Youtube quality not HD

I noticed on an ipod touch 4, that the quality was HD.
I wonder why the the quality on the Android devices play in HQ.
Side by side, makes me cry to see what I am lacking.
Just odd Google's major product plays better on a non-Google device.

I haven't used YoutTube App much BUT is there a point of playing it at higher quality?
480p = 640 x 480
480p = 704 x 480
our screens = 800 x 480
The benefit we get from 720p -> 480p is fairly minimum as you can see :/

Kinda making this up, but it might be because of the higher resolution display that the iphone and itouch have.

yea the iphone 4 and ipod touch 4 does have a higher resolution

But when you're watching on a 4" screen does it really matter? Not trying to watch a movie off Youtube after all.

que? are those resolutions the old crappy TV lines that werent really even 480i?
480p= 720x480
720p ( i assume you meant) = 1280x720
So if our phones are 800x480, 480p would be a better image than a scaled 720p, I seriously doubt our phones have the scalers of most modern TVs or Monitors. Native resolution is pretty much always better. (the widescreen images being letterboxed 480p like out of a dvd player).
Yeah they have amazing, almost unnecessary resolution for a 3.5" screen. Great for text readability, but so is SAMOLED
So anyways, if a 960x640 (apple) device is actually defaulting to scaling 720p down, theyre actually shooting themselves in the foot... unless their scaler is a faroudja... but with iOS its all about status, so having that little indicator on the screen say HD, even though the device falls a bit short of actually delivering, and degrading the image by scaling when it is not necessary on such a small device (any phone), it just makes us look better . Wow, im used to having these discussions relating to CRT projectors, not phones So yeah, stick to native resolution or smaller.
That said, if our TV out option worked, then 720p or whatever the best output is would be a good default, if that option were plugged in.

Regardless of the quality the iphone degrades, it still looks better...that's what he meant lol so if it looks better with a scaled down 720p, imagine regular 720p

I am not talking about the resolution of the screen. I realize the iphone/ipod have higher res than our phones, and that relates to the sharpness. But I am talking about the actual content quality is actually much higher definition, as it takes longer to buffer because of this aswell. I know the Android app is better overall vs IOS version.
I watch alot of HD [HQ on our phones] of car videos and such, and yes it bothers me that it is not the best it can.
Not anything worth whining about Would be cool if we had [3g/mobile] [HQ] and [HD] options.
This is XDA, maybe we can hack it lol
*Thanks for all the replies by the way

Duh, been too long since I dealt with SD... you are correct.
But as far as 'looks good', its subjective, and looking at my friends touch, I really dont think video is even close... text is awesome... but theres too many factors, such as were you using youtube apps, or the actual site? Really though, I guess it boils down that you really prefer resolution over color, clarity, etc of the samoleds.... But everyone has their preference, I still prefer my Barco 808s projector running 720p CRT at 120" over most 1080p TVs... But to be fair most TVs are crap...

Yeah I noticed that too,compared even to my old iphone 3gs I just watch youtube videos using Dolphin Hd browser with AdobeAir flash installed,quality is definetly better than on YouTube app.

What I'm more concerned with now is actually watching a youtube video and not watching 3 seconds of it, it skipping, and then having to start over because it fails to load completely

The old youtube app was horrible and would always do that but the new one has been awesome so far.

Yea that's true, the new is way better for reliability lol

download a program called tubemate from the market. its free.
when you use this app, you browse it just like you would youtube , but when you watch a video you have 2 options. watch or download. when you watch it steams in poor quality, however if you download you can play it back in HD. its pretty cool. you can even download 720p ( on 4g its pretty quick)

1080p recording is zoomed :/

i read about the iphone doing the same but i have no clue

ya read that too on gsmarena.. hope they fix it by release time.

It isn't a really terrible issue,but i can't help but keep wondering what's the reason for that zoom.
It wasn't solved on iphone 4 so i guess there's a "deep and technical" reason beyond that.

Maybe the 1080p doesn't divide well into the 8 megapixel camera for easy conversion, so they make the viewable area slightly smaller so it is a nice multiple of the 1080p, because the processor can't handle the load otherwise. Shot in the dark.

Could it be that you can't display a full 1920x1080 video in a 800x480 screen?

i doubt it because you cannot display full 720p either ie 1280x720 but it doesnt crop/zoom that image when you video record..

How should a 800 x 480 pixel screen show full resolution of 1080 p ? It is not possible physically. Only via HML on the TV-screen You will have full HD res.

1) Scale 1280x720 to 800x480, in which case you get an aspect ratio error of 1% which is more than acceptable.
2) Scale 1280x720 to 800x450 and pad the rest with black bars.
Is that what was asked?

