Hi folks. Newbie to the mac world here. I'm debating whether to go with the Imac of the Mac pro to do some amateur photo and video editing with my new Canon HF 11 HD camcorder. I have NEVER worked with video before and I'm a little nervous pulling the trigger after visiting several Apple stores. I've heard some nightmares about editing high definition video in the AVCHD format. I guess I'm asking this.....is editing with AVCHD possible with an IMAC? Are the new 24inch IMACs going to be power enough? Would you recommend a powerful Mac Pro instead? Do you see any issues with the AVCHD format? Again, I'm a rookie with the video and have no idea what I'm getting into. Thanks for your time!
