I just got a digital video camera and made some home movies of my kids. It seems for every 3 minutes, I use up about 500 mb of disk space. This seems a little high to me. I have two seasons of the office (10 episodes a season x 20 or so minutes per episode) on my ipod and that only takes up 20 gb. Does anyone have any pointers for minimizing disk space with video? If not, does anyone have a recommendation for an external hard drive for an iMac? Thanks.
