External filters

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see Import) and plugins (see Plugins).

Introduction

Download sites

A large list of filters can be downloaded from the following sites but be aware that some plugins listed may be outdated, only recommended as a backup.

• Andres' Filter Collection
• AviSynth Filter DB by ChaosKing | mirror
• AviSynth.info Filter Archive
• XhmikosR's Builds
• Warp Enterprises' AviSynth Filter Collection

64-bit filters

A comprehensive list of 64-bit filters is available in the AviSynth+ page.

Outdated AviSynth plugins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).

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

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

YV12	Script	thetoof
BruteIVTC	Some information here	YV12	Plugin	Marc FD
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.	YV12	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.
