== Description ==
Frame Rate Converter based on the example from the MVTools documentation with some modifications. This script is also known as "jm_fps".
 
 
== Requirements ==
* [x86]: [[AviSynth+]] or [http://sourceforge.net/projects/avisynth2/ AviSynth 2.6]
* [x64]: [[AviSynth+]]
* Supported color formats: [[Y8]], [[YV12]], [[YV16]], [[YV24]]

=== Required Plugins ===
Latest versions of the following filters are recommended unless stated otherwise. 
* [[MVTools]]
* [[RgTools]]

:{{Template:FuncDef|JohnFPS (clip c, val "num", int "den", int "Sharp", int "rFilter", int "BlkSize", int "Search", int "dct", float "ml", int "Mask", bool "Blend") }}
 
::{{Par2| |clip|}}
:::Input clip.
 
::{{Par2|num|val| }}
::{{Par2|den|int| }}
:::Specify FrameRate using num (Numerator) and den (Denominator):
<div style="margin-left: 6em; max-width: 67em">
<pre>
num only, eg num=25.0: FrameRate = 25.0 FPS
num & den, eg num=24000, den=1001: FrameRate = 23.976 FPS (Both should be type Int).
neither parameter specified: FrameRate = Double input framerate.
</pre>
</div>
 
::{{Par2|rFilter|int|1}}
:::MSuper parameter; hierarchical levels smoothing and reducing (halving) filter.
:::* 0 : simple 4 pixels averaging like unfiltered [[SimpleResize]] (old method)
:::* 1 : triangle (shifted) filter like [[ReduceBy2]] for more smoothing (decrease aliasing)
:::* 2 : triangle filter like [[BilinearResize]] for even more smoothing
:::* 3 : quadratic filter for even more smoothing
:::* 4 : cubic filter like [[BicubicResize]](b=1,c=0) for even more smoothing
 
::{{Par2|Sharp|int|4}}
:::MSuper parameter; sub-pixel interpolation method.
:::*0 : soft interpolation (bilinear).
:::*1 : bicubic interpolation (4 tap Catmull-Rom)
:::*2 : sharper Wiener interpolation (6 tap, similar to Lanczos).

 
::{{Par2|BlkSize|int|16}}
:::Block size for MAnalyze and MRecalculate. Some suggestions:
:::*8 - for 320x240 (WEB)
:::*16 - for 720x576 (SD)
:::*32 - for 1280x720 (720p HD)
:::*32 - for 1920x1080 (1080p HD)
 
::{{Par2|Search|int|3}}
:::MAnalyse parameter; search decides the type of search at every level.
:::*search = 0 : 'OneTimeSearch'.
:::*search = 1 : 'NStepSearch'. It's the most well known of the MV search algorithm.
:::*search = 2 : Logarithmic search, also named Diamond Search.
:::*search = 3 : Exhaustive search. It is slow, but it gives the best results, SAD-wise.
:::*search = 4 : Hexagon search (similar to x264).
:::*search = 5 : Uneven Multi Hexagon (UMH) search.
:::*search = 6 : pure Horizontal exhaustive search.
:::*search = 7 : pure Vertical exhaustive search.
 
::{{Par2|dct|int|0}}
:::MAnalyse parameter; using of block DCT (frequency spectrum) for blocks difference (SAD) calculation. In particular it can improve motion vector estimation at luma flicker and fades.
:::*0 - usual spatial blocks, do not use DCT;
:::*1 - use block DCT instead of spatial data (slow for block size 8x8 and very slow for other sizes);
:::*2 - mixed spatial and DCT data; weight is dependent on mean frame luma difference;
:::*3 - adaptive per-block switching from spatial to equal-weighted mixed mode (experimental, a little faster).
:::*4 - adaptive per-block switching from spatial to mixed mode with more weight of DCT (experimental, a little faster).
:::*5 - SATD instead of SAD for luma
:::*6 - same as 2 only use SATD
:::*7 - same as 3 only use SATD
:::*8 - same as 4 only use SATD
:::*9 - similar to 2, use SATD and weight ranges from SAD only to equal SAD & SATD
:::*10 - similar to 3/4,use SATD weight is on SAD, only on strong luma changes
 
::{{Par2|ml|float|200.0}}
:::MFlowFps parameter; mask scale parameter. The greater values are corresponded to more weak occlusion mask.
 
::{{Par2|Mask|int|2}}
:::MFlowFps parameter; processing mask mode:
:::*mask=0 is simple backward and forward occlusion masks (fastest);
:::*mask=1 is similar masks with additional switching to static zero vectors at occlusion area;
:::*mask=2 is for using extra vectors from adjacent frames for decreasing objects halo at occlusion areas (slowest).
 
::{{Par2|Blend|bool|false}}
:::MFlowFps parameter; blend frames at scane change like ConvertFps if true, or repeat last frame like ChangeFps if false.
