Cropping and rotating in Final Cut Pro X
I'm using some still photos and putting them over a white background to create the look of snapshots with white borders. I've sized and placed them the way I want, including cropping the two sides of the white background (see attached screenshot).
What I want to do now is gradually stack three photos on top of each other, the first one without rotation, the second rotated a little in one direction and the third rotated a little in the other direction. But when I rotate them, the cropping changes so that the corners rather than the sides of the background are cropped (see screenshot).
I tried creating a compound clip with a still photo and the cropped white background, and then rotating the compound clip, but the same thing happened. Then I tried making a freeze frame from the compound clip and rotating that; you guessed it, it still changed the cropping on me. How can I get it to rotate without messing up my cropping?
