'There's no realistic chance all of that content will get remastered from scratch': Dolby Vision 2 will come to more titles than you might expect, thanks to an automated process — but there will be two key creative-led features that aren't automated

Dolby says that Dolby Vision HDR movies can be upgraded to Dolby Vision 2 using an automated process based on the existing mastering information
This means support may be more widespread than expected, since apparently it will be relatively low-effort for streamers to achieve
The Authentic Motion and Precision Black features will be excluded from this, because Dolby says they they require human judgment to get right

If you're wondering where all the Dolby Vision 2 media is going to come from, we've got good news: it's already here, at least partly. Dolby Laboratories told me that it's created a process that can upgrade existing Dolby Vision media to add most features of the new HDR standard using an automated process based on the existing mastering data — and there are only two key features that are excluded, because they're areas that depend on new input from creators.

With Dolby Vision 2 arriving on TVs from this month, I caught up with Dolby Laboratories' director of business strategy, Jonas Klittmark, to find out the details: what it could do for 4K Blu-rays, what benefits it'll bring to streaming and most importantly of all, what to watch.

One of the biggest concerns with Dolby Vision 2 is that creators just won't be inclined to master video for it when it doesn't have widespread support — but it's unlikely to get widespread support if there's no content. But it turns out that existing Dolby Vision masters can be adapted to use many of its features without being reworked.

"There is a bunch of new features in Dolby Vision 2 that don't rely on new content at all," Turkstra told me. "Because you already have all the Dolby Vision content in the world... the streaming providers will have more to say about this later, but the existing Dolby Vision library will start to get converted and the new metadata for Dolby Vision 2 will be added."

Klittmark estimates that there are around 33,000 movies and TV show episodes available in Dolby Vision. "There's no realistic chance that all that content is going to get remastered from scratch," he says.

"The cost of doing that is just astronomical. So what we're offering instead is a semi-automated way of doing it where we're using modern techniques such as machine learning to assist in the creation of the additional metadata that's needed to make the most of Dolby Vision 2."

He elaborated that "many of the features, including the image engine, including the new version of LightSense, the intensity control, the pro settings, and sports optimization, all of those features can work through a combination of existing metadata."

That metadata is based on existing mastering data, and as will all of Dolby Vision 2, the next-gen data is in addition to the existing data; it doesn't replace it, so the automation won't affect the visuals of, or compatibility with, TVs that have the first generation of Dolby Vision but not the second.

What Dolby Vision 2 features can arrive automatically – and what ones can't

The two exceptions to the automated upgrade are Authentic Motion, which enables creators to control how strong your TV's motion processing is applied on a moment-to-moment basis, and Precision Black, which is designed to address dark scenes that looked great in the creators' mastering suite but appear too dark on TVs.

Klittmark said: "Authentic Motion is an example of a feature where it's just too sensitive. I don't know if you've been following the fairly polarized debate about motion that has been playing out over the years, with Tom Cruise making public service announcements, and things like that. That feature is so sensitive that we don't generate that metadata, it has to be manually authored."

I've seen Dolby Vision 2's Authentic Motion in action, and I think it's a great addition — it means that judder can be removed in scenes that need it, but motion smoothing can be deactivated in scenes that don't. I suspect that actually it probably could be automated to good effect, but as Klittmark says, I don't thing anyone would really trust that, so it's best that Dolby is leaving that to humans.

When it comes to Precision Black, Klittmark says this can't be automated because in order to get it right you need to know all about the creator's environment: "how dark was their ambient light, what kind of reference monitor were they using, et cetera... that cannot be speculated about or generated, so that needs to come manually from the creative."

When is Dolby Vision 2 not Dolby Vision 2?

I asked if this meant that movies might be labelled as supporting different Dolby Vision 2 features, but Klittmark says the firm doesn't want to make things complicated in that way.

"We've taken the simplest possible approach for consumers' benefit, which is that all the content is going to be Dolby Vision. There is no asterisk. There's no 'Dolby Vision 2' content, for example. There's no 'Dolby Vision 2 Max' content or anything like that. It's just all Dolby Vision content," he says. "And that way, it's very simple for a consumer to know what to look for. If you see that the content is in Dolby Vision, then you are getting the best experience you can get with that particular movie or whatever it is you're looking for."

I think this makes sense — your TV will be labelled as Dolby Vision 2 or Dolby Vision 2 Max, and potentially could tell you which features of the format are active, but when it comes to browsing the library, it makes sense to simply use the Dolby Vision logo to indicate that you're getting as many advanced features as the service has added, regardless of what they are.

Klittmark pointed out that this would be new to Dolby Vision 2, either. "The original version of Dolby Vision had tons of features in it, and not all creatives chose to use all of them all of the time. And there was no way to know that. And that's essentially a choice up to the creative. Which of the Dolby tools do they need do they feel like they need to use for which content? We leave that decision to the creative," he said.