For comparison purposes, my Captivate does this also. 720x480 is zoomed; 1280x720 is zoomed further.

450 because it will be the same AR. Anyway, apologies. I should have read further back to see what the actual problem behind the discussion was.

Do we know the reason for this? All of the retail units are doing it.

Its simply a lower viewing angle at higher resolutions, its not that uncommon on video recording devices.

not sure I understand?
The youtube video in the OP shows RECORDING, not playback, right?
When it records in 1080p, the screen shows a zoomed in picture.
This is because the phone cannot take raw 1920x1080 video stream from the camera, and at the same time be encoding it as 1080p and saving it to memory, and downscaling that raw 1920x1080 stream to 800x480 to display on screen. This phone is powerful, but not that powerful. Or maybe that youtube video was of not final software.

Yes it's zoomed, and that's a hack to make it possible to record 1080p.
They've basically just cut off the pixels on the side, and are using 1920x1080 pixels from the centre of the camera's sensor.
This way, it doesn't have to process the "extra" pixels on the side, do pixel binning etc. The sensor is decent enough that 1080p still looks crisp at native res.

Best 1080p video to show off screen on SGS2

I was just thinking now that the phone should be hitting people's hands soon, it would be good to discuss the best 1080p video to have on the phone when you get the inevitable question from others such as what is the screen like? Or How is it playing movies?
Does anyone have links to stunning videos that we can download and use?

lol, looking at youtube "not" HD movies to see if the HD movie on the phone looks ok

This is a very bad example, to trully show the screen quality the videos should be converted at the max resolution of the screen.
Puting bigger resolution videos than the max native screen res will result in pixelation, because the phone then has to convert the video in realtime which is a much worse conversion than first doing it with a decent software and then displaying it on the screen without need for picture rescaling.

not to be a **** but isn't 480i standard resolution and 480p the first step towards hd? again could be completely daft but that's my understanding.
like i = interleaved, p = progressive
thus
p > i ?

I would call 480i an interface, not a resolution.
Most standard DVDs (and all modern standard DVDs) have video on them with 480 lines of resolution (480p). Some earlier DVD players (like from 10-15 years ago) could only send that 480 lines of data to TV interleaved (240 lines one frame, 240 next frame). All modern DVDs connected with component or HDMI send the unaltered 480p to the TV.
In phones, you use progressive by design (every frame is shown as full 480 lines of picture)
When you take a 1080p bluray and send that 1080p video to phone straight away, your phone will downconvert 1080p to 480p to show on a 480x800 screen. That downconversion process will produce WORSE resulting picture than a studio-cut original 480p standard DVD.

alright that's just how I understood it... that and an xbox 360 running on my old 32 inch tube tv won't give me a resolution higher then 480i lol
Edit: another question though... does 480 lines necessarily mean it's 480p? I though it also had something to do with the post processing done on the monitor as well?

If your TV is capable of physically addressing 480 lines on the screen, it DOES have resolution of 480. However if the circuitry can only produce those 480 lines in two passes by 240 lines, each pass showing every other line, then you are seeing 480i picture.
CRT TVs where a ray is used to quickly draw every single line, and that ray is not quick enough to draw 480 lines for every single frame, it would use 480i to show half frame each time.
480 lines for each frame are stored on your DVD. If you connect DVD player to TV with a composite cable you can only pass 480i signal. Same if your TV can only accept composite, or produce interlaced picture.for any reasons (see CRT example above).
With phones, you are not passing signal over any cables, and LCD/oled screens have enough power in the hardware to show all 480 lines at each frame. So you always use P in phones for videos.

True but i would like to add that 480i not a simple limitation of CRT, there are hundreds of CRT out there who display resolution of 2048x1536.
The main problem was the bandwidth of the cables themselves and not by the CRT technology.
The 480i is indeed long gone, it was used when analog signals were simply not prepared to output such a high definition, therefor to overcome that situation, tvs were made with an interlaced technology, basically displaying the same frame twice on different vlines of the screen, giving you the illusion that the image was beying displayed at a bigger resolution, even though it wasnt.
So he is correct when he says 480p as a more standard resolution than 480i, especially since we live in 2011 now and Interlaced imo is not really a true resolution.
Think of 1280*720p vs 1920*1080i, alot of ppl would prefer 1280*720p over the interlaced especially since lcds cant handle interlaced outputs as good as crts can.

i dont know how we made you feel dumb, youve asked a question, weve answeared it unbiased, with facts, thats all.

