    3gp and mp4 are essentially the same thing

    They're each limited in the actual codecs they can contain. If you want to turn anything into an mkv without re-encoding you use MKVMerge.

    MP4 generally only takes AAC audio (maybe AC-3) and mpeg video. It does take others but you're unlikely to find those other codecs in non-mp4 files.


    Any format to mp4 without re-encoding is a hard ask, the source would have to contain the right codecs to begin with.
