice operator: OverlayConfig(...) + OverlayConfig(...). OverlayEngine then will test each config in given order. As soon as acceptable diff value is reached, it will be returned as best align and other configs will not be processed.

* '''minOverlayArea''' - minimum intersection part of overlay image in percent. By default: max value if overlay image will be completely contain source image (pan&scan). For example, if source clip is 1920x1080 and overlaid one is 1920x800 then value will be 800/1080 = 74%.
* '''minSourceArea''' - minimum intersection part of source image in percent. By default: max value if source image will be completely contain overlay image (pan&scan). For example, if source clip is 1440x1080 and overlaid one is 1920x1080 then value will be 1440/1920 = 75%.
* '''aspectRatio1''' and '''aspectRatio2''' - range of acceptable aspect ratio of overlaid image. By default – overlay clip aspect ratio. Can be specified in any order: <tt>aspectRatio1=2.35, aspectRatio2=2.45</tt> is the same as <tt>aspectRatio1=2.45, aspectRatio2=2.35</tt>.
* '''angle1''' и '''angle2''' (default 0) - range of acceptable rotation angle if overlaid image. Can be specified in any order. Negative values – clockwise rotation, positive – counter.
* '''minSampleArea''' (default 1000) – minimum area in pixels of downsized source clip at first scale stage. The smaller, the faster, but also the greater risk of getting an incorrect result. Recommended range: 500-3000.
* '''requiredSampleArea''' (default 1000) - maximum area in pixels of downscaled source clip at first scale stage. The smaller, the faster, but also the greater risk of getting an incorrect result. Recommended range: 1000-5000.
* '''maxSampleDifference''' (default 5) – max allowed DIFF between downscaled source clip at previous and current scale iteration. If it is too high then previous iteration will not be processed.
* '''subpixel''' (default 0) – subpixel align accuracy. 0 – one pixel accuracy, 1 – half pixel, 2 – quarter and so on. Zero is recommended if one clip is much smaller then another. 1-3 if both clips have about the same resolution.
* '''scaleBase''' (default 1.5) – base to calculate downscale coefficient by formula <tt>coef=scaleBase^(1 - (maxStep - currentStep))</tt>.
* '''branches''' (default 1) - how many best align params from previous scale stage will be analyzed at the next one. 1-10 is recommended. The higher - the longer.
* '''acceptableDiff''' (default 5) – acceptable DIFF value. If it will be achieved with current OverlayConfig the remaining configs in the chain will not be processed.
* '''correction''' (default 1) – the value of correction the best align params between scale stages. The higher, then more different align params are tested.
* '''minX''', '''maxX''', '''minY''', '''maxY''' - ranges of top left corner coordinates, unlimited by default.
* '''minArea''', '''maxArea''' - area range of overlaid image in pixels, unlimited by default.
* '''fixedAspectRatio''' (default false) - maximum accurate aspect ratio. May be true only if aspectRatio1=aspectRatio2.
* '''debug''' (default false) – output given arguments, slower.

=== OverlayEngine ===
{{Template:FuncDef|OverlayEngine(clip, clip, string statFile, int backwardFrames, int forwardFrames, clip sourceMask,<br>
      clip overlayMask, float maxDiff, float maxDiffIncrease, float maxDeviation, bool stabilize,<br>
      clip configs, string downsize, string upsize, string rotate, bool editor, string mode, bool debug)}}

Filter takes two clips: source and overlay. It performs auto-align by resizing, rotation and shifting an overlay clip to find the best diff value. Best align settings are encoded into output frame so it could be read by another filter. The sequence of these align settings frame-by-frame (statistics) could be written to in-memory cache or file for reuse and manual editing via built-in visual editor.

* '''source''' - first, base clip.
* '''overlay''' - second, overlaid clip. Both clips must be in the same color space without chroma subsampling. Y8, YV24 and RGB24 are supported.
* '''statFile''' (default empty) – path to the file with current align values. If empty then in-memory cache is used. Recommended use-case: to test different OverlayConfigs use in-memory cache. After that set statFile and run analysis pass.
* '''backwardFrames''' and '''forwardFrames''' (default 3) – count of previous and forward frames for searching align params of current frame.
* '''sourceMask''', '''overlayMask''' (default empty) – mask clips for source and overlaid clips. If mask was specified then pixels that correspond to zero values in mask will be excluded from comparison function. In RGB color space all channels are analyzed independent. In YUV only luma channel is analyzed. Masks and clips should be in the same type color space (YUV or RGB24). Note that in planar color space masks should be in full range (<tt>ColorYUV(levels="TV->PC")</tt>).
* '''maxDiff''' (default 5) – diff value below which auto-align is marked as correct.
* '''maxDiffIncrease''' (default 1) – maximum allowed diff increasing in the frame sequence.
* '''maxDeviation''' (default 0.5) – max allowed rest area of clip in percent subtracting intersection to detect scene change.
* '''stabilize''' (default true) – attempt to stabilize align values at the beginning of scene when there is no enough backward frames including to current scene.
* '''configs''' (default OverlayConfig with default values) – configuration list in the form of clip. Example: <tt>configs=OverlayConfig(subpixel=1, acceptableDiff=10) + OverlayConfig(angle1=-1, angle2=1)</tt>. If during analyses of first configuration it founds align values with diff below 10 then second one with high ranges and low performance will be skipped.
* '''downsize''' and '''upsize''' (default ''BilinearResize'') – functions that used for downsizing and upsizing of overlaid clip during auto-align.
* '''rotate''' (default ''BilinearRotate'') – rotation function. Currently built-in one is used which based on AForge.NET.
* '''editor''' (default false). If true then visual editor form will be open at the script loading.
* '''mode''' (default "default") – engine mode: DEFAULT – default modeUPDATE – as default but with forced diff updateERASE – erase statisticsREADONLY – use only existing align statistics
* '''debug''' (default false) - output align values, slower.