[Q]

I was wondering if there was some sort of video upscaling present when videos of a lower resolution like 720p and 1080p videos are played. I mean, there's not much point in a QHD screen if even 1080p videos are pixelated, right?

What do you mean? They have to be upscaled, how else would you want to watch them? In a small window? 720p should upscale without any quality loss (1 pixel becomes 4 pixels), 1080p should look great too but with a slight, probably not noticable at such small screen size quality loss.

1080p videos look great on my Tab S 8.4 i don't see any reason why they wouldn't on the Note 4.

Sorry. Yeah, I mean lossless upscaling.

inadequate said:

Lossless...?
Relative to the 1080p, sure, it's lossless as you don't lose any resolution from 1080p. Relative to 1440p? Well, in that case of course you lose resolution if the source video isn't 1440p.
Sorry, I'm not too sure what you mean by lossless.

Looks like I've been doing a shoddy job of explaining myself. Sorry about that.
I know that this may sound completely retarded, but what I meant to ask was this : Does the Note 4 have the same type of upscaling that is present in 4K televisions?

$ Bounty $ for native 2K and 4K

I'm creating a bounty for enabling native 2K or preferably 4K.
The resolution/dpi emulation still does nothing more than resize the xxhdpi resources (not even the xxxhdpi), so it still isn't as good quality as 2K displays on other phones.
Moreover, VR (the only real purpose for a 4K phone) is terrible. True, the screen door effect is gone, but at the cost of blurry less defined images same as a 1080p phone. Only Youtube and finally Netflix are able to use the 4K but other apps and games are unable to use the higher 2K resources and downloaded VR movies are fuzzy. Completely disappointing compared to my 2K phone. Also, with the emulated 2K or 4K, Daydream becomes tiny in the bottom center of the screen.
I believe the kernel controls the screen properties, but not sure if there was something to do with it in the ROM for this phone. While I'm sure I could figure it out with all of the easy handy guides, I don't really have time to do the research on how to do it myself. So, I'm creating this bounty.
I'll start with committing $50 to the person who releases the first stable one, but still donate to a second placer
If anyone else would like to sweeten this pot please post how much you would contribute.

I think it's a problem of native 4k apps, not the phone.
You can put it in 2,4k using adb commands, search here https://forum.xda-developers.com/xz-premium/themes/mod-change-default-resolution-to-4k-root-t3618843, but you need apps for that. I have Bobo VR Z5 and it's working perfect in 4k and in 1080p, but only without screen protector.

The adb command is just emulating 4K with the lower resolution resources as said in my top post.
This is how Daydream looks in emulated 4K https://drive.google.com/open?id=1i531VadSbzzu1Or1CMMvBYez5VFi_Mkp
I'm sure without the screen door effect you may feel you're getting 4K VR, but it actually 1080p.
For example, I take 4K 360° photos. the text on distant signs is readable on my 2K phone, but not on this XZP.

Awesome! Hoping this will attract devs to look into this.

It's pretty sharp. It's better in emulated 2k/4k, but good enough for 1080p. At least for me.
Also just to add, I noticed that if you use GMD Gesture Control and calibrate the screen, you'll see that the app reads the screen as 4k. (Even when on stock wm size)

$50 is laughable
get 10 guys together, $500 would probably interest someone

That's the point of this bounty. I asked people if the wanted to sweeten the pot and how much they'd be willing to contribute.
How much are you in for?

That app probably reads the pixel size rather than the set resolution. AIDA64 also reads as 4K the first time, but later shows 1080x1920 or whatever emulated size you set.
When doing the Daydream fix, it also changes the screen from LCD to AMOLED.

true that but even when on emulated 4k you get just as good display as 1080p, its still even not as crisp as other 1080p but cant tell difference, still with emulated 4k just to look at "enhanced" 1080p sucks!
plus you lose more battery than native 2k phones! i bought the phone because of its screen and I cant enjoy 4k at all times, or at least in the UI or any other app that I want in 4k....
im disappointed i really wish there is a fix to get native 4k...
I AM willing to throw in a 50$ as well if some one fixed this (as long as there is a root with TA backup (just in case the fix needs root to modify the kernel- I dont wanna lose DRM functions)

Excellent, and totally agree!
Now the bounty is up to $100.
Let's get more people. We can't be the only ones disappointed that Sony sold us a 4K phone *only in 2-3 apps that is actually locked at 1080p.

