I'm using a single iMovie Library for my video project so that I can create versions easily.
Once I'm done with my project and have, say 10 different versions in there, I want to upload it somewhere (e.g. to Box) to save it for the future. Even though the duplicate projects for versioning don't create duplicate video files, it still contains a single copy of each video.
If I have 5 videos at 1 GB each, my iMovie Library is at least 5 GB big. My videos are already on Box.com, so adding the iMovie Library will take up an extra 5 GB that is not needed.
Is there a way I can back up an iMovie Library without having copies of the videos?
