How to create a scrolling picture-in-picture?
I know how to scale a clip and move it around to create a normal picture-in-picture, but I need something a little different. I've created an instructional video that's demonstrating written instructions. I'd like the instructions to scroll in a small window in the corner of the main video. The instructions are just a jpeg that I'd like to be longer/taller than the height of the inset window so I can scroll them just by animating the Y parameter. Any tips?
