imagic should have simply started a thread about the reason streaming was important to him and made no mentioned of Blu-ray. Using “Giving Up on Blu-ray” as a thread title in a supposedly “Science” oriented forum just smacks as a oxymoron.

I should have pointed out that AV Science Sales and AVS Forums are two different companies.
And that was a point I was trying to convey to him in one of his original threads. Evidently, being "cool" and convenient has gained priority. I think he ended up moving to a 65" Samsung plasma, but I haven't read his more recent posts.

It's stupid to have two different versions of HDMI 2.0. Potential confusion could turnoff potential customers.

Just call them 2.0 and 2.1.

It's not like they haven't done this before with earlier versions. You had 1.2, 1.2a, 1.3, 1.3a, 1.3b, 1.3b1, 1.3c, 1.4, 1.4a, and 1.4b.

Am I correct in thinking he does not have a projector? I seem to recall that he uses a TV. Still BD will provide a better image even on a TV.

Is 4k BRD only for projectors?

If they want any kind of volume, they better cater to smaller screens. The median in the US is around 40 inches?

4K is for everything... even PC monitors. Pretty sure its going to be on everything... even smartphones (quite a few are already 2K since early 2014).

No. Just giving my reasoning on why he (imagic) maybe fine with streaming. Streaming looks pretty good on a small screen. Blow it up on a big screen and the image really starts to drop off.

It's more like support for REC2020 plus metadata to accurately remap the color points to reproduce a true P3 and REC709 gamut. As far as HDR goes, it's a ways off in terms of us getting meaningful content encoded for it. From what Joe Kane has talked about on the subject, there will need to be a way for all of these HDR technologies to be "converted" to a single language that all HDR capable displays can understand. Plus there still needs to be a proliferation of displays that are actually HDR ready.

But, we don't know anything 100% as of yet. It seems SMPTE 2086 + REC2020 will be how UHD does multiple color gamuts though. HDR is still a bit tricky it seems when it comes down to implementation.

You are right, I stop looking for rational when people push 8" phone displays to 4k but marketing drives 95% of the people.

They handle three different gamuts for display compatibility (almost no rec2020, a few DCI, mostly rec709 today). They will master in DCI as that's what they have to deliver to Digital Cinema, and they will switch to rec2020 whenever UHDTV is broadcasting and requires it, which won't be until 2020 if they stick to their optimistic roadmap.


By then, most high end displays will handle DCI (I suspect most mid to high end projectors from Sony/JVC/Epson will from the end of this year). Then maybe by 2020 we'll have some consumer displays able to display such a wide gamut.


I'm fine with DCI for a while, as long as the standard is ready for 2020. I'd rather have them increase the disc size asap to the BDXL max (for UHD Bluray) of 100Gb and use less compression, so that we're not forced to double dip with poor initial releases or movies on two discs.


Re HDR my understanding is that they will have a mastering HDR standard which will be compatible with all three HDR end formats.
So it's pretty straightforward: DCI/HDR standard for mastering until 2020 or so, then rec2020/HDR standard. Displays will use this common base according to their capabilities.

To be clear, there has been no standard officially made public yet. These standards tend to exist long before the general public has any sort of access to them, that said it seems a standard does exist, even if not entirely finalized or ratified. Enough for Panasonic and BDA representatives to execute/speak authoritatively to them.

+1.

As far as HDR is concerned, it doesn't seem to be compatible with projection. Not only is it difficult to do, but who needs it. Do you really want to see the brightness of a bare light bulb while you are watching a movie at 15 FL? It will hurt your eyes.

What about scenes that show both outside and inside at the same time, that may need HDR? Well if you take a still picture with HDR settings, you take multiple pictures with a set of different exposures - and later combine them into 1 picture that combines the regions with proper exposure. But the idea is to compress the wide dynamic range of the source into the smaller dynamic range of the print or display. Not to just capture the wide dynamic range of the source.

I just don't see HDR as important.

It's a lot more complicated than that, and further, don't confuse photographic "HDR" with the HDR we're talking about ala Dolby Vision, SMPTE 2084, etc. I haven't had a chance to read through this but browsing through there's some interesting info on how "HDR" for video production works:
http://www.dolby.com/us/en/technolog...hite-paper.pdf

Another thing to remember is that current cameras can capture upwards of 14 stops of dynamic range, that's over 10,000:1 (16384:1), but digital cinema is only capable of 2,000:1. HDR, as described in the above Dolby white paper is more of a way of mastering content to work on displays with a wide range of dynamic range capabilities. So why wouldn't it be the case that a JVC, with 350,000:1 dynamic range capability, couldn't use the HDR Metadata to reproduce the image differently (better) than a standard, 2000:1 DLP projector? And given that information was baked into the master, by the content creator, isn't that a more accurate way to do it?

