conforming 24p footage in a 30 seq with audio back to 24p
So here is what I did. I used Panasonic 720p footage at 24fps and edited in a 29.97 timeline which did the repeat every fourth frame thing and resized the footage to letterbox. I edited a music video and synced the audio. Now I want to make an HD master. So I copied the timeline into its native 720/24 sequence, removed distort and basic motion attributed to get it back to full screen HD, and removed the annoying gaps that it left by taking out the repeated 4th frame. Now my audio doesn’t match. What is the best way to get the sequence to sync up again? And how do I make a 30fps HD master and get it to sync as well? In Smoke it was as easy as doing a speed change on the video, but they don’t look good in fcp and the speed conventions are different so I don’t know the proper speed change value to use.
THANKS!!!

scratch that. what I meant was that the original footage is 720p60 not 720p24, but its at 23.98 frame rate.

Panasonic ONLY uses the standard 3:2 pulldown. so 2 dupes, then 3 dupe frames.

How? it sounds as if you did not remove the pulldown properly especially if you did not understand the correct cadence of the dupe frames.
why not try doing this –
running all of your content thru the FRC,
converting your edl from 30 – 24 .
reimporting the content,
then relinking the audio track.gary adcock

well in FCP 6 when you pull the 23.98 footage into a 30 timeline, it doesn’t add pulldown, it just repeats the fourth frame. Why? I have no clue. It makes no sense. If I would have done the conversion before editing that would have been better, but now I have to go in reverse.

its been that way since FCP 3.02.
it is the same cadence that Sony uses for its HD- SD conversions.
it is a 2:2:2:4 cadence, and both compressor and FCP do the same thing, it can be removed in CT however – but you need to read the manual to be able to do it.gary adcock
