How do I go about dumping my HDV or DV footage to my External HD? I'm using a Sony HDRHC7 connected by Firewire to my MacBook. My External HD is connected to the MacBook by USB. I only have 7-8 GB free on my MacBook so I'd like to do all the editing in iMovie from my External HD? Is that even possible? I couldn't find a preference for anything like that in iMovie. Any help is appreciated. Thanks. EDIT: Also, using iMovie I can't seem to import my footage in a smaller size. When I start a new project I select DV (I'm always filming in HDV though). However, from what I can tell it doesn't seem to make a difference regarding file size if I select DV, DV Widescreen or HDV 1080i when given the choice while creating a new project. I imported the same 20 seconds in ezch of those 'settings' and they all were the same size, about 230MB for the 20 seconds....how do I import as the smaller SD format?
