Vapoursynth ColorMatrix won't work
#1
Hi.
I use Hybrid version 2020.12.13.1 and Windows 7 64bit
What i do:
1) Load my .mp4 file (AVC/AAC)
2) Checking box "ColorMatrix" in Vapoursynth section and set to:
From: Rec.601/470bg/470m To: Rec.709 Clipping: pre and post.
3) If I press preview, then it works fine in preview. I can see color changing
4) Encode my video to mp4 (avc/aac, 1920x1080) - nothing changed. Colors are the same as in input video

Similar steps with the same input file and output settings work fine with ffmpeg or Avisynth.

P.S. I thought maybe Vapoursynth doesn't work on my system for some reason but it works. I tried to change Levels, encoded a video - effect is there. So something wrong with ColorMatrix.

Without a debug output which includes the source analysis and the job processing I can't really tell what's going on.

LOL, found the issue: Vapoursynth wasn't used. Smile
This was caused due to some old code when Avisynth/Vapoursynth/FFMpeg shared one ColorMatrix interface.
(would have worked if you had used another Vapoursynthfilter in addition to ColorMatrix Wink)

-> I'll compile a new fixed dev version and send you link via PM once it's compiled, packaged and uploaded. (~30min)
