4k hdr questions on YouTube - Sony Xperia XZ Premium Questions & Answers

yesterday i could watch 4k hdr 60 on YouTube but today i can only play 1080 hdr 60 . do you haven meet this question?

When YouTube first launched HDR on mobile, in tandem with a 4k 60fps, the playback was extremely choppy(frames would be dropped). I believe they pulled 4K 60FPS HDR for awhile and are just staying at 1080hdr for now.

I concur. I have sent a complaint to YouTube and I believe many others have about 4k and even 2k being extremely choppy/ audio desync with HDR footage. 4k 60 is still perfectly fine though. I watched a few 4k 60fps vids to confirm today

Is it possible to get 4k60 HDR back by installing previous version of YouTube app?

No, the 4k 60fps HDR option is controlled server-side.

It was unwatchable anyway.

I got a few to work, one was in 50fps 2160hdr and worked fine. You tube issues.

No Youtube 1440p 60fps option?

Is anyone able to get 1440p 60fps videos working on youtube? I don't have the option on my Youtube app (latest version). I confirmed that the videos I was watching had the 1440p60 option on my laptop. VZW SD820 S7.
Also, does anyone else's video freeze/stutter when watching 1440p 30fps videos in YouTube? Sometimes the WiFi drops out for a sec too.
I am on the latest WiFi-fixed OTA.

HDR Video Playback Discussion Thread

Hi.
I got a Tab S3 2 days ago.
I've tested with MX PLAYER all heavy HEVC HDR videos, 10 bits UHD 2160p @60fps, and of course all other formats and bitrates.
EVERYTHING WORKS GREAT. All in HW or HW+.
Even the AVC h.264 UHD 2160p @60fps "Big Buck Bunny" works perfectly and fludly in HW+ (jonathonalexander told it didn't work fluidly???).
This Tab S3 is a must!
Also tested European version of Galaxy S8 with Exynos 8895 and it's able to read excatly the same video files as Tab S3 with absolutly no jitter.
Both Tab S3 and Galaxy S8 claim to work HDR file formats and it's true.

while you're right that it "works" in HW+ mode, it appears that MX player doesn't support HDR10 playback. it's easy to test if you play the same file in stock S8 video player which has no problems with local HDR playback. in fact, i wasn't able to reproduce HDR in any available 3rd party players.

Do you mean that MX Player can't reproduce the wider color space of HDR10 video files?
Unfortunately I was not able to make many tests on Galaxy S8 because it wasn't mine. The owner has only installed MX PLAYER which was working very well and we didn't test native S8 video player.
Question: is it the same player as TAB S3? (this one's version is 7.2.81 in French TAB S3)
TFor information there's only one video that this Samsung player can't play the video but only sound track: LG_4K-View-the-Felling.mp4
This video is played by MX PLAYER without any problem.

like i said, playing the file itself is not a problem but looks like MX doesn't pick up any HDR metadata so you're not getting the proper contrast range and luminance levels in specular highlights along with wider color gamut.
edit: i looked through the thread but didn't see the answer: does MX support HDR metadata at all?
Samsung tells that S8 and Tab S3 are HDR capable, is it true or not?
On my Tab S3 I've tried HDR videos from demos UHD 3D website with native Samsung player and Mx Player, and to tell you the truth I didn't see any difference...
So which player should be able to play HDR videos with visible difference?
Who wants test HDR capability, download these videos

on S8, native video player definitely supports HDR metadata. MX has issues with some HDR files (as in, doesn't pick up the metadata).

those look great and play in HDR in both native and MX player on S8. however, i can only speak for Jazz demo since i don't own any Dolby Vision equipment and while the Dolby ones do look HDR i'm not entirely sure if they look right. not sure why would Dolby HDR be supported on S8 to begin with either.

which decoder you have tried?
HW decoder doesn't work either on such videos?