The engine works out optimal align values: coordinates of overlaid clip's top left corner (x=0,y=0 is the left top corner of source clip), rotation angle in degrees, overlaid width and height, floating-point crop values from 0 to 1 for subpixel accuracy (left, top, right, bottom) and DIFF value. ''[[#OverlayConfig|OverlayConfig]]'' chain provides ranges of acceptable align values. The engine runs each config one-by-one while align values with acceptable diff would not be found. Auto-align process for each configuration includes multiple scaling stages. At the first stage all possible combinations of align values are tested in the lowest resolution. The count of best align value sets passed to the next stage is given by <tt>OverlayConfig.branches</tt> parameter. At the next stages best sets from previous are corrected. Note that, simplified, one pixel in low resolution includes four from high. ''OverlayConfig'' contains <tt>correction</tt> parameter to set correction limit for all directions and sizes in pixels.Image resizing is performed by functions from ''downsize'' and ''upsize'' parameters. First one is commonly used at the intermediate scale stages, last one at the final. So it's recommended to use something better than BilinearResize at the end. The functions must have signature as follow: <tt>Resize(clip clip, int target_width, int target_height, float src_left, float src_top, float src_width, float src_height)</tt>. Additional parameters are allowed, that is, the signature corresponds to standard resize functions. It is recommended to use the ResampleMT plugin, which provides the same functions but internally multithreaded.Besides auto-align of given frame the engine analyses sequence of neighboring frames is specified by ''backwardFrames'' and ''forwardFrames'' parameters according to ''maxDiff, maxDiffIncrease, maxDeviation, stabilize'' params as described below:

* Request align values of current frame.
* Return data from statFile or in-memory cache if this frame was auto-aligned already.
* If previous frames in quantity of ''backwardFrames'' are already aligned with the same values and their DIFF don't exceed ''maxDiff'' value, then the same align values will be tested for the current frame.
* If maximum DIFF is increasing within sequence is lower than ''maxDiffIncrease'', then the engine analyzes next frames in quantity of ''forwardFrames'' otherwise current frame will be marked as independent from previous – that means scene change.
* If current frame was included to the sequence with previous frames then the same align values will be tested on forward frames if ''forwardFrames'' is greater than zero. If all next frames are good at the same align then current frame will be included to the sequence.
* If some of next frames exceed ''maxDiff'' value or difference between next frame diff and average diff is higher than ''maxDiffIncrease'' then the engine will work out optimal auto-align values for next frame. If new align values significantly differ from previous then we have scene change otherwise there is pan&scan episode and each frame should be processed independently. The parameter that used for this decision is ''maxDeviation''.
* If current frame is marked as independent after previous operations and ''OverlayEngine.stablize=true'' then engine tries to find equal align params for the next frames too to start new scene.
* If ''backwardFrames'' is equal to zero then each frame is independent. This scenario has very low performance and may cause image shaking. Use this only if you have two different original master copies from which the sources were made.

==== Visual editor ====
Displayed when ''OverlayEngine.editor''<nowiki>=true. It is useful after analysis pass when statFile is specified to check all scenes and manually correct incorrect aligned frames.</nowiki>Preview from the left side. Below there is trackbar by total frame count and current frame input field. Grid with equal aligned frame sequences on the right. It is possible to move between scenes by row selection. Below grid there is a control panel.''Overlay settings'' contains controls to change align values of current scene. ''Crop'' fields in pro mil px from 0 to 1000.Below there is ''AutoOverlay'' section.''Single frame'' button performs auto-align based on the current frame. The result is applied to the full scene. ''Separated frame'' button performs auto-align based on the current frame. If new align values is differ from the scene then current frame is separated. ''Scene'' button performs auto-align for each frame in the scene independently.On the right there are controls to process pan&scan scenes. Before using it join pan&scan frame sequence into one scene (one row in grid) and press ''Single frame'' for the first frame in the sequence. After that set maximum ''distance'' in pixels of shifting and resizing limit in pro mil for each next frame according to previous one. The click to ''Pan&scan'' button to process the whole scene. The progress will be displayed at the form caption. Below there is ''Display settings''. It includes the same settings as OverlayRender filter: output resolution, overlay mode, gradient and noise length, opacity in percent, ''preview'' and ''display info'' checkboxes. If preview is disabled then source clip is displayed.At the bottom of control panel there are button panel. The scenes that were changed by user are highlighted with yellow color in grid. ''Save'' button will apply changes to statFile. ''Reset'' will reload all data from file. ''Reload'' will reload data only for current frame and apply it to while scene. ''Separate'' will exclude the current frame from scene. ''Join prev'' will join previous scene to current and overwrite align values. ''Join next'' will join next scene to current and overwrite align values. ''Join to'' will join current scene to specified frame and overwrite align values.

