HDR playback going live for Samsung Galaxy S8/S8+ users in latest YouTube app update

The latest update for the YouTubeapp (12.34.55) is enabling HDR playback on Galaxy S8 and S8+ devices worldwide.


The Galaxy S8 and S8+, as well as ahandful of other HDR-certified handsets, recently tapped into Netflix’sexpanding roster of HDR video content, but the latest YouTube app update seemsto have a more limited scope.


After installing the latest updateon our Galaxy S8/S8+ and LG G6 units, we discovered that the functionality isavailable only on Samsung’s phone. Playback at 1440p60 HDR is not perfectlysmooth on either the S8 or S8+ at this point, but this will likely be ironedout in future updates.


If you own a Galaxy S8/S8+ and wantto try it out, don’t forget to change the phone’s resolution to its highestsetting of 1440p (in case you’ve brought it down to 1080p for some reason), andupdate the YouTube app to the latest version (12.34.55). Also keep in mind that HDR-enabled content cannot be cropped to fit S8's display at at this point, meaning that you'll have to put up with pillarboxing for now.


Of course, you’ll also need to findan HDR video to play on YouTube, as not any old video can do, so here’s the onewe used for testing:

Indeed, although that may require a Samsung update first.

Dolby Vision HDR is hardware specific. It doesn't support just any phone with HDR. Not saying the S8's won't get it, but I think they won't. The S8's have a Premium Mobile HDR display, and it meets the standard from UHD Alliance for HDR content - per DisplayMate. They have a different spec than what Dolby Vision requires I believe. http://televisions.reviewed.com/features/heres-what-you-need-to-know-about-high-dynamic-range-in-2017 http://www.pocket-lint.com/news/138387-mobile-hdr-dolby-vision-hdr10-and-mobile-hdr-premium-explained

For Dolby Vision, it needs to support for Rec. 2100

Netflix supports both HDR10 and Dolby Vision, they just don't support the mobile HDR standard.

The largest hardware requirements are dynamic range and color gamut related, both of which the S8 AMOLED panel should be able to cover. What remains is LUT, decoding and possible license fees. All of which in theory can still be covered without hardware changes. But whether Samsung will... Yes I agree, that remains to be seen.

Working here, although most of the video labelled HDR doesn't appear to be HDR on Youtube.

The app still needs work. I compared the Sony 4k 60fps HDR glass blowing video on my S8 in 3 ways : A: YouTube app B: Chrome browser (forced desktop mode, YouTube app disabled) C: original video downloaded, played through Samsung's video player A wasn't smooth at 1440p and blacklevels were crushed, plus the perceived resolution was still less than method B played at 1440p. But yes, HDR works. B was smooth and more detailed at 1440p, a bit choppy at 4k (but better detail at 4k scaled to 1440p display). Better dynamic range and colors but still not the best. Method C is still mind blowing compared to the others. 4K (scaled to 1440p) 60 fps HDR smooth as a baby's b*tt, fantastic detail and amazing dynamic range and colors. You'd think that all the compression was already done when uploading videos, but the YouTube app (and to a lesser extent the website) still use too much overhead or use suboptimal code. Mind you, many of the HDR labeled (title) videos on YouTube will not actually play in HDR, as they don't use a supported LUT, or are simply HDR videos mapped to regular non HDR LUT.

Wow! 4K videos just look breath-taking on a 4K display. On Samsung's QHD+, the down sample still looks very good, compared to how iot looks on my iPhone 7+, sampled down all the way from 4K to 1080p. Everyone has gone 1440p standard now. Apple only gonna go FHD+ on the next iPhone is terrible for $1000+. The next iPhone is gonna be a joke, but it will likely be certified for Dolby Vision HDR which will help it look good. but a 4K video isn't gonna look as beautiful on it vs ho it looks on the S8's and the Note 8. Samsung for the win! You may not need QHD or 4K on a display, but when you get to watch breath-taking vids like this, if you odn't have it, you have no idea what you are missing. Watching this video on my HP (4K) and my Samsung QLED TV with 50% brightness is absolutely amazing! The colors are just mesmerizing!
