View source for External filters

Rough classification of filters (in progress).

To make it easier for people to to find what they need here, the list includes both script function filters (see [[Import]]) and plugin filters (see [[Plugins]]).

A list of older plugins (for AviSynth v1.0x/v2.0x) which are still sometimes used can be found [[External_plugins_old|here]].

A large list of filters can be downloaded [http://www.64k.it/andres/dettaglio.php?sez=avisynth here] and [http://www.avisynth.nl/users/warpenterprises/ Warp Enterprises Avisynth Filter Collection]

A list of 64bit compiles can be found [http://yo4kazu.110mb.com/ here] and [http://code.google.com/p/avisynth64/wiki/PluginLinks here].

Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file.
# 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). 

AviSynth filters have been classified under these four basic tasks, with a fifth category for filters that fall outside this scheme, and a sixth category for filters that process audio only.

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].

| [[ReInterpolate411]]
| This is a fast simple filter to correct the improper 4:1:1 => 4:2:2 conversion that seems to occur with some DV/4:1:1 codes when used with Avisynth. It assumes the odd chroma pixels are duplicates and discards them replacing them with the average of the two horizontally adjacent even chroma pixels. It doesn't matter whether the clip is interlaced though it must be in YUY2 format for Avisynth 2.5. There are no parameters, and currently no readme file.

| [[ReInterpolate420]]
| Usually, DV decoders upsample PAL DV (which is YV12) to YUY2 using point sampling. This plugin reinterpolates the original chroma samples.

| GreedyHMA is an Avisynth filter that executes DScaler's Greedy/HM algorithm code to perform pulldown matching, filtering, and video deinterlace.

| TDeint is a bi-directionally, motion adaptive (sharp) deinterlacer. It can also adaptively choose between using per-field and per-pixel motion adaptivity. It can use cubic interpolation, kernel interpolation (with temporal direction switching), or one of two forms of modified ELA interpolation which help to reduce "jaggy" edges in moving areas where interpolation must be used. TDeint also supports user overrides through an input file, and can act as a smart bobber or same frame rate deinterlacer, as well as an IVTC post-processor.
