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.

I meant what I meant but I forgot one 720 x 480..there are multiple standards for 480p based on the sample such as4:3 (640x480)..

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)
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.

So the NExus 7 has a resolution of 1200x800, which is very close to the native 720p resolution size.
My question is, when streaming a 1080p video file on the nexus 7, will it look any better than a video size with a resolution of 1200x800 or 720p?
Wouldn't it be better to convert the resolution of 1080p videos to 1200x800 so reduce file size yet reduce absolutely no quality?
During this video http://www.youtube.com/watch?v=sOqn62m49S0#t=11m55s the guy plays a 720p file and 1080p file, they are streamed from a usb drive but how does the performance differ on the two even though they are playing on the nexus 7 screen, so are being outputted at 1200x800?
Another question I have is can I stream a 1080p video file using micro HDMI cable from the Nexus7 to a 1080p capable TV? Will the Nexus 7 GPU output 1080p on the TV full screen?
Help is very much appreciated!

The nexus 7 doesn't have a micro hdmi. So that's not gonna work. Only a mini USB but you can use an otg (on the go) cable to attach a flashdrive with movies you would like to watch. 1080P and 720P are compressed differently. 1080P is a much heavier format so if you really want the full 1080P experience your gonna have to stream the full size video which can be around 10gb. By reducing a 1080P video you can stream it easier and it will still be HD but quality will be less. 1080P is always going to look better than 720P because it is compressed so many times so the picture is literally made tighter increasing clarity. Lets say you took a 5mp picture and a 8mp picture and looked at them on the nexus 7 when you look closely at the pictures you can see the clarity difference between the 5 and 8 MP. Compression is what makes the biggest difference. You are cramming more and more information into a tiny place. So 1080P will look nicer on the nexus 7 but so will 720 but the details will be clearer on 1080P even though the nexus 7 outputs in a lesser resolution. But the difference will be harder to see on a smaller screen but much more noticeable in a bigger screen. But streaming a 1080P can be choppy because eventhough they are being displayed at the same resolution they are being input differently. Sorry for the long explanation

Ok so is it possible to make a 1080p file reduced in resolution but not as compressed? So it still includes the detail you are talking about?
I thought that the pixel resolution was the main quality aspect of a video being outputted.
For the micro usb, i meant a micro usb to hdmi cable you can buy? http://www.amazon.co.uk/Kitvision-Micro-HDMI-Adapter-Cable/dp/B005TF2F2W

Mhl is not currently supported on the nexus 7. So no micro USB to hdmi. 1080 P is the resolution so if your going to reduce that then it wouldn't be 1080P. It might be 1080 I which is less but 720 P and 1080 I equal out to the same resolution. Honestly 720P is going to give you plenty of clarity and I wouldn't stress about 1080 P. Unless you have 1080 P movies downloaded I wouldn't worry about it.

Zippox your making a mistake. You are confusing scaling and compression. Compression determines files size, clarity (less pixels). Scaling which is done by your set top box, DVD/blu-ray player, computer, smart phone, tablet just makes it fit to screen or what ever size it needs to be. Will 1080p look better on nexus then a 720p that's a yes/no answer. It will depend on how much each file was compressed. Generally a 1080p file is compressed much less then a 720p. Why? Cause its resolution is too huge. Which means compression (blocks aka pixels, seeing weird shadow/dark areas move, blurry images) can be easily seen if its not done right. If you set a 1080p file and 720p file and compress them the same bit rate as the 1080 and view it on a 7" native 720p screen you will not notice a difference. Why one will be scaled down and the other will not be scaled at all. Clarity will be equal at that point. Now once that 720p file has to scale up then its defects will be shown regardless of actual screen size. And trust me you will never stream a 10gb file. You can download a 10gb file but you will never stream that. Those stream sites actually offer two completely different files. The streaming file is much more compressed. Why server load, then actual internet speeds. That would have too much strain on the server. This is why streaming is not an alternative to actually owning the file. And the digital download is not as good as its blu-ray medium.
But scaling and compression are not the same. And you were getting them confused. There is no point in a 1080p file for the nexus 7. Unless you have it 1" from your face and straining your eyes you will not see the difference if its encoded (compressed) properly. 1080p scaled down to 1280x720 will look just how its supposed to at 1920x1080 you just need to be closer to the screen. But then make that fit on 7" and 720p scaled down. That's just waisting space on the nexus7. a 30 minute anime file at 720p is generally 250-350mb. Its 1080p counterpart is usually 700mb. And it will look the same on your tablet. The only difference will be based on source material. TV capture vs blu-ray rip.
Then there is compressors. H264 8bit, h264 10 bit, divx, xvid, wmv, mpeg2. This will also define how the video looks. H264 10bit is the current best compressor. You can have a h264 10bit compressed lower (in megabytes) then h264 8bit and it will look just as good as its higher filer size h264 8bit. But naturally they will compress it less to completely blow h264 8bit out the water.
None of this has anything to do with scaling. Scaling down you see less but still looks very clean, and clear. Scaling up makes for a sloppy mess. And lesser you compress the less of a mess it will look but it will not ever look as good as native or less. And scaling of actual screen you should never see a difference as long as resolution of screen isn't touch.
There are two meanings for scaling and 1 for compression. Scaling resolution, scaling actual TV. Compression is only for file size which determines the actual quality. Overly compress it will look horrible. There is no under compress. Scale up from files resolution will degrade any image.

N7's resolution is 1280*800 and you should use 720p video as 1080p would just be a waste of space.

