HDR10, Dolby Vision, and HLG: How does high dynamic range video work? | Upscaled

  • Published on Oct 12, 2019
  • With more content and compatible TVs available every day, HDR video is the best way to get amazing looking video in your home. But as we learned making this video, it's also a lot more complicated than it seems (and no we didn't master this in HDR). Add in three or four competing standards, and there's a lot to unpack.

    Basically Peak Brightness is the equivalent to Max Power in an Audio amplifier

    I like HDR in movies but can't help but feel it is revisionism

    Don't care too much about Dolby Vision or HDR+ though since most modern HDR-capable TVs can already process HDR metadata dynamically. Also, HDR10 does support higher Nits levels than 1000 Nits... and its a real pain in the neck to deactivate DV compared to HDR10. And before you ask why anyone would want that: if DV looks terrible on your display, you can't do anything about it. If HDR10 looks terrible on your display, you can on some players strip the metadata and finetune the luminance output to your liking, all the while preserving other HDR benefits like wider color Gamut. This can also come in handy if you have some older movies in HDR that look excessively noisy... this is not natural film grain, but comes from pushing luminance on the source material that wasn't meant to be pushed in that way. It's kind of like pushing luminance of a high ISO photo in post, there's only so much room for corrections until quality breaks.

    The HLG part confused me a bit. Are we saying the broadcaster is responsible for HLG, while HDR10 and Dolby are standards in the TV?

    Looks like you need to add HLG to your content, so that I can grasp the info

    Simply put: HDR maximizes your tv`s brightness, makes things look more vivid, by using a master copy which means more data which equals a better overall picture.

    I have a Samsung MU6100, which is a budget TV, and HDR content looks greyed and washed out. It supports HDR10.
    I don't know why Netflix or Amazon doesn't make HDR optional on its app.

    By sucking so I turn it off. If I wanted a dark screen I could not see what is going on. I would keep the TV off.

    Wait, you're telling me HDR isn't just an elaborate gimmick at adjusting your vibrancy, brightness, contrast, and saturation settings? People won't see much of a difference in anything, if they were never shown in person a side by side comparison. Most of my friends that don't own a HDR TV couldn't even tell a difference that they were watching HDR content on my HDR TV.

    Dolby Vision is a must for me now. Sadly I find myself scrolling through Netflix until I find a movie shot in Dolby Vision. I figure I have this new LG tv so might as well feed it the content it was built for.

    I'm in the market for a new tv but this vid was so frenetic (wavey hands, hurried speech, numerous camera changes) I couldn't watch it in the end. You need to calm down a bit.

    Mostly it doesn't. Because nobody actually follows the rules and just fakes HDR.

    Tell there's one standard there's no reason to adopt one I didn't buy a VCR until VHS had one as the standard I'll do the same when it comes to high dynamic range television also most broadcasters can't even broadcast in that format alot are still broadcasting in 720p so therefore even 4K televisions are still a little ahead of their time but yet we've also have 8K TV that are over kill so I just bought a 4K television with no HDR for now once we get a Winner in standard War then I'll buy a new TV

    I think HDR is overrated. While it makes daytime scenes look beautiful dark scenes always look too dark to me. I'd rather just regular 4K!!! And yes I own a 2018 HDR Samsung tv.

    When I watch 4k hdr content on Amazon prime my screen flashes white for a split sec every so often, would that be the hdr changing or not enough internet bandwidth?

    The negative Netflix app on Samsung TV has caused great frustration, some series are way too dark, even in a darkened room. You can try cranking up the dynamic contrast, but the only real solution, is an external player like the shield tv, and turn off hdmi uhd color on you tv. I think it is a great oversight from TV manufacturers and Netflix. And the loser is the customer.

    Great video. I like how you make things understandable. I love the HDR on my new Sony TV, but man, what a mess with the standards. What bugs me is that I never know what kind of HDR I am watching in my streaming content. Amazon Prime just labels it's content as HDR, but doesn't tell you what kind. Same for RU-clip.

    Wow, that was the most comprehensive description I know of. Thank you for making this video. Now. if you would only just quit using that ancient 1927 24fps frame rate which was chosen only to support recording sound on celluloid film, you guys would rock. Oh, btw, RU-clip does not have Telecine (3:2 pulldown) which the big streaming services use to smooth out slower panning and zooming shots.

    I think double vision is just a gimmick. Yes it looks nice and I like the little toggle that says double vision but it's just the placebo effect. Do truly watch Dolby Vision you need at 12 bit panel and there's no 12 bit panel out now. My three-year-old Sony has better HDR then most TV's in its category which have Dolby vision of this year.
