Apple iPhone 12 contains new features such as 5G and a plug-in system for MagSafe accessories . But perhaps the most technically impressive addition is the ability to shoot and edit 10-bit HDR video in Dolby Vision.
So what is Dolby Vision and why should you care?
Why is Dolby Vision a big deal?
Dolby Vision is a proprietary HDR video format. HDR stands for high dynamic range and HDR video contains much more information than standard dynamic range (SDR) video. A camera capable of capturing HDR video records more information about a scene, including a greater variety of rs colors and more visible details in highlights and shadows.
To enjoy the benefits of videoHDR, you need to view the video on an HDR screen. The same is true for Dolby Vision because it is a proprietary format. Not all HDR monitors and televisions are compatible with Dolby Vision content, but the format is slowly gaining traction.
What makes Dolby Vision special is its use of dynamic data. Unlike HDR10, which is an open format, Dolby Vision uses dynamic data to map frame by scene or frame by frame. This improves on HDR10 by providing the screen with more information on how to present the scene. Dolby Vision even takes the capabilities of the display into account when mapping video for more accurate reproduction over a wide range of displays.
Smartphones have already implemented HDR recording, including models from Sony, LG and Samsung which favor their own HDR10 + format. Apple is the first to roll out support for Dolby Vision in un mobile handset or standalone camera, as the process normally requires adding Dolby Vision data in post-production.
Which makes the implementation of Dolby Vision on the 'iPhone 12 so impressive is the amount of computing power required. IPhone needs to capture and process camera sensor data, record Dolby Vision data, and record it in real time. This adds to the overhead of running the operating system and other things associated with being a phone.

Update Apple's implementation of Dolby Vision on iPhone 12
The iPhone 12 (starting at $ 699) and its mini variant will be able to record Dolby Vision videos in 4K at 30 frames per second. If yougo for the more expensive iPhone 12 Pro (starting at $ 999), you will get Dolby Vision capture in 4K at 60 frames per second. This is due to the additional RAM of the iPhone 12 Pro since both smartphones use the A14 Bionic system on chip.
The A14 Bionic is the most important piece of the puzzle that led Apple to adopt HDR recording for the first time. Don't expect to see Dolby Vision or any kind of 10-bit HDR recording added to older devices via a software update.
The iPhone 12 has an OLED display. 10-bit capable of 1200 nits peak brightness, which is brighter than most OLED panels used in monitors or televisions . If you are recording in Dolby Vision, you will need a Dolby Vision-compatible display to watch your footage on after all.
Compressing Dolby Vision capture in an iPhone is not easy ll feat. Outside of smartphones, 10-bit shooting requires an expensive mirrorless camera like the Sony A7S III ($ 3,499 MSRP) or Panasonic GH5S ($ 2,499 MSRP), along with whatever lenses you want to use. You must use logarithmic image profiles like Slog3 (Sony) to produce a "flat" image that can be noted in post.
Next you need to learn how to rate HDR images for the format you are targeting, which for most non-professionals would be open standards like HDR10 or Hybrid Log Gamma (HLG). This involves working with large files, so you need an editing station that can keep up. You would also need a decent HDR-capable monitor that can hit a reasonable maximum brightness to see the fruits of your labor.
The iPhone 12 eliminates a great deal ofrtie from the pain of this process and makes it possible for anyone to shoot in Dolby Vision. This has never been done before and required Apple and Dolby to come up with an appropriate workflow to record both video and data in a user-friendly manner.
The iPhone 12 n It's not just a camera but also a video editor , with support for editing your HDR videos using the standard Photos app. You can even apply filters and tweak the settings to get the look you want.
Of course, the iPhone is still limited by its form factor, small sensor, fixed lens, limited lifespan battery and a processor that is not. is not only dedicated to video capture.Don't expect Hollywood production levels, but expect a big leap forward in video quality, color volume, and peak brightness compared to SDR video.
Are There Any D Returning to Dolby Vision Recording?
Dolby Vision is gaining ground as an HDR video format, but it is not widely used. Compared to its closest rival, HDR10 +, Dolby Vision enjoys relatively wide support among TV manufacturers. The only major brand that does not support Dolby Vision so far is Samsung.
For many people, the iPhone 12 will be the only Dolby Vision compatible device they own. This would limit the splendor of Dolby Vision ride-on videos on the iPhone 12 screen. It may also hamper the usefulness of these HDR videos in terms of sharing.
Dolby Vision video is limited to Dolby Vision displays. If you've ever stumbled across HDR-only video onr an SDR display, you will know how washed out and weird colors can be. If Apple can master the “squash SDR” for sharing Dolby Vision videos in SDR format, it will give the format wider appeal and more flexibility.
There is also the small problem of disk space. 10 bit recording means you capture a lot more data. Even with more more efficient video codecs like HEVC (H.265), Dolby Vision videos will take up much more space than SDR video. You are going to need an iCloud plus plan large or more storage space on your iPhone.
More data means more crackles from the A14, in addition to saving data to on the fly. Recording in Dolby Vision will burn battery life faster than HD video.tandard. f production regarding editing and processing of files.
Even viewing your Dolby Vision videos will cost more in terms of power because the screen has to work harder to render the highlights.
Will Dolby Vision become “mainstream”?
There's also a question of how far the iPhone 12 audience will embrace Dolby Vision, at least initially. Dolby Vision televisions have only been around for a few years. If you don 't have one, how likely are you to save anything in the format?
The same question could have been asked a few years ago when Apple added support for 4K capture. How many iPhone owners have manually changed to the higher resolution format under Settings> Camera? After all, Apple never "forced" the change in an iOS update.
Although the technical feat accomfold by Apple is impressive, stepping back from the hype reveals a somewhat niche feature that may not be so valuable to the average iPhone owner in the short term. For creatives, videogr aphers, YouTubers, and people who love to play with video, Dolby Vision makes the iPhone 12 a compelling buy. For everyone else, 5G and MagSafe may be more appealing .
But HDR video will become more mainstream over time over the next few years, as more screens and smartphones implement it, with or without Dolby's proprietary technology. Qualcomm showcased "professional grade" HDR10 + video using a Snapdragon 855 system on chip earlier in 2020 , with Dolby Vision support available on the Snapdragon 865. Samsung has supported HDR10 + in select Galaxy models since 2019.
The addition of Dolby Vision to the iPhone 12 is a victory for HDR video in general, pushing the format forward . It’s also a victory for Dolby, which appears to be in a better position than ever to win the emerging war of HDR formats.
