How do you use 25 FPS footage as 24 in FCP?
Hi all. Without a progressive “HD” option right now, I decided to experiment with shooting PAL HDV (50i), deinterlacing, and then using it as 24P while slowing the sound down and possibly pitch-shifting it back. This is a workflow I’ve seen recommended several times.
I brought my HDV footage into Shake and deinterlaced and squeezed it down to anamorphic SD, outputting uncompressed 8-bit. But after bringing this into FCP, I find that I can’t change the frame rate at which it’s interpreted (25). The clip properties allow you to change the anamorphic flag, but not the frame rate.
So what do I do from here? I want this stuff to be interpreted as 24P, and then I want do pulldown for NTSC so I can mix it with some regular interlaced 29.97 stuff. I DON’T want FCP doing any funky 25P-to-24P conversion first.
Any help appreciated.

Use the cinema tools “conform” option to conform to 23.98fps.

I’ll give that a shot.

Try FCPs Tools > Conform 25 to 24 menu item. Maybe that’s what you need.
23.98 is for NTSC 29.97 material made into 24.Neil

My intent is to make a progressive DVD to test the “film look” of deinterlaced 50i footage. I set the rate at 23.98 and then put the stuff into a 29.97 FCP timeline with some regular 60i stuff. The result looked a little stroby. FCP should’ve just done 2:3 pulldown, but knowing FCP, there’s no telling what it actually did.
I just made a 23.98 timeline, plopped the stuff in, and now I’m running it through Compressor to put on DVD. We’ll see what that looks like.
I seem to have found a bug in FCP during the process. When placed in a 29.97 timeline, the “conformed-to-23.98” footage and its audio lined up fine (except for the drift caused by the 25-to-24 slowdown). When the same clips are placed in a 23.98 timeline, the video ends at a different point and can’t be dragged out to show the whole clip, and the audio is way out of sync.

FCP drops and duplicates frames. It does not add 3:2 pulldown. If you want to do that, try my Standards Conversion which does that great.

That should work. I’ve made many 23.98fps DVDs that way and it’s great.
