Dunkirk 4K UHD (2017)

[brainofj72]

I will be very, very surprised if major US studios release ANY new movies on 4K without HDR at this point. I think everyone just expects it as one of the benefits of the format by now.

[Geoff D]

Yep, that too. I mean, Nolan's one of the few folks out there with the clout to insist that it should be SDR only, but I think we'll be pleasantly surprised when the movie hits UHD on or about the end of the year.

For whatever reasons, there seems to be no way to extricate one from the other so these discs are either SDR 709 or HDR 2020. And I'd MUCH rather have a tasteful HDR 2020 version of Dunkirk than an SDR 709 version.

Aren't all the HDR releases to date DCI P3? I didn't think anything was 2020 at this point, especially because there are no displays out there that can show it.

Yeah, 2020 is just the nominal container, inside there is DCI P3

they better stsrt utilising rec 2020 soon with the new samsung being able to do 110℅ of dci p3

Well, movies are finished for DCI specs, so it's not going to happen anytime soon...

It already did with Inside Out.

Yes, but 2020 is the container so it's just easier to refer offhand to UHD Blu in this manner. As mentioned above there have been some movies actually mastered in 2020, though animation is one of the easier sources with which to fully exploit that kind of insanely wide gamut.

You just said "it's not going to happen anytime soon..." but it happened in 2015.

[Kris Deering]

With only one scene, which had hardly any luminance, so reaching saturation wasn't an issue.

Just to go back to this, something to bear in mind is that BT.2020 is a non-constant luminance system for the home, so in SDR it isn't going to be the same representation as an SDR 709 version just with a wider gamut bolted on. It would need its own specific grading/mastering pipeline and I don't think many systems have bothered to provide such specificity during the UHD Blu process, which isn't all that surprising seeing as HDR and WCG for the home are so intertwined in terms of how/when they appeared in relation to the grading of home video versions. There was no need for an SDR WCG mastering system for home video before, and it seems to have been skipped over completely in favour of outright HDR WCG.

So you are basically saying that WCG (and higher color depth) is useless without HDR, something I have suspected for a year

[Geoff D]

I didn't say useless, I said there was no pipeline for such specific home video mastering....follow it through.....because the maximum grade that's been needed thus far for the home has been SDR 709. That is NOT to say that the actual uncompressed masters themselves are not WCG because they are (usually P3), but when doing the trim pass for video there was no physical need for a WCG version before UHD Blu came along.

So because WCG has appeared in the home video grading toolset at the exact same time as HDR the two have become inextricably linked at the mastering level, even though WCG SDR is indeed defined in the UHD Blu spec. I can tell you for an objectively-measured fact that the converted SDR 2020 signals from my player really do convey a broader range of colour than the straight SDR 709 conversion, but it seems as if the pathway to having something like this encoded straight to disc is all but non-existent right now.

I assume this will be the standard 'old school' Nolan 5.1 sound mixing and no immersive audio to speak of (cue the mass grumbling "ah, man it's not object based ....no sale") [roll eyes in head]

Not only that, but you'll be straining to understand what the actors are saying.

Nolan, as a sound mix supervisor, is atrociously bad.

I'm gonna give the movie about 10 minutes, but if I have the same experience I had when watching the IMAX preview, I'm just gonna get up and get a refund. I'll happily wait for UHD if it means I can actually understand the damn thing.

Dunkirk is getting a Dolby Cinema release!!!!!!

http://investor.dolby.com/releasedet...easeID=1030481

4K, Dolby Vision and Dolby Atmos. Here I come. I was already about to make a special trip to the largest IMAX Screen here in the Netherlands. But bye bye, this will be my first Dolby Cinema release.
