[Q] Video on Note

Hello all ,
I've got a Note for a week now and altough it's an amoled screen , i've tried every kind of video from avi to mkv ( 720 p quality ) and even reencoded files to mp4 or h264. But black aren't deep black and more dark grey , sometimes even pixelated ( blocks ). I even got the impression that this was also sometimes the case with some games ( for instance the opening sequence in Asphalt 6 HD ).
Is this normal with Samsung devices and is there a way to improve this.
Thanks

SEE?
Gnote has same specs as the galaxy s2!
just 200 more hz on CPU.
Should play all those files man!
if no worky on note byt works on SGS2 then u have somekinda fail version manufacture thing!
try getting it replaced if it does not play avi or any files!!
it really should work! try some file on sgs2 if its ok there then u phone deff a bad batch!
get it replaced! u have good Reasons to get it fixed?
helped?

He didn't say anything about the files not running, he mentioned a complaint about graphics performance due to non-AMOLED-style deep blacks.
Ffs...

Thanks
Hello ,
I probably didn't express myself completly correctly.
The Note can play al those video file and even mkv without any lag , the problem consist in the fact that the blacks in the video are not realy black but more greish , like if the contrast was not calibrated right.I even got blocks in the black part of the video.I don't have that problem with photos.
It's also like there is oversaturation , i have tried the stock video player , act video and mx player , all give me the same result.

It looks to me like its video quality issue. If you run video provided by samsung "lightness & slimmess", you can check whether black colour is properly displayed (skip to 0:55 for the best result).

Thanks
I have done what you said and the black of this video are completely black.
This is a 1080p hd video.Does that mean that only hd videos work propely, I hope not.
The video with the problems could be played flawless on my Htc Sensation or on my Asus Eee pad transformer both with a slower processor.

Sounds like the OP's video bitrates are too low, since he is describing black crush. Higher bitrate videos do not exhibit those problems.

Thanks
This is propably the reason , but what do you mean by "OP's" .
Thanks

Here endeth the lesson!

Mine does this too. the samsung video plays fine but most other blacks are purplish and blocky. This happened in the green lantern film downloaded from the market, the first part of it is very dark and was unwatchable. It happens to a lesser extent in 1080p trailers downloaded from the net. When I use a black screen for my lockscreen it is the same. Even the starry background during the orbiting planet part in quadrant benchmark is a blocky purple mess. It is not even constant. Occasionally it seems OK. I am going to send mine back.

If the Samsung video plays fine, and other videos play fine, like MKV's in Diceplayer then it must be the videos you are looking at.
Good luck finding a device that plays back crap videos in perfect quality.
If you do find a device that makes these videos look good, I would question the bit depth of that device.

What is the point in getting a device with a HD screen and watching videos in sd or HD with low bitrate? It's like trying to watch VHS videos on a LED.. yes it will be pixelated. I suggest watching higher quality videos. Either MKV or xH264 mp4 with larger file size and bitrates of at least over 3mbps.

I think this whole issue can be explained by the technology in place here.
Super AMOLED does not light up black pixels at all, so when slightly gray/dark gray colors appear in the black, they tend to stand out much more than they do on different screen technologies.
Solution: higher bitrate videos, and/or deal with it

i have been doing some testing and i know exactly what the op is talking about as I'm suffering the same issue. i have a galaxy s2 and the note side by side, with the same video and the s2 renders correctly but the note is blocky and not rendered right.
I'll post a side by side photo when i get home tonight, but there is definitely a problem.even using high bitrate videos. i tried to even the playing field eg set brightness to max, adjusting the colour to normal, warm or even cool but it does NOT render correctly. it almost looks like the old days of 16 bit vs 32 bit colour on a pc. side by side with my s2 and s1 it is very obvious.

YUP. Am observing this too.
The initial Galaxy S (first) had a pentile matrix screen too so it would be useful to compare a video exhibiting the blockiness on a Galaxy S side by side with the Note.
It definitely does seem like it is rendering at 16bit, sometimes even 8bit.
Also I have observed this in the general OS too i.e Icons, pictures etc...
Am note sure what to think...
I am wondering whether Sammy reduced the bit depth throughout the OS to keep the frame rate as high as possible due to the higher resolution of the screen...?

Oh wait - you tested the Galaxy s1 as well which has a pentile matrix AMOLED and your test video rendered correctly???

yeah the s1 renders correctly. i tried do a screen capture of the video on my phone but it didn't seem that you can't do a screen capture of video running i tried the default video player, mobo player and mx player. none render correctly nor can do screen capture of the video still

I'm curious to know what he means by 'rendered correctly' on the S1. I think its more likely that the S1 resolution just isn't good enough to expose the weaknesses in the video encoding - the Note has nearly three times as many pixels as the S1 and the screen size is considerably larger so the 'faults' being described here are IMO the screen being good enough to expose weak video. Like someone mentioned earlier, it like watching an SD video in a lossy format on an SDTV and then an HDTV...

