HDR Discussion Thread

[PaulGo]

I have watched the same movie in 4K HDR and in 3D. I find that 3D (if done correctly) can do more to immerse you in the movie than 4K HDR. I wish 3D were part of the 4K HDR standard. Perhaps after the Avatar sequel.

Now (as of yesterday) available for download, V4.0 firmware for the Sony FS5 which offers four selectable settings for hybrid log gamma HDR recording/playback/output, namely HLG, HLG1, HLG2 and HLG3.

Eyeball 101 or Shining the Light on dem Eyes



Pupils don’t ‘contract’. What contracts (or expands) is the muscle, namely the sphincter papillae. Pupils are essentially openings which constrict or dilate, as I think human hobbyists can intuitively figure out, be it smaller or larger, when exposed to light……unless of course the person unfortunately has a Marcus Gunn pupil (perhaps a topic for another day).

Consider that ^ to be rather basic knowledge. The post above that regarding shooting the Blue Crew vs Giants next week to be more insider-ish info.

The Next hottest thing in HDR this Halloween?

Should look pretty spectacular on Netflix. HUGE fan of the retro themes here.

Is season 2 confirmed to be in HDR? That would be great. Really good show.

Netflix has a a schedule of listing and it's listed as hdr. Also, I believe the company who did the hdr graded tweeted about it a little while back, I believe.

…Take color, for instance. With our Oppo 203 and LG OLED55C7 combination, the Dolby Vision Despicable Me movies display an unprecedented array of tones and tonal subtleties. Everything from the animated skin tones to background walls and locations contains subtle variations and accuracies of color you just don’t get in HDR10 – a comparison verified by playing the discs’ HDR10 ‘core’ video through the Panasonic UB900 Ultra HD Blu-ray player onto the OLED55C7.

This helps pictures instantly look more detailed and refined, despite the fact that Dolby Vision isn’t capable of actually adding more pixels to the 4K source pictures.

The Dolby Vision transfer doesn’t just portray more subtle colors than the HDR10 transfer either. Some colors also look slightly different in hue and tone; and invariably our impression was that the DV versions were the definitive, accurate ones.

Startling in its brilliance, too, is Dolby Vision’s mastery of light. Somehow the technology seems to deliver purer, brighter highlights than we've ever seen from the LG OLED before, while simultaneously delivering dark scenes with more richness and subtle light detailing.

Actually there seems to be more definition between subtle light differences in every part of the Dolby Vision image, giving it a more stable, rich, deep, solid appearance that looks almost three-dimensional versus the flatter, less precise HDR10 picture.

It’s worth remembering at this point that AV brands not signed up with Dolby for Dolby Vision – including Samsung and Panasonic – tend to suggest they can deliver equivalent results to DV by just applying their own processing power to HDR10. Having played the Despicable Me discs in HDR10 into a reference Samsung UE65KS9500, though, while that set delivered brighter light peaks than the Dolby Vision picture on the LG OLED, it couldn’t match Dolby Vision for light and color subtleties….

Again, I think this indicates that dynamic metadata can have a positive influence on a high nit display. The only quibble I have is with the title. I don’t believe there is any real evidence that we consumers have to pay a premium for Dolby Vision at any point of the chain. Perhaps for the current DV players, maybe?

CIC25 Workshop 2
In order to address these issues, this workshop brings together researchers from academia and key companies in the cinema and TV sector, to present their latest research outcomes and discuss their outlook on the topic. The goal is to provide an opportunity to encourage a closer collaboration among the image processing and vision research communities. The following is a list of speakers with titles and abstracts of their talks:

Dude, my forums radar doesn't go off just because someone spells 'colour' correctly.

Heh. Yes it's in the same country as me, but too far for my casual interest I'm afraid!

I see the direct link ^ didn’t go thru using the Blu-ray.com platform so that ^ comment may seem ambiguous for those who aren’t Society members. For clarity, from the upper left of the home page – http://www.imaging.org/site/AsiCommo...ion/Login.aspx, go to Conferences -> Industry and Standards Events -> CIC25 -> Workshops.

Also presenting is Jan from Arri providing proposal(s) as for closing the gap between research in entertainment media and missing psychometric data for the human visual system.

Don’t you mean provincially?

On the other thread I see you liked Yedlin’s stuff - https://theasc.com/articles/a-clear-...-of-resolution . After the appreciation of using a 4K or higher rez camera for supersampling and the rather fundamental decision to choosing the camera and resolution of the master for their motion picture, these days in the emerging era of HDR, in order to harvest/work with/deliver optimal picture detail in terms of color fidelity and dynamic range, aspiring astute cinematographers should (and some with a technical background are) actually be more concerned with bandwidth constraints within the DI theater that they choose because that can have a greater effect on the production and picture quality of the finished product than the resolution manifesto that Steve Y. presented.

Having a 16bit file in an ACES workflow as a digital intermediate source throughout the post is important for an optimal and efficient process to picture quality outcome.Despite the wide dynamic range of the cameras that Steve evaluated, in some post facilities the DP doesn’t get all of that range because it’s been truncated to the more bandwidth friendly 10bit DPX type file.

Multi-term past President of the ASC realizes this and spreads the word

I see that now from your location (Birmingham). That would be a big commitment by you or anyone else for that matter when eventually the newest shootout will probably be covered later in articles on the net anyway.

[Geoff D]

I'm fully aware of 10-bit still being a thing in post: https://forum.blu-ray.com/showthread...9#post13617049

But when it comes to what Yedlin was trying to say about the pixel race then I can respect that for what it is, given how some people really do just focus on sheer numbers alone rather than what the end result looks like. We see the same shit day in, day out on this forum relating to 2K upscaled UHD.

Well, seeing as how your countrymen react when someone wins/loses a soccer ball (sorry, football) match you can't be too careful.
