The ~ 3 ½ min. timestamp of thee above ^ Panavision clip reminds me.

In the Holiday and family spirit I’ll offer a real world public service tip regarding astigmatism and human vision. For those with significant astigmatism and approaching the need for this surgery - https://forum.blu-ray.com/showthread...t#post14266554 , despite the cost (easily $2,000 or more for the lens itself) and the fact that generally insurance companies don’t cover it, so it’s all out of your pocket with no reimbursement, still, some people should consider choosing a premium lens like a toric IOL (ex. AcrySof IQ) over an insurance-covered basic lens.

If readers here are not yet confronted with this visual issue, feel free to confidently pass on the above info to your parents or grandparents, as the case may be and if they are indeed candidates (the ophthalmologist will do one or more IOL masters first to indicate the functional value) for a toric lens and if they can’t afford such a premium, advanced lens…I think it would make a thoughtful Holiday gift.

In December, when Amazon will also be releasing HDR10+ content.

No matter the format, I can’t believe my wife is dragging me to watch this motion picture with her for the umpteenth time - https://www.amctheatres.com/titanic?sf174074862=1

Oh well.

"SAN JOSE, California – November 28, 2017 - HDMI Forum, Inc. today announced the release of Version 2.1 of the HDMI® Specification which is now available to all HDMI 2.0 adopters. This latest HDMI Specification supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps.
Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable. The cable ensures high bandwidth dependent features are delivered including uncompressed 8K video with HDR. It features exceptionally low EMI (electro-magnetic interference) which reduces interference with nearby wireless devices. The cable is backwards compatible and can be used with the existing installed base of HDMI devices."
https://www.hdmi.org/download/hdmi_2...Release_EN.pdf




"All products must comply with Version 2.1 of the HDMI Specification and the HDMI 2.1 Compliance Test Specification (CTS); and until the CTS is available and a product has passed compliance testing a product cannot claim to be 2.1 compliant or market that it supports 2.1 features.
The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018."

HDR10+, or any dynamic HDR, is possible with HDMI 2.0b, as has already been confirmed multiple times.

recorded narrative high frame rate project, for example – https://forum.blu-ray.com/showthread...e#post13425318

latest being end-to-end demonstrations of high frame rate production for broadcast sports - https://forum.blu-ray.com/showthread...e#post13461582 <– something not mentioned in the press coverage for the ice hockey project was that based on the French experience with that project, the French producers believe there are now no real technical hurdles in the production chain yet to be solved, except for professional monitoring and recording, so, given that, HFR should be the next big milestone in next gen video (in terms of added value to picture quality).

Like with PQ for HDR in Sept. 2014 – https://forum.blu-ray.com/showthread...ar#post9754213

You heard it here first.

But if you read the document it's obvious the products will not be ready until later next year, or even 2019:

"The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018, and HDMI adopters will be notified when it is available."

[LordoftheRings]

Yes, Q1-Q3 2018. But today is the day it was revealed the official way, in preparation for a better future.
This causes for celebrations for the 2017 remaining year, and during all 2018 long, and beyond.

Methinks.

And, hopefully the next HDMI 2.2, perhaps in 2020, will bring back 3D, but this time around with 4K HDR resolution, and with Dolby Atmos sound. Faith is what makes our world the way it will look tomorrow, today.

Marantz can certify the available Marantz SR7012 for HDMI 2.1 eARC when the HDMI 2.1 CTS spec is finalized.
"eARC (Enhanced Audio Return Channel) supports the transmission of 3D audio from your TV apps with a single HDMI connection for the simplest setup. This feature will be enabled via a future firmware update."
http://us.marantz.com/us/Products/Pa...oductId=SR7012

According to Jeff Park, Director of Technology at HDMI LA, a HDMI 2.0 => HDMI 2.1 firmware upgrade is possible if the HDMI chipset was designed to be upgradable.

I often have difficulty in telling when you are serious, or “humorous with subtlety”…. https://forum.blu-ray.com/showthread...y#post13635086

Good to see the clear positivity in your follow-up post though, for I wasn’t sure.

Where at next year’s 2018 Entertainment Technology in the Connected Age Conference should have good speaker representation by Dolby labs and use said screen to illustrate the value of HDR.

The way that I think about Dolby Vision is like a funnel. The HDR grade is the wide end of the funnel – high dynamic range (HDR), large color gamut, and possibly high resolution and frame rate.

The Dolby Vision process analyzes the HDR grade (in the grading software) and the Dolby Content Mapping Unit (CMU) takes the metadata produced by the analysis process (embedded over SDI) and in real-time creates a Standard Dynamic Range (SDR) version of the project (the smaller end of the funnel).

Unlike HDR10 (another HDR standard) where mapping from HDR to SDR is passive and applied over the entirety of the program, Dolby Vision allows for frame by frame or shot by shot SDR mapping. Meaning that the colorist, DP and director can provide creative input to how the SDR version of the project is derived by use of ‘trim’ controls within the grading software while targeting a chosen SDR display spec (usually 100-nit gamma 2.4).

Trims can happen on a frame by frame or shot by shot basis so that that the SDR version of the project matches as closely as possible to the original intent of the HDR grade.

I know this is going to sound funny, but by starting with the HDR grade and deriving an SDR grade from that through the Dolby Vision process, I feel like I’m getting better SDR grades than I would have if I did the SDR version alone.

What’s more? Instead of having to do two separate grades, the trim process on most projects usually only adds a few hours of time, which is way more efficient than two separate grades.