You are describing video with "bad" gamma. It is not the screen or the device it is your source material.
The "blocks" you see are compression artifacts. Most video you will get that is compressed will have this effect. If the demo video doesn't show these artifacts then it can't be the device. That of course doesn't rule out a dodgy video player app included with the device. Maybe that is sub par and has crappy coding of the codecs and makes bad video worse?
The reason you see them better on the note is because OLED screens will show shadow detail very well. A few stages above pure black will show up. Videos these days are calibrated, made and tweaked to look good on an LCD as it is the dominant tech and that is what the video makers are looking at while they adjust their settings. This means that colors and black levels adjusted to look good on an LCD may look like crap on an OLED.
On LCDs the backlight haze will often wash out these shadow details and crush the blacks so you won't see these artifacts as much.
You problem is that your screen is TOO good!
There lies a fault with the video player. There should be a gamma adjustment to be able to pull these "grays" closer to black.

what i mean is, i have the note, s2 and a s1.
lined up side by side playing the same video, the note's video in some parts is grainy, blocky, pixelated, the colors not correct compared to the s1, s2.
and this is with screen brightness set on max on all phones, display all set to standard, using the default samsung video player. but it makes not difference if you use moboplayer, mx player it is still bad.
like i said i'll post a picture when i get home later. i'm hoping it is a fixable with a software upgrade as i watch a lot of shows on my phone and so far i'm not impressed with what i'm seeing. even using 4gig 720p videos.
i've checked the video on my monitor and the video is perfect so it is just not getting rendered correctly on screen.
i hooked up the note using my s2 samsung mhl cable and in the lounge the video on the 55in 1080p tv is obviously inferior to the s2

Screen refresh rate

Hey guys, first time poster here.
Got my P20 pro about 5 days ago and one major thing I'm noticing is I can't look at the phone for too long because it really starts to hurt my eyes
I was wondering it might be tied to the refresh rate. Does anyone know what it is for the phone?
Logging into youtube to watch a video at 1080p does not state '60fps' on this phone, but does on others.
Does this phone have a sub-60hz display?

I get the option on my P20 pro for 1080p 60fps

1080p 60fps

Mine does say 1080p 60fps, the refresh rate on this phone is 60hz, thats weird. did you updated your phone, if not what firmware version you have. i never experienced something similar.

Yep it's on the latest version

Which version is your firmware?

App version is 13.32.52

No, i mean your android Firmware, Mine is 8.1.0.131 , Go to Settings>System>About phone > Build number.

Yeah I mentioned above, 130 firmware

It's not the refresh rate of the screen. It's probably because you have such a wallpaper that in the lowest brightness setting emits an uncomfortable blue light radiation. The refresh of the screen is just fine. As for YouTube, it supports 60fps if the source video provides it. I've noticed the same thing in the watercolour theme when the brightness settings where in the lowest point inside a very dark room. Apart from that situation, my screen is super confi in every light situations. (and when i changed me theme for a darker one, even that problem was solved)

Ahh I see. What a weird behaviour.
It's worth noting though that it's uncomfortable to look at on all brightness levels and with the use of eye comfort mode.
I'm starting to think it's just my eyes.
But on my many other devices I don't get the same problem

If your internet is kinda slow, youtube could remove the 60fps option for you.v

For me, I only noticed the irritating wave length emission only at the lowest brightness setting in watercolour wallpaper. It may have something to do with the specific colour and the lowest possible brightness setting. I must note, that it has a very low brightness setting as a phone. That's a good thing at night. My oneplus didn't go as dark as p20.

Ever since I got my phone it was able to playback 60fps YouTube videos. My firmware is currently (.130) Keep in mind it was still able to playback 60fps videos with older firmware.

You can always try going to www.testufo.com and see what refresh rate is this playing in the test.
With my Razer it shows as 120Hz but you should see 60Hz showing up.
With my Asus tablet P01MA it shows up as 30Hz.

Of course it's 60hz

This exact same thing happened to me with my Mate 10 Pro. It really hurts my eyes in such a bad way that I have blurry vision after looking at it, and some weird head aches. There is something wrong with these phones. I just ordered the Mate 20 pro but I think I will send it back. This needs more investigation.

Youtube videos.

I am using this phone for four days model cor l29 updated to latest version, and screen quality is just ok i have set it to FHD but only while playing youtube videos, videos look much softer even on 720p and 1080p they dont look sharp. Persons face look even softer just like beauty mode does on camera and on 480p videos look blurry. I used htc 10 before i always watched videos on 480p they were perfevt. Is this some kind of setting or due to the fact that it has 6.3 inch screen and only 409ppi because htc 10 had qhd screen and 500+ppi. Thanks in advance.

Is this FAKE, or is this a real night video from the p20 pro?

