So this is the next gimmick the industry is going for.
I wondered what the next big thing was going to be after 3D and resolution whoring.
Apparently it's the colors.

>>57431864

This looks like one of those videos they continuously play as a preview on TVs and monitors that are on display at stores.
It's over saturated to hell and back, so it would make even the shittiest of displays look good, which it does.
>>
HDR doesn't actually make the images more colorful though.
>>
I don't understand something. How the shit is HDR supposed to improve contrast by increasing bit depth? You can display finer gradations of color since it's 10b of course, but how the fuck does that affect contrast? How is feeding your screen 30x 0 bits any different than feeding it 24? It's still the darkest value it can go to.

Is it just marketing shit for displays which come with better contrast, which could very well exist with 24bpc as well? I just don't see how a screen's black level or max brightness could possibly depend on the number of color bits you feed it. Is "HDR" basically more colors + some sort of minimum contrast ratio certification which a good-quality SDR screen could get too?
>>
>>57432188
It doesn't affect contrast.
You have to sell it to normies somehow though, so they try to market it like that.

It's funny how they advertise HDR. Like they'll show the non-HDR as a shitty, greyed out pícture, while the HDR version is just a standard picture with boosted contrast.

Gotta sell new TVs/monitors somehow I guess, since they have to wait for content creators to catch up to the 4k/8k meme resolution.

Displays have always been able to display what HDR's main advantage is. Shadow detail and avoiding blown out skies. That's always been an issue with the device recording it. HDR on new displays just add more bits for color gradation and higher contrast ratios due to light output on the display. But for just revealing shadow detail and blown out highlights HDR in recording terms is still something you can see on a standard display.

>>57432212
Yeah that's what I thought. Can 10b color really make that big of a difference though? I haven't ever seen proper 10b content on a 10b screen, but other than potentially decreasing banding issues (which aren't really a huge deal anyway) I can't imagine how it would have some sort of huge impact. Most people apparently can't even tell 720p from 1080p or 1080p from 4K, are they really going to notice 2 extra color bits per channel?
>>
>>57432303
2 bits are a huge fucking deal. It means 4 times the color resolution.
It is apparent mostly in video games, but none of them support it right now apart from shadow warrior 2 (I think).
The ability to display skies is much better, and shadows and dark areas are much more defined.
Thanks to the ps4pro we will see a lot more games with 10bit.
I think the change is necessary and good.
No longer will gradients look fucking retarded.
>>
>>57432361
SW2 does have the option, yeah. I have to see it for myself, I know we're going from 256 to 1024 values/color, but I haven't really seen any glaring issues with shadow detail and skies, even in games, as long as you're running them on a decent monitor which doesn't crush blacks or show clipping in the whites.

HDR is not about increasing the bit depth, it's about increasing the dynamic range. They're related but ultimately orthogonal.

>You can display finer gradations of color since it's 10b of course, but how the fuck does that affect contrast?
HDR is *not* the same thing as 10-bit SDR (as was used with UltraHD or Hi10P content). HDR is about increasing the brightness range you can represent, from 0.1-120 to more like 0.001-10,000 nits

>Is it just marketing shit for displays which come with better contrast, which could very well exist with 24bpc as well?
Pretty much. Brighter whites and darker blacks. That's what HDR is all about.

Note that youtube adding HDR is actually a bigger benefit than just increasing contrast: Since HDR sort of implies BT.2020, we're also getting a much wider color gamut out of the box.

No, because they were focused on making higher resolution panels with shitty contrast because nobody gave a shit about anything except how many "K's" it had.
>>
>>57433798
>which supports a color gamut outside the standard 16 million colors.
You're thinking of bit depth. A monitor can support 10bpc color but that doesn't mean it has a wide gamut. Likewise there are plenty of 8-bit monitors with a wide gamut.

In either case, no, you won't notice any real world benefits.

Unfortunately I don't think this is the case. An HDR rated display can have any contrast ratio.

But yeah it is confusing and the facts are fudged. But what consumers need to know is that HDR video and good contrast ratios go hand in hand, because you need good contrast to take advantage of HDR video.
>>
>>57434655
HDR is basically a marketing label used to mislead the public into buying “HDR” LCD panels. It's a bait-and-switch: Show people fancy OLED tech at conventions, get them hyped about OLED, sell them shitty “dynamic HDR” LCD panels instead.
>>

>HDR is not about increasing the bit depth, it's about increasing the dynamic range. They're related but ultimately orthogonal.

