I have a video I took while I was riding in a car. I want to crop out the bottom portion of the clip so as not to see the car. I can easily crop the bottom portion out, but I want to vertically re-center the cropped image in the middle of the frame. Is this possible? Right now the resulting video image sits on a large black space kind of like an unbalanced "letterbox" effect. It's distracting to me. I tried playing with the zoom to accomplish the same thing, but I don't like the way the zoom appears to stretch the image to fit the space vertically. Is there a way to constrain zoom to maintain the same height of the original space but relocate the image, perhaps? Thanks in advance.
