It takes a ton of processing power to shoot 4K video at 60 fps.
We built A13 Bionic to deliver unparalleled speed and advanced machine learning. It’s what allows iPhone 11 to power through processor‑intensive tasks. Shooting 4K video at 60 fps in extended dynamic range, for instance, is like a firehose of information hitting the video encoder at once. Processing it would be a challenge for most chips. But A13 rips straight through it.
Think of video as a series of frames. Thanks to incredibly fast camera sensors, iPhone 11 is able to produce 120 frames per second, alternating between standard exposure and short exposure frames.
The image signal processor and video encoders analyse each of those frames in the moment to capture as much detail as possible. To take it even further, the Neural Engine uses real‑time machine learning to optimise the different components of the scene. For example, it might relight the person in the foreground, while reducing noise and enhancing colour in the sky. It all happens instantly and automatically.
Producing the highest-quality video in a smartphone isn’t easy. But thanks to the super-powerful A13 Bionic, you’d never know it.
