Consolidate projects and events in iMovie on Mac
In the course of creating a movie or trailer, you might use clips and photos outside of your library, especially if a storage device that contains media or iMovie libraries is attached to your Mac. If the media in a movie, a trailer, or an event is located outside your iMovie library, you can consolidate all the media in one location (either on your Mac or on a connected storage device) by copying the media to your iMovie library.
