24p to ProRes using Compressor?
Hi all,
I want to use Compressor to remove the pull-down on some 24p footage and convert it to ProRes but I’m not sure which settings to use. I have run some tests using the “Apple ProRes 422 for Progressive” settings, checked “reverse telecine” and specified the frame size I need. This results in a file that integrates seamlessly into my ProRes timeline in FCP without requiring any rendering but looks noticeably interlaced and consequently not so good when I play it back. Is this because I’ve used the wrong settings in Compressor? Should I have used the “Apple ProRes 422 for Interlaced” settings?
Thanks!

Hi Dave, thanks for the response.
I’m talking about individual clips shot at 24p. I need to convert them before I edit because I need to work with them in a 23.98 timeline intercut with ProRes 23.98 footage. I did not shoot or capture the footage but I was told it was shot at 24p and the quicktimes that were given to me are at 29.97 so I assume they were captured using the DV NTSC preset.
Since posting I have noticed that some of the clips I run through Compressor actually come out looking smooth and others do not. When scrolling frame by frame through the original clips that generate a smooth result I can identify the two out of every five frames that are interlaced. When doing the same with the original clips that generate the completely interlaced result, every frame looks interlaced. Does this suggest that the original clips might have been shot in both 24p and 24pA by accident and captured all using the DV NTSC preset? Would capturing 24pA in this way have resulted in a completely interlaced clip? Sorry for the backwards logic, I’m trying to figure out if I’m going to need to rustle up the original tapes and do a complete recapture or not.
Thanks,
Tory

Whoops, yes, browser confirms that they were captured DV/DVCPRO – NTSC. Thanks for the explanation of the interlacing patterns, I am going to employ your final suggestion and hopefully get to the bottom of how to footage was originally shot. If indeed the clips that are appearing interlaced were shot in 60i then having captured them using the DV-NTSC preset would have been proper procedure, is that correct?

Thanks Dave! This has made my headache subside considerably.

One more question: what if I conform the 29.97 clips to 23.98 using Cinema Tools and then run them through Compressor to convert them to ProRes? Is that an adequate method?
