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 here.

A large list of filters can be downloaded here and Warp Enterprises Avisynth Filter Collection

A list of 64bit compiles can be found here and here.

Most scripts will apply filters in the following order:

1. Create an AviSynth clip from a video file.
2. Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
3. Denoise the video (optional).
4. 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.

Chroma correction

Filter	Description	Color format	Plugin / Script	Author
BT709ToBT601	Convert from BT.709 (HDTV) to BT.601 (SDTV) colorimetry.	YV12	Plugin	Tom Barry
ChromaShift	This filter will shift the chrominance information by an even number of pixels, in either horizontal direction. It can also apply an overall vertical shift of the total chrominance information, up or down. It is primarily intended to correct improper colour registration. See discussion.	YV12, YUY2, RGB	Plugin	Simon Walters
ChromaShiftSP	This script can shift chroma in all directions with subpixel accuracy.		Script
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 discussion.	YV12, YUY2	Plugin	Wilbert Dijkhof tritical (v2.0+)
FixChromaBleeding	Fixes area of chroma bleeding by shifting the chroma and lowering the saturation in the affected areas.	YV12	Script	Alex Jordan
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.	YUY2	Plugin	Tom Barry
ReInterpolate420	Usually, DV decoders upsample PAL DV (which is YV12) to YUY2 using point sampling. This plugin reinterpolates the original chroma samples.	YUY2	Plugin	Wilbert Dijkhof Fizick (v3)
MoveChroma	MoveChroma is a simple filter combination that helps in moving chroma back, if it has been displaced.		Script
FixChromaticAberration	FixChromaticAberration resizes (and crops) the red/green/blue channels of the image separately. This helps to minimize the colored edges next to the image corners that result from lenses with chromatic aberration. See discussion.	RGB24	Script	Martin Wagener

Decomb	The FieldDeinterlace filter provides functionality similar to the postprocessing function of Telecide. You can use it for pure interlaced streams (that is, those not containing telecined progressive frames). The name refers to the fact that field mode differencing is used.	YV12, YUY2	Plugin	Donald Graft
GreedyHMA	GreedyHMA is an Avisynth filter that executes DScaler's Greedy/HM algorithm code to perform pulldown matching, filtering, and video deinterlace. It has pretty much been superceded by Donald Graft's Decomb package. However there may be occasions where it sometimes gives preferable results, especially with some bad PAL clips.	YUY2	Plugin	Tom Barry
IBob	Interpolating Bob works identically to the Avisynth built-in Bob filter except that it uses linear interpolation instead of bicubic resizing. See discussion.	YV12, YUY2	Plugin	Kevin Atkinson
KernelDeint	This filter deinterlaces using a kernel approach. It gives greatly improved vertical resolution in deinterlaced areas compared to simple field discarding. Superceded by LeakKernelDeint, see the description below in this table.	RGB, YV12, YUY2	Plugin	Donald Graft
LeakKernelBob	This filter does a full framerate deinterlacing, i.e. it turn 50 fields per second into 50 frames per second. Adapted from Scharfis_brain's script of the same name.	RGB32, YV12, YUY2	Plugin	Kurt Prünner
LeakKernelDeint	This filter deinterlaces using a kernel approach. It gives greatly improved vertical resolution in deinterlaced areas compared to simple field discarding. Compared to KernelDeint, it is low-level optimized (for speed) and provides some useful new functionality. As the original author of KernelDeint() states, LeakKernelDeint() is the preferred version to use.	RGB32, YV12, YUY2	Plugin	Kurt Prünner
MCBob	Another approach to motion compensated bobbing. No residual combing, Motion Masking adaptive to local complexity, self adaptive error correction for temporal interpolation, Motion Search between fields of same parity, and spatial Interpolation overweights spatio-temporal interpolation. Is SLOW. MCBob + EEDI2 [6] MCBob + NNEDI [7]		Script	Didée
MVBob	by scharfis_brain [8]		Script	scharfis_brain
QTGMC	by -Vit- [9] A new deinterlacer based on TempGaussMC_beta2. It's faster and has a presets system for speed/quality selection.

Securebob	type=2 or type=3. (part of MVbob) [10]		Script	scharfis_brain
SecureDeint	(part of MVbob) [11]		Script (?)	scharfis_brain
SmoothDeinterlace	by Gunnar Thalin [12]		Plugin	Gunnar Thalin
TDeint	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. See discussion.	YUY2, YV12	Plugin	tritical
Telecide Hints	The filter process the stats file to get the usual progressive matches and identify VFR sections.		Plugin
TempGaussMC	Motion-compensated bob deinterlacer, based on temporal gaussian blurring. reduces noise/grain of the source and does NOT leave the original fields unchanged. Output is rich with details and very stable. Is SLOW	YUY2, YV12	Script	Didée
TomsMoComp	This filter uses motion compensation and adaptive processing to deinterlace video source (not for NTSC film). See discussion.	YUY2, YV12	Plugin	Tom Barry
Yadif	Port of YADIF (Yet Another DeInterlacing Filter) from MPlayer by Michael Niedermayer (http://www.mplayerhq.hu). It check pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.	YUY2, YV12	Plugin	Fizick
Yadifmod	Modified version of Fizick's avisynth filter port of yadif from mplayer. This version doesn't internally generate spatial predictions, but takes them from an external clip. It also is not an Avisynth_C plugin (just a normal one).	YUY2, YV12	Plugin	tritical
TomsBob	We've asked Tom to include a proper 60fps deinterlacer in his wonderful TomsMoComp, but until then you'll have to make do with TomsBob.		Script

It can remove frames from a clip to achieve the desired frame rate, while retaining audio/video synchronization. It preferentially removes duplicate frames where possible. ("FDecimate" stands for "Free Decimate", which implies that the output frame rate may be freely chosen, and is not limited to 1-in-N decimation).	YUY2, YV12	Plugin	Donald Graft
GreedyHMA	GreedyHMA is an Avisynth filter that executes DScaler's Greedy/HM algorithm code to perform pulldown matching, filtering, and video deinterlace.

Deepcolor Filters

Filter	Description	Color format	Plugin / Script	Author
Deep Color Tools	This Script provides basic functions to import 10bit video, do color adjustments, and export to 8bit	V210	Script	jmac698
Dither	Generates video with up to 16 bits per component after denoising and dithers back to 8 bits for storage. Primarily written to smooth fine gradients to remove colorbanding during/after denoising. Can also recover high bitdepth data potentially contained in a noisy clip; dither a high bitdepth picture into a standard YV12; and perform basic operations (masking, curves...) on high bitdepth pictures, as they cannot be manipulated safely with conventional avisynth filters.
