I am looking for a way to adjust the volume tag within quicktime movies (not muxed mpegs but actual mpeg-4 video files with AAC audio tracks) on a large number of .mov files. I have a hundreds of music videos that have levels all over the place. This is an easy fix for mp3s, but I can't find anything that normalizes the AAC tracks within a .mov.

iVolume does work but makes changes only to the iTunes db, not the actual file itself (or so I believe). I don't want to have to re-encode the audio either, just a simple adjustment to the volume tag within the .mov.

Any ideas???!
