Thanks Michael,
I did do video mixdowns with the resolution XDCAM HD 50Mbits MXF then exported to XDCAM MXF Op-1a. I had many crashes because of USB 3 conflicts, this is what Avid support said. I did get it to output to my c drive and thought everything was ok but recieved a rejection from channel 7 in australia.
All i was told that the files had severe vision faults that look like severe head clogs. And a few other severe vision faults.
Is this a common problem?
I read coming out of Avid in DNxHD is like coming out raw from the time line, so I hope these faults arent included in these files.
Cheers.
