It's because he's NOT "nitpicking". 😁

What you describe is the opposite. That is dynamic range compression - you take a huge dynamic range in the nature(requiring more than one pic at different exposures to cover it) and squeeze it into a much smaller dynamic range that a TDR - tiny dynamic range monitor can display. This is also decreasing the contrast, not increasing. Contrast is difference between darkest and brightest parts of an image and all the fuss with the multiple frames is because camera will clip either shadows or highlights. HDR in this video is actual high dynamic range, where the display will sear your eyes with highlights and retain detail in shadows simultaneously.

The photography HDR is different from TV media HDR. What failed to be mentioned was that in HDR10 standard, the 10 refers to the 1000-nit max peak brightness. That refers to physically how bright the screen really is, which you really can't control in printed photos (unless you intend to set it on fire lol) In 1000 nits, it's equivalent to a 292-lumen light bulb (It's not the wattage of a bulb that determines how bright it is, but the lumens). HDR standards define how bright the screen will be. Dolby Vision requires a 10,000-nit, or 2,919-lumen, peak brightness, and HDR10+ is 4,000 nits (1,168 lumens). HLG brightness is dependent on your display, as it is also backwards compatible with standard dynamic range (SDR) screens at 100 nits. Photography HDR is designed to get the most detail by taking multiple pictures within an "exposure bracket" and then combining them. The only exception to that is data that is taken in RAW format (which file type differs by camera manufacturers. A Canon Rebel T6, also known as a 1300D depending on region, uses the .CR2 file extension for its RAW format). This really actually blends both ideas, only because the camera takes the picture, skips all processing, stores that data, and notes the camera settings so it can be displayed right. It's all uncompressed. Here's an example to understand it. In editing, a photo taken accidentally in black-and-white can be easily switched to full color in as little as one click because the photo actually WAS taken in full color, and is stored that way. But the camera made a note that it is to be displayed in black-and-white instead of all its color glory. The same idea goes for white (color) balance, and if you underexposed an image. It can work with overexposure, but nowhere near as much as underexposure.

TJ West this it's the best technojargon I have ever read. Gifted man you are.

TheEpere15 haha thanks mate.

NO, It's high dynamic range. It has a bigger color palette than normals

@@generationedge6699 You missed the sarcasm. (There actually is such a thing as "HD Radio", essentially an all but failed attempt to bring AM & FM radio into the digital age.)

@@richellebrittain2127 Oh I get it. Thanks for correction

It's because movies and TV and generally only 24-30fps, HDMI 2.0 can handle that just fine. The manufactures probably don't even think about people hooking their PC up to a TV.

superkirk11 - there's a loyalty fee for HDMI. Doesn't really explain why they would choose that rather going using DP which is free.

Weird didn't know that about HDMI. Probably because somewhere, someone high up in these businesses, (or a relative or close friend) stands to make some money off of HDMI royalty's.

The upcoming Big Format Gaming Displays (BFGD) will allow you to game at 4K 120Hz on a TV size monitor through Display Port connection. The Asus model is the PG65. Just be patient.

As long the BFGD is affordable...

I'm not sure how KZfaq will do it, but I know that in the movie business, there has to be two different color grades for each color space / standard. 1 color grade for the REC 709 color space (standard), and another grade for the REC 2020 color space, to grade for the up to the 1000 nit brightness / darkness differences.

Part of the reason HLG was invented was to create a backwards compatible grading system, essentially an extension to SDR, so they wouldn't have to put two separate grades into broadcast signals. Basically everything other than HLG & HDR10 is an enhancement of HDR10.

Kind of late... Even though HDR color container is Rec.2020, movies are mostly graded in DCI-P3 gamut before being put in the HDR container and later converted to Rec.709 SDR if needed for a web-streaming service (because internet browsers use Rec.709). Compatibility is based on service provided, for instance streaming services usually offer multiple encodings including Dolby Vision, HDR10+, HDR10 and SDR in case the end user's device doesn't support one or the other. For local medias like BluRay, if the consumer does not have compatible equipment, they cannot legally play the content due to lack of any fallback mechanism, unless the digital file is ripped and tone-mapped to SDR.

oled hasn't infinite contrast.

