Description
I have a movie with an AVC video track and an AAC audio track. In the Inspector window, the audio track, under "Format", says: "AAC, Stereo (L R), 44.100 kHz". Looks good.
The video track, though, under "Format", says: "VC Coding<<about 25 bytes of junk>>, 622 x 472, Millions".
Every AVC-encoded file displays like that. Being an old-school Mac guy, that screams to me that something should have been a Pascal string rather than a C string, but I'll leave that to you.

That is an HandBrake? bug, it just write garbage in the "name" field of the stsd atom. You can use dumpster to change it.

Replying to Ritsuka:

Seems so. I posted a patch to HandBrake?'s forum which fixes this in theory ( http://handbrake.m0k.org/forum/viewtopic.php?p=12294). QuickTime's normal behaviour from what I've seen is to show what the stsd says is the codec name in Get Info, and fall back to the decoder's cdci info only if that's null. Showing the junk matches with that, and since we don't have any control over the stsd for .mov/.mp4 files, I'd put this down to a QuickTime bug.
