I can't seem to find a straight answer for this. See attachments. I have a basic rectangle on V2. I put track matte effect on V1 with Matte mapped to V2. Looks fine. Simple rectangle mask effect accomplished. But I want to rotate the image track inside the mask, but the mask spins too. It does this if I do a mask in Opacity effect control too. How can I keep the track matte or mask to stay put while the image track can rotate/scale or whatever inside there?