It doesn't have infinite contrast, but since it has the darkest blacks you can get on a TV, and each pixel produces its own light, very high contrast pictures won't have a "bleeding" effect, and the darker blacks give them some advantage, because they're able to have very high contrast, even when they don't have the brightest peak whites.

Tonatiuh Valenzuela consumer microLED displays will be very interesting.

I hope this will help you: In a nutshell: contrast ratio is the ratio between on and of, HDR is the resolution in between the two. While not independend, solving one problem does not solve the other. Long answer following: Standard Dynamic Range uses 8 bit per Color. 8 bit can represent 256 values, so 0 or of is the lowest/darkest, 255 the brightest value. This means that you can represent 256 different levels of brightness. This is not bad, especially if your Picture is relatively dark overall, like it is on an traditional TV or a cinema screen. The 256 Steps are close together, so they are sufficient for an undisturbed experience. But as the TV gets brighter (~100 nits traditional, ~1000nits in current high end), these steps get larger, and might become noticeable. Therefore, we now use 10 bit (HDR10) or 1024 values per channel, making the steps sufficiently small even for very bright pictures. The contrast between perfectly off and 1000 is infinite, but so is the contrast between off and 100. The contrast is not all when it comes to quality. The point of (almost) perfect black for OLED is, that you can represent the small steps in the very dark regions. Lets say, your Standard - backlit - Display lets through a minimum of 10 nits (completely arbitrary number), even when set to the darkest black. You notice this when your phone or pc starts on a black screen, but is actually grey. Any value between 0 and 10 will look identical, losing information in deep shadows. You also want to factor in, that each pixel is made out of three colors. Perfect red would be if you turn of green and blue completely. Due to aforementioned "backlight bleeding", this is not possible on traditional displays. you therefore will always have "washed out" colors to some degree. These are the reasons for OLED, and for HDR in general.

Adrian Burmester great explanation, this should be added to this video.

It has HDR 10 and 10+ No Dolby Vision and you don't need it.

english please for us non-intellectuals

Or add two more 8bit channels, Contrast and Brightness and make it something like RGBCB. That way you can set it dinamically per pixel :D It would take A LOT more bandwidth but okay

yeah, maybe with prophoto rgb, uncompressed footage and dsd audio :)

FYI Dolby vision works upto 12 bit display, it actually adds in more data for higher range colour.

Even though i'm not quite sure if you are serious, let me answer that. 16bit would mean 65536 grey values per color channel, that to the power of 3 equals 281.474.976.710.656 different values in RGB. Standard dynamic range is the well known 16.7 million value. So yeah, you will not ever be able to see that fine differences. Assuming your point is that we can have fixed values for each brightness, so you never have to touch display intensities again. This is not how our eyes work. we adapt to different brightness, so as soon as you exceed a certain threshold, you will adapt to the bright and loose all information in the dark. There is simply no point in cranking the bit depth that high up, as it would never be used. Even if you definetly want to stay on fixed brightness levels, the very bright values are very, very scarce, so you would carry mostly empty bits

If it says "HDR" but nothing else, it's 99.9% certain to support only HDR10. Except for HLG (which exists largely for backwards compatibility in broadcast & similar signals and is too new to be common yet), all the other formats (DV, HDR10+, etc.) are just extensions of HDR10.

@@richellebrittain2127 thank you for your answer. 👍🏻

who knew reality didnt have scene changes.

OLED and HDR is magic. 99.99% of LCD TV's can't show HDR properly (100% of the cheap ones can't).

Don't tell me they're working on Smell-O-Vision again. 🤣🤣🤣

Depends on the TV. I didn't have to enable anything on my TV (TCL 43S517 with HDR10 & Dolby Vision); my 4K Blu-ray player (Sony UBP-X700) requires you to turn on DV in the settings for DV content, otherwise it's just HDR10.

Good question, my guess , new tv