I have asked this as you have mentioned that MX doesn't pickup meta data.
So, what's the exact issue?
can you add some snapshots?
If you can add more info, it will be better. I will forward the issue to our devs team.
I can confirm that my s8 plus exynos version can play HEVC 1080p 10bit HDR in HW and HW+ mode on mxplayer. Also played it in stock player and couldnt find any difference between both apps. Seems to be working well with HDR in both. Also played a 12bit 720p HEVC video but Mxplayer could only play it in SW mode.
Havent tried 4k yet.

i'm not sure how to submit this info to you.
video players (on Galaxy S8) behave the same way as HDR capable TVs pretty much, they boost brightness and contrast once metadata is detected. however, there's very little technical data provided regarding HDR capabilities of these mobile screens/devices. officially, Samsung only supports their own HDR10+ format which operates with dynamic metadata but there're no HDR10+ videos in the wild (i'm not entirely sure about this either) since it's new and targeted at streaming resources. most (all?) of the files out there are HDR10 (like that Jazz demo posted above) with static metadata only but the phone has no issues playing them and display proper HDR. why files marked as "Dolby Vision" "work" i have no idea either.
i tested MX player with random files and few didn't boost brightness and looked non HDR while stock player was able to reproduce HDR.
I can understand the how it will look with / without HDR.
In general the stock mediaplayers are based on mediaplayer api. So, technically MX Player's HW Decoder (not HW+) should be able to replicate the behaviour of stock one as it's based on mediaplayer api. If it doesn't work with MX's HW & works on stockplayer, we really need to check whether the issue is on our side or nit. samsung may not be using mediaplayer api or dynamically adjust the brightness values externally based on the metadata.
We do not have a S8 device to test. It will be better if you can provide some information like what are the videos (may be some links) working & what doesn't. It might be helpful to understand the issue better.

720 and 1080 10bit HDR files? no such things exist
also how do you know you're playing HDR? do you have a reference HDR capable TV? does the phone boost brightness and contrast automatically when you play them (not to be confused with Video Enhancer)?

720p wasn't HDR. 1080p was a sample of a movie in HDR(atleast the guy i got it from said so). And it looked to have high contrast/brightness. Not Sure if it was HDR or just looked like it. I dont have HDR TV.
If u got a small size sample of HDR 1080p or 4k 10bit HEVC video, please provide me a download link and i will report back to you.

The format of that video seems to be mp4, not mkv. Is it really x265 instead of x264?

yes, it's HEVC Main10.
Guy There's plenty of HDR videos on demo-uhd3d.com, h264, h265, 2k, 4k, 8 or 10 bits, 30fps, 60 fps, etc...
For info 4k HDR 10 bits videos read on TAB S3 with MX Player or native Samsung player have very high contrast, plenty of details and vivid colors.
Mxplayer
Stock player
Played the jazz video on Both players, looked same and it looked to have more brightness then the other non-HDR videos, but not enough like the other 1080p hdr video i played before. Colors looked great too. Played in crop mode on stock and 100% on mx.
Im unable to upload all the screenshots due to my slow net.

Video stabilization after updates

I remember video stabilization not working on 4K video recording, but a few updates ago it was fixed. However, after that update 1080p video stabilization stopped working. So now 720p and 4k videos are stabilized but 1080p are not.
Anyone has this problem? 4k videos usually take too much space, but I prefer 1080p over 720p..
Working well for me but I'm on Global BETA MIUI 10 8.8.2

When you are playing HDR video, drag the notification bar down and you can see that the grey color is lighter than usual.
But 4K 60 fps is not playing smoothly as it used to in Nougat. Hope Sony fixes it in Pie!

And thanks a lot BTW.But one question still. It Confuses me why it does not change the brightness while playing hdr like youtube does(YouTube hdr is just horrible)
If u try to play a hdr 4k video with MX Player Pro (idk if in the normal version hdr works) it will work well and smooth

Yeah I have mx player pro and it supports some audio codec which is not supported by the default player.All the 4k hevc 60fps demos are working fine with both mx and default player.Only youtube sucks

laggy playback on youtube on HDR videos

first of all, why is it very laggy now, playing HDR videos on youtube?
plus why if im watching HDR there is no more than 1080p option? my phone is 4k HDR why doesnt it give me such options?
but my most important issue here is the first one, why is it laggy like that?
I don't see any lag on YouTube. Maybe you have stamina turn on??

I don't have any probleme in 1080, 1440 p hdr 60 fps. Only in 4k hdr but I have a lower connexion.
Ps: I don't use youtube app, only in chrome or firefox in Web mode. Firefox is better, nothing lag
I have very small lag too, but only with hdr youtube video
I tried time ago to put on the phone some 4k hdr videos and they were smooth without any lag
So i think it's a youtube problem
I remeber 4K HDR on My Devices worked just smooth and without Problems but it started lagging one day without any Reason and YouTube just blocked 4K HDR on Android Devices. Very sad about that since i know that it can Work...
