Anyone know if a way of zooming in the video while keeping it at 1080p like the N8 does. I could do with narrowing the view 2 or 2.5 times for an experiment.
It works with normal digital zoom, but loses quality.

sure is possibile but you will always lose quality becose the video sensor of the xperia s is digital not optic the video is at 1080p but with spixelation there is no altrnative way!

I know the usual digital zoom will drop quality, which is why I'm asking.
The Nokia N8 has a sensor area zoom.
So the normal ( like the S) view uses the whole sensor sampled to 1920x1080.
Zooming in uses a smaller and smaller area of the sensor, until it reaches the actual 1920x1080 pixel area of the sensor.
In theory you loose very little quality.
I'm hoping there's some way to do the same on the S, instead of using the entire sensor, just using the middle 3Mp or so to keep the quality, while narrowing the FOV.
What would be even better would be if I could change the aspect too.

Is it me or does our camcorder suck?? I recorded my dog in the house blinds were open and everything so I can have light in the house but my video still came out dark which is crazy really starting to think our camera is wack I love the phone don't get me wrong but I'm considering trading it in I mean its like I have to be outside to get decent quality....in the daytime anyway

Maybe too much light or cam was pointing the bright areas. All cameras will do this. The shutter is taking in all that light.

I'm a professional video producer and hobby photographer. I haven't tested the Evo 3D's camera for video yet, but the problem you described is common in all auto cameras.
When a camera is automatically adjusting exposure, shutter, iso, etc. it adjusts for the brightest dominant subject in frame. The camera thinks you want everything perfectly exposed and is programmed not to blow out the highlights. So, what happens is it sees the bright window and thinks "ok, lets expose to that so it isn't a white blob." If you want to avoid this type of thing, lighting has to be as even as possible to the windows (which is almost always impossible) or you frame your subject without the window in the background. You also avoid this by using manual exposure settings, but I'm not sure how much control you'll have on the E3D.
What I would be weary of is the bitrate the E3D records video at. HD is only a resolution, but if it's a crappy bitrate, the video will look like crap. If you're not familiar with that, search youtube for some sample clips of videos in different bitrates. This probably can't be adjusted in the settings, but might be adjusted with some development if this is lacking. I remember when I was on my Samsung Moment which was android 2.1, that was adjusted in the build.prop but I don't know if that's the same here.
EDIT:
Some examples of what I described -
Bitrate comparrisons:http://www.youtube.com/watch?v=0xNG6gw4cxU
Some background to the above clip, this is testing the Q scale of a hacked firmware for a DSLR. The Q scale is just the piece of the firmware that controls the video compression/bitrate. The lower it is set, the higher the bitrate it uses. He starts at about a 44Mbps bitrate in the above video and moves down to about 10Mbps or lower. I'd be surprised if the E3D records even 2 or 3 Mbps. But if you jump from the beginning to about 1 min 30 sec. you can see the difference more. Watching it through, the changes are so subtle you might not notice much.
Couldn't find a video to demonstrate, but this forum post about the subject might help:

No problem. There's a lot to factor into better low-light picture. The tiny lens on mobile phones doesn't help. The new Mytouch HTC just released this summer has a back-lit sensor which lets more light hit the sensor, for example (the sensor is built backwards so the wiring is behind it - in a nut-shell). It's like a "duh" technology but JUST emerged recently. A lot of cameras compensate by adjusting the ISO (digital equivalent to film speed or sensitivity to light) but that causes more noise/fuzz to appear. You may want to try that though if you can for video, I know you can on photos. But feel free to ask me anything about video or photography and I'll do my best to respond. I don't sign in to XDA often, but I'd be glad to exchange emails or something.
Turn up the exposure, under image adjustments.
Does wonders for me.

I did I mess with all the settings .....stop not satisfied lol .....just think HTC could if done better I know back in the day BAKED SNACK would tweak the camera and camcorder to make it better....just hope eventually the devs will do the same

That's the only settings change I would make to get the best results, aside from dancing with a higher ISO... I keep it at max on both the camera & camcorder.

Hey guys I was testing our 1080 p and noticed that our camera was horrible when looking at things with lights like a TV screen or something you really couldn't see anything on there it just looked very bright. It happens when your filming people and there's a light in the background also it just shows up as a huge glare and its horrible. It's on all roms and I think its just the camera in general. My friend also has this phone and I tested it and it resulted in the same thing. Light sources are being shown to much I guess and trust me it's horrible to try and show off your phone and claiming to have one of the best phones in the world and your camera 1080p is filming horribly. It's retarded as hell and up until this discovery I've had no complaints about this phone. So my question is what can we do to fix this. I've tried lowering the EV Control to negative 2 and it still gave the glare. Do we have to wait for an update to fix this problem or what.

are you on stock or custom rom? i am on unnamed v2.2.1 and having 'continous autofocus' issue during 1080p shooting that makes the video blurry and sticky.i have posted this in unnamed dev forum.
meanwhile, as a workaround i use 720p mode that somehow makes video kinda okay.

