Are you planning to upgrade to the iPhone 16

First off, I'm pretty sure that the latest Apple Final Cut Pro now can do 3D because of their recent venture into Spatial 3D video.
It does work with 3D video but you still have to convert what you shoot on the iPhone and the Vision Pro as it won't ingest the files directly.

Apple has apparently registered the "later this year" trademark to cover much of what they promise of late.
So that is what I meant.
If you meant FCP, you shouldn't have said Adobe Premiere. ;)
 

iOS 18, what did you think?