'''Hotkeys''':

* Ctrl + S - save
* Ctrl + R - reload
* D - enable/disable difference
* P - enable/disable preview
* Ctrl + arrow keys - move overlay image
* Ctrl + add/subtract - scale overlay image
* A, Z - next/previous frame

=== OverlayRender ===
{{Template:FuncDef|OverlayRender(clip, clip, clip, clip sourceMask, clip overlayMask, bool lumaOnly, int width, int height, <br>
      int gradient, int noise, bool dynamicNoise, bool mode, float opacity, int colorAdjust,<br>
      string matrix, string upsize, string downsize, string rotate, bool debug)}}

This filter preforms rendering of the result clip using align values from the engine.

* '''engine''' - ''OverlayEngine'' clip.
* '''source''' - first, base clip.
* '''overlay''' - second, overlaid clip. Both clips must be in the same color space without chroma subsampling. Y8, YV24 and RGB24 are supported.
* '''sourceMask''', '''overlayMask''' (default empty) - mask clips for source and overlaid clips. Unlike masks in overlay engine in this filter they work as avisynth built-in overlay filter masks. If both masks are specified then they are joined to one according align values. The purpose of the masks is maximum hiding of logos and other unwanted parts of the clips at transparent or gradient parts, which could be specified by ''gradient'' and ''noise'' parameters.
* '''lumaOnly''' (default false) – overlay only luma channel when ''mode''<nowiki>=1. </nowiki>
* '''width''' и '''height''' - output width and height. By default are taken from source clip.
* '''gradient''' (default 0) – length of gradient at the overlay mask to make borders between images smoother. Useful when clips are scientifically differ in colors or align is not very good.
* '''noise''' (default 0) - length of “noise gradient” at the overlay mask to make borders between images smoother. Useful when clips are in the same color and align is very good.
* '''dynamicNoise''' (default true) – use dynamic noise gradient if ''noise'' > 0.
* '''mode''' (default 1) – overlay and cropping mode:1 - crop around the edges of the source image.2 - combination of both images with cropping to the all four edges of the output clip with “ambilight” at the corners.3 - combination of both images without any cropping.4 - as 3 but with “ambilight” at the corners.5 - as 3 but with “ambilight” at all free space.6 – as 3 but with pure white clips. Useful to combine the result clip with another one.7 - as 1 but clips overlaid in difference mode. Useful to check align.
* '''opacity''' (default 1) – opacity of overlaid image from 0 to 1.
* '''colorAdjust''' (default 0) ''unstable'' - color adjustment mode:0 - disabled1 – overlaid clip will be adjusted to source2 - source clip will be adjusted to overlaidColor adjustment performs by histogram matching in the intersection area. For the YUV images adjusts only luma channel. For the RGB images adjusts all 3 channels independently.
* '''matrix''' (default empty). If specified YUV image converts to RGB with given matrix for color adjustment.
* '''downsize''' и '''upsize''' (default ''BilinearResize'') - downsize and upsize functions. It’s recommended to use functions with high quality interpolation.
* '''rotate''' (default ''BilinearRotate'') – rotation function.
* '''debug''' - output align settings to the top left corner.

====Outdated AviSynth plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

| ColorMatrix corrects the colors of MPEG-2 streams. More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod. See [http://forum.doom9.org/showthread.php?t=82217 discussion].

BlankClip

2018-02-11T03:38:43Z

Raffriff42: correction

<div style="max-width:62em" >
'''BlankClip''' produces a solid color video clip with silent audio. The ''clip'' passed as an argument is used as a ''template'' - for frame rate, image size, and so on, but the template is optional. You can specify as many clip properties explicitly as you wish. By default, '''BlankClip''' will produce a pitch-black 10 second clip; 24 fps, 640x480, RGB32, with 16 bit, 44100 Hz, mono, silent audio.

When supplying a template, '''BlankClip''' returns a clip with [[Clip_properties|properties]] copied from that template. If the template is audio-only, you get a blank audio-only clip, and if it's video-only you get a blank video-only clip. If you start to add parameters that force a video track (i.e. {{FuncArg|width}}, {{FuncArg|height}} or {{FuncArg|pixel_type}}) or audio track (i.e. {{FuncArg|audio_rate}}, {{FuncArg|channels}} or {{FuncArg|sample_type}}), the remaining parameters for that track will be the defaults. (AviSynth v2.60)

'''Blackness''' is an ''alias'' for '''BlankClip'''. The parameters are the same.

BlankClip

2018-02-06T00:31:36Z

Raffriff42: notes - 'clip' arg; 'audio_rate'=0 kills audio

<div style="max-width:62em" >
'''BlankClip''' produces a solid color video clip with silent audio. The ''clip'' passed as an argument is used as a ''template'' - for frame rate, image size, and so on, but the template is optional. You can specify as many clip properties explicitly as you wish. By default, '''BlankClip''' will produce a pitch-black 10 second clip; 24 fps, 640x480, RGB32, with 16 bit, 44100 Hz, mono, silent audio.

When supplying a template, '''BlankClip''' returns a clip with [[Clip_properties|properties]] copied from that template. If the template is audio-only, you get a blank audio-only clip, and if it's video-only you get a blank video-only clip. If you start to add parameters that force a video track (i.e. {{FuncArg|width}}, {{FuncArg|height}} or {{FuncArg|pixel_type}}) or audio track (i.e. {{FuncArg|audio_rate}}, {{FuncArg|channels}} or {{FuncArg|sample_type}}), the remaining parameters for that track will be the defaults. (AviSynth v2.60)

'''Blackness''' is an ''alias'' for '''BlankClip'''. The parameters are the same.

