Anyone hear if Samsung are fixing the video playback and camera quality?
The video is great in HD but when you watch lower quality rips the film looks great in day parts but at night in movies you can see lots of blocking, yes there should be some as lower quality but not at the level it shows, I tried on my i8910 and the sgsi9000 and the same video in night time scenes looks better on the i8900, I did hear that the reason the sgs has bad blocking is the firmware is not right, the phone is not reading the difference in the shades of black or something.
And camera, I hope this again is firmware as the pics are fine until you zoom, they are washed out and blocky, I know it took awhile before someone modded the i8910 to get the best jpeg code for it so fingers crossed Samsung or someone on here does that.......just seeing if any news on these two things.
Cheers

Emmm..? Great quality in both camera and video playback here...
its one of those things that when you see it you dont miss it again, I did come across a page on the net with a guy speaking about it, its a firmware thing, it will never be perfect as there will always be some blocking with lower bit rips but at this time the sgs shows it up more than it should, from what I remember the guy said it was to do with the graphic chip and it not reading the differences in blacks so rather than a blend with shadows and dark stuff (like a guy running around in a cave say) it shows blocking, anyway this guy said he did something so that it bypassed the chip and the picture was fine....but he did not say how and nor can I find the bloody page again.
Camera wise, well its an old story with Samsung, they shrink there files too much, dont know why and they did not learn from the error with the i8910, it took hyperx and faenil to sort the code out and get better quality pictures, from what I read on here its same problem.

I love the sgs and hope these things are fixed by them and I dont have to wait for some person with talent to fix it
Ideed, there are differences in quality. Never noticed them.
Well, I suppose it should be pretty easy to fix if anyone actually got to do it (I know they even did it on symbian, which is like the most complicated os ever).
For the quality of video - never really tried low quality files, so never noticed a thing. But from description - it could be something to do not with drivers or anything, but with screen itself (all the deal about true black, which we dont see on normal lcd display). But thats just guess.
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
Hey there,
I just bought a GT-N7000, and I am quite dissapointed with the display quality. I have a lot of experience with Super AMOLED (plus) screens from Galaxy S and SII, but I am facing an issue on my new Galaxy Note.
You can see it on dark pictures, photos or mainly videos. It looks like the screen on the Note were more sensitive of brighter tones of black then the screens on S or SII. Let's say I am watching a video. If the scene is full of light, everything is all right and you can definitely see the breathtaking quality of the Super AMOLED screen. But when the scene goes dark - everything got different. On the S or SII, all the dark led pixels were inactive, so the screen was absolutely black on dark places. But, it looks like my new Note is a lot more sensitive of light, and the result is, it finds a not-absolute-black places all over the screen, and the scene is not Black at all. There is around 50% of the screen's area which is not Black, but just dark grey, consiting of small squares. Also, these squares flicker in a very high frequency, which makes it even more annoying. This is also happening with photos taken in dark, but, of course, the squares are stable.
Are you facing this issue too or am I the only one? I hope you did understand my words, if not, I could provide some photo samples of what I'm talking of.
This is called black crush and present on all Note 1s to varying degrees. Samsung refused to acknowledge it as an issue.

Search for the thread in the n7000 forums with 'black clipping' in the title If you don't find it as black crusg. Lots of good reading there. You will find all the info you desire in this topic.

Hello everyone ,i recently got a z3+ and i noticed that the black levels of the screen are pretty bad...coming from an oled display i was expecting some diffrence but not that bad...I watched some movies and in the dark scenes it is very difficult to see the picture ,everything looks the same and you cant really see the characters or the background ..its a mess especially in daylight conditions its almost unviewable.Cranking the brightness all the way up helps a lot -again in very good lighting enviroments/outside/daylight i cant see a thing in dark scenes- but then the black levels are too bad almost grey not black..
I also had a z1 compact which i dont think it was that bad, i'll try to test them side by side...
So i was wondering if a have faulty screen or something but i would like to hear your experience ...
Overall its nice screen bright with nice colours etc..but the black levels are a dissapointment in movies/videos..
Also i have disabled all screen enchanments (x-reality etc) and my white calibration is 178/162/37 RGB
Based on this review i was expecting more...
Blacks are pretty good in my opinion contrast ratio is brilliant for a ips. But this may come from you're eyes trained to a OLED screen. It's like my TV I have a lg OLED in the living room but a led in the bedroom and now I'm seeing grey instead of black :silly:

Here are some photos of my screen's blacks ...taken at 100% brightness in a 100% dark room ,all screen enchanments off, showing the same black level block picture in all 4 photos...i tried to adjust the camera exposure to make it look as close as what i was seeing ...as you can see it actualy can lit the desk under it and there is massive light bleed (if thats the correct term) out of the 4 corners in low viewing angles ,it actually creates a shape of X of light in a surface...Thats all please try it too to check out your results so as to know if i have problematic screen...
So i have been noticing this since quite a lot of days. The p20 pro has black crush issue in videos. The screen tester apps dont show it because the problem is only while playimg videos. The black shadows are never really black. To test this you need to watch a video with complete blacks in 0% brightness in dark room. You will see that there are white dots in the black screen. Its so much irritating, hope huawei fixes it soon as it is most likely a software bug like on s9
As an example if you see at the very start of the video where the helmet falls, the screen should be completely black whereas on a close look you can actually see white dots all over screen
I can see it in your video, but it doesn't happen on my screen in the same situation.

So you mean the blacks are perfectly black for you on zero brighntess in a dark room while playing this video?
I can see the white dots on my p20 as well as on my pc... I think thats what the video should look like... Its like dirt falling at the same time as the helmet.

The background in this video is not completely black for me in the conditions i mentioned. It feels like the pixels do light up
Btw it must be some software bug because the borders which were not covered by video including the sides of notch are completely black

@mathab you cant compare with a pc. You need some other amoled display device because the pc will light up the pixels as well. Anyway also try the other video posted in next comment.
Edit: you can try this too
I thought where talking about the little white dots on the first video
In the last video you posted I can see backlight in every scene :/ just as you.
Dont have any amoled screen at hand to test (cause maybe the video does not have true blacks ¿?)

try this one, its very clear after 2-3 seconds that your eyes adjust to darkness that theres something weird going on, white spots are all over the screen.
FYI Ive got an L04 from Mexico rebranded to L29

Yes this is what i have been trying to say. And the weird thing is it only happens in video and not on sides of notch where the video doesnt play. So the issue is not with the screen but the huawei firmware. Hope they roll out a fix soon.
I personally believe there are many users with this problem but they havent noticed it.
I do see them to when the brightness is low! I notice that when you scroll on any page that got black content, a sort of purple shadow follow the black content. Anyone experience this?
