Normally when I work on an iMovie project, it has me import videos. This means that if I already have 5GB uploaded somewhere, and I import these videos in iMovie too, I now have at least 10GB of data that needs to be stored. As a result I have to come up with a hacky solution for creating lightweight backups.
I'd rather keep the videos separate and have iMovie just reference them.
E.g. instead of:
iMovie Library (5.1 GB) Video 1 (3 GB) Video 2 (2 GB)
I'd rather have:
iMovie Library (0.1 GB) Video 1 (3 GB) Video 2 (2 GB)
How do I use a video in iMovie without having to import it into my library?
Final Cut Pro has two settings that allow you to do this.
