Ok, so I've been recording some videos in Photo Booth, and of course all of the videos come out in the mirrored format. I'm wondering if there's a way to flip it horizontally so it looks normal. It creates it as a .mov file, so does anybody know of a program that horizontally flips .mov files? (or .mp4 for that matter. I can convert it). Thanks!
