That's interesting though about the grey bar problem, thanks for posting that. I mean if they were doing that wrong there are probably a plethora of things they're still doing wrong with Dolby Vision. |

I already said why: if something is mastered with a good chunk of brightness then the hit that DV takes just isn't going to be as readily apparent...but it's still there compared to the HDR10 output. I've verified this on several DV joints.

So do you really think it's just Sony's implementation of DV or it's probably happening with LG OLEDs too and they just don't get bright enough to really tell the difference anyway? What do you do with a disc like Saving Private Ryan where the chroma compression is a lot better in DV? Just deal with the decreased brightness?

Oh man, oh man. Glad you mentioned that as it slayed me once again last night. Every time that happens I feel like crying, yet he's only been on-screen for like 10 minutes! It's such a gut punch and the performance is astonishing: the twitching on his face, the desperate realisation in his eyes that these are his last moments, and then the collapse like a puppet with the strings cut. Wow.

I was on AVS the other day reading some old stuff by a pro-calibrator about my television and he talked about how accurate and easy to calibrate it was in SDR with local-dimming on normal. Then he talked about how out of his mind calibrating it in HDR with high local-dimming was making him. HDR is fun stuff!

So even though Dolby Vision is actually supposed to help get the best out of TVs with lesser capabilities, in fact its unusable on many, imo. Now I don't know if that's Dolby Vision's fault or LG's fault, but in the end, it's bad news for me and I'm sure many others. As far as HDR settings, I've given up on trying to use HDR test patterns. I just go by eye at this point. I have a good idea of when blacks are starting to crush or things are blowing out. Trying out the Mehanik HDR10 test patterns, they specifically advice not using the brightness slider in the TV's menu with the patterns (they say it's likely broken for HDR regardless of which TV you have, and I'm not going into my service menu as I don't have the experience or knowledge or equipment). So it seems to me most people are probably just winging it with HDR settings. I don't think anybody really knows quite where their settings should be for HDR, and honestly, I think HDR is kinda all over the place anyways from one disc and studio to another. I definitely find that I have to make minor adjustments (a few clicks) one way or the other for some discs. It seems so far with older films that have been remastered in 4k/HDR I can leave my brightness setting around 49, but for newer films shot digitally, I get black crush at 49 and need to bump it up to 51. If I have my set at 51 for older films the blacks are too bright and washed out. 2001 has very light blacks for me - I need to drop it way down or space looks awfully grey.

The HDR debacle is one reason why I've held off on getting a UHDTV. I'm hopeful that the new industry standard HDR format - for both theatrical and home presentations - being hammered out will make things better, but that's still a long way off.

As for this other HDR format, I'll file that away with other predictions such as "replicated 128GB discs are coming" and "Peter Jackson will redo the CG in all the LOTR movies when the Avatars are finished". ![]() |

I think he was just saying the bright bursts of high nit content were screwing with his gamma calibrations, so I don't think it was my set in particular. Just him getting used to HDR calibrating I guess? I dunno.

I still hold that despite the magic 12 bit processing of DV, most people would be better off if studios just put all their effort into making the best HDR10 encodes they possibly can *cough*StudioCanal*cough*. Outside the possibility of true 12 bit panels reaching consumers sooner rather than later, I only see it creating more problems than it's worth.
This is coming from someone who's never mastered a single piece of content in their life though, so what the heck do I know? |

But gamma control isn't used with HDR, or at least it wouldn't normally be. Depends on the telly I guess. That goes to the problem of how does one regulate the Perceptual Quantiser EOTF curve that has replaced Gamma (with a capital 'G', as in the SDR EOTF), when you've only got Gamma-centric controls to control it with. Thankfully most TVs tend to hug the PQ curve pretty well out of the box (tone mapping irregularities aside) but even so, I'd have thought that finer controls over specific HDR picture functions would've come along by now. Seems like most manufacturers are still gearing their TV processing for SDR first and foremost and then shoehorning HDR functions into that by way of gamma conversion.

Check this out:
STM's first home video release way back in October 1980(nearly 2 years after it's 78' theatrical release!)...reviewed in The Videophile: Scroll down to page 35-36: http://magazines.lddb.com/The.Videop...ber%201980.pdf The reviewer gave the picture quality a thumbs up: "Although I would rate the tape's picture quality tops...…" ![]() ![]() ![]() |