{{ScriptFunctionH5|Import||Import(filename)}}
: Evaluates the contents of another script and returns the result of that evaluation. '''It works exactly like [[#Eval|Eval]] above''', except
:* The expression to be evaluated comes from a file instead of a string;
:* The [[#Script_functions|values of]] ''ScriptName'', ''ScriptFile'' and ''ScriptDir'' are set to the current (imported) script;
:* The current working directory ([[wikipedia:Working_directory|CWD]]) is [[Internal_functions#SetWorkingDir|set]] to the current (imported) script.

:[[Script_functions|Functions]], [[Script_variables|variables]] and loaded plugins declared inside the imported script are made available to the parent script. <b>Import</b>'s return value can be assigned to a variable of the parent script; this is most useful when the imported script ends with a clip.

: Typically '''Import''' is used to make library functions available to the parent script, and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. Some indicative uses of '''Import''' include:
:* Storing multiple script-functions, variables and global variables for reuse by scripts (creation of script libraries).
:* Retrieving pre-built streams.
:* Retrieving dynamically configured pre-built streams (the core idea is that the importing script declares some global variables which the imported script uses to configure the stream that will return).
:'''Note 1''': Since the contents of the imported script are evaluated at the point of invocation, it is possible by enclosing the '''Import''' call in a nested scope (for example inside a function) to make available to the importing script the functions and globals of the imported script ''without'' its script-level variables.
:'''Note 2''': Any script with the [[AVSI]] extension in the AviSynth Plugins folder is automatically imported. This is useful for making script functions available to any new script you create without having to copy and paste.
''Examples:''
<div {{BoxWidthIndent|56|2}} >

: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''

: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

{{HiddenAnchor|AviSynth.2B.27s_Plugin_Autoloader}}
===Plugin Autoloader===
*'''1st October 2013''' | Source: [http://forum.doom9.org/showthread.php?p=1646304#post1646304 here] and subsequent post.
Okay, so how do multiple plugin directories interact with plugin autoloading?

As a recap, here is how it used to work in the official Avisynth:
:* Look for the string HKEY_CURRENT_USER/Software/Avisynth/PluginDir2_5 in the registry. If it exists, load plugins from the path specified there and stop.
:* If the above string didn't exist, look in HKEY_LOCAL_MACHINE/Software/AviSynth/PluginDir2_5. Try to load plugins from the path specified there.
:* Done.

First thing to note, is that classic AviSynth only ever searches for plugins in one single directory. It only knows two directories (both specified in the registry), and it only tries the second path if there is no entry for the first one.

AviSynth+'s autoloader has a list of autoload directories. It iterates over all those directories and tries to load all plugins from each. But (and a big but!) it will not load a plugin from a directory if another plugin with the same basename is already loaded. The basename of a plugin is simply its file name without the extension.

The expected use case is that you can now overlay a new plugin directory on top of another one. AviSynth+ then would load all plugins from the first folder, then load only those plugins from the second that weren't loaded from the first, then those from the third that weren't loaded from the first or second and so on. For example, let's say your usual plugin folder has a lot of plugins you normally use. But at one time you have a small number of updated plugins that you only want to use from a few scripts, but you do not yet want to replace your existing plugins globally. Then you'd just add a new plugin overlay folder, with only the new plugins in it, and that's it. All scripts that specify the new folder will autoload all plugins from your usual one, except for the new plugins, which would get loaded from the new folder. All your other scripts will still use your old plugins.

By default, AviSynth+'s autoload folder list has four paths in it, in this order:
# PluginDir+ in Software/Avisynth in HKEY_CURRENT_USER
# PluginDir+ in Software/Avisynth in HKEY_LOCAL_MACHINE
# PluginDir2_5 in Software/Avisynth in HKEY_CURRENT_USER
# PluginDir2_5 in Software/Avisynth in HKEY_LOCAL_MACHINE

This means, if there are ever plugins which will only work with AviSynth+ but not with classic AviSynth, you can put them into one of the "PluginDir+" folders. AviSynth+ will then use the classic plugins from the normal AviSynth, but if there are versions of some plugins written for AviSynth+, it will use them instead, and the classic avisynth.dll will still not be bothered with them. This is all without you having to lift a finger (except for adding the "PluginDir+" values to the registry once, until we have an installer). So to summarize all this, you have the ability to define a plugin autoload folder in the registry which will only be used by AviSynth+, but not by AviSynth, in addition to your classic plugins.

====New Functions====
However, another new functionality offered by AviSynth+, is that now you can also specify autoload paths in the scripts. There are two functions for this:

*<code> AddAutoloadDir(string path, bool toFront)</code>: this will add a new autoload folder. The string parameter is obligatory, it is the folder path where to load from. The second boolean parameter is optional, and if true (default), it will add the path to the front/beginning of the autoloader's list, which means it will be searched earlier than the rest. If it is false, the path will get added to the end of the list, so it will get searched last (unless you again add another one to the end).
*<code> ClearAutoloadDirs()</code>: This will clear all the paths from the autoloader's list. Note that it is NOT a reset to the default state. ClearAutoloadDirs() will clear all folders, so if you don't add new ones after that, you have disabled the autoload functionality. This is, BTW, also a way to disable autoloading for a particular script in AviSynth+.

