AviSynth2.5擴展濾鏡

除了內置的濾鏡和函數，AviSynth 2.5有能完成各種工作的眾多需要加載的外部濾鏡，我們把各種濾鏡分類並介紹其作用。

插件一篇介紹如何調用AviSynth 2.5的插件（Plugin），此外有眾多的腳本。你也可以自己編寫腳本函數。

源濾鏡

名稱	描述	下載	作者
FFmpegSource2	用ffmpeg打開文件，提供對mkv、mp4文件的準確跳轉。	[1]	Myrsloik
DGDecode	從DVD的vob、mpeg2流（包括.ts、.m2ts、.pva）中解碼MPEG1、MPEG2視頻。是原先的MPEGDecoder/MPEG2Dec3的替代者。	[2]	Donald A. Graft
DGAVCSourceNV

IVTC和反交錯

名稱	描述	下載	作者
AAD(Auto Anime Decomb)	AAD是專門為動畫片設計的，解除交錯用Avisynth腳本。	腳本	diseac
AVSSFSIVTC	腳本形式的IVTC插件。	插件	sswroom
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 [3] MCBob + NNEDI [4]	原版腳本	Didée
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.	插件	tritical
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	腳本	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.	插件	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).	Plugin	tritical
