When saving a custom export preset, if the video codec is rawvideo and “Other” contains the line:
that line is not saved with the preset. It is saved if the line is pix_fmt=yuv444p or pix_fmt=yuv422p. Is this by design or a bug?
The export runs OK with pix_fmt=yuv420p and all is well; it just isn’t saved when you try to save the preset.
