Think I might not have had a good answer for a friend asking a favor. Friend had a vertical video that needed to be rotated horizontal. Most messing with video I've done has been transferring old stuff from VHS to DVD, in a machine made for that purpose, then condensing the DVD and uploading the video to YouTube... and it's been a few years since I've done even THAT! I mostly just mess with still photos on the computer, and occasionally rip old audio cassettes and LPs. Haven't even SHOT any video since that last Sony MiniDV camcorder died about seven years ago.
