Here's what I got: Macbook standard 13" iMovie 08 I'm looking to buy an HD Camcorder, of which I will do light editing of my footage in iMovie. I've heard I should stay away from Sony cameras. My debate is a camcorder with a hard-drive, sd card, or tape. I would prefer a hard-drive as I don't want to mess around with tapes and cards, but what about these AVCHD files that balloon in iMovie? I don't want to plug up my system with massive files that need simple editing. Can someone explain these files to me? And do I have to burn multiple dvd's to store these massive files in HD? Please help with any thoughts on generating the best/fastest workflow between an HD camera and iMovie 08.
