I am currently looking at how to "normalize" the volume of various video files without recompression, and documenting my findings here.
For MP4 video files, an easy solution appears to be AACGain, a command line utility that handles AAC audio. Simply run:
aacgain /r *.mp4
and all MP4 video files will be normalized. The process is entirely reversible (using the /u command), and involves no recompression at all.

This was a handy utility, thanks for pointing it out.
