I have a project with three compositions where each layer within said compositions are the identical source file. It is a map and after I render all three of these compositions, I'm going to put them together. So obviously, I want the compositions to line up properly (be the same dimensions.) My problem is that one of them is not the same as the others (it cuts off where the other two don't.) How do I make it so they do line up? I don't want to have to try and match them up myself..
CTRL-ALT-SHIFT will put your clip full frame in the center of the comp. If that's not exactly what you want, try doing the same shortcut, then select all your layers and size them to where you want them.
