One of the novelties of the iPhone 13 Pro is the possibility of capture video with ProRes, Apple’s video codec system that maintains higher image quality and improves editing performance. It is a function specially designed for those content creators looking to record professional videos with a smartphone. The function in 4K, however, not available in all storage variants.
The iPhone 13 Pro, remember, come with versions of 128 GB, 256 GB, 512 GB and 1 TB of memory. All these variants are capable of recording and saving those videos captured with a resolution of 1080p, 30 fps and with ProRes activated. However, those users who want to record video with these characteristics, but in 4K quality, should opt for a internal storage that goes from 256 GB, given that Apple has confirmed that the model with 128 GB does not support such a high resolution.
The iPhone 13 Pro and iPhone 13 Pro Max support ProRes video recording at 1080p 30fps with the 128GB storage option and up to 4K with 30fps on the 256GB, 512GB, and 1TB storage options.
Mention Apple in the Press release on the iPhone 13 Pro.
Recording 4K video with ProRes could fill up your iPhone 13 Pro’s storage
The company has not confirmed a reason why the ability to record 4K video with ProRes is not available in the base storage version. However, it is most likely due to large size of recorded clips with the aforementioned video encoders and decoders.
The ability to record video with ProRes also seems to have been the reason why the iPhone 13 Pro have more powerful graphics compared to the cheaper models of the new family. While both include the same A15 Bionic chip, Apple has added a 5-core GPU in the higher models, while that of the iPhone 13 is 4-core. The ProRes function, which can be configured through the system settings, will arrive in a future update of iOS 15, as confirmed by the company during the presentation event.