Hi Guys! Im looking for a phone that is the best in low light video (not photo!!!)
had an s9 on me a few days ago but the videos were way too dark in the situation i need it for.
now i found this video on youtube, can this be legit, or some gimmick used here?
Huawei P20 Pro - moving in low light : Bucharest at night 4K
the dark places (park, under trees etc) look way better than the s9.
but its hard to believe, i read in lot of reviews that the videos on the p20 pro are mediocre, not as great as the photo quality.
i suspect this was made with DSLR, not this phone....
any opinions? thx?

It might be real...I own one and the video quality is way better since android 9...I will make a video tonight and upload it on youtube and post it here...and let you decide. The light in that video is not bad,because of the street lights,so not so hard to be at that quality. But I always make videos ad 1080 60 fps,it's better in my opinion and stabilization is active.
But I will do it at 4k in a few hours(they obviously put the phone on a stand or something,the video had no shake at all,I will do it by hand,so a little shake will be in my video,the stabilization is only active at most 1080 60 fps)

Please note that the p20 pro does not have image stabilization in 4k. They used a gimball. That is indeed p20 pro, I recognise the wavyness of the video when panning around. However... The video quality is not good. Samsung is better at that.

hey thanks but if not a problem for you, plz make a video in the lowest possible framerate/resolution.
allow me to be more precise. im looking for the phone i can make a usable video in the lowest possible light.
i live in a problematic neighborhood, and if there is some argument that i record for evidence, i need video that is not just a black screen...
i dont need 4k for that, in fact even 480p would be enough if it has best low light sensitivity.
i try to attach 2 examples . THESE WERE MADE WITH S9!!! not p20 pro
1. part of my room with a 15W lava lamp. as you can see, apart from the lamp, everything else in unrecognizable (guitar on the wall, computer desk) you can barely see something is there.
2. garden+street with average suburban lighting. at the end of the video, there is good lighting, but if something is shadowed from the streetlight (tree, bushes) you basically see nothing, just pitch black. you woulnd even see if a person is there or not.
i converted to gif for better uploading but on the original videos the light level was the same, you cannot see nothing in the dark parts.
thats why it was hard to believe in the first post video, you can basically see everything, even in the shadows.

guys it wont properly play the above gifs, and many times just hangs. XDA site problem or its on my side...? thx

I do a ton of recording at EDM shows, rapidly changing lights, lazers, etc, and I've been beyond impressed by the video quality. The details this camera catches is nothing shy of amazing. I also don't bother with 4k, because in all honesty, I won't be viewing the videos on a TV large enough to take advantage of the resolution. So for me 1080P is more than adequate. Plus the steady shot/stabilization is definitely needed at my shows. My only complaint about videos on the P20 is the volume in loud environments. Ideally I should be using a usb-C microphone, but it's just easier without.

Ok,I will. I did not have time yesterday. I will make a video in my room,with light only from pc,and another with the monitor turned off,I have lots of leds so there is some light,but very low.

Here you go,I made a video in my room,the only light source being my pc: https://youtu.be/Hb5nxI_APNA

just 1 more thing. if you turn off the monitor, but put the video in 720p/30 fps, does the camera "see" anything?

There is no stabilization at 1080p 60 fps. You will only have it up to 30 fps.

Of course not,only the leds from pc,but in picture,night mode it can capture a lot more detail than I can see with my eyes.
And the video you saw captured very well,I did not see much more than the camera,it was very dark in the room.

thx, sorry, i was looking into other phones thats why it took long to get back...
i understand your reply, thats exactly my problem. im pretty much convinced that the original video is fake or cannot be made with a stock p20p camera app...
i live in a similar city like Bucharest where the video is made, eastern europe also.
in a business disctrict maybe, but in parks, normal streets etc we just dont have enough light for that
if you check the video you see that everything is visible even in the shadows, for example someone couldnt hide there cos the camera would see him.
thats just not realistic. i watched your footage, and is very similar to s9, although i had less light, but not complete darkness, sort of in between.
yes i know the night photo is great but i couldt find any evidence that it has better low light video then other phones... (apart from that one in the post)
i mean if its that good, how come we dont have a lot of amateur videos, or vlogger videos made at night with the p20p..?
just doesnt add up for me.
ps: i checked, my light was about 1/3 of your white PC screen.

I did not compare it with other premium NEW phones,but it's good enough for me,if I ever want to make a video at night,most probably it will be inside a house,a pub,or even outside is good enough with street lights...if you need more,I don't know what to recommend to you,I did not research enough. But I do know it's better than cheaper phones for sure...and better than my old P9 and my Asus Zenfone 3(which were both premium when they were released).

Redmi Note 9 Video Over sharpness.

Hi, so I've noticed something weird when watching videos on whatever video app I can use. i.e. YouTube at 480 or less (happens in all resolutions but it's more noticeable at 720 or less) it's very sad looking at very sharp videos because the 1080p screen isn't that bad.
I've searched for this issue but people say they have this but on RN8 Pro, so I think it's mostly MediaTek issue and I hope it can be fixed, my old Galaxy J6 had a better screen even though it was 720p.
