Convert a bunch of MTS files from a camera to a sort-of-HTML5-compatible MP4's (while keeping the directory structure)
find /base_folder -name "*.MTS" -exec sh -c 'ffmpeg -n -i "$0" -c:v copy -c:a libfdk_aac "`basename "$0" .MTS`.mp4"' '{}' \;
Note:
The video track in the original MTS files most likely are H.264 High Profile, so they are not mobile-friendly.
Beware that the resulting MP4's may not play on older devices mobile. Change the base_folder according to your needs.
