Questions

Which iPhone do I need?

An iPhone with iOS 18 or later. What you can record, like Apple Log, ProRes and frame rates up to 4K at 120 fps, depends on your iPhone.

Do I need an SSD?

No. HEVC 10-bit records on the iPhone. ProRes and ProRes RAW record only to a USB-C SSD. With no drive, the app records HEVC and tells you.

Does it upload my clips?

No. Clips stay on your iPhone or your own drive. There is no account and no cloud.