This problem can not be fixed.
The detector has a limited dynamic range- smaller pixels have lower dynamic range. The lens needs to be small, otherwise the device isn't pocket friendly. Lens size must be matched to pixel size, so even if a manufacturer wanted to include a high dynamic range imager in a cellphone, size-constraints make it unlikely.
It isn't realistic to expect a phone camera to compare in quality to a dedicated (and larger device) camera.

That's not relevant at all. There are multiple phones that have great cameras such as the Xperia arc. And I expect a device that outperforms others. That's why I bought this phone. And even my old Xperia x10 camera was able to cover white balance a lot better in certain areas. Our camera should be better. It takes great still shots but horrible video in lighted areas I guess. It doesn't make sense.

If someone could modify the Camera to accept tap to focus and exposure in video mode it would be perfect. That's what the issue is. However, I notice that during recording it is a LOT better than what it is when you just set video mode and look at it.

I just don't get how we have one of the greatest cameras and it does this bad with white balance. And yes I noticed the recording thing too

Ive heard that if you use the camera in widescreen, you don't get the full 8mp, but can't seem to find any details. Anyone know what's up with that?
It crops it to fit the screen. 4:3 is the full 8mp so basically it just cuts the top and bottom off so it fits the screen better and u lose some of the image

That's hysterical. Is it the same for video?
Well I'm not sure but my guess is no. The video isn't at the full resolution of the sensor its either 720p or 1080p in 16:9 aspect ratio. I guess it could do video in 4:3 too for a fuller image but its not really an issue ppl prefer widescreen that's the way it works. The sensors are made for 4:3 max (i believe) so they can't add to it to get more so they have to cut off the top and bottom to make it fit like all phones work. Not a problem with the LTE that's how its supposed to be every smartphone works like that

Is there a way to take 12mp photos in the same aspect ratio as the screen, rather than have to stick with 9mp for that? Thanks
Sent from my LT26i using xda premium
No.
I take my pictures at 6mp so what's wrong with 9mp? The quality isn't less good then on 12mp you can barely see a difference
It's not that a normal Xperia S user will take pictures to show on a giant screen

Its not normal, but I do occasiomaly use larger screens but thanks, 9mp is indeed still great, and MILES ahead of any other phone ive seen

But why Sony designed the 12MP camera when it is actually not optimized on Xperia S screen (i.e. full screen)?

Xperia S screen is actually 0.9MP (720*1280=921600). Any picture taken with larger resulution is not possible to display without reduction in size. That's the first reason.
The second one is that 12MP has 4000x3000 pixels with aspect ratio 4:3 while the screen is 9:16 (or 16:9 in landscape).
Hope this helps.

Guys, I'm also interested in one thing, I'm newbie photographer but I'm doing well in taking pictures, but I wonder one thing, which resolution is better for photography 12 or 9mp, I see there is not big difference in resolution since 12mp is 4000x3000 and 9mp is 4000x2250 << please help with it.

It depends on whatever you like best. I use 9mp, cause it's the same aspect ratio as my phone and my TV.
Thanks, I like 12mp because of details, but 9mp more modern I think, 4:3 resolutions looks a bit ugly, and I dont loose much details 750Pixels not big deal
Also, the more megapixels you have, the more chance you have of getting more noiee2!
I always use 9mp on my XS, because it's still better than most camera phones out at the moment! (IMO)
Sent from my LT26i using xda premium
To get 16:9 12 mp you will need more than 13.333 mp sensor to do so .
Or just simply upscale to 12mp from 9mp .

There is no difference in quality/details/noise whether you use 9 or 12mp. The only difference is that when set at 9mp, the image will be cropped to the 4000*2250 size. That means you lose 1.5mp (4000*375 pixels) from the top of the image and the same from the bottom just to get the 16:9 aspect ratio, resulting in a narrower field of view.
So basically a 9mp photo from our xperia S is the same as a 12mp photo cropped with photoshop for example, to make it have a 16:9 aspect ratio.
Hey its me again, I still didnt solve my pervious problem and here is another one!
I have hot pixels on my front camera sensor! I attatched a picture of me hanging out with a friend and you can clearly see the hot lixels EVERYWHERE! It doesnt hapen in indoor shots nor with the back camera. Should I take it back (the phone)?
I am starting to think that I bought a crappy phone I mean it get hot as hell, I have cellular issues, and now the camera? WTF! K should have bought the One X
That's Normal,the front camera have a low resolution sensor.
Use the back camera.

No no no. It cant be a low resolution problem. In lower light conditions, the photos ale less crisp of course, but dont have theese white dots all over them. I think the sensor might be oversensitive to light or something
Front camera is always bad quality.
It has been designed for HD video, not clear picture camera for every day use.

Front cameras should't be so noisy.
My girlfriend iPhone 4S makes bit noisy and blurred photos, but no hot pixels.
