Poor quality or not, the artifacting he's talking about is not present during playback on the rezound. That means that it's not just a poor quality issue. If it was, it would be present on any screen type. But it plays perfectly and looks as good as the show would on TV.

I believe this has to do with the pentile screen and is not a codec issue. I had it on my Droid 3 which was also pentile. While it was not super amoled, it displayed the exact same issue the OP is talking about. There is nothing you can do about it. It's simply a limitation of the screen tech. It doesn't seem like it bothers most of the people here so its probably not nearly as bad as it was on my D3. But it obviously bothers the OP and it would probably bother me as well.

Thanks for all the responses. If this is just a codec/crappy video, I've been unlucky in what I've been trying. For the folks who HAVE tried this in a VERY dark room, can you do me a favor and post a link to or instructions to find the video? I do have a netflix account. Unfortunately, the wifi signal in my parents' house is crappy and they are in BFE so I barely have 3G haha. But once I can reproduce this in a dark room, I'd like to try a video that people have watched that does NOT demonstrate it.

If you can post the exact time in the video where there is a similar scene to the test video I posted, that'd help so I don't have to watch an entire movie or something

I think I saw a couple of mentions of HD video trailers, but was that on youtube or somewhere else? And where (time wise) in the videos should I check out?

Thanks in advance!

I wonder why some people can't see it then, even with my test video. The blocky artifacts I can sort of fix by boosting the contrast, but there are other cases where I see the "slicing" artifact. The best way I can describe it is that it looks like I'm seeing a partially transparent pinkish (or greenish, depending the background) horizontal bar graph overlaid on the video.

There is a HUGE library of very good high definition video trailers that are playable on the Nexus here:

Movie Download Index (0 - 9, A - H) | Movies - Digital Digest

I downloaded the Tron trailer recently, which has a lot of dark images to test. I haven't tested it yet in low light conditions.

I wish I could show people (but in a way, I don't know if I want to, because as they say what has been seen cannot be unseen). I truly think this is an issue with the combination of pentile+samoled. Maybe I just need to watch videos in bed with all the lights in my bedroom on.
I watched the clip you provided all the way through once, and to 20 seconds in a few more times, and I'm not seeing any problem. I'm in my office with the door closed and the lights off, but I went into the bathroom with no windows- pitch black, and no problem there either.

I wish that I could help you.

First of all, if you'd read the threads, I said this was just a sample clip I found that definitively demonstrates the issue. Maybe I should watch it though, since you have so much disdain for it.

As for obsessing, yes I admit I am. Wouldn't you if one of the top 3 things you do on your phone was a MAJOR step backwards from your 2 year old phone you used previously? No phone is perfect, but there are certain things people are unwilling to "live with". For many, it's a poor signal relative to other phones, but that's not a deal breaker for me. Poor video quality playback IS for me and may be for others, which is why I started the other thread.

Also, if you'd read the other thread you would know that this blockiness is sort of correctable but the other issue (I'll call it "semi-transparent bar graph overlay) is much more annoying to me. I still don't know what to make of that, and I have to find an example of it to post in the other thread.

But, you are right, two topics on almost the same subject (well, the other is more of a superset of this) doesn't make sense. So I'll ask the mods to close/lock this one and track the issue in the other thread.

I just don't get it. I really don't think it's that subtle in a dark room. Perhaps it's something to do with the brightness of the screen automatically going high or low or something? I'll try fooling with the brightness inside mx player, but I've tried mx player, the built in video player and one other one from the market I can't remember the name of.

*edit* Viewing in mx player and manually dropping the brightness does mask the effect a bit. I grabbed the MIB 3 HD trailer from youtube (via youtube-dl) and I could see the effect every so slightly on Will Smith around 24-28 seconds into the trailer. Definitely less pronounced, and also the video is 1080p so the size of the blocking was smaller.

I'll try some other video sources and see if I can find 720p dark content that doesn't have the issue.

By the way, which video player are you using and what brightness is your screen set to? Does your video app adjust the brightness when it starts? I'd like to try to watch it under IDENTICAL conditions as you did and see how much less noticeable the effect is. Thanks in advance!

I haven't directly seen the issue you are referring to, but also haven't truely investigated it thoroughly either. I'll try later.

