How Apple Created a Custom iPhone Camera for ‘F1’ Leave a comment

You possibly can’t mount a cinema digital camera on a System One race automotive. These nimble automobiles are constructed to express specs, and capturing racing footage from the motive force’s viewpoint isn’t so simple as slapping a GoPro on and calling it a day. That’s the problem Apple confronted after Joseph Kosinski and Claudio Miranda, the director and cinematographer of the upcoming F1 Apple Authentic, wished to make use of actual POV racing footage within the movie.

If you happen to’ve watched a System One race currently, you have in all probability seen clips that present an angle from simply behind the cockpit, with the highest or aspect of the motive force’s helmet within the body. Captured by onboard cameras embedded within the automotive, the ensuing footage is designed for broadcast, utilizing particular shade areas and codecs. Changing it to match the look of the remainder of the F1 movie can be too difficult to be possible. As an alternative, Apple’s engineering crew changed the printed module with a digital camera composed of iPhone components.

The module seems to be nothing like an iPhone. It deliberately resembles the printed digital camera module, and Apple even needed to match the load in order that its model would not alter a automotive’s specs. The within, nevertheless, is totally totally different. (Apple gave us a peek throughout WWDC final week alongside an F1 automotive.)

On the coronary heart is an iPhone digital camera sensor powered by an A-series chip. Apple did not specify the precise sensor or chipset, however these have been used for just a few vehicles in actual F1 races all through the 2023 and 2024 seasons, so there’s an opportunity it was the identical A17 Professional and 48-megapixel major digital camera within the iPhone 15 Professional. It additionally contained an iPhone battery and a impartial density filter over the digital camera to cut back the sunshine coming into the lens, giving movie editors extra management over publicity.

Nobody expects an iPhone digital camera to carry out flawlessly at unimaginable speeds or excessive situations, so the engineering crew needed to contemplate this issue. They examined the digital camera module to make sure it might endure excessive shock, vibrations, and warmth—it supposedly surpassed the specs offered by System One.

The module ran iOS however had a customized firmware for the digital camera. The movies have been captured in log format with Apple’s ProRes lossless video codec, delivering footage that appears flat however offers the editors far more granular management to paint grade and match the visuals with the remainder of the movie. This practice firmware inevitably led to 2 new options within the iPhone 15 Pro: log encoding and assist for the Academy Shade Encoding System (ACES) shade workflow.

Since there aren’t any radios within the module, a customized iPad app was the one means the filmmakers might make on-the-fly adjustments to the digital camera. As soon as related through USB-C, they might regulate issues like body price, publicity achieve, shutter angle, and white stability. That is additionally the place they’d hit file to begin or cease recording. The footage captured with the module is sprinkled throughout the F1 film.
