I have tried refreshing rendered clips, re applying the effect.
My main background video was the whole screen plays at 3/4 screen and the 2nd crooped clip is missing the top portion of a rotated clip.
This is now a couple of hours later. 2 edits I have been able to fix but the 3rd one is still playing up. The clip is 4 minutes long so after checking it 20 times for a 4 second clip is taking some time.
Some how the clips re set again. So this is a screen shot of the 1st clip I am working on...
