Hi,
I use the one shipped with Staxrip, should be this one, 2.23.1 :
https://github.com/FFMS/ffms2/releases
I saw in vapoursynth documentation that is supported some LUT's when i was searching for this long time ago but not using vapoursynth i did not pursue in this direction, thanks for the links, I'll try to do a request in the forum thread you linked and see how it goes , this will be really neat if possible with avisynth, have nothing to loose asking
Thank you
