From experience I can tell you that when I export an SD QT ref movie and use QT Pro to make it a self contained movie with multiple audio tracks when I ama back into Avid to check the field order is default and is wrong. If I don't manually set the right click source settings and choose even lower it won't playback correctly. This is an Avid 1:1x media, the x for packed not 10 bit, at least that's what QT Pro says it is. At any rate it's avid media and Avid's ama guess is default for field order and it's wrong every time...
