Working with motion graphics in After Effects and normally export out QuickTime RGB+Alpha, DNxHR/DNxHD and import into Avid as a Alpha Channel Invert on import white = opaque.
Lately on 8.9.2 the QT imports are breaking up, so I switch over to AVI export from AE which are just as clean and work fine when importing. Still curious as to why QT is giving me trouble?
