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???!
I thought in a .mov the video and audio are essentially one file? I would think a seperate audio track would have to be extracted, processed and then re-encoded. That would an interesting thing if you could do what you are talking about. I'd like to know about that!
