Revision as of 12:48, 14 October 2013

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.

Restoration Filters

These remove effects or artefacts introduced (deliberately or accidentally) into the source video. Denoisers are classified separately.

Anti-aliasing

Filter Description Color format Plugin / Script Author
AAA Anti-aliasing filter designed for anime. See discussion. YV12 Script Soulhunter
AntiAliasing Anti-aliasing script for, well, anti-aliasing. See discussion. YV12 Script SpikeSpiegel, Didée, mf, scharfis_brain and Soulhunter
AntiAliasRG An anti-aliasing script that uses RemoveGrain(SSE3).dll. See discussion. YV12 Script Bloax
DAA Anti-aliasing with contra-sharpening. Included in AnimeIVTC. YV12 Script Didée
mcDAA3 Motion-Compensated Anti-aliasing with contra-sharpening by AmjadSONY, can deal with ifade too, created because when applied daa3 to fixed scenes, it could damage some details and other issues. See discussion YV12 Script AmjadSONY
FAA Faster Anti-aliasing. See [1]. YV12 Script list
MAA Anti-aliasing with edge masking. Included in AnimeIVTC. YV12 Script martino, Kintaro, thetoof
SangNom A single field deinterlacer, can also be used for anti-aliasing. See discussion. YV12 Plugin Marc FD
SangNom2 rewrite of the old SangNom filter. Its output is mostly identical to the old version on default settings. which has:-

1-Correct borders processing 2-Additinal colorspace support 3-Multithreading support. See discussion.

YV12, Y8 Plugin TurboPascal7
SAA A simple anti-aliasing script. See discussion. YV12 Script Soulhunter
SharpAAMCmod High quality MoComped AntiAliasing script, also a line darkener since it uses edge masking to apply tweakable warp sharpening, "normal" sharpening and line darkening with optional temporal stabilization of these edges. Part of AnimeIVTC. See [2] and [3] Script thetoof
TIsophote A level-set (isophote) smoothing filter, see [4] YV12 Plugin tritical

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. 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. Script

Debanding

Filter Description Color format Plugin / Script Author
AdaptDBMC Luma / Fade / Blue adaptive debanding script. YV12 Script 06_taro
GradFun2DB DeBanding Filter. See wikipedia:Color Banding YV12, YUY2, RGB24, RGB32 Plugin Prunedtree

HQDering Applies deringing by using a smart smoother near edges (where ringing occurs) only. See here and here for details. YV12 Script mf
MosquitoNR A noise reduction filter designed for mosquito noise, which is often caused by lossy compression. Y8, YV411, YV12, YV16, YV24, YUY2 Plugin b_inary

Deinterlacing

Filter Description Color format Plugin / Script Author
Area A port of Gunnar Thalin's VirtualDub filter "Deinterlace - area based" to AviSynth. RGB32 Plugin Donald Graft // Gunnar Thalin
BlendBob Filter designed for use after a smart bob; blends every other frame with the closest matching neighbouring frame. See discussion. YV12 Plugin Kurt Prünner
DGBob This filter splits each field of the source into its own frame and then adaptively creates the missing lines either by interpolating the current field or by using the previous field's data. See discussion. RGB, YV12, YUY2 Plugin Donald Graft
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. Script Didée
MVBob by scharfis_brain [13] Script scharfis_brain
QTGMC by -Vit- [14] A new deinterlacer based on TempGaussMC_beta2. It's faster and has a presets system for speed/quality selection. There are also several new features including progressive support and noise/grain processing. The script also contains extensive comments to better describe the settings and the workings of the TGMC algorithm. Script -Vit-
Securebob type=2 or type=3. (part of MVbob) [15] Script scharfis_brain
SecureDeint (part of MVbob) [16] Script (?) scharfis_brain
SmoothDeinterlace by Gunnar Thalin [17] 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

IVTC & Decimation

Filter Description Color format Plugin / Script Author
AnimeIVTC What it does:
  • 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

See [18]

