Just to start a discussion.
everyone knows N1 is capable of doing video recording on 720p.
I am just wondering, why google does not officially release such capability? Or do you think they just want user to root it and do whatever they want? Desire has it anyway.
I am so looking forward to an official 720p, if it ever happens.
Because of the bit rate and frame rate. It's not good enough to do it over 24 FPS consistently.

ok, that too. ;-)
it does a really nice job @ 800xwhatever, but 720p is just too much. it starts having artifacts if there is any motion at all, and any panning/tilting turns the picture terrible. just what i've experienced.
using the latest CM6 nightly i have yet to come across any issues with it, i actually like it, but yea compare it to a real HD camera (not the Evo) but a handheld camera the 720p is crap

Yeah. But that's obvious. You spend probably around 300 for a good 720p camera ya know?
I hate to bring it up, but why can the iPhone 4 handle HD video so well? It has a 5MP sensor just like the N1. Any ideas? Because I know this sensor could handle it if the iPhone's could. Am I wrong?

Well rooted N1s and desires are able to do it. Better than what HTC gave in the official froyo update too.

I don't think it's the sensor. I think it has to do with how fast the phone can take data from that sensor and do something with it. It can't keep up with the camera flooding it with data at 24 FPS at 720p.

A bit better (and closer to the truth) explanation would be:
Google have X engineering "horsepower" that can only do Y stuff in a given amount of time. They can:
1) Spend more time upgrading their DEVELOPER phone capabilities (which was never intended to be anything but developer phone) for the sake of the VERY FEW customers that bought this phone while it was in commercial stage (Nexus owners are a tiny percentage of Android device owners),
2) Spend more time enhancing Android system for ALL the current and future customers of ALL phone manufacturers.
Guess which one they would prefer? Not a hard guess, right?
Yes, unfortunately, it's not the one you would prefer.
The same goes for "why not improved graphics driver", "why not improved N support", etc.
I 2nd that.I think that Google engineers are more into improving android os as a whole.
OP,didn't you notice how many updates and radios the desire has compared to ours?

The iphone4 does 720p and movement really, really well, i was shocked, and admittedly a little jealous. When it is said that the Iphone4's "hardware" is better, is it that the I4's hardware has better quality, or does it just have better specs? In other words, the I4 doesnt have a full ghz processor right? But is it just much better quality? I dont really know what im talking about im just very interested in 720/HD recording on smartphones, definitely a prerequisite going forward...thanks

yeah, even when I tested the iPhone 2G camera that has 2MP sensor, it's photo quality was alot better than my Nexus. just the resolution is bigger in Nexus. and iPhone 4 has a Apple A4 1 GHZ processor, that equals almost the same CPU on Nexus but with different GPU on iPhone (PowerVR SGX). it just does it really really well.
The CPU and its main frequency has exactly nothing to do w/ video encoding, most probably. Encoding/decoding in small-scale devices is usually implemented by separate subsystems (packaged with the CPU - that's why they call it SoC).

i see, so Apple spent a good deal of efforts to specifically make the camera so good...It wasnt just that they made the phone well, and in turn that solid hardware allowed for good camera quality.
I dont even use the N1 video recorder very often but for some reason I really want better capabilities, maybe if I did have much higher fps and resolution I would use it a lot. Currently the fps are really poor, any movement is a blur regardless of the amount of light. And of course 480 is quite dated. But the phone is otherwise top notch, and the 5mp camera is really solid and i use it a lot, under varied conditions.
I imagine the internal memory vs. whatever SD card a normal consumer would get might also play a part. The Android devices that do have 720p officially all have internal memory ( >1GB ), right? So the manufacturers can control the quality of memory used. I would think that Google/HTC would get lots more complaints from the general population who got bargain basement cards from the back of a truck and expected everything to perform flawlessly. I also agree with above points about the hardware and subsystems. So many variables. But that's also why I like the Android platform. You have a choice (and not just 16GB vs. 32GB locked to one carrier with a contract).

