I am curious how to do this here.
My issue is, I am using SD footage for an Avatar Music Video, and have a few parts where flashes will be in effect, but the issue is, since it is SD, and it will be played to 1280x720, it of course has the black bars on the side, but the flash carries over and flashes over the black bars as well. I don't want that. I want the flash to happen solely on the footage itself. How would one make this happen?
