I realized that the Pro Res encoder that’s used by default by ffmpeg is from proresenc_anatoliy.c.
However, this variant of the encoder does not support the 4444 profile.

The other Pro Res decoder proresenc_kostya.c does also support 4444.

Is there an easy way to configure FFMPEG to use the other encoder or does this require other changes?

Thanks,

Flo
