Mind boggling sound!!? Does it sync? What goes on? Shooting at 1080 or 720 p editing in 23.98 or 60, confused!
Okay, talking about shooting at different frame rates, how do people do it when they shoot 720p, or 1080pa with the advanced pulldown.
I plan on recording sound both on a fostex field recorder and directly to the camera.
When shooting 1080pa, its really 60fps being recorded right? then editing in 23.98 just confuses me, how is the sound going to sync, what is the workflow thats supposed to happen?
What happens in the sound world of all of this? Syncing, getting the field recorder to know that your shooting 60 fps and latter going to edit in 23.98, does this throw things out of wack? How do you deal with this stuff, this is totally mind boggling I never even thought about this.

The whole 60fps thing is ‘behind the scenes’ and if you’re recording to P2 you won’t see or deal with your footage as such.
I’m sure someone will set me straight if I’m wrong here, but…
24PA is recorded over 30fps with flags set for automated pulldown removal on ingest. Since the camera will recording and be feeding 29.97 TC, I’d say that’s what the audio recorder should be doing as well.
On ingest that 29.97 recording will be trimmed down to 23.98 and I assume the clips will have the original TC with lots of skipped numbers, but each remaining frame’s TC will still match the TC on the audio.

Still confusing. I am using a fostex field recorder. If I shoot at 1080pa, that means its recording at 29.97 fps, but I will actually be doing a pulldown to make it 23.98 in the fcp timeline. Soo, I should set my fostex to 23.98? And it will sync perfectly to the pulldowned footage?

I’m not sure, hopefully someone who knows will chime in, but it seems to me you should be setting the Fostex to 29.97 because your video is actually being recorded at 29.97. If the two devices aren’t keeping track of frames at the same rate then how would they sync later?
Like I said above, I would think the 29.97 movie after advanced pulldown removal will have less frames per second, but the remaining frames will still have the original TC numbers – so the TC will skip a number every few frames but still have numbers that relate directly to the audio recording.
One second of audio is one second regardless of whether the video is viewed as 24 or 30 frames, you just need to know where to line it up, right? Having the audio deck track 24fps while being fed 30fps TC seems like you’d have real issues syncing later on.
