First I select a piece of video clip (MP4) which is cut in Premiere Pro CS6, then File -> Replace with after effects composition;
In AE, I choose Track in mocha AE.
When I try Paste mocha mask, only the first frame of the mask pastes. When I paste only the data to the composition, nothing changes at all. I paste the data in a text file to find that the numbers are relatively the same.
I know there are many similar asked questions, but no answer really helps me. I already checked Frame rate and in-out points settings. When I export video file in Premiere (without using "replace with ae composition") before tracking, everything works fine.
