Got a head scratcher.

I imported a c4d project of a cell phone turning into AE CS5. I subbed out a plane for a piece of video, so the video is now on the cell phone. It works great.

I pre-comp that and now when I step through it, the video goes off time and doesn't stick the the phone anymore - it's off by a couple frames. I go back to the the pre-comp and it's perfect.

I went back and changed all the plane tracking keyframes from linear to holds thinking there might be something inbetween thats causing it, but did no good. Other similar files seem fine, but this one is different.

I could probably pre-render the pre-comp and it would all work out, but I'd rather not.

Any ideas? No time re-mapping is involved. Much thanks..

Hi there,

The only thing I can think of off the top of my head is that the frame rate for the comps may be different and should be the same? Also, Collapsing Transformations may cause some issues if there are further timing changes in the parent comp?

Hope this helps,

Make sure your comp frame rates match your source sequences. Most likely this means 30 fps although you can change the interpretation of the sequences to match the comps if you like. Just make sure they all match!

That did it- one was 30, the other 29.97.

Much thanks!
