Please note that the subject of this conversation is mp4 (not mp3).

Please also note that above quote was a continuation of this:

No need to explain why you don't have same/similar needs as the OP :-)

If you neither have a need for audio-in-movie nor for EBU R-128, then I 
doubt you'll be excited about melt or my script (even it it also 
supports modes where it bypasses melt and runs ffmpeg directly).

All that said, you are of course quite welcome to look at my script, and 
even critisize it if you like (no doubt there are things in there worthy 
of pointing fingers at).
