Looking like a professional HDR/WCG workflows proposal from ML may not get uploaded in time.

I have an LG 43UH6500 and have watched a few 4K-UHD Blu-Ray discs on it via my XBOX ONE S. I've noticed that while HDR does make a huge difference, as it features more vibrant colors and more contrast between various shades of colors, it looks oversaturated at times. This can be observed in Batman v Superman, particularly in the red and orange of explosions, Superman's heat vision, and Doomsday's heat vision; it can also be seen in X-Men: Apocalypse, particularly in the red of Cyclop's optic blast. Is this normal or is it due to an issue with my TV or XBOX ONE S? Is it possibly due to the fact that all of these visual phenomena are CGI effects? Overall, HDR looks much better than SDR and is something that I enjoy, but I find this characteristic to be odd.

Do you have LG's Deep Color setting on? The Xbox has been shown to have troublesome disc playback apps as well.

It may also be a matter of calibration. We still have yet to see professional UHD Blu-ray calibration discs made available that can compensate for the various flavors of HDR as well as P3 and Rec 2020 color gamuts, etc.

I don't know how much good UHD calibration discs will be when most of the HDR displays on the market right now don't allow any calibration past a 2-point grayscale adjustment.

Both sides of the equation have to equal up, that's for sure.

wrt ICtCp, a proposal document suggesting draft text for ICtCp support in HEVC with traditional full range color mapping was submitted to the JPEG/MPEG/JCT-VC/VCEG/JVET Meetings starting today.

As to the displayed HDR/HFR images on the right….https://forum.blu-ray.com/showthread...r#post12672382

they were from a tennis tournament in France.

Reminder about what’s planned to come with HDR versioning and Billy Lynn’s Long Halftime Walk(BLLHW) -> proceed to underlined hyperlinked article in this post.

Ah, I didn't realise that they're actually changing around the resolution and frame rate of the source itself! Something that's intrigued me since El Rey Del Mundo mentioned doing variable fps on the Avatar sequels is just how that can be achieved. This being (presumably) an interop DCP is it capable of actually changing fps mid-flow, or is it at a fixed fps of 120 with some sort of black frame insertion or other such frame doubling/interpolation for the 60fps scenes? THIS NERD MUST KNOW!!!

Yes, I have LG's setting, Deep Color, enabled. However, the issue has gone away, though I don't know exactly why. Perhaps it was resolved by the automatic update of the XBOX ONE S' Blu-Ray app. Either way, HDR looks amazing.

It is not capable because DCPs don't support variable rates and even if they did, most of the 3D projector systems need a painfully noticeable amount of time to adjust their sync when the projection rate changes. If you want the appearance of 60fps in your 120 DCP, it’s easiest to repeat every frame twice (the later solution you mentioned in your post).

Okay then .....I've got a few moments to add on.

“To those who may be hesitant to watch a film with such clarity, Lee reassured, “It's very clear to me that our eyes like details. When the information is sufficient, it's pleasing and relaxing. … When it's not efficient you stare harder and it's frustrating.”, excerpt from
http://www.hollywoodreporter.com/new...source=twitter

It’s also clear to pilots and aviators for if you ask them they’ll tell you that they easily prefer viewing 120fps imagery over that of 60fps when training on flight simulators –

It’s also clear to those possessing this (a critical part utilized for optimal functioning of the most complex machine there is on earth)…



rather than this….

This critic gets it - "record this moment", but warning, so as to avoid ruining the plot of the movie before you get a chance to see it, perhaps best to just read the first and last paragraphs of the review….

Not to forget with regards to thee HDR watershed moment, the first theatrically released feature motion picture in HDR was Tomorrowland .

Honorable mention going to the short film “Emma” which was conceived as an HDR project from the get-go and deserved the appendix footnote it received in the October 2015 SMPTE SG HDR Report.

Dolby vision news. Still no Disney mentioned. Also looks like 6 studios have plans to offer discs with dolby vision. Everybody except fox and Disney.

Completing the above ^ retrospective post….

I figure that some dedicated movie watchers have already seen Tomorrowland at a commercial theater and or if local, having taken advantage of the unique opportunity, at Dolby’s private theater on Hollywood Blvd., as prompted.

So, I’ll forego running the T-land trailer and even if only in SDR ( hey, the on set monitor that the DP used during filming was only SDR) proceed with linking Emma’s trailer to give folks as idea with regards to production design and lighting as to what the filmmakers had in mind (as I mentioned on Blu-ray.com a good year before the SMPTE SG HDR Report was published, the writer for Emma was Rod Bogart of the OpenEXR high dynamic range image file format development and implementation fame) had in mind in order to create a compelling short film that could purposely leverage HDR….

Not forgetting this ^ was a short independent film with a humble budget. I’m informed that the entire short film can be viewed for free on Amazon Prime….https://www.amazon.com/dp/B01LPG4PRQ