I will say that not everyone's eyes are the same. Some people were extremely sensitive to color banding problems on DLP technology, while others couldn't see it. Some people are sensitive to refresh rates, and others have an easy time with 3D art while some can't see it no matter how many times they cross their eyes. Point is, not everyone sees the exact same way. So keep future posts with that thought in mind.

Good point, and you're absolutely right. What *I* see doesn't mean others see the same thing. Even if we were in the same room watching my phone in the same conditions. I'm just trying to compare apples and apples so I can determine if indeed I received a bad couple of phones.

I'm going to go watch the video again with full brightness and take a screen shot when the guys' head is exhibiting the artifacts to see if it still looks that way on the screen shot (which would indicate a codec/video quality issue I guess).

Just tried and it is still there in the screen shot. I think its a codec issue.

I honestly don't know why others can't see it. Perhaps they just aren't looking hard enough or maybe it's a condition that common to super amoled (in the sense that it affects most) but there are a few that it doesn't occur on). I honestly don;t think you got a bum screen. Like I said, I'm pretty sure it's a super amoled thing. Check out this post, which is about a similar problem with the super amoled screen on the razr that also only seems apparent in a dark room:

I took a screenshot during the problematic part after pausing it. While paused I could absolutely see the blue blocks. The screenshot does not depict the issue, but then again I'm viewing it on a laptop that has an LCD heh.

Here's the screen shot I took.

Really?? I took a screen shot and I don't see it in there. Weird.

Maybe I will try to find this episode online in avi format which I think usually contains "regular" mpeg 4 part 2 video not H.264 and see if it still has the issue. Worth a shot I guess.

It looks very much like we had two threads on the same issue, really - so they're now merged.

Hope this helps!

I just opened your screen shot on my phone. Its not as obvious but when I zoomed in I could completely still see it(blue squares in his hair).


EDIT: Nevermind I just opened the pic on my old thunderbolt and couldn't see the effect. Its definitely a GNex issue.

I think it's an s/amoled issue, not a GNex issue. Someone posted a link to a Razr thread of a ton of people complaining about the same thing. So I guess at this point I have to decide if I want to keep it or get a Rezound or wait for another device that has a non-amoled screen. :/

Found the avi of this same video and it's still there on that and even worse. I think the lower the resolution, the worse it'll appear since there are less pixels and they bleed together due to the lack of quality and pixels in the area.

You're not understanding that the black levels on an AMOLED, and I'm pretty damn sure a Plasma TV (I'll be testing tonight at dark) will not hide the crappy quality like LCDs that just turn blacks into a blob.

The artifacts exist in the video.

I watched the Godfather opening scene in shitty quality on Youtube and a couple of other videos that are very dark scenes (End of the Aviator) there isn't a similar effect but I can see compression artifacts that the blacks hide in an LCD.

Default Pictures of what I'm seeing

I took these in a completely dark room at various brightness levels in mx player (full brightness, level 2-3, and then level 1). Level 1 is one step above NO brightness, so about as low as you can go and still see the darn video lol.

Anyway, here are the pictures:

Full brightness:

low brightness:

Maybe it's just me, but I'd rather see a uniform area or blob than blue splotches jumping in and out. The blob looks WAY more real/less distracting. So people out there would rather view these artifacts instead of a uniform area? I guess at least for me I'm glad LCD hides this kind of stuff. And I guess it's pretty obvious my dinc was an SLCD screen, or I would have noticed this on there, right?

Crap. I just posted a thesis level post on this. And it must have dissappeared with the thread merge.

Quick take is this is 100% codec and AMOLED related. The reason you don't see this on traditional LCD displays is because the noise gets washed out by the lower contrast. When the contrast is so high, you can see artifacts caused by lossy codecs. On good transfers, artifacts are minimized.

Unfortunately, this really sucks then. Because the quality level of netflix shows this in almost every dark tv show/video I have tried.

Yessir.

Posterization is not caused by the display, nor is it typically caused by the playback mechanism... it's almost always a codec issue. The codec is actually creating these artifacts because of the compression.

Jack up the contrast on any compressed medium - highly compressed JPGs are a good example of this - and you'll see artifacts.

Well, I guess I just prefer a screen that hides these artifacts then. I realize this may be the norm for this screen technology and the encoding in use, but I prefer the look of an LCD screen where there may be some loss of clarity to seeing a bunch of bleeding/hosting artifacts. I just have to decide if this is enough to make me return it or not I guess.

