Outdated AviSynth plugins

External plugins (old) - these older plugins are not recommended, page is there mainly for historical purposes.

Using filters

Most scripts will apply filters in the following order:

1. Create an AviSynth clip from a video file using a source filter.
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).

Filter	Description	Color format	Plugin / Script	Author
DAA	Anti-aliasing with contra-sharpening.	YV12	Script	Didée
mcDAA3	Motion-Compensated Anti-aliasing with contra-sharpening, 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

caf	Chromatic Aberration Fixer.	YV12	Script	Torchlight
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, RGB32	Plugin	Simon Walters
ChromaShiftSP	This script can shift chroma in all directions with subpixel accuracy.	YV12, YV16, YV24, YV411	Script	IanB, McCauley
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. See discussion	YV12	Script	Alex Jordan
FixChromaBleedingMod	Fixes area of chroma bleeding by shifting the chroma and lowering the saturation in the affected areas. See discussion	YV12, YUY2, YV411	Script	AmjadSONY
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, RGB32	Script	Martin Wagener
MoveChroma	Chroma shifting filter; can be used to independently shift the U/V channels left or right.	YUY2, YV12	Plugin	apechironnup
ReInterpolate411	This is a fast and simple filter to correct the improper 4:1:1 => 4:2:2 conversion that seems to occur with some DV/4:1:1 codecs.	YUY2	Plugin	Tom Barry
ReInterpolate420	Usually, DV decoders upsample PAL DV (which is YV12) to YUY2 using point sampling. This plugin re-interpolates the original chroma samples.	YUY2	Plugin	Wilbert Dijkhof Fizick (v3)

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, YUY2, YV12	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.	YUY2, YUY2	Plugin	Donald Graft
EEDI2	EEDI2 resizes an image by 2x in the vertical direction by copying the existing image to 2*y(n) and interpolating the missing field. It is intended for edge-directed interpolation for deinterlacing (i.e. not really made for resizing a normal image, but can do that as well).	YUY2, YV12	Plugin	tritical
EEDI3	Another edge directed interpolation filter. Works by minimizing a cost functional involving every pixel in a scan line. eedi3 is good for deinterlacing and enlarging images by the powers of 2.	RGB24, YUY2, YV12	Plugin	tritical
FieldHint	FieldHint combines arbitrary fields from the input clip, and optionally adds Telecide-compatible postprocessing hints.	YV12	Plugin	Loren Merritt
IBob	Interpolating Bob works identically to the Avisynth built-in Bob filter except that it uses linear interpolation instead of bicubic resizing. See discussion.	YUY2, YV12	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, YUY2, YV12	Plugin	Donald Graft
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, YUY2, YV12	Plugin	Kurt Prünner
nnedi3	nnedi3 is an intra-field only deinterlacer. It takes in a frame, throws away one field, and then interpolates the missing pixels using only information from the kept field. It also has same rate and double rate modes.	RGB24, YUY2, YV12	Plugin	tritical
nnedi3ocl	OpenCL rewrite of nnedi3. See discussion.	Y8, YV12, YV16, YV24, YV411	Plugin	SEt

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
TelecideHints	The filter process the stats file to get the usual progressive matches and identify VFR sections.	YUY2, YV12	Plugin	Myrsloik
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	YV12	Script	Didée
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
yadifmod2	Yadif + yadifmod for avisynth2.6/avisynth+. See discussion.	YV24, YV16, YV12, YV411, Y8	Plugin	Chikuzen

ApparentFPS	Shows underlying framerate where a clip has had many duplicates inserted, easier than counting unique frames.	(see docs)	Plugin	StainlessS
Dup	A robust duplicate frame detector; a frame that is determined to be close enough to its predecessor to be considered a duplicate will be replaced by a copy of the predecessor. This can significantly reduce the size of encoded clips with virtually no visual effect. Provides the capability to replace frames with a blend of all the duplicates, providing a valuable noise reduction. See original and continued discussion.	YV12, YUY2	Plugin Update (v2.32a)	Donald Graft
Dupped	Another frame duplication function, similar to Dup, but hopefully more accurate. See discussion.	YV12	Script	Corran
DeDup	Remove (drop) duplicate frames in the interest of compression quality and speed. Resulting clip will have a variable frame rate.	YV12, YUY2	Plugin	Loren Merritt
ExactDedup	ExactDedup is a filter intended to remove frames that are exact duplicates of each other, leaving only the first and (optionally) last frames of a run intact, and generates a Matroska v2 timecodes file with timing information for the ensuing stream. See discussion.	RGB24 RGB32, YV12	Plugin	Steve Melenchuk, Arick Chan
GetDups	Selecting unique duplicate frames from clip, it return frames which have copies only, by one from the series (group). Made for 8mm films.	Y8, YUY2, YV12, YV16, YV24, YV411	Plugin	Fizick
