4K Movies Releases

[Geoff D]

I'm not dropping a couple of hundred quid on a streaming thingie. I spent £20 on a reconditioned chromecast for a TV in another room and have barely touched it, when the ATV hits that price point then I'll bite so that I can have another useless bit of kit hanging from the side of my TV.

It's about as good as you can get for streaming, IMO.

My Roku can pass Atmos.


And they didn't locate their HQ in Ireland to avoid taxes and have slave labor build it.

Hostiles, a new western starring Christian Bale, shot on 35mm anamorphic and has a 4k DCP.

I, myself, don't use that as a measurement for quality. Film having more K than digital for the last 20 years was simply a factual statement.

Since The Darkest Hour doesn't seem to be getting a UBD release, but will likely get released somewhere on digital UHD, I thought I'd share this article here. A great interview with colorist Peter Doyle: http://postperspective.com/peter-doy...-darkest-hour/

Here as an excerpt focusing on HDR:

Darkest Hour and HDR
On Darkest Hour, Doyle built the DCI grade for the Xenon projector, 14 foot-lambert, as the master color corrected deliverable. “Then we took what was pretty much the LAD gray-card value of that DCI grade. So a very classic 18% gray that was translated across to the 48-, the 108-, the 1,000- and the 4,000-nit grade. We essentially parked the LAD gray (18% gray) at what we just felt was an appropriate brightness. There is not necessarily a lot of color science to that, other than saying, ‘this feels about right.’ That’s (also) very dependent on the ambient light levels.”

The DCI projector, notes Doyle, doesn’t really have “completely solid blacks; they’re just a little gray.” Doyle wished that the Xenon could’ve been brighter, but that is what the theatrical distribution chain is at the moment, he says.

When they did the HDR (High Dynamic Range) version, which Doyle has calls as a “new language” of color correction, they took the opportunity to add extra contrast and dial down the blacks to true black. “I was able to get some more detail in the lower shadows, but then have absolutely solid blacks — likewise on the top end. We opened up the highlights to be even more visceral in their brightness. Joe Wright says he fell in love with the Dolby Vision.”

If you’re sitting in a Dolby Vision Cinema, says Doyle, you’re sitting in a black box. “Therefore, you don’t necessarily need to have the image as bright as a Rec 709 grade or LAD gray, which is typically for a lounge room where there are some lights on. There is a definite ratio between the presumed ambient light level of a room and where they park that LAD,” explains Doyle.

Knowing where they want the overall brightness of the film to be, they translate the tone curve to maintain exactly what they did in the DCI grade. Then perceptually it appears the same in the various mediums. Next they custom enhance each grade for the different display formats. “I don’t really necessarily call it a trim pass; it’s really adding a flare pass,” elaborates Doyle. “A DCI projector has quite a lot of flare, which means it’s quite organic and reactive to the image. If you project something on a laser, it doesn’t necessarily have anywhere near that amount of flair, and that can be a bit of a shock. Suddenly, your highlights are looking incredibly harsh. We went through and really just made sure that the smoothness of the image was maintained and emulated on the other various mediums.”

Doyle also notes that Darkest Hour benefited from the results of his efforts working with Technicolor color scientists Josh Pines and Chris Kutchka, working on new color modeling tools and being able “to build 3D LUTs that you can edit and that are cleaner. That can work in a little more containable way.”

[Geoff D]

That rationale for bringing down the blacks in HDR would explain why he chose to thicken up some of the Harry Potter HDR grades in the black levels vs the existing SDR version. But what it doesn't explain is that the Potters which already had dark dense blacks in SDR were thusly lightened up quite noticeably for the HDR grade, all of which were done by Doyle.

It's funny that most HDR grades - I'm speaking generally now - don't tend to reflect the historical SDR version in terms of preserving that tone curve, not the EOTF itself but just the intended way that the lights and darks should fall in any given shot. As with the Potters you tend to get the opposite in HDR when it comes to pre-existing SDR versions: if the SDR is awash with colour then it tends to get toned down on the HDR, if the SDR has thin grey black levels then the HDR tends to darken them down considerably and vice versa, VERY much vice versa in the case of the Nolanses for example.

For a moment there ^ I thought I was in the HDR Discussion thread rather than the 4K Movie Releases thread, oh well,
memories and traditions

For those not in the know, Josh does get out the house and over to the desert once in awhile - https://forum.blu-ray.com/showthread...h#post10417134

Throw this into the "bummer" bin.

Well, if nothing else my bank account is grateful.

So, that means no catalog Disney titles will be forthcoming on the UHD Blu-ray format for the time being. Not exactly good news.

Especially with all the catalog marvel movies.

What's more confusing is that the reports the past 2 years was that Disney was preparing many movies for release on the format such as Dr. Strange,, civil war, etc.

I could care less about Marvel films as I find them mostly cookie-cutter fare, but there are a TON of great classics swept up in this unwillingness to release catalog titles on UHD Blu-ray. And soon you can add Fox titles to that list.

You could care less or couldn't care less?

Given the quality of these modern superhero films I probably could care even less.

[d514]

Even if Disney is already planning to release catalog titles on 4K in April and they are planning to announce it in March they would be saying that there are no plans if you ask them in February.

[ghornett]

Huge bummer, hopefully they go back on that.

[Lion]

Given it wasn't long ago Disney hadn't even got on the UHD bandwagon I'm just happy with new releases for the time being..

[Geoff D]

Yeah I guess, but them not doing catalogue titles speaks volumes as to how they regard the state of play. If Fox were bad for catalogue releases then Disney are even worse, and they'll both be under the same roof in a year or two. Oh joy

ray, who specifically reported that?

I think we know, Mr P. The name rhymes with Hill Bunt.
