> You tried to set parameters from down (input) to top?
I don't know if I understand what you mean correctly. Anyway, I tried
putting values (corresponding to bt2020) to the following paramaters,
one at a time. Here are the results:
matrixin --> 9 --> OK
min --> 9 --> OK
transferin --> 14 --> OK
tin --> 14 --> ERROR
primariesin --> 9 --> OK
pin --> 9 --> ERROR
So, you can manually edit keyframe with desired parameters?
Can you also post your system's ffmpeg banner output and version of zimg so I can try to ask about this error on zimg github?
