Apple’s iPhone 16 event is in three days, and today, there’s a new leak (from “reliable sources” speaking to 9to5Mac) that claims the Pro version will support the ability to record video in 4K at an impressively smooth 120fps. According to that same source, iPhone 16’s rumored new camera trigger button will support changing from the default camera app to a third-party one.

The article goes on to state that the 4K 120fps video can be shot up to ProRes quality when used with an external SSD. Apple is also reportedly improving its photo mode video recording shortcut QuickTake to shoot in 4K quality instead of 1080p. Other features like JPEG-XL image format support, the ability to pause a video recording, wind noise removal, new special video modes, and improved ML image processing for skin tones are also coming. The sensors could support 8K video, too, but that feature might have to wait for a future iPhone.

As for the new Camera Button, which is apparently the internal name of the new iPhone side trigger, it will reportedly support slide gestures to adjust zoom or exposure, in addition to the soft and hard press support for focus and shoot. The button will use the same iOS 18 API that lets you replace the homescreen camera button with another similar app — Halide fans, rejoice!
