If I have all of my video on an external hard drive, is there a way to 'point' iMovie 08 to that drive so that I can create projects and edit and save without the footage (aside from the final project footage) being saved on my internal drive. For example, I had a very long video on my internal drive. I created a 2 minute project and then moved the long video from my internal drive to my external. But the project wasn't accessible after this. I would like to store all of my video on the external drive, connect it when I want to create projects and edit, and save the projects on my internal drive. Is this possible? If so, how? Thanks.
