![]() You can of course also use constant bitrate encoding: ffmpeg -i in.mxf -c:v mpeg2video -b:v 2M -c:a mp2 -b:a 128k out. This would re-encode the video to MPEG-2, with a variable quality of 2 (sane values are 2–5, range from 1–31, and lower meaning better): ffmpeg -i in.mxf -c:v mpeg2video -qscale:v 2 -c:a mp2 -b:a 128k out.mpg If you still get errors while transcoding, and you want to transcode instead of just copying the streams, please try downloading a recent static build for your operating system from the FFmpeg homepage.
