I tried a search on this but had no luck. I assume this is basic but I can't figure it out. Can you have two tracks that one uses the left half of the screen and the other uses the right? I have a photo montage of a bride and groom throughout their childhoods and I want to put their pictures on the screen side by side as they grow up. When I try the pan crop it is hard to get them to equal sizes (the two sides of the screens). Also, is there a way to crop a still image, and then move the cropped portion to one side of the screen? When I try this the whole photo moves. Thanks for any help.
