I am not sure I understand: Do you mean that FFmpeg detects the aspect ratio incorrectly? If yes, this should be fixed first (and all remaining issues depend on this). [...] > $> ffmpeg -i in.mxf -vcodec copy -aspect "16:9" -an out_copy.mxf This does not work because libavformat writes mxf aspect ratio differently from all other containers (sadly). To some degree this is related to the fact that mxf aspect ratio is defined in a rather brain-dead way.

This is certainly not true but as said, mxf aspect in FFmpeg on muxing is different from other containers. (And this is a bug imo.)