Yes it is, depending on which technology named HDR you're talking about.

>Pretty much. Brighter whites and darker blacks. That's what HDR is all about.

That's static contrast ratio.

>>57432996
HDR video is 10 bit
We've always had high contrast displays, and we didn't call them HDR. You could for example, have an OLED display that can show perfect blacks and whites as bright as the sun, and it only displays 8 bit video.

https://en.wikipedia.org/wiki/High-dynamic-range_video

>>57432243
That's the best simulation you can present on an SDR display though. Black is actually dark grey, and white is bright grey. Your eyes just adjust.
>>
>>57433857
>yeah the backlight thing, which isn't native and looks like shit, it's just localized dynamic contrast

Compared to what? OLED is a good while away from being cheap and long lasting.

Then again the active matrix backlight with a decent resolution is a long way from being cheap too.

Really? It's a pretty huge deal.
>>
>>57434736
>Yes it is, depending on which technology named HDR you're talking about.
I'm talking about the term `HDR` which literally stands for `high dynamic range`, and in this context refers to SMPTE ST.2084 and ARIB STD-B67

>That's static contrast ratio.
Sort of. The point of HDR is not just pushing the static contrast number up, but also increasing the overall envelope (i.e. brighter brights, not just darker darks)

In a way, static contrast ratio is a number that tells you almost nothing about the real black/white points. For the purpose of clarity it's best to focus on the concrete numbers rather than their ratio.

A typical, high-quality SDR display has a black point of like 0.1 cd/m2 and a white point of like 100 cd/m2, giving you a contrast of about 1000:1

A high-contrast SDR display might have a black point of 0.001 and a white point of 100 cd/m2, giving it a static contrast of 100,000:1. But it's still not HDR

A HDR display might have a black point of 0.01 and a white point of 2,000 cd/m2, giving you a static contrast of 200,000:1 but a greatly increased dynamic range (meaningful brightness spectrum).

>HDR video is 10 bit
That's an implementation detail, really. You could have an 8 bit HDR video, it would just be lower quality. You could also have a 12 bit HDR video. (In fact, the spec allows for the latter iirc)
>>
>>57432303
You can make up for minor differences in bit depth by dithering heavily, but the problem with dithering is that it's extremely expensive to encode.

(This is why 10-bit encoding is more efficient than 8-bit encoding on anything with gradients - you don't have to dither)

So really, while 10-bit isn't strictly necessary, it's simply more efficient bit-wise.

Fuck off, the `HDR` from photography is pure cancer and has nothing to do with actual dynamic range. That's just shitty faux-HDR tone mapping.

This is about true HDR, end-to-end; which requires a HDR camera, HDR encoding and HDR display. No tone mapping involved.

LCD's are able to display higher nits than OLED at present. But because OLED's inherently have supreme contrast ratios to begin with they got the HDR label anyhow. I think the intended nits is something like 5000 nits which is like sunlight blinding. But all LCD's out there can only go up to 2000 at the most I believe. A prototype had 4000.
>>
>>57438189
Oh! The offshoot of this is that the power usage of TV's has to be kept in check (especially in countries trying to get power usage down like those in the EU). Generating brighter images requires more power obviously so it's a push/pull problem to get TV's with low power usage to meet the requirements in certain countries vs. trying to make the image brighter.
>>
>>57438189
The problem with LCDs is that the brighter the backlight gets the more difficult it is for the pixels to block the light completely which can ruin your blacks. Even if the backlight was managed dynamically in scenes that have both very bright and very dark areas you would need the backlight to be sectioned into grids to get the effect, and even that wouldn't be perfect in some situations.

OLED has the benefit of producing light from the pixels themselves, which means blacks are pure, but the added problem is that it is more difficult to create much brighter pixels. I think some panels have a dedicated white subpixel to help in this.

We are probably going to see more clever subpixel designs in OLED to overcome the brightness issue before LCD can control its black issues.
>>
So, if I got it correctly to display HDR both the screen and the media itself has to be compatible.

Doesn't this imply regular content would look relatively dull on a HDR screen? And wouldn't this mean HDR would look blown out on a regular screen?

