Yearly the iPhone will get an increasing number of “professional” in terms of video as Apple unlocks extra superior features. This 12 months, the brand new professional choice was the flexibility to shoot ProRes on the iPhone 13 Professional. That’s a fairly vital improve contemplating it’s along with 10-bit HDR recording from the final era. Whereas ProRes is objectively higher, there’s nonetheless a query of whether or not it’s value utilizing.
Nicely, ZY Productions thinks so, and if you’re critical about video ought to all the time shoot in ProRes. If you wish to know why and the way it compares to the extra compressed choices you need to test this out.
The 2 opponents for codecs on the iPhone are HEVC and now ProRes. Each (when Dolby Imaginative and prescient HDR is turned on) will document in 10-bit. Nonetheless, HEVC will do shade sampling at 4:2:0 whereas ProRes unlocks 4:2:2. Small, however good. In some scenes with loads of colours the ProRes recordsdata will maintain on to paint higher and so they present an instance of this.
Audio is one other small tweak as HEVC data at 44.1 kHz and ProRes data at 48 kHz. One other small factor however makes a distinction.
One factor to dig deeper into the iPhone’s ProRes performance is precisely what taste of the codec it’s providing. Nicely, it’s straightforward to seek out that it’s ProRes 422 HQ. That is typically a most popular codec for picture seize as it is extremely top quality and virtually lossless. It is usually designed to deal with critical shade correction or grading.

When put into real-world exams, when you might have one thing like an underexposed clip you may simply see that HEVC begins falling aside a lot sooner. This comes at a price, nonetheless, as 422 HQ is large, so maintain that in thoughts. A minute of footage in ProRes is about 6 GBs. File sizes will result in longer switch speeds, restricted body charges to 30p, and require extra storage to benefit from them.
ProRes doesn’t use a really advanced compression scheme to avoid wasting the recordsdata. HEVC’s objective is precisely to compress as closely as attainable and has a really advanced technique of doing so. What this implies is that the less complicated ProRes encoding is lots simpler for computer systems to deal with and through enhancing this can imply smoother efficiency. It’s particularly noticeable on older computer systems or with a number of tracks taking part in on the identical time.
Aspect observe, the brand new M1 Professional and Max chips even have devoted encoders/decoders for ProRes, so efficiency is even higher. The iPhone 13 collection can even be capable of play again ProRes recordsdata from different sources now that the A15 chip helps it natively.
In order for you the highest quality on your shoots you need to completely shoot in ProRes. Even whether it is simply utilizing the iPhone as an additional angle for one more shoot, utilizing ProRes will enable you to afterward because the footage is simply as straightforward to make use of in your laptop as your common capturing.
