Hey guys, the camera seems pretty good on this phone when I'm taking pictures, however when I am taking videos it almost seems kind of grainy even though its suppose to be 1080p. Anyone else have the similar or different experiences? Please share!
Grain doesn't have much to do with resolution. What affects grain directly is light. Low light will give you more grain. Period. This is valid for professional cameras as well.
Shoot a video I good light and the quality is excellent.
Don't use 1080p it's crap and makes videos look awful. They decided to zoom the picture in about 40-60% and not allow you to zoom out. As a result everything looks grainy and out of focus.
Set ur camera to 720p look at how much you can see, how clear the image is how sharp the colors are etc and then switch to 1080p and you will find all the sudden you zoomed way in and can't zoom out and the picture quality dropped about 60%.
They claim 1080p support but it's a lie since they zoom in and give you a MUCH lower quality video than 720p does.
How do you switch to 720p mode?

I'm pretty sure that's just a big nasty bug. The camera sensor and chipset are all very capable of 1080. It seems like the 1080 is zoomed into the amount of area that 720 would take in the middle of a 1080 image...I won't say it's an honest mistake, as it's borderline retarded...but, if it is dumping 1080p worth of data it can certainly do 1080p video...that's only 2mp and the tough part is writing that to storage without it getting skippy...and clearly that can be done.
Though I am assuming it is writing a 1080p file...has anyone checked?

GoPro HD also does this. Few of my friend's digital point and shoots did this as well. So, it's a sensor issue, not a software one.
I posted this before:

Pardon my breathing, sinuses FTL
I really wish there was a way an external microphone could be used while recording video.
My problem is with the recorded audio. Has anyone found an app that let's you control audio gain. Serious clipping for live music records.
Its the quality (bitrate) in which the audio is recorded. At stock, its set at 64kbps and a sample rate of 44kHZ which is pretty subpar.
There's a hacked camera apk that lets you record audio at 194kbps with sample rate of 48kHz and also raises the video bitrate by a tad as well.
A tremendous difference in quality.
The graininess is caused by poor lighting. I went to sea world with my girl this week and all the outside video's came out amazing. But, inside shots with low light all came out very grainy. I can't blame the sensor too much because like someone mention before the same happens on high end camera's. But, also remember professional shots are taking with very high end lighting equipment.

I can't seem to find anything like what you're referring to anywhere in the market or our app section. Got a link or a file name? Thanks.

and if u search our ET4G forum, you'll see a thread about it.
MUST BE ROOTED.
Is it just me or does picture quality significantly decrease when you use the zoom? Even the slightest zoom causes the image to display heavy pixelation. I'm running stock 4.0.4.
Digital zoom is always going to quickly degrade the quality of the picture.
Ah... yes. I guess i'm used to my point and shoot camera having a small amount of optical zoom. thanks
Hey guys,
So a friend was showing off slow-motion recording on his Note II and I remembered "Hey my phone has that too"
I didn't actually record that time, but we had gone to the beach at night much later. I tried recording a video in slow motion. The lighting seemed enough when I viewed it from the phone, but as soon as I start recording the video in slow motion, the whole thing is dark. Now my question is why does it get dark in slow motion recording? I know the resolution drops but I have no idea why it gets darker. I could have snapped photos with the light present at that time, and the photos would be much better than how the recording came out.
Its more like when snapping pictures or taking normal videos in low-light, all is good. But for some reason in slow-motion mode the camera doesn't get enough light so the video appears dark. And Switching to Night-Mode Scene helped very little.
It needs to lower exposure to maintain the frame rate

This is the same with any high fps camera ever. To compensate for the higher fps you need to lower the resolution or exposure.
I've seen in some reviews and spec sheets on the G4 that it has HDR video capability. But after digging around in the camera's limited options I just don't see it. Is there some way to do this with an alternate camera app?
There is no such thing as HDR for videos yet. The experiment that comes close to this would have been a researcher who used two Canon 5D Mark 2. He shot videos with different exposure on each camera and attempted to combine the videos. It didn't work well.
maybe they can implement a function to alternate exposure between frames, so exposure goes -3, 0, +3, 0, -3, ...
Actually my old 2013 HTC One M7 has HDR video. It takes two different exposure frames, then tries to combine them and stabilize for motion between them. This causes the overall field of view to be cropped a bit. I think some other phones in the past couple years have this feature too.
Wow, interesting. I had assumed HDR video was not possible. I hadn't considered constantly bracketing the exposure using individual frames.
It seems like this would at least partially reduce your effective framerate? Say you have 2 moving items in the shot, one bright, one dark, along with a neutral-brightness background. The background might be correct in 0EV frame 1, dark subject correct in +3EV frame 2, bright subject correct in -3EV frame 3, and so on. But the subjects are moving, the bright subject is somewhat ignored in frame 2, and the dark one ignored in frame 3. So the moving bright/dark items might appear slightly jerky, as they are not properly captured in all 30 or 60 frames captured during that second.
But it's interesting, regardless, that this can be done. With more processing power available in the future, and maybe a higher-framerate camera, plus some fancy image-processing, maybe HDR video will become more practical.
I know I'm a bit late to the party, since I too was researching how to shoot hdr video on the g4, sadly there isn't. But the S6 and S7 both can shoot hdr video, take a look

HDR version horror bad.
Oversharpening and over saturated. blury....
4K much better.But OIS not to effective.
Anyway great quality thanks mate!
The HDR to me looks pretty decent given the advantages of boosting the shadows, yeah it's oversharpened and over saturated but other than that, it makes a huge difference. Just wish LG implemented HDR video as well.