Has anyone tried the earlier fix using a 3rd party app to adjust the default screen contrast/brightness? I tried it with mine and it pretty much eliminated this issue.

Boosting the contrast a little bit can alleviate the blue blocky artifacts. But then that makes the "ghosted bar graph" effect much worse. So I have to have one or the other.

I don't see any issues with the test video on my GNex. It would be pretty pointless for me to try to re-encode a bad file, so I'm curious if anyone has used my handbrake preset file (attached) from the other video thread.

I have a few 1080p mp4 videos on my GNex at 4000-5000kbps, and even the darkest scenes look great.

I don't see how this is possible. People are saying this is NORMAL for an amoled screen when there are dark regions and any artifacts. I'll ask again:

People who do NOT see this in the test video I posted, please do so in a COMPLETELY DARK ROOM. If there is any ambient light, you almost certainly won't see it. And I really want to know every aspect of your environment. What video player are you using? What brightness level is the phone set to and/or what brightness level is the player set to if it has its own brightness controls. Please provide as many details about your phone setup as possible. Perhaps you are using a player that masks it or have your phone configured so you can't see the problem. I'm more than willing to try out different settings/etc to see if it goes away or is masked. But I have not been able to get rid of the artifacts. Bumping contrast up slightly helps with the blue blocks, but NOT with the ghosted semi-transparent bar graph effect. I am grabbing a video to see if I can show what I mean by this.

I agree. The high quality trailers here all look great.

I think the important take-away from nj02vette's post is that high quality screens will reveal the side-effects of bad encoding. Ironically, you may not see this on low quality screens -- but, you will otherwise suffer from watching a lower quality screen in other regards.

If this is indeed a codec/compression issue, then it probably can be minimized with less compression and higher bit rates. However, if encoding at HD films and TV shows at bit rates of 5000-6000 is the only way to minimize the artifacts, that seems very inconvenient for anyone that encodes a lot of their own media. Aside from the time it would take, the file size for a standard film with a length of an hour and a half would be around 4gigs. I encode all my films in 720p with bit rates between 1500-2500, resulting in files sizes of just 1-2gigs. And they all look fantastic on my rezound.

I actually don't think my bitrate of 4000-5000kbps is necessary unless you plan to output to a larger screen regularly. I do think optimizing other settings can help greatly, like b-frames and motion estimation.

Bottom line, I don't see any video playback issues under my normal video-watching scenarios, which does not include watching things at maximum brightness in a dark room. 50% brightness on an airplane, sure. 70% in a well-lit room, no problem.

If I put my TV (52" Sony XBR9, which produces some of the deepest blacks ever on LCD) on max brightness in a dark room, the blacks would not look black at all.

Even ZERO level brightness in a dark room is unwatchable. Viewing in a very dark room at any brightness is a problem.

I went to the darkest room (essentially pitch black) room in my house, and I did not see any blue using the stock player and the display set at auto-brightness. However, I did see the artifacts in the guy's hair at the very beginning and middle of the video. The same artifacts weren't visible in his shirt at the same points in the video. This leads me to believe that it's an encoding issue.

I also played a file I encoded from original HD source, and the blacks were perfectly fine using the same device settings in the same room. I encoded that file using the handbrake settings I attached in my previous post.

I can see artifacts out the wazoo with auto brightness. I also see it in his shirt, too. I don't understand how this is not visible to people, I really don't.

On another note, all the videos I transferred over from my Droid X in 720p with no additional encoding do not exhibit an posterization (thanks BV for the correct term). And I have several in low light scenerios. This is the result of transcoding and becomes evident with the super contrast of AMOLED screens.

I posted earlier that even those with perfect vision can perceive things differently. So we should all refrain from going there.

FWIW, the SA+ display on my Droid Charge is perfectly black in these areas regardless of brightness and ambient lighting. The encoding is fine, and it's not an LCD vs OLED issue. It may not even be the codec. I think it has to do with the pentile arrangement and how the intermediate firmware handles interpolation of the true resolution to the physical resolution. It's probably something that could be adjusted in firmware. There's just no reason for an all black area like that to display blue blocks. The pixels should be off. Who would be responsible for investigating this issue? Samsung or Google? Probably needs to be reported.

I just watched 30 minutes of Pirates of the Caribbean: On Stranger Tides in HD on my phone and the large black areas were horrible with weird blueness to them. The smaller black areas appeared fine. I still think the issue is with software related. It still looks like a compression or codec issue to me.

