Turning the Colormatrix filter on or off does not affect.


RE: Conversion HDR to SDR - Selur - 15.01.2023

ColorMatrix will only adjust the color matrix and not handle the HDR meta data. (those are different things!)
If you want to convert HDR to SDR, you need to use tone mapping filters like under 'Filtering->Vapoursynth->Color->HDR to SDR'.
Hybrid does not support tone mapping through Avisynth, but you can write a custom section and adjust the mapping yourself using filters like:
  • DGHDRtoSDR
  • DGTonemap
  • libplacebo_Tonemap
see: http://avisynth.nl/index.php/External_filters
