Sorry, for my particular problem, it's slightly different from OP. But this is one of the few threads addressing this issue. Noone's responded to my thread that I posted.
I've tried all sorts of workflow tests, and they all ended up not right (blurred fields, field tearing, etc. basically not correct pulldown). My sequence is 23.976 progressive editing with 23.976 progressive footage. Copying into a 29.97i sequence DF doesn't work unfortunately, both in CS6 or the CC's. PPro won't add the pulldown correctly. I should be clearer: the sequence, as you step through frame by frame and playback, displays it with the correct pulldown, but when you export for 29.97i it doesn't do it.
My workaround has been to export 24p ProRes HQ (CC 2014), then bring it into AME CS6, where there I have access to the Codec Settings. CC 2014, either stand alone, or through PPro, will not give me access to the Codec Settings, regardless of sequence settings, source framerate, interpret footage, etc. I've tried them all, and none give me access to the Codec Settings. Maybe I'm missing something?
I'm sure the AE trip works just fine too, but it would just be eaiser and faster with AME.
Maybe this requires a new thread, but I think what I'm looking for is the correct workflow for PPro particularly. If the camera crew shot 23.976 progressive, and you have to deliver 29.97i, what the steps are front to end. In the beginning we decided it was better to cut in native framerate, and then convert final output to 29.97i, then convert to Mpeg2 spec. It would be nice to do the whole shebang from the PPro sequence itself, resulting in 1 transcode step.
Thanks for replying.
