My daughter takes a lot of videos with her iPad. She has maxed out her iCloud storage, so we need to clean some up (deleting from Photos, maybe archiving to an external hard drive).
Unfortunately, some of them are included in dozens of iOS iMovie videos that she would like to keep. If I just delete the original footage, the iMovie videos will break. (Exporting the iMovies would preserve the final product, but she wants the iMovies to remain editable.)
What's the best way to identify the videos that are safe to delete, or otherwise preserve the iMovie videos? Transferring the footage directly to iMovie would be ideal, but doesn't seem to be possible (videos are linked, not embedded).
My best answer at the moment is a tedious process of manually identifying the videos to keep, one clip at a time. For each clip, we have to watch it and, by trial and error, figure out which item in the Photos library matches. Being able to directly apply a "Favorite" to a clip from iMovie, or even being able see the file name, would be a huge improvement.