But regardless of who he is, do you really want the government getting more involved and taking more control of the Internet which is what is going to happen? I don't want to see it become a utility which in essence is what it will become and the administration is refusing to even reveal its 332 page "Net Neutrality" plan to the public until after it has been voted on. lol Sounds all too familiar.

As opposed to what, letting the big telecom companies get their way by lobbying Congress?

Locking out startups which can't afford to pay Comcast to not throttle them?

There's generally a low opinion of big telecoms for a good reason. They have often acted against consumer interests. Unless you work for or is a shareholder, why would any individual want them to get what they want?

And given that information was baked into the master, by the content creator, isn't that a more accurate way to do it?
DCI requires a minimum of 2000:1 on/off CR. The Sony's and newer Barcos capable of much greater, but house safety lighting is the limiting factor for dynamic range in exhibitor theaters - unless you want to operate at higher average light levels.

I'm refering to projectors (watching movies), not TV displays. You watch movies in a darkened room, and a 1000 nit bright area in the image would to "hurt" your eyes if you are watching at the current SMPTE recommented standard.

Now sure, you can leave everything the same, and have glints off of cars, and light bulbs show up at 1000 nits in a theater, and it's going to look like someone on the screen is shining a flashlight at you.

Now for watching sports - you may want brighter - but most sports are well lit, or are outside, and do not have a large dynamic range.

I'm all for recording masters with as much fidelity as possible to ensure everyting is captured. This is no different than with movies captured on film negatives, which have much more exposure latitude than the movie print.

Regarding the JVC, won't the (UHD-BD 2.4 gamma) 10 bit video (and potentially later 12 bit) increase the dynamic range of the recordings?

With the new UHD-BD there are some things I'm really looking forward to, like higher bit depth for color. Next is wider color gamut, although, I'm not sure it its going to matter much, time will tell.

As for HDR, I don't see the need (for projectors), but I could be wrong on that too. Just my 2 cents.

There's generally a low opinion of big telecoms for a good reason. They have often acted against consumer interests. Unless you work for or is a shareholder, why would any individual want them to get what they want?
There is a low opinion of the government in general too. And the administration is going to fix it just like they have fixed the debt, spending, jobs, immigration, health care, and fight on terrorism? lol There are much better solutions to the situation than "Net Neutrality" (which isn't what it says on the surface) and I don't want to get into a political debate. However, when Dan brought it up, just wanted to make a brief point. Let's stick to UHD Blu.

Question Will Higher Bit Depth For Color Really Make A Substantial Difference?

I'm refering to projectors (watching movies), not TV displays. You watch movies in a darkened room, and a 1000 nit bright area in the image would to "hurt" your eyes if you are watching at the current SMPTE recommented standard.

Now sure, you can leave everything the same, and have glints off of cars, and light bulbs show up at 1000 nits in a theater, and it's going to look like someone on the screen is shining a flashlight at you.

Now for watching sports - you may want brighter - but most sports are well lit, or are outside, and do not have a large dynamic range.

I'm all for recording masters with as much fidelity as possible to ensure everyting is captured. This is no different than with movies captured on film negatives, which have much more exposure latitude than the movie print.

Regarding the JVC, won't the (UHD-BD 2.4 gamma) 10 bit video (and potentially later 12 bit) increase the dynamic range of the recordings?

With the new UHD-BD there are some things I'm really looking forward to, like higher bit depth for color. Next is wider color gamut, although, I'm not sure it its going to matter much, time will tell.

As for HDR, I don't see the need (for projectors), but I could be wrong on that too. Just my 2 cents.
I found it interesting that you're looking forward to higher bit depth for color. Already, today with 1080p, on my displays I can view a scene of a salad bar or a bowl full of fruit, for example, and each vegetable or fruit item looks precisely like the real thing that I can grab from the refrigerator. Broccoli, for instance, from the rich dark green of its flower, to the way its light green stalk gradually transitions to white, could not look any more real in scenes from a salad bar than it does on my dinner table. With color reproduction already at such a high level of accuracy, I'd really like to know how increasing the color bit depth is going to make such realistic color reproduction, any more real.
