Apple’s tech specifications for the smartphones state that in order to record 4K ProRes video on the iPhone 14 Pro and iPhone 14 Pro Max of Apple, a model with at least 256GB of storage is still necessary, just like it was with the iPhone 13 Pro versions that were released last year.
On models of the iPhone 14 Pro with a 128GB storage capacity, ProRes video recording is restricted to 1080p @ 30 frames per second. A model with a storage capacity of 256GB, 512GB, or 1TB is necessary to record ProRes video in 4K at 30 frames per second.
Apple’s press statement announcing the iPhone 14 Pro versions includes the following footnote:
ProRes video recording in the Camera app is supported on the iPhone 14 Pro and iPhone 14 Pro Max at 1080p 30 frames per second with the 128GB storage option and up to 4K 30 frames per second with the 256GB, 512GB, and 1TB storage options.
Because 4K recordings produce large files, 128GB versions of the software do not support 4K ProRes video recording. A one-minute 10-bit ProRes movie is approximately 1.7GB in 1080p and 6GB in 4K, according to Apple.
The iPhone 13 Pro models first introduced ProRes, a series of Apple codecs that can compress videos into smaller file sizes with “amazing image quality preservation.” According to Apple, ProRes is intended as the final delivery format for high-quality videos, including broadcasts, features, and commercials.
The basic iPhone 14 and iPhone 14 Plus still don’t enable ProRes video recording at all.
