Hi,
I believe that the Snapdragon 800 msm8974 CPU SoC used by the G2 supports video encoding up to 120fps 1080p video or 30fps 4K video. Indeed the Note 3 which also uses the Snapdragon 800 can record 4k. Whilst 4k recording isnt of much use at the moment, 120fps 1080p video would be!
Any thoughts on whether an app can be developed to tap into that functionality or would it require a firmware update from LG?
Thanks
Would love to know this as well
Is the camera even capable of it?
Bump! - ya, why did LG not include 120fps? the hardware fully supports it..
Im swapping my Note 3 for a G2 as soon as VZW drops the white one, and no 120fps kinda bums me out.
Bump again. I was reading a review on AnandTech and they said LG only enabled up to 1080p60 since the sensor can handle it. Does that mean the sensor can't handle 1080p120? What about 720p120? A friend of mine showed me the slow-mo on his 5s and it looked better than the slo-mo we can do on the G2, which I'm assuming is because of the 120fps. Would love 120fps, even if it's at 720p. It would be something I would root this phone for.
Slow mo?

Yeah, what happens is that the video is shot at 120fps and he slowed the video down, similar to how we can slow play speed. The video is played at 60fps in slo-mo and looked a lot smoother and less grainy than the video on the G2.
I'd like to know too if our device(D802) can hande [email protected] as [email protected] is quite the same amount of data to process

I've seen a modified camera app for the lg g2 here on XDA. The developer tried to make more than 60 fps and in the next version of the changelog he put it back to 60 fps cause LG "limits" the fps to 60. Too bad.
But he says that is an HW limit or it's limited by SW? :crying:

1) Back Camera Records 720P Videos @ 90 FPS. [Broken- Max FPS limited by LG is 60]
You can check it out at (V_2.5.6 EXPT_3 Details):

LG G2 has Sony IMX135 sensor which support max:
1080p30 (HDR) | 1080p60 | 720p60
So LG is not blocking anything it is HW related thing!
The Samsung Note 3 that records 4k vids also has the Sony IMX135 sensor:
http://image-sensors-world.blogspot.se/2013/10/samsung-galaxy-note-3-features-latest.html
Anandtech is usually correct too:
"There’s an IMX135 sensor inside the Note 3..."
"On the video side of the Note 3 we have an interesting new addition, 4k30 (or UHD) video record support, alongside both 1080p60 and 720p120"
http://www.anandtech.com/show/7376/samsung-galaxy-note-3-review/6
/EDIT
A mod for the Note 3 allows 4k recording up to 100Mbit!
Over 4Gbyte on exFAT cards, though not an option on the G2.

Hi!
I have a question.
I have a galaxy s4 i9505 and want record in slow motion 720p but the quality its very poor.
In other case, the Moto x first generation have only dual core, but can record on 720p slowmotion 60fps.
Why S4 with more performance and hardware cannot record in 720p?. Anyone can explain me that??, its possible change the resolution to 720p?
Thanks you!!
It has nothing to do with the CPU nor how many cores it has, it has to do with the camera sensor, i don't think the S4 was ever advertised to be able to record in slow motion.
Then, if sensor feature, but if can record on 60, 120, 240, why cannot record in 720p 60fps at least like moto x sensor.
It possible modify the software to record on 720p??
Thanks you!
in LineageOS 7.1.2, when I use OpenCamera with the Camera2 API. It gives me the option to use 3840x2160 as the video resolution. But when I try to record anything, it says "Serious Camera Error"
So is it possible to record 4K?
Because the ISP (Image Signal Processor) can't encode at 4K due to hardware limitations, following the ISP specification the max resolution that the Snapdragon 617's ISP can record is at 1080p at 60 fps

Ah, Its's good that at least 1080p 60FPS is possible.
I do have one more question though. Why is the Camera2 API so buggy with this chipset? Most of the photos I take with OpenCamera with the Camera2 API enabled is mostly just solid green or sometimes the actual photo. Then after at least 1 minute and 30 seconds the entire phone stutters and just crashes the camera.

Hi guys a question me and my bro have the galaxy s8 he has the plus version and I have standard.
We done a test both of us went onto YouTube went to same channel which was 4k ultra fhd with hdr when we went onto settings on his s8+ He could do 1440p HDR on my standard s8 it could oonly do 1080p HDR anyone why?
check what resolution you have set in your settings

It maybe something to do with what resolution you have your screen set to, by default the s8 and s8 plus are set to fullhd+

Good shout didn't think about that strange thou when using chrome i can run 4k power saving mode on also there i can change it to 8k as well but video won't play
I have a question how is it got along with google pixel HDR support?
Isn't it hardware limitation?

