> I'm trying to remux a MXF XAVC file with the exact same video but
> only 2 out of the 4 audio tracks.
> For that I use this command:
> ffmpeg -i INPUT_FILE -c copy -map 0:v -map 0:a:0 -map 0:a:1 OUTPUT_FILE
> The thing is, some video data are lost during the remux as my file
> is smaller than it should be.
