Hi guys
i have noticed that when light is low, the frame rate drops in (what i believe)an effort to combat noise. this make the picture stutter. any way of fixing it to keep the frame rate constant?
and white balance set to daylight just makes every thing yellow. its called white balance, not yellow balance. any ideas on fixing that?
sigh...
no one...?
Can you give us details on what is your problem

For video: when light is low, the frame rate drops below 24 per second. this makes the video look stuttery, and cause major blurring.
as for the white balance, both video and still are affected. by that i mean that when white balance is set to daylight and if i was to take a picture of a white sheet of paper in daylight, it will have a yellow cast. i will try and upload a sample as soon as i can.
i dont use auto white balance cos its never constant
I think because there is essentially no "shutter" the fps is what suffers. Essentially smearing your video. Its replicating a 1/24sec shutter by dropping the FramesPerSec. Maybe try doing a spot light instead of center weighted exp. And set iso to 800. I'm thinking how the Sii can launcher handled it but then again 8mp>1.2mp

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:

@GK1984 THANKS A LOT your info makes sense even tho imo my EVO 3d camera is kinda wack ....specially in low light

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.

I love my new Amaze. As with any device,though, there are a few issues. One that's been nagging me is what I would describe as excessive contrast. In other words, at 50% brightness the dark areas of a video are so dark that it's impossible to make out any detail. Raising the brightness to 100% helps some, but its still hard to make out details and the whites become blindingly bright. That also causes a lot of battery drain. Is there any way to increase the detail of dark areas of the screen without dialing up supernova brightness?

I tried to find an application that does this, but apparently, they don't have an application that can play a video and be able to change video settings such as contrast.
The only solution as of now might be processing your video before watching it. This would be ideal if you are putting a movie on the phone, but not so much if you are playing a video that you previously took.
I'm not sure of programs that can process the video, but I'm sure that a quick search on google should do it. Watch out though, as some programs will actually watermark the processed video and make it ugly.
Hi I just got the S3 and I've noticed that my camera is very grainy, much more so than my S2. I've tried fiddling with the settings and can't seem to fix it. I'm wondering, has anyone else has had this and has found a way to fix it? Thanks
Is auto contrast switched off?
Sent from my GT-I9300 using xda premium
Yeah it is. I've tried it with both and it doesn't seem to make much of a difference.
Are the pics at night or day? On my one x the dark images r really grainy. The higher the ISO is set to eg 1200 the grainier they are aswell.
it may be the iso. It was inside but I took a picture of the same scene with both phones and the S3 was very grainy. I think I need to find a mixture of ISO and exposure. At the same time I can't see me getting it to the same level as my S2 which worries me. It's a bit strange.
another thing to check is if the ANTIVIBRATION is set to on
when you set on, you can immediately see (specially in low light) an increment of grain, i think because the antivibration is just a boost of the iso
I know there are plenty of photographers or just people in general that found the perfect combination of settings in the camera app. I'm talking about the settings like exposure, contrast, saturation, sharpness and ISO. Any recommendations, and just post the ones that you've found work the best!
I'm no professional, but I know that your settings are going to vary based on the setting. There won't be a "one-setting-fits-all" setup that you can plug in and get a perfect picture every time. You'll have to experiment.

Yeah that's true, I was just hoping people would post multiple setups and maybe pictures to compliment the setups
Sharpness, Contrast, and Saturation should be done post processing, and sparingly. Exposure and ISO depend on your light and speed requirements. These should vary with each shot (just like Auto tries to do). Higher ISO's can prevent blur (better for fast moving objects), but are noisier. Typically go for the lowest ISO you can, and hold the camera as steady as possible. If backlighting is hosing up your shots, you can manually adjust exposure to compensate.
Edit.... that being said, I typically take Sat down a notch when shooting people to avoid that red hue these phones get on skin tones. Even though the red doesn't come out as harsh on a computer, it just looks better when viewing on the phone. Nature shots look awesome though with the normal setting.
I knock saturation down one notch and it seems to make skin tones etc more natural and remove the red tone I was getting with indoor photos
I just got my GPe and I'm very disappointed with it. It has a yellow tint screen and as I understand there isnt White balance setting on GPE. It also has a problem with the camera. When I'm taking picture, the on screen viewfinder shows a lot of noise. But when I review the pictures, the noise disappeared. Anyone has the same problem?
Post processing noise reduction reduces the noise. So it's a good thing

I understand that but during the process of taking picture. There are a lot of noise on the screen. I've never seen anything like this on any other phone.
Yes it's because we have a small lens. The actual image will be much better than that on the viewfinder. It's how Sony does things nowadays. Basically if you took a picture normally without any post processing, you would have gotten that image but since there is noise reduction, we get a better one. It's a small measure to tackle the fact that low light absolutely sucks on this camera
