Low light camera performance and framerate on ROMs - OnePlus 3T Questions & Answers

I love how the stock ROM will not drop frames in low light, at both 30 and 60fps. Also, OOS allows all 3rd party camera apps to also remain at a steady 30fps. Have ROMs been able to achieve this level of performance yet? I'm looking for video/screen record samples so I can check before flashing (or returning the phone).

[Q] Camera flash output / brightness in ICS

Is there a way to modify / lower camera flash brightness (output) in ICS?
When taking photos in darker environment, flash 'burns' the photo i.e. colors are washed out and photo is overexposed. I also noticed when the flash is activated during focusing, its brightness is normal.
As far as I remember, this was not the case in GB based ROMs (in which I always used ported stock LG camera app).
I've yet to try out alternative camera apps (zoom fx, ucam...), but I'd like to stick to the stock LG software.
TIA
same problem here,but i used Jbcamera+ for taking pictures (it has great autofocus and the flash is ok) and camerazoomfx for video recording,(the stock one not focusing and the jbcamera+) because the stock camera is bit annoying for me
I havent used the lg stock camera but as you have said the photos are over exposed when using flash so isnt there an option to decrease the exposure? I use the 4.2 Camera and when taking night shots depending on how close the target I set exposure to -1/-2 and get decent low light shots, flash wise that is.
Well, there is exposure compensation on stock camera app, just haven't thought of that before. Will try tonight both camera JB from play store and LG's app with exp -1 and -2.
Thanks.

I thought camerazoom fx only took photos?
Yes, the exposure is way too high. Generally the photos are affected by the flash burns. The only solution i found was to decrease the exposure to -1 or -2.
OK, much better with exposure at -1 and -2 (depending on the surrounding light level).
I just wish LG camera app were a bit more 'intelligent' to figure exposure compensation on its own, but then again it would probably have to rely on some DSLR-like metering methods that would certainly double the size of camera/CCD (and the bulge where it sits) as well as its price...
If this were top priority to me, I'd probably be carrying a 'stupidphone' with an enormous camera at its back (nokia 808, anyone

i9000 media_profiles.xml CM10.1 framerate reduction for brighter videos in the dark

Hi, I want to create another profile in media_profiles.xml (or edit existing one, 480p for example)for recording in dark environment.
I succesfully changed audio and video quality, but I can't decrease framerate for brighter videos (camera FCor I can't press record button). I know, that is possible - http://forum.xda-developers.com/showthread.php?t=1583259 (yes yes, stock rom and another variation od i9000 series, but this mod is based on the same thing as I wrote - brighter videos by lowering framerate .. and it works - I had this phone before)
quote:
If you limit the framerate to a minimum of 30fps, the video can become very dark when there is not enough light. If you lower this limit to - say - 10 fps, the video will be brighter in low light, but it will be "laggy" and because each frame is exposed longer than at 30 fps, blur will be more likely. Both is inevitable, but in my opinion still better than a black video
I will be grateful for any help, it is really important for me, because I often organizing a underground parties,
and I want to promote it, so I'm doing a video report from them and... audio quality is superb (better than S3 or S4!),
but (as I said - underground parties) it is dark, there is only a strobe, small light for artists and nothing else, so ... almost nothing can be seen on my recordings

Changing camera auto-exposure?

So as we all know, the Nexus 6 camera sucks in low light compared to just about every other phone on the market. I played with L Camera (camera app that uses Lollipop's new camera API's) and played with the exposure and ISO settings and was able to get very good quality pictures with minimal noise. This makes me believe that the hardware is capable of alot better low-light performance, but on the software side of things, the "default" auto-exposure setting is set too low. Is there any way to change this?
I'm able to get okay results using HDR+, but on apps like Snapchat where there is no control over anything, low-light pics are abysmal.

Recording with constant framerate (LOS)

Hey guys!
I'm currently using nvertigo67's LAS for the 1+3T, which comes with OOS camera pre-installed.
It works extremely nice, except for one thing. It does record 1080p in 60fps, however with a variable framerate. I asked the dev. if he knew any way to change it to record at a constant 60fps, to which he said he doesn't know much about changing codec settings (post 1 & 2)
Do any of you know what I should try to do to be able to record with a constant framerate?

use a camera app where you can lock the ambient brightness like open camera. then try to lower the ambient brightness shown in the camera by holding the camera to a bright spot and press on the lock. this changes the iso so the framerate rises and by locking it it will stay on that framerate constantly. ofc you can also use a camera app where you can choose between different iso values.
but for me oss camera has allways same framerate no matter what light conditions. your issue might be kernel related. low performance maybe. or some apps consuming cpu in the background

I have tried Open Camera, unfortunately it doesn't go above 30 fps, even when selecting 60 as the approximate frame rate.
The developer told me it's how the encoder works (please see "post 1 & 2" I have linked in my first post, he explains it there pretty well.)
OOS camera worked for me well too, while I was actually using OOS. The AOSP camera doesn't support 60fps recording either.

Question 4k 120fps slow motion broken

This mode a year ago used to record and payback at normal speed to the left and the right of the sliders then you adjust the sliders to change the slow motion section in the middle. Now when I use this mode, the sliders adjust the section where it plays normal in the middle and the sections to the left and right of the sliders plays at a super fast speed. How can I get it back to the regular slow motion like before? I cannot find anything about this problem anywhere searching the Internet.
I can't see that option on my device?
Seems that there is some info on the internet but it refers to a OnePlus 9 not the 10, they reference changing the speed using software after you've recorded it.

I see what you mean now, so yes you do have 4K 120fps but it's not standard slow motion.. it's just normal video at a higher FPS rate so it's smoother.
You could adjust the playback speed and watch it in slow motion so 30fps and it'll appear slower but not sure what options you'd have in that case.