I saw it mentioned in a review, but I don't see a reason this should happen. I know this phone model vs the Mi 9 or the 9T Pro doesn't support 4K @60fps due to CPU capabilities, and for costs' sake the coupled image sensor is also a similar version which nominally identical to the Mi 9's sensor other than not supporting 4K @60fps (lower bandwidth on the image sensor's processor?). The 1080p resolution is also nominally a bit truncated due to this, with 240fps slow motion only being supported at 720fps (and 1080p going up to only 120fps), but I don't understand what's up with the pixelated quality?
With 1080p @30fps, there is no such pixelation, and zooming in even x5 keeps a pretty decent quality with no such rough pixelation. I'm not sure if the phone knows how to adjust the number of pixels used out of the entire sensor while digitally zooming instead of stretching the rendered image, but even if it's only digital crop-and-stretch, at 30fps it at the very least uses a decent filter that smoothes square pixelation.
I can see when using 60fps that the image view is slightly zoomed in, meaning it probably uses a bit less pixels out of the entire available sensor, but it's a very small difference which doesn't match the severity of the actual effect, and again — it doesn't even try to smooth the pixelation. At 120fps the pixelation is even worse.
I suppose having a higher possible bottleneck might secure more consistent performance at lower settings (so perhaps in some aspects you could expect a phone rated to capture at up to 1080p @240fps to perform better at 60fps than a phone only rated to capture at up to 1080fps @120fps), but what's going on in this case doesn't seem reasonable.
So what's your take on this? Should this issue be fixable through software update?

There's no need for a full video, even. Here are a few screenshots from recorded videos in different settings:
At 30fps, no zoom:
https://i.ibb.co/XjmqxHr/FHD30fps.png
At 30fps with X5 zoom:
https://i.ibb.co/yd6pMBs/FHD30fps-Zoom-X5.png
At 60fps, no zoom. Here you can already see some blocky pixelation along fine lines if you pay attention:
https://i.ibb.co/pL6PTkc/FHD60fps.png
At 60fps with X3 zoom. As you can see it doesn't even try to filter the upscaling, so you just end up with blocks of cubic pixels:
https://i.ibb.co/cLNcxzK/FHD60fps-Zoom-X3.png
I can definitely see the pixelation you are talking about, but is it in video itself or the pixelation is because of the video player you are using? Thats why I told you to post the original video.
Also what rom are you using?
same for my device,it has that pixelation on 1080p 60fps recording.
playing it on pc vlc or mpc-hc have it too.
was waiting for someone to create a thread about it. tnx

It is in the video itself. It shows in the camera's "viewfinder" while recording, and then the same way when playing the recorded file. As I said, 120fps is even worse, while it isn't saved at 120fps but at 30fps slow motion in case you thought it's the videoplayer mishandling 60fps playback.
I'm using the official MIUI it came with.

As I mentioned, I already saw something said about this in a review, but I don't see a reason why it should perform this bad with anything above 1080p 30fps. Because the digital zoom on 30fps remains fairly detailed even at around X3, I wonder if the sensor knows how to limit the area of pixels from the sensor used before rendering the frame, thus creating a better digital zoom than just cropping and stretching up from the normal amount of pixels being used. The image is slightly zoomed already in 60fps, as I mentioned, but seeing how it just takes the already somewhat pixelated quality and stretches it up exactly as-is in 60fps, it definitely doesn't use any sensor area limitation trickery in that case.

I have tested my own Mi9T and can say the 60fps video suffer from pixelation for sure.
has the same problem on the gcam ports too on 60fps
so i think xiaomi has to do something on the camera firmware
or imx 582 cant handle it mmm idk

This would be quite strange if it's hardware limited to this extent. Both the Snapdragon 730 and the IMX 582 are rated for 4K at 30fps, which in number of pixels per second is equal to 1080p at 120fps (which the phone also features as an option). But if this upper limit is so far from perfectly-handled that even at half the data (1080p at 60fps) it provides Crappy crappy results... Strange. Are there any other phones currently using this sensor, so we can check if there had been similar complaints?
found this it has imx 582 mi a3 with pixelation

That's quite strange and annoying. The SD 730 is better than the SD 665, so if it happens on both we know it's more likely related to the image sensor itself. But it seems unlikely a sensor released with specifications allowing it to capture up to 120fps at 1080p would perform this badly at 60fps. It looks as if if just takes a 720p 60fps feed and upscales it (without any scaling filters) to 1080p. Maybe it's indeed an issue with how Xiaomi implemented this sensor in software? Both phones we have as examples are from the same manufacturer, so a third party phone could be a better indicator.

Would you be so kind and tell me more in how you managed to make 1080p/60fps work on Gcam?
USing my Gcam port, the app instantly crashes when trying to use the 60fps mod....everything else works just fine.
USing Ornyx05 - 0709 port.

Could you shoot an example of 1080p at 60fps, perhaps use x2 zoom as it shows the issue much more clearly on my phone, and then upload the example? Or just a screenshot of a frame.
So, months have passed and I wonder....do we have a conclusion/reason why the 1080p 60fps videos are still pixelated/jagged when zooming in even a little bid?
For the love of me i cant find anything on that matter anywhere on the web.
Is there a workaround? is it just the camera sensor? software? something else?
Still alive?
It seems to be specific to IMX582 sensors.
My POCO X3 Pro has exact same problem.
I have created an HLSL shader program to mitigate this, and it works well on MPC-HC.
I hope someone would port it to Gcam to do it in real time.
For comparison, added the stock image and one halfed then doubled.
Just for information.
This pixelation occurs also on Huawei Mate 9.
So, my thought is that may be caused by skipped scan lines to achieve 60 fps and poor interpolation for malformed Bayer array (see the attachment picture).
Considering that, I updated my HLSL shader to re-decode the array.
It should not be a perfect solution because there is theoretical restriction by non-uniformity of its subpixels.
I still looking for some way to apply the shader directly to raw pixels before encoding to H.264/H.265 in camera apps.
