== [[Script variables|Syntax and Parameters]] ==
 
=== DctFilter ===
For each 8x8 block it will do a Discrete Cosine Transform (DCT), scale down the selected frequency values, and then reverse the process with an Inverse Discrete Cosine Transform (IDCT). 
In the following example the highest frequency components in each row and column will be zeroed while the 2nd highest would be cut in half.
:<code>DctFilter(1,1,1,1,1,1,.5,0)</code>
The row & column parameters are multiplied together to get the scale factor for each of the 64 values in a block. So if the top left value was V[0,0] then in the example above the we would scale row 6, col 6 (V[6,6]) by .5 * .5 = .25. 
Note that while they look like floating point parameters above they really now only
have 3 bit accuracy so the only actual values used are 0, {{Frac|1|8}}, {{Frac|1|4}}, {{Frac|3|8}} ... 1.0. But you can specify any value and it will be rounded to the nearest one.
 
 
:{{Template:FuncDef|DctFilter (clip, float, float, float, float, float, float, float, float, int "chroma", int "fdct", int "idct", int "offx", int "offy")}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2| |float| }}
:::There are 8 positional floating point parameters, all of which must be specified as in the range (0.0 <= x <= 1.0). These correspond to scaling factors for the 8 rows and columns of the 8x8 DCT blocks.
:::The leftmost parameter corresponds to the top row, left column. This would be the DC component of the transform and should always be left as 1.0.

=== DctFilterD ===
DctFilterD works similar to DctFilter but will zero out DiagCt number of the lower right diagonals of the DCT, leaving other values unchanged. 
In an 8x8 DCT result matrix there are 15 possible diagonals (visualize a chess board), so if you specify <code>DctFilterD(4)</code> then the 4 diagonals in the lower right corner of the DCT result will be set to 0. I haven't tested this much but, like my results with custom quant tables, it appears if you set DiagCt very large you will start to get edge noise, something like ringing.[http://forum.doom9.org/showpost.php?p=266216&postcount=145]

==Description==
It performs deblocking on the picture, using the deblocking filter of H264. It's useful to deblock the result of ''MVCompensate'' of [[MVTools]] plugin, etc. 

 
== Requirements ==
* AviSynth 2.6.0 or later
* Supported color formats: All planar formats
 

== [[Script variables|Syntax and Parameters]] ==
:{{FuncDef|Deblock (clip, int "quant", int "aOffset", int "bOffset")}}
 
::{{Par2| |clip| }}
:::Input clip.

::{{Par2|quant|int|25}}
:::The higher the quant, the stronger the deblocking. Range is from 0 to 60.

::{{Par2|aOffset|int|0}}
:::Quant modifier to the blocking detector threshold. Setting it higher means than more edges will deblocked.

::{{Par2|bOffset|int|0}}
:::Another quant modifier, for block detecting and for deblocking's strength. There again, the higher, the stronger.

::{{Par2|planes|string|"yuv"}}
:::Specifies which planes to process between y, u and v.
 
:*If {{FuncDef3|quant}} + {{FuncDef3|aOffset}} is less than 16, the filter does nothing at all. The same goes for {{FuncDef3|quant}} + {{FuncDef3|bOffset}}.
 

==Examples==
Deblock with default settings:
MPEG2Source("Blocky.dv2")
Deblock(quant=25, aOffset=0, bOffset=0)

To deblock the motion compensation ([[MVTools]] plugin):
<pre>
vectors = source.MVAnalyse(isb = false, lambda = 1000)
compensation = source.MVCompensate(vectors, mode = 0)
compensation.Deblock()</pre>
 

== Changelog ==
Version Date Developer Changes 
v1.3 2018/05/29 MysteryX - Back-ported from VapourSynth with high-bit-depth support
v0.9 2013/12/03 tp7 - Faster and supports all planar colorspaces
v1.2 2006/04/23 Fizick - Moved code into separate project
