23.98 interpreted as 29.97? Help!

I have a bunch of footage that was shot with 24PA and imported with the pulldown removal. I can see in Quicktime that the pulldown is indeed removed, and other applications (such as After Effects) treat the footage as 23.98 fps. However, FCP seems to think it's shot at 29.97, and, as a consequence, I get a strange stutterring effect.

I found a workaround in that I can re-export the footage, and then it is recognized properly when re-imported into FCP, but it's rather time-consuming. Anyone know of a better way to deal with this or what's going on? Thanks!

The reason that FCP thinks that your footage was shot at 29.97 is because it was. The signal that gets written onto the tape while shooting is at 29.97. Then when you have it in your 23.98 timeline in FCP after importing it with the advanced pulldown removal it should be 23.98 without any rendering. I'm not sure what the strange stuttering effect could be. Other than when you watch the footage in the capture window it does sometimes stutter on the jutter frame. If you see that same stuttering while playing your clips from your timeline then I'm not sure what it could be. Just make sure your settings are right.

You have to run your stuff through Cinema Tools.

Batch Telecine your captured footage to 23.98

Spencer, I ran into this problem awhile ago and it was bugging the heck out of me. Finally found that when I let FCP capture until the tape stopped, it brought the footage in as 29.97. But if I stopped it before the end of the tape, or used batch capture to specify that it stop before the end of the tape, then everything came in fine.

Bottom-line: Don't let it capture until there is no more, you have to stop it before it hits the end.

HTH,

This has happened to me before. I was able to click on some of the clips and tell it to "remove advanced pulldown" under tools. This will convert it. Or at least, it did it for me for most of the clips. For some reasons, there were a few it couldn't remove the pulldown.

Kyle,

The same thing happened to me. Whenever FCP says it can't remove the pulldown from footage you KNOW was shot 24pa, that means you have at least one "long frame" in the clip, usually on the beginning or very end of the capture, that is screwing up the cadence of the pulldown removal. Find the long frames and remove them--then try it. I got all of my footage cleaned up and pulldowns removed this way.