Could it be possible to just make other apps 4k by heavily editing them? Like the VR apps. If doing it system wide is too difficult then maybe editing apps might be easier.
I'm curious anyway, who can actually tell the difference between 1080p and 4k on this phone? You say 1080p looks better on other phones, so does the 4k look just as sharp as that 1080p? Also, how do we know Sony isn't just using the emulated 4k when it gets enabled? Not every photo in the album is 4k so how would it enable?
I did take a 1080p photo and a 4k photo and noticed a difference but I wasn't convinced. It didn't seem like a huge difference like it does against a TV/monitor at 4k. Especially on YouTube I cannot see the difference majorly when going from 1080p to 4k but can others? If 4k is difficult to make happen then maybe we could push 120hz at 1080p since it was said that the X series of devices have 120hz displays it's just disabled for some reason. The page needs translating but it shows 1080p at 120hz as an option. This was mentioned in a previous thread but I don't think anyone was interested in it. I think that this has a higher chance since this image exists.
Thats my thoughts about 4k on this device anyway. I think at this point 120hz might be a better option but that's just my opinion. 4k is great but it's only limited at the moment.

here is the thing, true that its very hard to tell the difference between 1080p and 4k on such small screen, so I took screenshots of before and after 4k mod and placed them together on my 24 inch monitor side by side and still can barely tell the difference even on huge screen which proves that its not 4 times better quality so its really fake 4k!! only time i can realize the difference is when i zoom in on both pictures and see that some details are washed out and more "pixel" looking at 1080p while on 4k mod still manages to show more details but then again, such difference in sharpness and detail shouldnt be so hard to notice since on my monitor I can easilyyy tell a difference between 1080p and 4k gaming on my VSR (virtual supper resolution) even virtually on my screen modded 4k has a lot more difference that stock 1080p
while even modded 4k on this device can barely show a difference, so might as well change that in a native way I really cant wait for a fix
PS: running 1080p on 1080p screen looks better than running 1080p on 4K screen (if screens are same size) - proven.
so down scaling the 4K screen of this device to 1080 will make it look worse than other native 1080p screen which buggs me, the least they could have done is add an option like samsung did to just adjust the quality as you wish... I hope they add that in the next update

Yes I agree 1080p on a 4k screen does look worse. On most TVs it doesn't but on my Acer predator 28" 4k monitor it is very noticeable that 1080p looks like 720p when duplicating the screen next to my 1080p monitor. The desktop does look noticeably blurrier. However, 1080p content on the 4k monitor doesn't show a huge difference so I'm not sure what that's about only playing games and the desktop look bad at 1080p. Maybe the XZ1 could have been a better option but even still know that I have the second 4k mobile device on the planet and the only 4k HDR device is still cool. It's certified to be 4k so it can't possibly be a fake 4k it has to be really 4k else Sony would be lying and with all those TV experts I don't think it wouldn't be possible for them to do real 4k on a smartphone.

The screen using the emulated 4k is razor sharp. By far sharper than any other phone I've used including the note 8. Are you sure your not just mistaking the overly unrealistic saturation of a amoled screen compared to a LCD one? I dont mean that in a sarcastic way, i genuinely dont see any comparison between the two. I havnt used the phone for any VR stuff though so can't comment on that

you are right but im not comparing only with samsung, also with HTC and the previous version of xperia , the Z3
yes maybe on emulated 4k it has sharper screen but keep in mind that on 1080 is not as sharp as other 1080p, even on 2k it isnt only on 4k mode it is unbeatable which to add is emulated and not native
put phone on 2k battery dies so much faster than lets say samsung or HTC which both have same CPU GPU and almost same battery size, how is that? because the resolution is emulated, which forces GPU to resize source resolution of 1080p to make it in a fake way look like 4k instead of showing native 4k (which doesnt require such hard work from GPU as its showing real pixels instead of emulating fake pixels!) Which leads to less over heating and less battery consumption.
heck even on 1080p screen looks worse and still get worse battery life than other phones...
thats what bothers

not exactly but some other phones have better 1080p than the 1080p on this device, yes text and symbols maybe just as sharp its hard to tell but im talking about pictures (for example, in instagram, facebook. youtube thumbnails etc...) I once was on 4k mode and it was very hard to tell the difference between this phone and the Z3 and even some times the z3 showed more picture details in instagram and its only 1080p...
im not complaining about the screen though, its pretty decent and with 4k mod on it looks superb, im just saying sony has put some thing in a device that is useless and im trying to figure out why...
by useless i mean sony left us no option to use such settings, why dont they add the options of 1080-120hz or 4k? naive and not emulated! this bugs me
and yes it is 4k, just like youtube you dont have to watch on 4k settings, but you can see the option is there which means it supports it.
that means even if you dont have a 4k video in your video app or album app, the option is there that means if you ever have a 4k video on there the device will play it at its maximum resolution.
phones that dont support 4k will show that the video looks as sharp as 1080 instead of real 4k
