Salty,

Thanks for the reply; being a novice at the whole 4K/UHD thing, I'm still somewhat confused; are you saying the Dolby Vision-encoded disc, whatever the title, will be kind of "downconverted" by my TV so it plays in the form of HDR my set offers? And being that I haven't actually seen any HDR10 material, I don't know how "good" it's going to look; is an HDR10 presentation vivid and detailed enough for an enjoyable viewing?

But football players needn’t worry too much about lower extremity injuries (shown at the beginning of the commercial) impairing their quality of life later on in age because worst case scenario, joint replacement has evolved significantly since then. What they have to be much more concerned about is CTE -

And the many years the NFL purposely ignored or buried the issue.

Seems you soccer hooligans are drinking Moscow dry. You'll need to round up some of your heavy hitters and send Mother Russia more wodka. https://abcnews.go.com/International...ry?id=56025224

You're a Sony guy, right? I can't recall. But I think you are. Anyway, remember the Qualia line? The Q006.

But I digress, comrade, another round.

I'm not Salty but the HDR10 is on every UHD disc, no conversion will be needed. As far as I know there is so far little to gain by having Dolby Vision compared to plain HDR10, but it can of course change with TVs getting better every year. Check out

Thanks very much, Leter.

Ultra HD Blu-ray (4K) Discs and High Dynamic Range (HDR) for Dummies

I don't think that any two users have the exact same experience. Do read the linked reviews of Geoff D in the thread ^. I don't have 4k yet, but I am very much looking forward to getting it. Just waiting for all these knowledgeable "Beta" testers finish their work.

IntelliVolume,
Here's a thread that's more useful to the 4K folk here (less incendiary than that real or fake 4k) that's self explained by it's name.
The OP is maintained by HD Goofnut.


List of UHDs that utilize 4K or Higher Masters note there is more than one entry if different versions exist outside US

There's another thread for UHD discs containing Dolby Vision, by zmarty.

It’s just a list that people find helpful, since you can’t search the database for that factor. I understood your smilie.

What with all the gnashing of teeth over the 2k - 4k discussion, it benefits some folks.

I notice a lot of rambunctious supporters there ^ for Poland draining the drinkin supply.
Believe me, those Poles party hearty and work hard, e.g. doing HDR tests with new RED cameras very recently –





Wabo, allow me to try to get you at least a wee bit interested in the tournament. You like seeing, not only a team desperately fighting for its sustained existence, but also millions of people in a powerhouse soccer country hanging onto a cliff by their fingernails and experience what happens?

Yup, even retrospectively posting Qualia 006 and 005 summary executive meeting notes, word for word - https://forum.blu-ray.com/showthread...ia#post9740242

The idea of the display technology may seem rather matter-of-fact these days, but I’ll remind folks that the 005 was the first commercially available consumer display to use LED backlighting, the significance of which few hobbyists appreciated back then.

^ Long video clip as I recall discussed several months and then just several weeks ago in this thread. For novices (like newly arrived and welcomed IntelliVolume) to the topic of how calibrators feel different HDR formats compare and who, while watching, might otherwise get bogged down in the details and length of that video, to cut to the bottom line -

Also note that Vincent stresses he (at the time) hadn't been able to do a comparison between HDR10 and dolby vision with high-nit-capable displays. (The thinking being that low-nit displays will always benefit more from the flexible tonemapping afforded by dynamic metadata than high-nit displays.)

Six months later, in April of this year, he was finally able to do the first such comparison:

Low nit displays will always benefit more from better tone mapping (dynamic or otherwise) IMO, but that's not to say that high-nit displays can't have their own benefits from it. I haven't been bowled over by Dolby Vision on my ZD9 thus far in terms of how it's using the actual range vs my TV's own tone mapping, but it's brought subtle gains in other respects which I've definitely appreciated.

What I didn't expect was how it tidies up some of the very worst compression I've seen on a disc from a major studio (BD or UHD) in years, namely Saving Private Ryan which is disgracefully bad on the HDR10 layer, a view backed up by a professional compressionist whom I won't name. But the DV output genuinely improves the horrendous blocking, it's still there but nowhere near as bad.

But you have insane nits plus world class tone mapping.
If a display didn't need any help it's the zd9

[Geoff D]

Which is pretty much what I said, but DV has deffo brought improvements in other areas.

As to refined image quality, unfortunately, apparently Gen Z doesn’t view it as much of a priority as you old timers do:
“Considering the range of viewing platforms teenagers gravitate toward, do you think high dynamic range (HDR) will play into viewing habits for teenagers, or is it not even on their radar?”…….https://www.creativecow.net/intersti..._habits/1&id=0

Note to Waboman: at least Helen has her #1 priority in order

I hope that hyperlinked post in paragraph 1 ^ with regards to specifically describing one real world value of how HDR is superior (mitigating blown out highlights) to SDR didn’t upset my friend Steed, as I didn’t realize until today while googling opening matches for next season’s Premier League that SunderlandFC was relegated, yet again (to League One).

Sorry my friend , man, you folks must be really suffering up there in N.E.

On the topic of ^ workflows, ICYMI, for those curious to know more about/or just learn the terminology (rendering, etc.) related to basic overall workflow regarding episodic TV and features from acquisition to localization and delivery to the consumer, starting with a presentation by the DIT Simon Jori (whose credits include The Revenant), this is a good overview…..