'''Here's an important note''': You can only call these functions if no plugin has been autoloaded yet. Autoloading happens if the first unknown function is looked up. This means you can only call <code>AddAutoloadDir</code> or <code>ClearAutoloadDirs</code> if you have only made calls to built-in functions up to that point in the script. I suggest you start your scripts with these calls to avoid any problems.

There is only one thing left to discuss: Are there any special directories you can reference from your script? You bet there are:
* <tt>SCRIPTDIR</tt> is the folder of the most current script. It is the path of the imported script if your script calls import()
* <tt>MAINSCRIPTDIR</tt> is the folder of your main script, the one where execution started
* <tt>PROGRAMDIR</tt> is the folder of the executable running the current script
* <tt>USER_PLUS_PLUGINS</tt> is the string stored in PluginDir+ in Software/Avisynth in HKEY_CURRENT_USER
* <tt>MACHINE_PLUS_PLUGINS</tt> is the string stored in PluginDir+ in Software/Avisynth in HKEY_LOCAL_MACHINE
* <tt>USER_CLASSIC_PLUGINS</tt> is the string stored in PluginDir2_5 in Software/Avisynth in HKEY_CURRENT_USER
* <tt>MACHINE_CLASSIC_PLUGINS</tt> is the string stored in PluginDir2_5 in Software/Avisynth in HKEY_LOCAL_MACHINE
... all these special constants are '''case-sensitive''' for now.

====Examples====
* If you want plugins to be autoloaded from the script's "autoload" directory too, you'd write:
<code>AddAutoloadDir("MAINSCRIPTDIR/autoload")</code>

* If you want plugins to be autoloaded from the script's "autoload" directory, only from there and nowhere else, you'd write:
<code>ClearAutoloadDirs()<br>
AddAutoloadDir("MAINSCRIPTDIR/autoload")</code>

* If you wanted to manually recreate the default state of the autoloading folder list, you'd write:
<code>ClearAutoloadDirs()<br>
AddAutoloadDir("USER_PLUS_PLUGINS", false)<br>
AddAutoloadDir("MACHINE_PLUS_PLUGINS", false)<br>
AddAutoloadDir("USER_CLASSIC_PLUGINS", false)<br>
AddAutoloadDir("MACHINE_CLASSIC_PLUGINS", false)</code>

====Notes====
*Both AviSynth and AviSynth+ already query interface versions. They try to load the 2.6 interface from a plugin first, and if that is not supported, they try to load the 2.5 interface. AviSynth+ also tries to load the C interface if both of the previous ones fail. In the future, the C interface should probably be prioritized over 2.5.
*In what contexts do <tt>MAINSCRIPTDIR</tt> and the other 'special' names get replaced with the corresponding folders? In all strings, or only when used in the argument to AddAutoloadDir?<br>-- Only in <code>AddAutoloadDir()</code>, and even there, only if they are at the very beginning of the string. These get replaced to absolute folder paths, so if they are not at the beginning of the string, replacing them would only result in an invalid path (e.g. you'd end up with "c:" in the middle of your path).
*[http://forum.doom9.org/showthread.php?p=1646392#post1646392 Source]
*AviSynth+ autoloads plugins if any of the following happens:[http://forum.doom9.org/showthread.php?p=1662402#post1662402]
**AutoloadPlugins() is called
**LoadPlugin() is called
**A yet unknown (non-internal) function is called
*avs_function_exists does not find the external source filter in this case because none of the above happened. So MasterNobody's patch is the right thing to do.

===GScript===
GScript (''a plugin for AviSynth that provides new control-flow constructs such as loops'') has been incorporated natively into AviSynth+. Syntax is mostly unchanged, with two notable differences:

*In AviSynth+ there is no need to wrap your GScript code in a string. The language extensions are native to AviSynth+ and can be used transparently.
*The "return" statement has been changed to not only exit the GScript code block, but behaves like a normal AviSynth [[Grammar#Statements.2C_Expressions.2C_Types_and_Operators|return statement]]: it causes the termination of the active script block ([[User_functions|user function]]), or if not in a function, the entire script.

===Logging Facility===
Starting with r2069, AviSynth+ received a logging facility. You can enable it using <code>SetLogParams(string target, int "level")</code> at the beginning of your script.

* <code>'target'</code> can be either <code>"stderr"</code>, <code>"stdout"</code>, or a path to a file.

* <code>'level'</code> is 1: LOG_ERROR / 2 : LOG_WARNING / 3 : LOG_INFO/ 4 : LOG_DEBUG, with increasing verbosity. By default, logging is disabled (0).

Log messages can be output by scripts using <code>LogMsg(string msg, int "level")</code>.

If logging is enabled, AviSynth+ will output log messages by itself too. It will automatically log errors, and will issue warnings and notes to the user to inform him about potential problems, buggy plugins, suboptimal settings et cetera. There are a couple of these log messages and they come in various colors.

<div style="max-width:62em" >
*Source: [http://forum.doom9.org/showthread.php?p=1666371#post1666371 Doom9 Forum]
So, how to use MT in AviSynth+? Most of it has been posted earlier actually, but let me summarize it.

By default, your script will run in single-threaded mode, just like with SEt's build. Also, just like in SEt's build, you'll have to make sure that filters use the correct MT mode, or else they might wreak havoc. There are three basic MT modes (1,2,3) and an experimental workaround mode (4) since r2440, and modes 1-3 are the same modes as in (yeah you guessed correctly) SEt's build. Which means you can use the same modes that you have used with AviSynth-MT.

