I'm attempting to composite Video Clip A (960 x 540) into a picture frame within Video Clip B (1920x1080).
I want to use the Perspective Corner Pin in the Tracker options and it works fine when applied directly to clip A.
However, clip A is shorter in duration than clip B and I want it to play until the end of clip B. So I duplicated clip A a couple of times so it repeats enough to fill the duration and then pre-composed the multiple copies of clip A into a single layer. When I apply the tracker info to the pre-comp the clip B is much smaller than it *should* be:
Could anyone explain where I'm going wrong please?
