I've starting using the Ken Burns effect a lot. So easy in FCP X! One question: sometimes, I want to increase the size of either the stop or start, and I want it to just be increased proportionately. Right now, I'm pulling an edge, and then re-adjusting the frame over where I want it. Is there a way to pull an edge so all the edges grow larger (or smaller) rather than changing size and readjusting?