There are some things though that are different and/or new in AviSynth+. The first difference is *how* you set the MT mode. In AviSynth-MT, you had to use SetMTMode(X), which caused all filters following that line to use mode X (until the next call to SetMTMode()). This meant if you needed to use multiple MT modes, you had to insert all those calls in the middle of your script, littered over many places.

===Setting MT modes===
AviSynth+ does it differently. In AviSynth+, you specify the MT-mode for only specific filters, and those filters will then automatically use their own mode, even if there were other MT-modes inbetween. This means you can specify all the MT modes at the beginning without polluting your script. You can even make a SetMTMode.avsi if you wish and let it autoload for all of your scripts, or import() it from their top. This is much cleaner, and it allows you to maintain all your MT-modes centrally at a single place. To make this distinction clear from AviSynth+, SetMTMode() is called SetFilterMTMode() in AviSynth+.

===Enabling MT===
The other difference is how you actually enable multithreading. Calling SetFilterMTMode() is not enough, it sets the MT mode, but the MT mode only has an effect if MT is enabled at all. Note this means you can safely include/import/autoload your SetFilterMTMode() calls in even single-threaded scripts, and they will not be messed up. Uhm, onto the point: You enable MT by placing a single call to Prefetch(X) at the '''end''' of your script, where X is the number of threads to use. If there is a return statement in your script it must be placed '''after''' Prefetch().

===Example ===
</div><div style="max-width:76em" ><pre>
# This line causes all filters that don't have an MT mode explicitly use mode 2 by default.
# Mode 2 is a relatively safe choice until you don't know most of your calls to be either mode 1 or 3.
# Compared with mode 1, mode 2 trades memory for MT-safety, but only a select few filters will work with mode 1.
SetFilterMTMode("DEFAULT_MT_MODE", 2)
or
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)

# FFVideoSource(), like most of all source filters, needs MT mode 3.
# Note: starting with AviSynth+ r2069, it will now automatically recognize source filters.
# If it sees a source filter which has no MT-mode specified at all, it will automatically use
# mode 3 instead of the default MT mode.
SetFilterMTMode("FFVideoSource", 3)
or
SetFilterMTMode("FFVideoSource", MT_SERIALIZED)

# Now comes your script as usual
FFVideoSource(...)
Trim(...)
QTGMC(...)
...

# Enable MT!
Prefetch(4)
</pre></div>
<div style="max-width:62em" >

===Help filling MT modes===
The following script contains MT modes for various plugins, save it as <tt>mtmodes.avsi</tt> and place in your auto-load folder. The script is a work-in-progess, there's still lots of plugins that need to be tested and validated. When the script is finalized, the only thing the user will have to write in his script is the <code>Prefetch</code> call, all <code>SetFilterMtMode</code> calls will be hidden in a single <tt>.avsi</tt> script.

===Choosing the correct MT mode===
Please do check if the actual output is correct. Fast but corrupted output is useless. Easy way of checking would be using something like <code>[[ColorBars]](1920, 1080, "YV12").[[AddGrainC]](10000, 10000, seed=1)</code> as a source filter. It doesn't always work right but will do for most stuff.[http://forum.doom9.org/showthread.php?p=1667434#post1667434]

Source: http://forum.doom9.org/showthread.php?p=1667439#post1667439

*<code>MT_NICE_FILTER</code>: Some filters (like nnedi3) use some buffers to do their dirty work and with mode 1 you get multiple threads writing data from different frames to the same buffer. This causes corruption when later someone tries to read from this buffer and gets not what was expected. Most of the "more complicated" filters use some kind of temporary storage thus won't work well with this mode. Simple filters might.

*<code>MT_MULTI_INSTANCE</code>: Mode 2 doesn't have this issue because multiple threads will get their own buffers and no data will be shared. Hence mode 2 is the "default" mode which should work with ''most'' filters, but it wastes memory like crazy (take SangNom2 for example - for 1080p YV12 frame, size of temporary buffers is about 10MB, so with 4 threads you get 40MBs on single filter invocation. Now add some usual supersampling to this and multiple invocations in most aa scripts and... you get the idea).

*<code>MT_SERIALIZED</code>: If the filter requires sequential access or uses some global storage, then mode 3 is the only way to go. Source filter (filters without clip parameter) are autodetected, they do not need an explicit MT mode setting, they will automatically use MT_SERIALIZED.

*<code>MT_SPECIAL_MT</code>: Experimental. Now use only for MP_Pipeline, the filter is like a source filter (no input clip parameter), internally multithreaded, and suffer heavy performance degradation from any of the three regular mt modes. Really, this is a workaround. Available from AviSynth+ version r2440.

