Just started woking with iMovie. My first step is to convert all my analog tapes to DVD, via a MiniDV camcorder. My 1st project was ~15GB. Once I burn to dvd, is there a way to compress iMovie project for archive? My plan is once I convert all my analog tapes, I want to make a highlight dvd using clips from the various analog tapes, without having to grab the clip from the analog tape again. I have a 320GB external drive, but the projects are going to start to add up.
