    So I recently ran into this issue and had a quick fix. I was wondering if anyone has a proper fix.

    I am doing a 3d motion track of some footage- then adding some C4D elements. I had to create a mocha shape roto for some foreground objects so they sat in front of the C4D elements.

    Everything was going fine- until i tried to export the mocha shape data to after effects. It kept coming in a little slower than the video with the C4D elements. It was the exact same clip, same size, same frame rate, eveyuthing was the same- EXCEPT I had a PNG image seq from C4D and I used my original vid file in mocha. However, they should have been playing back the same.

    I did a test and exported the video file to PNG seq in after effects because that is what I started with as my background layer in C4D. I re-imported the image sequence and the frame rate was off. The image sequence was plying at roughly 220 fps, while the original clip was 281 fps. I tried exporting at 24fps rather than 23.976- but I ended up with the same results. I played around with different export options and gave up. I did not want to redo all of the mocha roto work, so instead I did a time adjustment on the image sequences so they matched the original file and the mocha shape info.

    It was a quick and dirty fix and was wondering if anyone knows what the real problem was. I tried all of the main steps, from deleting plist files to creating a new after effects file to restarting my computer. This is bothering me because I know there is a proper fix. Any help would be great. Thanks.

    Hi there!

    Did you check your import settings in the preferences to see if it matches your frame rate?

    Just throwing it out there.

    Cheers.

    So that’s the solution to that mind-bender. That was the issue- I probably should have checked that. Thanks for the help.