Hello,
Im looking to upgrade my Nexus 5 and ive been going through lots and lots of reviews, videos, pictures of many of the new phones out right now. Z5, S6, Nexus 5X.
I really like the Nexus 5X despite some of it shortcomings but one thing i REALLY have a hard time accepting is how shaky the picture is when recording video compared to iphone 6s, Sony Z5 and others.
Here is a video showing it against the Moto X pure:
https://www.youtube.com/watch?v=l_zth08zFLw
The Nexus 5x i horrible Is that something we will just have to accept because it lacks OIS or is it possible to fix software wise in a camera update or using a 3rd party camera app. I must say that in its current form its unusable.
Regards
Jacob
indeed it is shaky...
haven't tried it but this one has video stabilization - https://play.google.com/store/apps/details?id=net.sourceforge.opencamera
Maybe someone with a nexus 5x could try opencamera to record a video and post the result?
Yeah I was hoping 1080p would at least get decent software stability. It has enough pixels for it. ?

Does anyone know? Anyone tried opencamera?
Just my $.02. It was my understanding from the Launch event that it doesn't have image stabilization. Something about how it didn't need it with the upgraded light gathering capability of the camera.
The Moto X pure doesn't have OIS either, it's done in software
I'll just splurge for a gimbal. LOL

Just tried it and it seems decent. Good thing is that OpenCamera properly implements the sensor orientation detection, so the preview and resulting files are correct. It has experimental support for Camera 2 API, which needs to be enabled in order to expose the EIS setting.
At high resolution (4k), there's significant lag that's recorded in the videos with the EIS enabled. Google did say the 808 couldn't handle it; maybe they weren't just blowing smoke?
At 1080p, it seems to help reduce the shakiness by a fair amount; it's no OIS replacement for sure, but I'd say better than not having anything.
Funny how google said larger pixels negated the need for OIS. Did anyone really believe them? Did HTC not try the super mega sized pixels before?

From pics I saw it does fine without OIS. But videos would have benefited. And yes they coined it as "ultra-pixels".

OIS is only really of benefit for photos at shutter speeds less than 1/60th second, unless you have a zoom lens, where it is helpful at higher shutter speeds, as the more you are zoomed, the more amplified any body shake is. For smartphones with their wide angle view, camera shake is not too much of a problem for most typical situations, and any daytime scene OIS is completely pointless as the shutter speed is plenty high enough to freeze out any camera shake. The larger pixels help as the ISO can be higher without too much noise meaning a faster shutter speed can be used.
For video the situation is different as images are taken over time, so it's the movement in camera position between each picture that needs to smoothed, although the fashion these days on most documentaries and TV shows is to deliberately shake the camera around until it's a nauseating mess with whip zooms into the mix Still it's a good indicator I find for knowing the program is trash and not worth watching :victory:
OIS in smart phones helps a little with video, but the tiny lens optics and limited movement means they don't do nearly as well as a dedicated camcorder with OIS, which gives some amazing results. The link to the stablised 5X video is using a $300 device, so if anyone is that serious about their smart phone video, then for that money we might as well take a much bigger step in image quality and convenience and features and get a dedicated camcorder.
The elephant in the room with the Nexus 6P is EIS, this is the poor mans image stabilizer, yes it does help stabilize the video to a certain degree, but to do this it has to crop the image. It appears to be doing this the cheap way in software (hence needing the powerful chip), taking a 1080P video, then zooming into so it can have a window of view to pan around in, this means the resulting video has less resolution, see the clips here https://youtu.be/HV4rcFuUlUc?t=246 and compare the detail between the two, there is a drop in resolution on the 6P. Better EIS systems capture a larger image at the sensor, then would track and pan a 1920x1080 window across it so no resolution drop, but that requires more low level work with the camera hardware and dedicated chips to do a good job.
Record a 1080P video with the 5X, upload to YouTube and get it to apply stabilization and it will do the same thing, may even turn out better than the 6P EIS as it doesn't need to be done in real time so a bit more care can be taken.
Will the 6P stabilize 4K video? I somehow doubt it has the power to do that, so for 4K it's an even playing field between the two.

Hmm, aren't those phones using the much higher resolution of the sensor (at least about 4k) to stabilize the video by changing the captured frame on the sensor corresponding to the phones movement? At least i thought that's the reasoning why this works only up to 1080p (which would be preserved, in that case).
I think this could be quite useful for the next Nexus http://techcrunch.com/2015/01/09/imint-wants-to-bring-real-time-video-stabilization-to-android/