IF I remember correctly, Charansingh said the Iphone achieved 720p by duplicating the image thereby increasing fps to achieve 720p...or something like that. The amount of available light controls the phones ability to reach higher fps. I've gotten 26fps outdoors in bright light. The N1 is set to a max of 30fps, but will only do 1/2 of that indoors. fwiw

Yeah, 1080p isn't a dealbreaker for me. I don't honestly still see much difference on a good, well calibrated 720 vs 1080p screens. Probably people with perfect 20/20 vision are the ones who swear they see it, but anyways, I'm more than good with 720p
If they switch to pentile instead of rgb, doesn't matter if it's 1080p, would surely feel awful tbh. Hate pentile displays

Actually, it is possible to increase brightness of AMOLEDs a lot - but that would degrade the screen super-fast. Hence the low brightness levels/limits. And obviously the battery drain would be massive considering the whites draining a lot of battery already.
I honestly cannot see the point in a 1080p screen on a phone, not that it is a bad thing by any means, but I find the current resolution more than adequate and more pixels mean higher battery drain/more stress on the gpu.

Basically, axiom of non-satiation says "more is better".

Apparently some people have super vision and can see the pixels even in a 440DPI screen. (not joking)
Well (un)luckily, I don't even have 20/20 vision (still pretty decent eyesight, mind) and I'm good with my Note 2
I think lot of the "way too obvious" differences people notice are mere placebo effect. I mean 440ppi full HD? That HAS to be WAY better right? Seeing what they want to see etc. But yeah, probably there are people with perfect super vision who can make out the difference.

1080p contend is supported more often from apps because of the amount of supported devices, I wondered if downscaling the tablet's screen resolution to 1080p is supported by any rom and if it would save a few hours of extra usage to the tablet?

I am no expert but I know that when you give the command to change the resolution it doesn't actually change it, it's more of a virtual/spoofing, to make the system think it's changed. So all the pixels will still be there. But when watching videos in 1080p the "upscaling" won't take much of your battery, if any at all. You won't notice it.
A digital screen only has 1 resolution. To use any alternate resolution it must be scaled to the screens native resolution so if you were to somehow force a resolution other then the native it would have to re-scale it to the native in order to display it which would require additional processing...
You could get better performance, in 3D applications for example but not better battery life.
I am asking for the SoC power consumption,logic says less effort saves more energy,current pixels to handle are about 4 million instead of the half that 1080p are
Though there might be needed optimizations as a modded kernel with different clock speeds

"Logic" that's ill-informed can be just as fallacious as a random guess. Your particular brand is working off of some very silly assumptions, and your second sentence really just highlights that. A modded kernel with different clock speeds? Please.
When you downscale an image, you have less pixels to handle only in the sense that the image becomes smaller. The actual display still requires that all of the physical pixels be addressed before it can display anything. The only reason that you see graphical performance improve in say, a computer video game when you're playing on a lower resolution is when the bottleneck is the graphics card rendering an image. If your computer is struggling with the output, then you have a different set of problems.
On a tablet, a game that's not built to the screen resolution (let's say it's designed for a 720p panel for the sake of argument) will keep load fairly light on the GPU for rendering, but the same amount of work as normal to display (although this is a simplification, it'll work for these purposes). That's because whether the content is 720p or 1080p doesn't matter-- the GPU still needs to figure out how to stretch it to the dimensions of the physical screen.
Bottom line, you're not going to save "a few hours" of usage. All the work you'd need to do normally will still be there, plus the chicanery of trying to transform all video output to 1080p again only for the physical screen to demand its normal resolution.

This! I know I was playing Dead trigger and you can enable the advanced graphics for tegra gpus, and it was laggy, but after reducing the resolution (the game doesn't allow this, or didn't the last time I played it) the game was buttery smooth.
And no, video decoding doesn't care what resolution your screen is. It still has to decode the whole video and display all the pixels, weather they are upscaled or not. your battery won't be affected by that. Apps on the other hand, like games, are another story.

