Hint: It is the attention to detail. For example in 1967 “Battle Beneath The Earth”, although TGM is more accurate, as the machine should be MARK 1 MOD 1.

Funny thing is the plot could almost be “ripped from today's headlines”.

Yes, because I thought it was relevant, not that I want to spam every thread with it.

Again, I am truly disappointed that the BDA didn't require a 12 bit spec with ICtCp rather than 10 bits and standard sampling protocols for these discs, so the studios didn't have to rely on an OPTIONAL Dolby Vision format to get us there. Dolby is correct in their assertion that with HDR grading, you really do need more than 10 bits per pixel to truly lessen the visual artifacts that can become exacerbated, such as banding. The key word "optional" in Hollywood means we're not going to use it.

I don't know if ICtCp is supported on UHD BD. I will try it on the DM4 add-on disc, when the time comes. Of course, need to also implement support in our tools first.

I do agree with the rest, I wish we would not have to use profile 7 for BD with the two layers. A single 12-bit layer would have been nicer. At the time UHD BD launched, I don't recall if 12-bit support was finished for HEVC. It is all a blur now.

With that said, I do like that the EL is based on the difference between the source and the decoded BL, not the pre-encoded BL. This means it could fix compression artifacts in the BL... At least in theory.

...as for HDR..., I hear the Dynamic Range is High... Just sayin'

DV improving compression artefacts, you say?

Along that line, we did the final build of the disc yesterday, so it is the 4/20 edition of the disc.

For OLED owners, knowing that DV when tone mapped on their display, tonal color differences will not be lost entirely. The way I see it, the brightness, saturation, and hue of each color can now be a more accurate representation of the peak nits and color volume of the consumer display.

I approve of that because Cuarón indeed is into HDR, and Dolby Atmos too.

This kind of messing about with the encoding of the base layer and enhancement layer is why DV compatibility in both player and TV is a must at this point for me. Doubt we've seen the last of these kinds of issues.

By my recollection the 12-bit pathway did have its advocates early on (e.g. Dolby, Disney, Fox, [Sony had its own 12-bit solution (https://forum.blu-ray.com/showthread...#post14627444] ) but, despite repeated ballots, 12 bit bit depth never achieved a majority vote, much less a super majority basically due to most voting members feeling/claiming that they would have had to wait too long for mass production of 12-bit decoders.

Yeah, but keep in mind, in the process, Geoff was comparing (some might argue ‘unfairly’) two award winning filmmakers (you know Cuarón, so for Steve check out HPA awards, nominations and years of experience) driven to perfection where they were given a lot of time and all the tools available with Lustre - https://forum.blu-ray.com/showthread...a#post15989953

v.

an automated process supplemented with Dolby v4.0 manual trim tweaking, which of course doesn’t leverage the ability/features of the whole color corrector, no matter the manufacturer.

If expense, access and time were not factors, who/what would you choose?

Yeah, but not every DV disc is afflicted in this way and StudioCanal proved with the Rambo discs that they can encode standalone HDR10 just as badly as they can the base layer of HDR10 + DV, it's just dumb ****ing luck that the DV EL is there to save the day on several of their UHD discs. The example I gave of Universal's First Man was a slight niggle in an otherwise lovely HDR10 base layer encode, whereas if SC had handled that exact same master - with all that 16mm and 35mm grain - then the HDR10 would've been tragibad.

Paramount's earlier DV discs had some shocking compression on the HDR10 layer which too was cleaned up quite nicely in DV - I find the HDR10 layer of SPR to be literally unwatchable, and I've spoken to a pro compressionist who found it equally appalling - but they seemed to get the problem under control and the HDR10 layers of their DV encodes have been fine ever since. There was/is a definite issue with some encoders and this whole BL + EL rodeo but the majors have gotten on top of it. It's StudioCanal who haven't gotten the memo yet, though they may have turned out just as badly in HDR10 only, unwilling as I am to give them the benefit of the doubt

Very puzzled by this comment as I'm not the one who didn't like how their SDR converted DV looked. I used it as an example of how that specific part of the process frustrated said director and/or colourist, so if the extra trim passes help - as how Stacey said it would help SDR in particular, hence me mentioning it - then that's for the talent to decide.

Youse guys are the ones who are bigging up these features, now you're throwing them under the bus? I don't see how I'm "unfairly comparing" anything as I've already said in this very thread that DV trim passes - no matter hpw many bells and whistles - are gilding the already extensively-graded lily: https://forum.blu-ray.com/showthread...9#post15981559, now you think I'm saying they're more important than that? Wut?

sorry, no offense intended, as I’ve been speed reading everyone’s posts lately while at the same time working hard this holiday…and battling a cold to boot. totally my fault if I misunderstand something you said

what’s worse, due to said work i hadn’t known of palace v. ars result which may tempt me grab one of these mugs and have it filled with something mind numbing out of embarrassment….



be kind and tell me at least if the prem title is still in play …..did liverpool win this weekend or drop points to city?
