Apple‘s October 30, 2023 Event closed with this end credit: “This event was shot on iPhone and edited on Mac.”

That would be filmed using the iPhone 15 Pro Max with the free Blackmagic Camera App and Apple Log. Plus edited in Premier Pro and then graded and finalized in Davinci Resolve.

michael tobin adds further insight and commentary:

My take: Of course, now Apple has to film everything they do like this!