===Closing notes (don't skip!)===
*Remember that MT is only stable as long as you have specified a correct MT mode for all filters.
*Instead of the numbers 1-2-3-4, you can also use symbolic names for MT modes: MT_NICE_FILTER (1), MT_MULTI_INSTANCE (2), MT_SERIALIZED (3), MT_SPECIAL_MT (4)
*Mode 3 (MT_SERIALIZED) is evil. It is necessary for some filters, and it is usually no problem for source filters, but it can literally completely negate all advantages of MT, if such a filter is placed near the end of your script. Let us know if you meet a non-source mode 3 filter, we might be able to do something about it, but in general, avoid such calls if you want performance. (And of course, insert what you have found into here.)
*The new caches will save you a lot of memory in single-threaded scripts, but due to the way they work, they will also use more memory than before with MT enabled. The memory usage will scale much closer with the number of threads you have. Just something to keep in mind.
*MT-enabled AviSynth+ triggers a latent bug in AvsPmod. Until a new version of AvsPmod is officially released, use [http://forum.doom9.org/showpost.php?p=1801766&postcount=1202 this build]. A thousand thanks to vdcrim for the fix.
*Using too many threads can easily hurt performance a lot, because there are other bottlenecks too in your PC than just the CPU. For example, if you have a quad-core machine with 8 logical cores, less than 8 threads will often work much better than 8 or more.

===Informational links===
Links contain bits and pieces of how MT works in AviSynth+, correct usage, and other things MT.

Raffriff42: "stacked" argument: add example

{{FilterCat|External_filters|Plugin_functions|Source_filters}}
This function uses [http://en.wikipedia.org/wiki/Libav#Video_codecs libavcodec] as a video decoder and libavformat as a demuxer.
<br>
<br>
== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|LWLibavVideoSource (string source, int "stream_index", int "threads", bool "cache", int "seek_mode", int "seek_threshold", bool "dr", int "fpsnum", int "fpsden", bool "repeat", int "dominance", bool "stacked", string "format", string "decoder")}}
<br>
::{{Par2|source|string| }}
:::The path of the source file; path can be omitted if the source file is in the same directory as the AviSynth script (*.avs).
<br>
::{{Par2|stream_index|int|-1}}
:::The stream index to open in the source file. The value -1 means trying to get the video stream which has the largest resolution.
<br>
::{{Par2|threads|int|0}}
:::The number of threads to decode a stream by libavcodec.
:::The value 0 means the number of threads is determined automatically and then the maximum value will be up to 16.
<br>
::{{Par2|cache|bool|true}}
:::Create the index file (.lwi) to the same directory as the source file if set to true.
:::The index file avoids parsing all frames in the source file at the next or later access.
:::Parsing all frames is very important for frame accurate seek.
<br>
::{{Par2|seek_mode|int|0}}
:::How to process when any error occurs during decoding a video frame.
::::*0 : Normal
:::::This mode retries sequential decoding from the next closest RAP up to 3 cycles when any decoding error occurs.
:::::If all 3 trial failed, retry sequential decoding from the last RAP by ignoring trivial errors.
:::::Still error occurs, then return the last returned frame.
::::*1 : Unsafe
:::::This mode retries sequential decoding from the next closest RAP up to 3 cycles when any fatal decoding error occurs.
:::::If all 3 trial failed, then return the last returned frame.
::::*2 : Aggressive
:::::This mode returns the last returned frame when any fatal decoding error occurs.
<br>
::: * RAP is an abbreviation of random accessible point.
<br>
::{{Par2|seek_threshold|int|10}}
:::The threshold to decide whether a decoding starts from the closest RAP to get the requested video frame or doesn't.
::::Let's say
:::::the threshold is T,
::::and
:::::you request to seek the M-th frame called f(M) from the N-th frame called f(N).
::::If M > N and M - N <= T, then
:::::the decoder tries to get f(M) by decoding frames from f(N) sequentially.
::::If M < N or M - N > T, then
:::::check the closest RAP at the first.
:::::After the check, if the closest RAP is identical with the last RAP, do the same as the case M > N and M - N <= T.
:::::Otherwise, the decoder tries to get f(M) by decoding frames from the frame which is the closest RAP sequentially.
<br>
::: * RAP is an abbreviation of random accessible point.
<br>
::{{Par2|dr|bool|false}}
:::Try direct rendering from the video decoder if set to true.
:::The output resolution will be aligned to be mod16-width and mod32-height by assuming two vertical 16x16 macroblock.
:::For H.264 streams, in addition, 2 lines could be added because of the optimized chroma MC.
<br>
::{{Par2|fpsnum|int|0}}
:::Forced frame rate numerator.
:::If frame rate is set to a positive value, output frame rate is forced to the specified value by padding and/or dropping frames.
:::Otherwise, output frame rate is set to a computed average frame rate and the output process is performed by actual frame-by-frame.
<br>
::{{Par2|fpsden|int|1}}
:::Forced frame rate denominator.
:::See 'fpsnum' in details.
<br>
::{{Par2|repeat|bool|false}}
:::Reconstruct frames by the flags specified in video stream and then treat all frames as interlaced if set to true and usable.
<br>
::{{Par2|dominance|int|0}}
:::Which field, top or bottom, is displayed first.
::::*0 : Obey source flags
::::*1 : TFF i.e. Top -> Bottom
::::*2 : BFF i.e. Bottom -> Top
:::This option is enabled only if one or more of the following conditions is true.
::::- 'repeat' is set to true.
::::- There is a video frame consisting of two separated field coded pictures
<br>
::{{Par2|stacked|bool|false}}
:::Use the stacked format for a hack of AviSynth high bit-depth support if set to true.
:::Note: direct rendering is not available at all if stacked format is used.

