One of the main reasons I bought a Mac was easy handling of my HD videos. I obviously was ignorant on the limitations of iMovie. I've learned to live with all of them except the darn multiplication of file sizes. A two-hour HD video that takes up 35 gigs on the camera is taking up 133 gigs on my hard drive when imported into iMovie. At that pace, my Mac hard drive will be full in no time and even my external drives (2 1TB drives) won't keep up for long. From what I've read, I fear there's no good solution for this in iMovie, which is a real bummer. Please tell me I'm wrong. Would the situation be dramatically better if I splurged on Final Cut Pro? Can that program work with my video files without quadrupling their size on my HD? Thanks in advance for any wisdom you can offer.
