Export to what? What frame size at how many frames per second?
You would normally use the smallest of the frame sizes you have footage for. So 1920X1080. As for fps, my guess is that 24 is probably going to work out best for you.
yeah 1920x1080 is what I meant and yeah it's the smallest frame size, typing quickly here - and on deadline!
i assume I'll be exporting to QT and I want as much of a film look as is possible with all this different footage - so I assume exporting at 24fps is best...
follow-up question: trying to choose between the 1920x1080 sequences in premiere - should I edit on the Red 1080 24fps sequence? or does it matter?
It should not matter. Create your sequences by dropping your ProRes 24 footage on the New Item button. That is probably the easiest way. I don't think you will see any difference no matter which 1080p 24 preset you use.
Correct. If you're not using preview files they are all the same.
As for fps, my guess is that 24 is probably going to work out best for you.
I disagree. 24p works great when all your footage either is, or will be Interpreted as, 24p. But whenever you have any higher frame rates, PP doesn't do the best job of interpreting down to 24p. You'll get better results putting 24p media into 30i or 60p sequence (and export) than the other way around.
25 fps is going to be the problem. It won't 'fit' well into any NTSC frame rates.
When you say "if you're not using preview files" do you mean I should render ALL my footage before editing and not use the preview files? Couldn't I create the prores 1080 24fps sequence, edit all the different preview files and then render?
I ran a test with ProRes 24, 25 & 29fps as well as the Red footage in the same timeline. I exported from a 1080 sequence created by a prores422 24fps clip (by using the new item button as suggested). I exported with the following settings...
HD 1080p 23.976
sq pixels 1.0
Render at Max depth
Bitrate encoding: VBR 2Pass
Target BR: 20 Mbps
Max BR: 50 Mbps
And from what I can tell it all looks pretty darn good. I can see slight differences in 24 and 25. And certainly with the 29 and red footage. But it was never all mean to match seamlessly, as different sequences in the film have different looks. It just shouldn't look like a hot mess. I'm not positive yet, as I need to run more tests as footage comes in. but this may have done the trick. I'll keep updating... thanks !
