Everything New in iOS 15.1 Beta 3: ProRes Video and Macro Mode Toggle for iPhone 13 Pro Users

Wednesday October 6, 2021 11:41 am PDT by Juli Clover

Apple today released the third beta of iOS 15.1 to developers for testing purposes, and the update introduces some new camera features for iPhone 13 Pro users.

General iOS 15

ProRes Video

Today's beta adds support for ProRes video capture with the standard iPhone camera app. It can be toggled on by opening up the Settings app and selecting the "Camera" section. From there, tap on "Formats" and toggle on "Apple ProRes."

ProRes capture is limited to 30fps at 1080p on devices with only 128GB of storage, but higher capacity devices can record in 4K. Apple says that a one-minute 10-bit HDR ProRes video takes up 1.7GB in HD mode.

Macro Toggle

To take macro shots, the iPhone 13 Pro models swap over to the Ultra Wide lens when the iPhone's camera gets close to an object, which some people do not like because it can be difficult to get a shot with the camera constantly swapping back and forth.

iOS 15.1 beta 3 adds a toggle to turn off Auto Macro, which will prevent the Camera app from automatically switching to the Ultra Wide camera for macro photos and videos.

The feature can be enabled in the Camera section of the Settings app by scrolling down and toggling off the "Auto Macro" option.

I would love to see more on whether 4K prores is essential over 1080.

I’d love to see anyone trying to get 4K ProRes videos, clocking at tens of gigabytes each, if not more, off of that USB 2.0 Lightning port.

So…they just don’t mention the file size for 4K? Like who cares about 1080p, I would like to know the max size per minute.

Quoting MKBHD, a minute of 4K ProRes video takes up about 8 gigabytes of storage.

Apple makes it clear and obvious ProRes 4K for 128GB devices is a marketing limitation rather than technical.

ProRes 4K = 6GB/min = 100MB/sec

Even iPhone 7 can write at 350MB/sec. With 128GB, ProRes 4K can store at least 15 minutes of video, but Apple has decided 128GB users shouldn't use this.

I mean, it’s not appropriate. I am real world your phone would max out and be full after just a couple of minutes. If you’re a person who actually uses pro res, or any cinematographer, you would never get a 128 device.