I think whoever said it was just the normal compression effects/artifacts being amplified/exposed by the samoled+pentile screen hit the nail on the head. It's not going to get fixed on the nexus (or any s/amoled screen for that matter), at least with this generation of oled screens. So I, and anyone else hating the dark conditions/dark video playback, needs to decide for theirself whether it's something that they need to switch to a new device over. The verdict is still out for me. Honestly, if I thought I could go get a rezound to TRY for ONE NIGHT to compare, I would at least go give the rezound a shot. But I'm not paying $70 to do a double swap. Even if the video is flawless on the rezound (which I bet it is, since people have said the LCD screen will mask the artifacts/compression effects), I don't know if I can live with sense until ICS comes out, and even then HTC will probably bastardize ICS to the point of it being unrecognizable. And who know if/when the rezound will get s-off. If I knew for sure it would within a few months, I would probably just bite the bullet and go with it and then wait on CM9. Since that seems to be no guarantee (what happened to HTC playing nice with the bootloader?!?), I think I have no choice but to keep the nexus as long as possible and then if the video issues are still bugging the sh** out of me, re-evaluate my options on 1/14 or just live with it.

On a side note related to battery and the radio, people seem to be think an update to improve signal will improve battery life. I say quite the opposite. I imagine one of the biggest tools in improving signal quality is to bump the signal power. More power == more battery drain. So I'm almost afraid they will alleviate the signal issues to some extent, only to sacrifice battery life. Time will tell.

I randomly chose some movies/shows that looked as if they would have dark parts on netflix tonight in a dark room @ ~25-30% brightness, and I admit the artifacting that is huge in the sample video I posted wasn't nearly as prevalent. So I think the folks saying a lot of this has to do with video encoding quality are correct. Yes, I think the s/amoled screen makes it look "worse" (though some would argue having an area with NO definition/color separate is worse), but it's a classic case of "garbage in, garbage out". Hey, at least I have nearly a month to test drive this sucker and see if the video thing is truly an issue for everything I watch or if it was just a few things I noticed and coming from (a suspected SLCD) dinc, they were more obvious to me at first. I'm hopeful the signal issues will get straightened out, so as long as the video playback doesn't bug the sh** out of me 3 weeks from now, I think I will hold onto my nexus. Time will tell, though, as I watch more stuff. I will say that if it looks like utter crap when I watch the Dr. Who Christmas special, I may have to have my wife hold me back from returning it on 12/26 :P heheh

night folks.

I watched an HD trailer for Avatar on Youtube and it was FAR better than either the POTC: A Stranger Tide or the Vampire Diaries HD Clip. It wasn't perfect, but it was much, much better. This is the trailer I watched on my pc and then on my phone.

For the most part blacks are fine, but in my test clip, the guy's hair is definitely blue/block when you watch in a pitch black room. I don't see the blueness either in a room with ambient light. You have to be in a completely black room.

After finishing the rest of the POTC: On Stranger Tides movie, I must say that the blue blocks weren't really an issue for the most part. When you stop trying to look for flaws in the picture, you really start to enjoy the incredible image quality of everything else.

This is especially noticeable when the black isn't true black but a lighter shade of it that constantly changes due to slight changes in lighting (within the scene itself). It made certain movies just plain unwatchable on my d3.

It doesn't seem like it bothers most of the people here so its probably not nearly as bad as it was on my D3.
Not to be rude, but your Droid 3 is irrelevant here. It has an RGBW type of Pentile screen, which doesn't look anything like the Nexus' SAMOLED RGBG Pentile. They both can be said to look "worse" than standard RGB, but in very different ways.

No offense taken. Maybe I don't understand the whole pentile thing. But, then again, the most important thing is what I see. And I saw horrible artifacting on my D3 similar to what the OP was describing. Regardless, the key point I was trying to make is that there is none of this sort of distortion with the rezound's SLCD screen and that still applies.

Good points kishin14. My only complaints of the Rez screen are that it's about as useless in direct sunlight as my old OG Droid, and the viewing angles are poor off center. Otherwise videos look great and text is magnificent!

I must definitely have had the SLCD screen on my dinc then. No artifacts to speak of and it was worthless in full sunlight even at max brightness. The nexus screen is decent at like 25-30% even in bright light. Just wish there was a compromise between the two technologies so I could have my cake and eat it, too.