Raffriff42: tweak table

<div style="max-width:62em" >
Adjusts brightness, contrast, and gamma. This is done using the following ''transfer function'':
:''output'' = ( (''input'' - {{FuncArg|input_low}}) / ({{FuncArg|input_high}} - {{FuncArg|input_low}}) )<sup>(1 / {{FuncArg|gamma}})</sup> * ({{FuncArg|output_high}} - {{FuncArg|output_low}}) + {{FuncArg|output_low}}

*{{FuncArg|input_low}} and {{FuncArg|input_high}} determine what ''input'' pixel values are treated as pure black and pure white.
*{{FuncArg|output_low}} and {{FuncArg|output_high}} determine what ''output'' values are treated as pure black and pure white.
*{{FuncArg|gamma}} controls the degree of non-linearity in the conversion.

This is one of those filters for which it would really be nice to have a GUI. Since we can't offer a GUI (though [http://forum.doom9.org/showthread.php?t=153248 AvsP] does), we at least make this filter '''compatible''' with [[VirtualDub|VirtualDub's]] when the clip is [[RGB]]. In that case you should be able to take the numbers from VirtualDub's ''Levels'' dialog and pass them as parameters to the '''Levels''' filter and get the same results. Unlike VirtualDub's filter however, the input and output parameters can be larger than 255{{D}}.

When processing data in [[YUV]] mode, '''Levels''' only gamma-corrects the luma information, not the chroma. Gamma correction is really an RGB concept, and is only approximated here in YUV. If ''{{FuncArg|gamma}}=1.0'' (unity), the filter should have the same effect in both RGB and YUV modes. For adjusting brightness or contrast in YUV mode, it ''may'' be better (depending on the effect you are looking for) to use [[Tweak]] or [[ColorYUV]], because '''Levels''' changes the chroma of the clip.

Note in {{AvsPluscon}}, the parameters {{FuncArg|input_low}}, {{FuncArg|input_high}}, {{FuncArg|output_low}} and {{FuncArg|output_high}}
* are <tt>float</tt> instead of <tt>int</tt>.
* are not [[Autoscale_parameter|autoscaling]] – they are relative to the current bit depth:

==== Syntax and Parameters ====
{{FuncDef|Levels(clip ''input'', <br>
      int ''input_low'', float ''gamma'', int ''input_high'', int ''output_low'', int ''output_high''<br>
      [, bool ''coring'' , bool ''dither'' ] )}}<br>
{{FuncDef|Levels(clip ''input'', <br>
      float ''input_low'', float ''gamma'', float ''input_high'', float ''output_low'', float ''output_high''<br>
      [, bool ''coring'' , bool ''dither'' ] )}} {{AvsPluscon}}

:{{Par2|clip|clip|(required)}}
::Source video.

:{{Par2|input_low|int/float*|(required)}}
::Input values at {{FuncArg|input_low}} or lower are treated as ''black'', and lighter colors are darkened proportionally.
::Therefore raising {{FuncArg|input_low}} darkens the output.
:: <big>*</big> = <tt>int</tt> in AviSynth, <tt>float</tt> in AviSynth+

:{{Par2|gamma|float|(required)}}
::[[Wikipedia:Gamma_correction|Gamma]] adjustment. See [[#Examples|examples]].
::Higher {{FuncArg|gamma}} brightens the output; lower {{FuncArg|gamma}} darkens the output.

:{{Par2|input_high|int/float|(required)}}
::Input values at {{FuncArg|input_high}} or higher are treated as ''white'', and darker colors are brightened proportionally.
::Therefore lowering {{FuncArg|input_high}} brightens the output.

:{{Par2|output_low|int/float|(required)}}
::Dark values brighten to gray as {{FuncArg|output_low}} becomes larger.

:{{Par2|output_high|int/float|(required)}}
::Light values darken to gray as {{FuncArg|output_high}} becomes smaller.

:{{Par2|coring|bool|true}}
::When ''true'' (the default),
::#input luma is ''clamped'' to the range 16{{D}}-235{{D}} and the chroma to 16{{D}}-240{{D}};
::#this clamped input is ''scaled'' from 16{{D}}-235{{D}} to 0{{D}}-255{{D}},
::#the conversion takes place according to the transfer function above, and then
::#output is scaled back to 16{{D}}-235{{D}}.
::When ''false'', the conversion takes place according to the transfer function, without any scaling.

::{{FuncArg|coring}} was created for VirtualDub compatibility, and it remains true by default for compatibility with older scripts.
::In the opinion of some, you should [http://forum.doom9.org/showthread.php?p=1722885#post1722885 always use ''coring=false''] if you are working directly with luma values (whether or not your input is 16{{D}}-235{{D}}).

::'''Note''' TV-range video ''can'' be correctly processed with {{FuncArg|coring}}=false; for example,
:::<code>Levels({{BoldColor|blue|104|0}}, 1.6, {{BoldColor|blue|104|255}}, {{BoldColor|blue|104|0}}, {{BoldColor|blue|104|255}}, coring=true)</code>  
::produces the same result as
:::<code>Levels({{BoldColor|blue|104|16}}, 1.6, {{BoldColor|blue|104|235}}, {{BoldColor|blue|104|16}}, {{BoldColor|blue|104|235}}, coring=false)</code>
::except that the output is not clipped to TV-range. Black and white levels are preserved while adjusting {{FuncArg|gamma}}, unlike
:::<code>Levels(0, 1.6, 255, 0, 255, coring=false)</code>  

:{{Par2|dither|bool|false}}
::When ''true'', [[ordered dithering]] is applied to combat [http://en.wikipedia.org/wiki/Colour_banding banding]. Default is ''false''.
