AviSynth Filter Collection |
This is only a collection of filters with no guaranty of
completeness or maintenance of the latest version.
For more details and discussions visit Doom9's
AviSynth Forums and
AviSynth Homepage.
Friend pages with the latest versions:
fizick's
filters stickboy's
filters tsp's
filters vcmohan's
filters tritical's filters AvsP
Plugins for old AviSynth versions and some depreciated plugins can be found here.
You can download a snapshot of the homepage (2005-04-08, unpack to a directory using pathnames).
Scroll down to some files that are no filters but quite useful when working with AviSynth.
The naming scheme for the files is:
dllname_20_dll_20030102.zip: version is for AviSynth 2.0x,
contains DLL and maybe sourcecode and docu
dllname_25_src_20030102.zip: version is for AviSynth 2.5,
contains only source code
The date is either the date of the DLL or of the most recent
source file.
The links in the WWW-column are intentionally only text, as they are
not checked, sometimes only the homepage of the author, etc.