But scaling and compression are not the same. And you were getting them confused. There is no point in a 1080p file for the nexus 7. Unless you have it 1" from your face and straining your eyes you will not see the difference if its encoded (compressed) properly. 1080p scaled down to 1280x720 will look just how its supposed to at 1920x1080 you just need to be closer to the screen. But then make that fit on 7" and 720p scaled down. That's just waisting space on the nexus7. a 30 minute anime file at 720p is generally 250-350mb. Its 1080p counterpart is usually 700mb. And it will look the same on your tablet. The only difference will be based on source material. TV capture vs blu-ray rip.
Then there is compressors. H264 8bit, h264 10 bit, divx, xvid, wmv, mpeg2. This will also define how the video looks. H264 10bit is the current best compressor. You can have a h264 10bit compressed lower (in megabytes) then h264 8bit and it will look just as good as its higher filer size h264 8bit. But naturally they will compress it less to completely blow h264 8bit out the water.
None of this has anything to do with scaling. Scaling down you see less but still looks very clean, and clear. Scaling up makes for a sloppy mess. And lesser you compress the less of a mess it will look but it will not ever look as good as native or less. And scaling of actual screen you should never see a difference as long as resolution of screen isn't touch.
There are two meanings for scaling and 1 for compression. Scaling resolution, scaling actual TV. Compression is only for file size which determines the actual quality. Overly compress it will look horrible. There is no under compress. Scale up from files resolution will degrade any image.

Maybe I should have made it clearer. Compression and scaling are different yes. Compression is taking a file size that is large and compressing it into a smaller size to fit. So taking a 1080P picture and watching it on the nexus 7 will look great. SCALING that 1080P picture to fit a 720P picture will change its resolution so that a 1920x1080 will fit on a 1280x720 size screen. Clarity will always go down regardless. Unless you are upstaging in which case it depends on your source. ENCODING is taking that same picture and converting into a different codec say xvid to avi. How you encode that picture (bitrate, codec,resolution) will determine the output quality. So bottom line 1080P will look better than 720P. But that's why I said don't sweat it on the nexus 7 because the difference will be minor. On a last note I stream Blu-ray rips at 10gb-15gb from my PC to my xbox all the time but unless your internet has an extremely high upload you will get choppy playback. Again sorry if I wasn't clear.

N7's resolution is 1280*800 and you should use 720p video as 1080p would just be a waste of space.

That's pretty much what I was trying to say lol but i load my movies on a flash and use an otg so I never actually lose my space on my nexus 7

Hello,
I'm trying to create a good preset in Handbrake for Videos to play on my Nexus 7. Can anyone tell me if I would get better results settings the picture size to 1920 (width) or 1280 (width)?
I know the N7 has a resolution 1920 x 1200 but I want to keep the file sizes reasonable whilst retaining decent HD quality?
I'm guessing that if I were to use 1280 x 720 the video would then be stretched to fill the screen thus making the reduced file size pretty redundnt?

I'm not really following you here.
The screen is 16:10, which means most stuff will run with small to medium sized black bars on the top and bottom of the screen while held in landscape. Old 4:3 AR stuff will have black bars at the sides.
If I personally were to make a trip where I wanted to take a lot of videos and didn't have a lot of storage capacity, I'd resize them to be 720p. Unless I were to output them to a TV later on. 1080p on that screen size, I can't really see the difference.
But my advice to you: try it out. Make some 1080p and 720p encodes and then have someone start a video and you have to try and guess if it is 1080p or 720p. If you guess right 50% of the time, do 720p.
I do all my videos at 720p with Handbrake and they look great on the N7. There is a lot of information out there about encoding settings. It comes down to personal preference and the amount of time you're willing to spend encoding videos.
I do most of my conversions at 720p with handbrake. The settings I change are: 1280 width loose / h.264 .mp4, check large file size if input is > 5GB / 18fps/ aac faacp & ac3 passthru (no need for the two audio tracks unless you use an Apple TV which will only use the 1st track)

On a screen this size you will be fine with 720. I have a 1080p projector and an 84" screen and I only notice a big difference with animated movies such as pixars or DreamWorks in 720 vs 1080.

Agreed. Even on my 40" LCD TV, 720p is plenty. So it is certainly enough for a tablet.
The extra resolution on these things is more useful for text based applications IMO. Video is fine at 720p.
I mean, 720p works just fine and all, but when it's docked it basically looks like you're taking a magnifying glass to the screen, as there's like a line between each pixel that's noticeably visible. You don't notice it in handheld obviously due to the size and resolution of that screen, but it can be annoying when it's hooked up into a 22' monitor that's right in front of muh face.
This build of Android is 1080p on the 720p screen & outputs 1080p unless you flash the 720p image.

Those spaces between each pixel are an effect of your display, not of the signal. The screen can't render natively in 720p unless it's a 720p screen, it can only render at its native resolution, which means the space between the pixels is the same no matter what.

My monitor is 1920x1080p. I don't get that effect with my PC or when I have my Switch running normally and hooked into it. Only when in Android mode does it do that.

You are 100% clueless. This build of Android is 1080p only unless you manually change the resolution with an app or flash the 720p image.

That is completely besides the point. I wasn't talking about the ROM at all because it's irrelevant; it's simply not possible for a lower resolution to cause the effect they're describing.
Yeah LCD have fixed resolution. the space between pixel won't become easier to see when it's taking low resolution feed
The version of android I'm using seems to be 720p regardless of if it's docked or not and 60fps portable but only 30fps docked... I use the app screen resize to force 1080p when docked.
Where can I find the build that auto switches to 1080p when docked?
