Same reaction. And note how pathetic and ludicrous is it, in the year 2020, that the disc you get in the post is a DVD. Not even a blu-ray (they have recently started with some blu-rays, but only for a small number of titles). No 4K blu-rays, as that would expose how inferior their non-HDR hardware is.

edit: That was a bit angry and ranty, wasn't it. I'm thrilled with the free berlin philharmoniker concerts though! Great stuff

Gents

Please refrain from derailing this thread (or any thread) with endless unrelated posts about COVID-19. This is the HDR discussion thread, not a chat room to be monopolized by a few individuals for whatever they feel like posting.

These are trying times for everyone, myself included. The mods are getting a lot of complaints from members who don't want to wade through so much unrelated stuff on this and other threads.

Thanks for understanding....and washing your hands

mrtickleuk and DanBa, you guys are reciprocal givers, but a shout out to the complainers of the unique situation - I think it’s only fair you guys actually contribute something HDR-related to this thread more than once in a blue moon, rather than simply regularly reading it and seldom, if ever?, offering anything of substance in return. On the contrary, gents, perhaps follow this -

I prefer not to judge, but no matter life’s endeavor, only taking, day after day, and then selectively complaining seems rather selfish, if not hypocritical to me.

Penton-Man you alone contribute more to this thread than anyone else but maybe people come here for an escape. I believe the media is overblowing everything.

I can appreciate that. So, with that in mind, to navigate the immediate situation, see….https://www.smpte.org/smpte-webcasts
Then, ergo, now free to all ->
https://www.smpte.org/webcast/hdr-4k-and-beyond
(albeit a bit dated ^ and fundamental to daily readership here, but for those unfamiliar, it does covers such things as the differences between the 2.9 and 4.00 toolsets at around the 1:13:24 timestamp).

And who knows, SMPTE may have a fresh HDR-related webcast in the future. As far as any news on the HDR iteration of Top Gun: Maverick I can offer nothing, however there is a new interview in Empire Magazine with Jerry and Tom - https://www.empireonline.com/movies/top-gun-maverick/

No, because…..there’s a YouTube going around on how the unique situation has affected Tom and Jerry and I wouldn’t want to give any sour crispy lemon the weakest excuse to get this thread locked, or me suspended….not to mention, as I notice above giving Waboman even more reason to day drink at breakfast.

I should really know more working as a photographer(although selling prints is my business) but is there actually a different in DR between the raw data of filming in the past on digit(say at HD) and the released footage? basically is there potential for improvement of such films via HDR/WCG releases even if there isn't in resolution?

On the photography side that's certainly the case as your dumping DR and colour data converting from RAW to Jpeg and indeed even moreso when making prints with limited DR, a great deal of my editing work tends to be about compressing the DR within the range of the print.

Yes. My thoughts on some UHDs of movies shot on the 1080p Genesis (a rather lovely example of early digital cameras) make it quite clear that there's so much more range there than people think:

Zombieland 4K UHD (2009) (10th Anniversary Edition)

Predator Trilogy (1987-2010) 4K UHD Predators (2010)

That was great, thanks so much! I did recognise the graphic at 1:18:00 !!!

I'm getting the impression that a great many of the improvements Dolby Vision offers, are for the toolset to make a nicer SDR grade automatically, or a nicer low-nit (600 nits) grade with some manual trims.

That's all well and good but I always struggle to explain why Dolby Vision is better than, say, HDR10+, when on two otherwise equal 1000nit displays. I can tell people that iCtCp is better, but their eyes glaze over. I can try to explain that 12bit is better than 10bit, but of course I'm being disingenuous: 12bit Dolby Vision is just no longer available via any streaming service in the world, and probably never will be now that Profile 4 +FEL is all but banned.

The only chance of consumers ever seeing 12bit Dolby Vision now and in the future is from discs, with their shrinking market share (which I lament greatly) and Dolby themselves trying to stop people using a FEL full enhancement layer even on Profile 7 ["The MEL can be used to minimize the processing requirements for the enhancement layer and thus ensure broader use among UltraHD Blu-ray SoCs." - Dolby's http://www.dolby.com/WorkArea/login.aspx?fromLnkPg=1 document, old version, that wording has been removed!]

So the future looks very bleak - instead of 12 bit Dolby Vision it's going to be just 10bit, after all the super-impressive technical wizardry to make 12 bit possible (2 streams because the HEVC hardware decoders are for 10bit) I know that Vincent Teoh has done a small number of side-by-side comparisons but my family really struggle to see subtle differences. It seems like a losing battle. If I'm missing a pithy simple explanation of why Dolby Vision is better on an existing high-nit HDR display now other than "ermmm, well it's just better innit!"), that I could repeat back, I'd love to hear it!
