I exported my typical QT Ref .mov out of Avid but because I had mixed frame rates Avid forces the audio to be mixed down. I work around this by exporting a QT Ref with the audio mixed down to 2 tracks. I then do a second audio only QT Ref export of the sequence to maintain in this case all 12 discrete tracks. In QT Pro 7 I remove the stereo audio mixed down tracks and then edit in the 12 discrete tracks. Then I do a Save As and all is generally well.
Today I got a QC rejection stating:
"The MOV file has a bad logical track order. Audio track atoms do not directly follow video track atoms."
The only difference I can see in QT Pro 7 is in the properties window. For this file the order top to bottom of tracks is Video then Time Code and then the 12 audio tracks. On previous files that passed what they call the "sniff" test the order is Video then 12 audio tracks then time code. Given the above QC note I'm wondering if this is why the file is being flagged?
Any insight would be welcome. I'm going to contact the QC folks for clarification as to what raised the ref flag. I don't understand why the track order is problematic given the file works fine in QT Player and will ama back into Avid fine and I've used this workflow without issue for years.
