Probably be a good idea to post this in the Video forum. For multi-cam edits, you are looking at the right software packages. AVID may also have something good, but it will cost more. Final Cut Pro X, IMHO, is a forward looking program that is structured the way editing software will be in a few years. We all live with the fact that a lot of video editing programs have not caught up with the latest compression algorithms being used in camcorders, and we have to render the files into a compatible format before editing.
Only my opinion. It's worth what you paid for it. Your mileage may vary! ;-} www.dougwigton.com/
