Glithes on the preview and in the destination file
|
Used script is:
ClearAutoloadDirs() ClearAutoloadDirs() => Can't reproduce this. No clue what is causing this. Can you share a short sample of your source which allows reproducing the issue?

Libav software decoder can't handle these. (FFmpegSource2 and LWLibavVideoSource both fail)
Using DGDecNV or libav hardware decoding also shows errors. This seems this only happens when using Avisynth. Lowering MT-Threads to 1 seems to somehow fix it, at least partially. Enabling 'Disable MT' does fix it here. Seems like it's an issue with the colormatrix filter handling the video stream and Avisynth threading. Hybrid uses the ColorMatrix filter from https://forum.doom9.org/showthread.php?t=173259 which afaik is the newest and first version to support conversions from and to Rec.2020. => It's not really a bug of Hybrid. I would recommend: a. enable 'Disable MT' for this source, or b. switch to Vapoursynth You could also try whether using the 64bit version from https://github.com/sorayuki/ColorMatrix/...s/tag/v2.6 helps. But reading https://forum.doom9.org/showthread.php?t=175279 there might be issues with it and I would really recommend to not use it in Avisynth for Rec2020->Rec.709 conversions. Cu Selur

Quote:enable 'Disable MT' for this sourceHow much can slow down processing by enabling this option? Quote:You could also try whether using the 64bit version from https://github.com/sorayuki/ColorMatrix/...s/tag/v2.6 helps I downloaded from this link "colormatrix.dll". This file is identical to the file "c:\Program Files\Hybrid\32bit\avisynthPlugins\ColorMatrix.dll" I need to replace "c:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\ColorMatrix64.dll" ? Where can I get this file?

Forget that, that version is a 32bit dll.
![]() The only 64bit version I know of is the one Hybrid already uses. Quote:How much can slow down processing by enabling this option?If ColorMatrix and resizing with point resizer is the only thing, it might even be faster. (I don't really expect any slow down with just these filters, but simply try it.) Cu Selur
