For the video, you'd probably want to do a stream copy, which will retain the original quality and save you from having to potentially wait a long time for it to encode: $ ffmpeg -i input-file.mov -c copy output-file.mp4 This works if the output container format supports the codecs used by the input file, which should be the case for most mov->mp4 conversions.
