FFMPEG: Remux MTS files to MP4

I sometimes receive .mts video files made with Sony videocameras. These don’t play well on web video players or iOS devices. This is how, for most models, you can remux them to mp4 without converting and thus without losing quality and waiting a long time for the conversion to complete.

One file at a time

ffmpeg -i input.MTS -c copy output.mp4

Multiple files at once

While in directory with .MTS files

for f in *.MTS;do ffmpeg -i "$f" -c copy "${f%MTS}mp4";done

Remove MTS

rm *.MTS