Not sure what's worse, clueless people on a site called XDA-Developers or clueless people who refuse to listen to advice.
Whether the iPad has some kind of overheating issue is a completely different matter and can be caused by a number of things. The fact is that changing your screen's render resolution has almost no impact on your battery life. The GPU still has to upscale whatever is rendered to the Nexus 10's native resolution. The biggest drain on the battery is the display itself; it takes a lot of energy to light up a display with such a high pixel density and still be bright enough to see.
Irony is the worst of all,at least some people know what a question is as this thread is
When you ask a question you need to be able to accept an answer that isn't on your liking. You've had 5 people telling you in different ways that it won't help, if you don't want to believe us, then here you go this doesn't work on 4.3, just 4.2 and maybe earlier. You can change it and use it for a week and see for yourself. Just make sure you don't let autosuggestion cloud your judgement.

Ahaha, says the new member who has demonstrated 1) that they don't know what irony is, and 2) that they have no idea how to ask for help. Hint: it's not "please validate my preconceptions." The only irony here is your reactions to the thread that you spawned.
My iPad has never overheated, or even come close, really. It's the same crowd of people who will complain any device "overheats" when they're doing something that is going to create thermal load. Newsflash: that will be just about any game or long-term video ever. The 1080p Nexus 7 gets warm under use as well-- oh wait, 1080p is some magical resolution that will fix all your woes, right?
Protip: overheating doesn't mean power loss unless your circuitry gets pushed outside of standard operating conditions and loses conductivity due to thermal deformation. On a desktop PC, it might mean power loss from running the fans up, but as mobile SoCs use passive dissipation, this is a non-starter. Heat buildup is a byproduct of using a processor to do things.

Something I learnt is that if you lover the resolution you will NOT get any bump in your battery life. That's because the device upscales the 1080p res to 2K. Also, the processor is capable to run 2K 2D Contents (such as text, webview, certain UI elements etc) without any kind of problem. Only 3D contents such as games could be greatly affected by this.
Hi all,
I personally don't think there's much difference between 2.5K and 1080p on a ~5 inch display. Has anyone with root found a way to and tried down scaling the display output to 1080p?
If so do you notice any visible difference and has it noticeably improved battery life?
I'm not convinced how much difference it would make as the display itself would still be physically outputting 2.5K pixels but at least the processing side of things would only need to push 1080p.
Thanks!

I searched for an answer to the same question. I doubt it's have much impact on battery life honestly. The gpu isn't working as hard, but that's not the biggest drain by far. The best reason to do this would be improved performance in gpu-intensive activities like gaming. However with this phone that hardly seems necessary.
(I suppose, theoretically, you might get better battery life during gaming)

My guess is the won't matter because the GPU will need to work just as hard. The number of pixels you push to the screen will always need to be converted to the number of pixels the screen is designed for. Pixels are more hardware related than software related.
A screen has several tiny LED's that illuminate to display the image on the screen. The 6p resolution is 2560x1440 which equates to roughly 3.7 million pixels. It has to display 3.7 million pixels. 1080 equates 2.1 million pixels but the 6p has to display 3.7 even if you only push 2.1 million pixels to it.
Depending on how well the Android OS is designed it wouldn't be out of the realm of reason to say that dropping the resolution to 1080 might reduce battery life instead of save it depending on how well the code is reused internally and where the interpretation of scaling happens in the chain.
I talk out my ass a lot so I am only guessing that the above is true.
Downscaling to 1080p won't do much for battery , the pixels still need to be lit, but the GPU will be less stressed, it doesn't have to render those extra pixels with new information, its just upscales

That's my understanding as well. It's still rendering at lower resolution, which requires less from the gpu, but then upscales to the native resolution. I'd still suspect this will improve battery while gaming, but not in general use. Entirely direction though.
It won´t look good on the screen, that´s for sure. Downscaling might only be needed if you want to play a heavy game which wouldn´t run fluid enough on the Nexus 6P, due to hardware limitations.
