That's because it should have been 29.97 frames/sec.... INTERLACED. That's what the "i" in 1080i stands for. Upper field first for 1080.
At 1080, it's 59.94 FIELDS.... not frames. At 720? Different story: you can have 59.94 complete frames.
Dave, thank you for your help. But I've tried everything I can think of.
Would you be able to be more specific? I am working in an Avid project with a format of 1080i/59.94.
Without me confusing the issue (and recounting my failures) - what should my comp setting be and how should I export to QT?
I hope that's not too much to ask but I have been trying to do this for a long time!
Well, are your Avid project settings actually okay and is the hardware initialized properly? Also try to import the files without fields, even when rendered interlaced from AE. Over the years there have been any number of bugs with this where sometimes the fields are interpreted twice or the order has been reversed. Also try "even" framerates like 30 FPS/ 60 FPS and then force-interpreting to different framerates. And finally of course try another CoDec. Just missing a simple setting in DNxHD can make a mess.