Script thetoof
BruteIVTC Plugin MarcFD
DOCI Destruction of Chroma Interlacing fixes a problem where you captured pulleddown video in YV12. In the combed frames, the chroma from two frames has been blended, leading to a ghosting effect when IVTC'd. This filter reconstructs the chroma exactly and fixes the problem. Script jmac698
FDecimate The FDecimate() filter provides extended decimation capabilities not available from Decimate(). 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. It has pretty much been superseded 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
IT Inverse Telecine YUY2, YV12 Plugin thejam79 / minamina
ivtc_txt60mc Deinterlaces telecined footage with that has been overlayed scrolling text at 60i. Script cretindesalpes aka Firesledge
MultiDecimate Removes N out of every M frames, taking the frames most similar to their predecessors. See discussion. YUY2 Plugin Donald Graft
PFR PFR (Progressive Frame Restorer) is an Avisynth filter that attempts to produce progressive frames from a mixed progressive/interlaced/IVTCed source. YUY2 Plugin Simon Walters
ReMatch Plugin
RePal Plugin
SmartDecimate Smart Decimate removes telecine by combining telecine fields and decimating at the same time, which is different from the traditional approach of matching telecine frames and then removing duplicates. See discussion. YUY2, YV12 Plugin Kevin Atkinson
Decomb The Telecide and Decimate filters can be combined to implement IVTC. YUY2, YV12 Plugin Donald Graft
TIVTC A package containing these 7 filters: TFM, TDecimate, MergeHints, FrameDiff, FieldDiff, ShowCombedTIVTC, and RequestLinear. Also contains these 3 conditional functions: IsCombedTIVTC, CFieldDiff, and CFrameDiff. Designed primarily for IVTC operations. Discussion YUY2, YV12 Plugin tritical
TPRIVTC Plugin
UnComb Filter for matching up even and odd fields of properly telecined NTSC or PAL film source video. See discussion. YV12 Plugin Tom Barry

FixVHSOversharp FixVHSOversharp attempts to repair the light and dark halos that follow high contrast edges found in VHS sources. See discussion. YV12 Plugin MrTibs
GhostBuster Ghostbuster is an Avisynth filter for removing "ghosts" from a clip. A ghost in this context is a faint copy of the picture offset horizontally. It works by either subtracting or adding the image from itself at the specified offset. With some tweaking the result, while not perfect, can be very pleasing. See discussion here and here. YUY2 Plugin SansGrip
LGhost Plugin intended for ghost removal but can also reduce edge (ringing) artifacts. See discussion. YV12, YUY2 Plugin minamina

Logo Removal

Filter Description Color format Plugin / Script Author
DeKafka This fairly simple filter washes away those annoying bugs from broadcast clips. Script

Luma Equalisation

Filter Description Color format Plugin / Script Author
Antiflicker "A quick-and-dirty port of my VirtualDub filter (which sucks, by the way; it was one of my first filters)."

See discussion.

YUY2 Plugin Donald Graft
DeFlicker Can remove old film intensity flicker by temporal mean luma smoothing. Can also correct blinding of automatic gain control after flashes. YV12, YUY2 Plugin Fizick (Alexander G. Balakhnin)
Dumb Deflicker Gathers average luma of frames, smoothens that with temporalsoften, and applies the obtained difference to the original input. It is pretty simple, read "dumb". See discussion YV12 Script Didée
EquLines Equalizes total luminosity in pairs of even and odd lines. Useful for removing inter-line differences from telecined films. YV12, YUY2 Plugin Fizick
LMFlicker LMFlicker is intended to reduce flickering in some film/vhs transfers. FieldFade is a similar concept, but applied on a per-field basis, to reduce combing in a video where fades were applied after telecine. YV12 Plugin Loren Merritt
Local Deflicker Deflickers only part of a frame. See discussion. YV12 Script prokhozhijj
ReduceFlicker Reduces temporal oscillations in clips; should be applied before deinterlacing. Contains ReduceFlicker, ReduceFluctuations, and LockClense. See discussion. YV12, YUY2 Plugin Kassandro
