List of UHDs that contain HDR10+

That sounds like the most likely scenario, yeah.

There's still the small matter of actually adding HDR10+ to the UHD Blu-ray specifications though. As easy as it may well be to do it still needs, y'know, actually doing.

I wonder if Apple will get behind HDR10+ and add it to ATV 4K.

Hopefully in a few years we can get to TVs that can sustain 4000 nits so this dynamic metadata band-aid is not needed anymore. Dolby Vision still has a slight technical advantage in that the video is 12-bit, but that might not be that big of an advantage.

[Geoff D]

If you've got a TV that can get nearer 2000 nits then it hurdles a lot of HDR10's mapping issues in one fell swoop, never mind 4000 nits.

[SkyAntoine]

I'm going to keep this in perspective. Of all the people I personally know with 4K TV's I'm the only one with a UHD player or that watches UHD content.
Everyone else in my family or friends are probably running their programming off coax cable.
I want the best possible picture, but I'm happy now with my PQ. Not sure how much more happy I can be with HDR10+ especially if it means upgrading EQ.

Batman Begins without that ****ing DNR I'd be all over like white on rice. As for HP, considering how many TVs out there have shit the bed when to comes to mapping the extremely bright highlights then a dynamic metadata option wouldn't be the worst idea in the world.

The only problem of course is that it still doesn't benefit the current user base who lack HDR10+ capability.

List of uhds that contain hdr10+.... yep this is easy to compile.

ZERO... lets hope it stays that way.

Good luck with that.

Yes, Dolby should save us some time and drop out now as will be the inevitable result after going up against open standard HDR10+

[Vangeli]

I'd like to see Vizio make a 1000-nit display this year because right now their mapping of highlights has never caused issue for me and while their current models are half that, the trade-off is that they don't dip to 100-nits at 100% coverage like OLED, nor do they dim over time with sustained brightness like a Samsung or some Sony models. Consistent brightness performance across the board; I like that philosophy and hope they can do that with double the nits this year.

Maybe double the FALD zones too while they're at it.

Does anyone know why one disk can't be authored with both dynamic HDR formats?

Not at the moment. Maybe never. The base layer is currently always HDR10 on disks. Streaming is a different story.

I have a Samsung 4k tv, which means that it supports HDR10+, but not Dolby Vision. I also have a lot of UHD Blu-rays with Dolby Vision compatibility. How much will the difference be when playing either HDR10+ content and Dolby Vision content on this tv?

I understand that, but I'm asking why, not if, three formats can't be a thing.

[Vangeli]

Dolby Vision at the moment mostly means less banding on some discs. HDR10+ won't change that given it's still 10-bit vs. the 12-bit of DV.

When we have true 12-bit displays the difference may be more noticable.

Of course, they can be. But the current standard states you can only have a base layer + another layer. HDR10 is the base layer (mandatory). And HDR10+ (Plus) is NOT among the possible "other" layers, currently.

Ideally you would want HDR10+ to be the base layer and DV to be the optional one, but not sure if that is possible without patching all 4K players.

I don't know why, but given how much of an arseache it is to encode Dolby Vision onto disc already (https://forum.blu-ray.com/showthread...r#post14525078) I'll hazard a guess and say that the DV-on-disc authoring tools - only having been set in stone fairly recently - would need to be revised again and that might be a step too far. The HDR10 layer is a big part of the DV encoding equation so whatever dynamic metadata HDR10+ has it might need to be injected as part of that DV encoding/authoring process.

Also, the HDR10 layer is itself an offshoot from the DV master on this base + enhancement layer system, so in order for the HDR10+ metadata to be derived you'd have to do your DV grade, then the 709 trim pass to create the dynamic metadata, then use that metadata to generate the HDR10 layer, and then run that HDR10 layer through whatever grading tool or plug-in you'd be using to generate your HDR10+ metadata. Not impossible but certainly time-consuming, having to do a master grade and then two separate trim passes to create the two sets of dynamic metadata - but then didn't someone hint that the two systems parse the metadata in very similar ways (albeit not down to the frame by frame level on HDR10+) so perhaps they could simply convert the DV metadata into HDR10+ metadata after all?

Simple answer: I dunno.

Sorry, Samsung will not support DV for your current tv. Sammy doesn't like the DV royalty fees, even though LG, TCL, Sony and Vizio don't mind.
So, you have a 2017 model, right?
