Imovie wont let me add my 4k video
Im trying to import my movie clip that i shot on my iphone 15 to the imovie app. The other clips i took not in super HD show the plus sign for me to add no problem but the HD one only shows what looks to be a play arrow or three dots I think to like download it to a cloud. I don't know how else to import it, its a 12 min video can i split it somehow before i add to imovie or change the resolution?
iPhone 14 Pro, iOS 18
