This app is amazing for YouTubers

I love this app and I use it for every video I need to edit. But..... I dont have a lot of storage soo.... I make the vids with my camera and then I move them to iMovie and edit. But when I need to take the whole movie to my camera roll, I cant bc of my storage is too full. So I delete the vids but then it says "missing pieces" and then I cant get my vid :(. So I would like if iMovie can fix it maybe. Bc I cNt upload and I need to upload on certain days. Thank u.