Why can't they make HDR screens natively convert media into the HDR range?
>>
>>57438421
>Why can't they make HDR screens natively convert media into the HDR range?
But they will. It just won't be perfect because it will be done in software.

Also, what about regular images?
Is there an HDR image format for the internets on its way?
>>
>>57438445
Not perfect how?
>>
>>57438461
Most likely it would just adjust the levels dynamically in an attempt to expand the range but it will be limited in how much detail was lost in the storage of the video and the algorithm.

In proper HDR video effort will be made to retain details in the very dark and very bright areas so that they can be displayed correctly.

>So, if I got it correctly to display HDR both the screen and the media itself has to be compatible.
Pretty much, yes

>Doesn't this imply regular content would look relatively dull on a HDR screen?
Yes.

>And wouldn't this mean HDR would look blown out on a regular screen?
Well, fundamentally this is impossible to display. So it depends on what adjustments you do to turn HDR into SDR:

- no adjustment, just display the HDR image as if it was SDR: image will look extremely gray and bland
- hard-clip out-of-range values: image will be will of awful clipping artifacts as if it was constantly blowing out the sensor
- tone-map the brightness with a nonlinear curve: will look sort of like SDR content normally looks, with not much loss. (but slightly distorted colors)

If you use a media player like mpv which is HDR-aware, it will do the third by default. If you use any other media player, it will look like the first.

Oh, also, if you know the HDR signal peak then you can do a much better job of adapting the brightness range. Normally this is known from the image metadata (including on youtube), but this clip in particular had broken metadata so I had to tag it manually. After doing so, the top is what the “tone-mapped” result looks like.

Also, there's a third possibility for what you can do with the values: You can linearly stretch them to your device's brightness range instead. The bottom pic shows what that would look like.

>So going from 8-bit to 10-bit does not add more colours?
Going from 8-bit to 10-bit pretty much just makes gradients smoother. Bit depth and colorspace have almost nothing to do with each other.

That said, HDR, in practice, *does* make the images more colorful because HDR is usually paired with BT.2020 which is a much wider colorspace than BT.709, allowing you to represent significantly more saturated colors than before.

Here's a comparison on one of the youtube clips. Top is the tone-mapped HDR image, bottom is the `SDR` image for comparison.

Btw, these images will most likely not look correct on your monitor because they're rendered for my calibrated wide-gamut monitor in particular. So use them for a comparison between the two, but don't use them as an objective reference.

Because nothing else was out of gamut? Do you even understand what a gamut is? Here is a page from the ITU-R Report BT.2246-2 giving you an example of some real-life objects and their associated color spectrums.

Everything inside the smaller triangle will look the same in both pictures. Everything outside the smaller triangle has to be clipped for the SDR (BT.709/HDTV) release.

Have you never noticed how artificially limited the colors of your display are compared to nature? Go find the reddest object you can find and compare it against #FF0000 on your display - it will look extremely orange in comparison.

Same is happening with the skateboard. It's red in real life, but BT.709 can only represent up to deep orange. That's why it has to be clipped for the SDR release (bottom image), but it can have its true color in the wide gamut version (top image)

Btw, pic related is a 3D comparison (intersection) of the gamut in the HDR test frame I presented here in >>57440727 (top version, solid) versus the gamut of the BT.709 color space (wireframe)

Everywhere where the original image exceeds the gamut of the wireframe, you would get clipping in the SDR version since the gamut has to be desaturated to fit. In the BT.2020 version, no such restriciton applies.

Nothing in >>57441039 was “boosted”

The measurements were derived by using a carefully tuned xenon lamp with the spectral energy distribution close to that of the midday sun, and measured using a high quality scientific imaging colorimeter worth many times your house.

The values displayed are nothing less than an accurate indication of the gamut of real life. This was known 70 years ago, the original television sets were all wide gamut.

Then the jew came along and decided to desaturate all of the primaries so they could manufacture TVs for cheaper instead, and decided everything being bland and orange would be fine for the average goyim. Thus originated the BT.601 colorspace.

What you're seeing is nothing but the colors of reality finally being unlocked, which were stolen from you for 50+ years by greedy phosphor manufacturers.

Panasonic uses a honeycomb mesh with an array of local dimming LED's to achieve this. The mesh prevents halo's around bright objects apparently and supposedly works rather well. I dislike LCD because of the ghosting I sometimes see on fast moving objects. I have a Panasonic plasma (A midrange G20 from 6+ years ago). It has issues and I am looking to get an OLED as my next purchase once the prices drop to a more reasonable level.

