So anyway, why all the gibberish on the last page about 10-bit? Well, to properly bring consumers WCG (Wide Color Gamut - be it DCI P3 or Richard’s fave - B.T. 2020), we need 10-bit video.

…..”We shall then enjoy a specially invited paper describing work carried out by a collection of international laboratories. They will present, for the first time, subjective performance results of HEVC” - http://www.ibc.org/page.cfm/action=S...D=30/listID=74

As an aside, and not mentioned in the above ^ intro, one of the listed labs is currently discussing which HEVC encoder to use for a potential new project to encode HDR content.

Wow….eye-opener, investigating hotel room rates at quality hotels in Amsterdam right now as compared to during IBC week . The phrase ‘price gouging’ comes to mind.

Perhaps a nice B&B (Bed and Breakfast) as an alternative?
Hmm…

Something to keep in mind for some perspective regarding WCG (wide color gamut) be it P3 or BT.2020 and next gen video. Do not expect a ‘wow’ knock-your-socks-off experience with all content encoded and displayed in a color gamut wider than Rec.709.

In other words, despite what those pretty colored CIE 1976 u′v′ chromaticity diagrams indicate that people enjoy posting on the internet to show how much bigger P3 is to Rec.709 or BT.2020 is to P3, fact of the matter is with *real life imagery/material* there will be little, if any, difference when directly comparing Rec.709 to a wider color gamut because life-like imagery doesn’t contain colors saturated enough to make a difference. You can see a dramatic difference though with using a wider color gamut for the rich colors used in animation and visual effects.

Just sayin….don’t expect your kids soccer match, weddings, family outings to the zoo, etc. that you shot in raw or log with your Red or Sony 4K movie camera to look any better if you have it color graded in Rec.709 or P3 by your local post house.

Not to get off topic but I can't believe this thread is still going strong... I almost never check it. Random.

On topic…..a question for any lurking developers. Right now, what is the better HEVC encoder….the HM or the x265? Or, for that matter, this puppy - http://www.vantrix.com/f265/

Off topic, I’ll need a few moments to load an appropriate pic. Hold please……

Good point.

But, to give the ‘studio’ part of the system a little break, the engineering folk would really like to be able to have available pro (reference) monitors (not so important for consumer devices) capable of displaying the entire BT.2020 gamut for precision color grading and mastering. These have yet to be built.

You can decide for yourself whether or not that is a legitimate excuse.

For consumer devices, you could have a 4KBD spec that includes accepting data encoded into the wider B.T. 2020 specification but, essentially just display an *expanded/bright* rec.709 gamut until the technology advances in the consumer space for complete BT.2020 coverage.

You're in the wrong thread if bickering is what you're looking for.

Default When will HEVC 2.0 be ready?

Anyone know of a roadmap for H.266 or whatever it will be called? Like to see it on the next disc format.

The mastering display color volume SEI message was recently added to HEVC which was proposed by Movielabs and based on SMPTE 2086. It includes metadata that specifies the color primaries and dynamic range of the reference display that was used to master the video (so that very wide color spaces can be used). As for Rec. 2020 reference displays I have heard that they will start to come out next year.

If 4K Blu-ray supports wide color gamut video I think it will include metadata so that it can be shown on current UHDTVs/HDTVs. My guess is that 4K Blu-ray will be as backward compatible as possible with the exception of HDCP 2.2 which might be a requirement.

The second version of HEVC should be officially released in 2 or 3 months. The second version will include 12-bit profiles, several features for wide color gamut video, and several features for HDR video.

It's too early to talk about a successor to HEVC. With the explosion of streaming media I expect the gap will be a couple of years shorter than the gap between H.264 and HEVC. But still...many years away.

In the meantime it would be worth paying attention to Xiph Daala which is a departure from DCT-based codecs. Depending on how it performs it may suggest the direction that future JVT codecs take.

I’ll vote for SHEVC (Super High Efficiency Video Coding) for it needs the addition of only one letter to all presentations, such as - https://forum.blu-ray.com/showthread...vc#post9208144

And for the developers themselves, it is a natural progression in nomenclature.

If there are 4K color critical monitors coming out next year with 100% coverage of BT.2020 gamut (analogous to 100% coverage of another gamut, namely P3, like with the PRM-4200, back a few years ago - http://www.noteloop.com/kit/display/...-4200-monitor/ which allowed for precise color grading (without the need for a DCI compliant projector)….then yes, not having BT.2020 supported in the 4KBD spec would be as you said “a defeat for consumers” and might I add, an unfortunately sad defeat.

Exactly. Just because the range is there, doesn't mean that the content will actually take advantage of it. It's hard enough telling people to not get excited about Sony's Expanded Colour on their Mi4K Blu-ray line (which, in real world viewing, didn't make a damned bit of difference to me), let alone new gamuts which will no doubt be advertised as THE GREATEST THING EVER* by the various hardware manufacturers. Folks will take those TVs home, put on their favourite soap and then complain that "it don't look no different!". Having sold TVs for many years, I've been on that merry-go-round more times than I can count.

*until the next greatest thing comes along
