Here I show you why Final Cut Pro is not opening / importing your iPhone videos.
I took some video on my iPhone 11 and tried to import it into Final Cut Pro and no luck :( Would not import. I found a way so that new videos that I have taken will import.
Question is what about my old videos, can I change the format of those? This I'm still trying to figure out. Let me know in the comments if you have a fix for this.
Thanks