False.

Samsung has shown interest in potentially, for the TV market only, making individually addressable QDLED backlights.
For now, EVERY samsung QD display is using a single plane - not individually addressable backlight 'pixels'
Technically, even the older 9 zone 'local dimming' backlights of older Samsung LCDs is better.

Sony and LG are still to date the only companies who have made displays with individually addressable backlighting

There are two competing standards

One is SMPTE ST 2084, which is by far the more common one (used in UHDBD, youtube and pretty much every test clip I've seen so far). It's being pushed by Dolby, Samsung etc.

The other is ARIB STD-B67, which is doesn't seem to be as widespread, but it was mainly being pushed by ARIB and BBC.

ST 2084 introduces the PQ (perceptual quantizer) transfer function, which is a fairly complex, multi-segment function tuned to match the human visual response. This allows it to get the maximum amount of “quality” out of any X number of bits, but it requires a more complex decoder logic; and it also means that if you play it back on a ‘normal’ screen without appropriate conversion logic it will look like cancer. PQ is also defined on an “absolute scale”, meaning that a PQ-encoded value of Y will *always* map to an absolute brightness value.

STD-B67 introduces the HLG (hybrod log-gamma) transfer function, which is a much simpler, two-segment function. Below 0.5 it's a normal gamma curve (as with legacy systems), and above 0.5 it's a log curve (as often used by cameras, see e.g. Panasonic V-Log). Unlike PQ, it's not mapped against an absolute scale but against a relative scale (so a HLG-coded value of 0.5 will always map to your subjective reference brightness, which depends on the display), with everything above that being considered a super-highlight. Also unlike PQ, if you naively display it on a ‘normal’ screen, it won't look nearly as bad. It's also easier to implement.

The main benefit to PQ is the increased coding efficiency. The main benefit to HLG is the fact that it's intrinsically scaled to your subjective reference brightness, which makes implementation easier still.

Pretty much, although it only goes into the super-brights. Another way of thinking about HLG is like the brightness equivalent of scRGB, by simply allowing you to go “above” 255, you can encode super-brights and out-of-gamut colors for display devices capable of representing them.

(Meanwhile, standard gamut and standard-brightness displays would just soft-clip to the range they can represent)
>>
>>57446949
Well, you're being strongly misled in that picture. If you actually want to understand any of this, I recommend staying as far away as possible from any consumer presentations (especially these nonsensical “comparisons”)

HDR vs SDR affects _nothing_ but the image brightness range (“dynamic range”)

What you are confusing for HDR here is the fact that the HDR generation of TVs *also* comes with improvements to the gamut, bit depth refresh rate and so on. In particular the “HDR10” standard, besides ST2084 (“HDR”) gamma, also mandates the rest of BT.2020 specifications

But just as you can have a HDR standard-gamut display, you can also have a SDR wide-gamut display. It's very important to distinguish between these two concepts for that reason.

>I can understand the deeper blacks, but like wtf why can't your tv just display the colors that are 'missing' ?
The reason why standard gamut displays can't display wide gamut colors is simply because they can't physically generate the required frequencies of light. The LEDs in the backlight itself simply don't emit those parts of the spectrum. When you buy a wide gamut device, you're buying a device that uses different (more expensive) phosphors that enable it to represent more frequencies.

The reason why SDR displays can't display HDR images is because of simple mechanical limitations on the output brightness range. Even if you turn up the backlight brightness, your dynamic range won't go up because of imperfections in the liquid crystal filtering. You can't have a 0.01 cd/m2 black pixel and a 1000 cd/m2 white pixel on the same screen with conventional LCD tech. HDR displays use more expensive backlight solutions that are capable of doing this.

>>57447046
That has absolutely fuck-all to do with anything
>>
>>57446949
>I can understand the need for a better camera to capture all the light, but why would I need a more expensive tv to display the video from the camera ?
Imagine trying to display the output of a full-color camera on a black-and-white TV.

At best, you can invent a good algorithm for mapping the output of the camera into black and white hues, but at the end of the day, you're limited by what your display can output just as much as you're limited by what your camera can capture.

Without an upgrade to the TV set, you're simply never going to be able to experience a full color picture on your black-and-white screen. It's fundamentally impossible.
