Exporting FCP to AE problem
by Craig Swanson on Sep 23, 2008 at 9:06:37 pm

After exporting an image sequence out of FCP I'm having trouble with my frame rate in after effects. I have footage with 32 frames but it shows up in after effects only at 26 frames. It's probably something stupid but I think I had all the bases covered.

My settings for the FCP tiff export is 23.976. After the export I check and see I have 32 frames. I then import into AE and interpret my footage at 23.976. Comp settings are 23.976. but the footage only shows up as 26 frames. Anyone have an idea I can try out?

The reason I'm using a tiff image sequence is because I'm batch treating the footage in illustrator before bring into AE.

[Craig Swanson] "My settings for the FCP tiff export is 23.976."

Where is this figure coming from? Is it the frame rate of the footage in FCP, the FCP timeline, or someplace else?

And do the frame rates of the footage and the timeline match?

Dave,

when I export the tiff sequence there is a box to enter the frame rate. I enter 23.976. My fcp sequence setting is 23.98 (prores hq). I also tried 23.98 for my tiff export but get the same issue.

Well, it sounds like there's a frame rate mismatch going on someplace in FCP.

At 29.97, 32 frames is a second, plus a couple of frames.
At 23.98, 26 frames is a second, plus a couple of frames.

It's almost like you shot some SD footage at 24p and didn't remove the pulldown before you put it in the timeline.

Dave,

I'll investigate to see if there is somewhere that 29.97 got into the mix. Original footage was shot on the red one camera at 23.98. I transcoded to prores at that frame rate and thought I used it throughout the process but it looks like that wasn't the case.

It's worth a look, but you could be right that it's some still-unknown Bad Thing going on.

Quick question: why a tiff image sequence? Instead of a Animation QuickTime file which is basically a tiff sequence in a QT wrapper.

cheers
