Apple's iPhone 13 Pro and Pro Max models exclusively support a video recording feature called ProRes, which allows you to capture, edit, and share professional quality video. Here's how to enable it on your iPhone with the iOS 15.1 beta.
Aimed at professionals, the ProRes codec offers higher color fidelity and less compression, and it is often used for commercials, feature films, and TV broadcasts, which is testament to the high quality results that it can achieve.
A one-minute 10-bit HDR ProRes video takes up 1.7GB in HD mode. For that reason, recording ProRes video at 4K at 30 frames per second requires 256, 512, or 1TB of iPhone storage capacity.
In other words, if you have an iPhone 13 Pro or iPhone 13 Pro Max with the base 128GB of storage, you'll be limited to shooting 1080p ProRes video at 30 frames per second.
With that in mind, you can follow these steps to turn it on.
- Make sure you've updated your device to the iOS 15.1 beta by going to Settings -> General -> Software Update after downloading the appropriate profile from the Apple Developer Center or Apple's public beta website.
- Once your device is updated, launch the Settings app again.
- Scroll down and tap Camera.
- Tap Formats.
- Under "Video Capture," toggle the switch next to Apple ProRes to the green ON position.
With ProRes enabled, the next time you choose the Video mode in the Camera app, you'll see the ProRes indicator in the top-left corner above the viewfinder. If it's crossed out, tap it to enable the feature. The "Max Time" at the top of the viewfinder also tells you the maximum duration that you can record in ProRes, based on your iPhone's storage capacity.
Along with ProRes, the iPhone 13 Pro and Pro Max feature improved Wide, Ultra Wide, and Telephoto lenses with better low light performance, macro capabilities, Night Mode, Cinematic video recording for depth-of-field transitions, and Photographic Styles for enhancing images.
