Rotating image/video about an axis within xy-plane in FCP Is it possible to animate a photo/video so that it continuously rotates about an axis within the xy-plane? For example, rotate it about the y-axis. I know how to regularly rotate a video (rotation about z-axis), and I know you can keyframe using distort with keyframe, but was wondering if there is a way to continuously have a shape rotating about a vertical axis. This would be like 3D-rotation.

For example, having the image of a card continuously "spin" vertically.
If you don’t want to use keyframes than it sounds more like a job for Motion or you might be lucky and find a plug-in for this behaviour. 
I couldn’t think of anything else than keyframes.
