Dark video recording on 4.4.2 possible fix

Hello!
As many of you have noticed, after updating to 4.4.1 and 4.4.2, a recorded video with stock camera is a lot darker than it was on 4.4. It was done probably to increase framerate at night, but crippled low-light video capability. I have noticed that Camera MX by MAGIX allows recording video with lower framerate in low light, but a lot brighter, almost like it was on 4.4, and in full HD resolution.
Below are two samples
Notice higher framerate but darker image.
Notice lower framerate but brighter image.

Nice find, the 4.4.2 update made the video recording in low light unusable for me really , way to dark

It may be your camera device problem. you can go your servicing center and fix it.

Definitely not a camera sensor issue, since I know and have seen how MY nexus 5 stock camera shot video in low light on 4.4 and how badly it does now on 4.4.2. I reverted back to 4.4 and video in low light is brighter.
There's another repeatable glitch. When switching to Panorama mode in stock camera (not photosphere, panorama) and then to Video recording mode, the image in the viewfinder becomes brighter and stretched, and when you press Record, it reverts to dark video.

Same thing I noticed.
The camera software needs a fix,so as immersive mode bugs.

4k 60fps camera flickering.

I've had the phone for a few days now and overall I'm very pleased with it yet I have one issue. The camera when recording at 60fps at any resolution has crazy flicker. I can record at any resolution at 30fps and it's fine.
I've tried other camera apps on the store but none seem to be able to record at 60fps, open camera for example, won't record at 60fps even when I set it, just records at 30fps.
I'm using the latest eu rom with included camera.
Would appreciate some help, thanks.

Might be an issue with the sensor on your phone. I don't have any flicker with any setting at 4K 60fps.

I just tested my camera - it has no flickering with [email protected]
Whatever modifications that you have made to your phone must be responsible.

I think you're probably correct. Tried it again today and it's working beautifully, I've made no changes or installed anything since yesterday.
Only setting I've disabled since testing was deep process clean, re enabled this to test and it's still working.
Hopefully it will remain working, hard to go back to 30fps video after seeing 4k 60fps.

Ok, so I'm able to replicate the problem.
It's a certain light bulb in my living room that's causing this, it's a 72led corn cob low wattage bulb. Only occurs in low natural light.
Went all through the house at night with the lights on as well as the front and rear gardens and no flicker, only occurs if I have that specific light turned on during the evening in my living room, how odd!
To the naked eye this bulb does not flicker but for some reason makes the phone camera go nuts.
I'll have to check the Hz rating of the bulb.

Video stabilization issues

Hi, i am having the strange issue with video stabilization on my note 9. It started after receiving one of the software updates. The issue is that on certain video resolutions (for me it started on 1920x1080 and 2224x1080 at 30fps) video is cropped and zoomed in as you would expect but the saved video is still shaky. Funny thing is - when i installed Android 10 the issue didn't go away but instead note stabilization doesn't work on 4k and works on 1080 now. I have no idea what's going on and the service center charged me $160 to fix it, but that's quite a lot.
Has anybody faced anything similar?
Can someone please check on your phones if shooting in different resolutions with stabilizer turned on results in different stabilization effect?

Question Slow motion bug(solved)

Hi, when I use the slow motion , the whole display starts to flicker, but still works. all the other camera modes are fine.
Is that software issue?

The display is flickering while recording, or the video when playing back? I just tried, I don't see any flickering while recording. But if it's in the recorded video, what kind of lighting are you in? I recently tried to take a slo-mo with my S20, and had significant flashing. It was at night, I figured it was due to the LED lighting flash rate being slowed down.

Yes, i would suspect this. Unbeknownst to the average person, LED lights tend to flicker A LOT. They do this at a given harmonic of the line frequency. If you're in the US then the LED will flicker either at 60Hz or 120Hz. Most people can't see this at full speed as the light has a bit of persistence and we're geared to see smooth motion. But, when you slow it down you find that at 240Hz or 480Hz the video is now fast enough to catch the dark patches in between the pulses. So, the video seems to strobe. Not all LED bulbs will do this and those that do won't all do it the same. But, it's there, you just can't see it. Keep in mind when shooting video in other modes this could still happen. At 60Hz or 120Hz video even though it's full speed you are still potentially capturing some frames in between pulses. This could cause a sort of beat frequency to appear. So, if anyone is having that problem when trying to shoot video your options are 1: do it in the sunlight. The sun doesn't flicker. or 2. Get a constant light source. Fluorescent bulbs have greater persistence as do the old incandescent bulbs. Professional lighting will be consistent too. But, $4 LED bulbs are going to SUUUUCK for slow mo video.

Yes. You were right. The problem was the led bulb.
That was interesting.
Thanks guys

White Lines in screen when play online video S20FE

I suffer from white lines appearing on the screen when playing an online video in different places every two minutes and this problem occurs only at 120hz and adaptive brightness is on, but when the adaptive brightness is off, this problem does not occur, does anyone suffer from this problem and it also does not happen if The screen frequency was 60Hz, does anyone have this problem and what is the solution, thank you

no offence but your photos are extremely low quality, if there's an issue no-one could tell.

Like this photo

I see the same thing.
It flashes only one frame, I assume, but could be 2 or 3 frames.
For me it can be two white lines near the top, or one line more to the bottom.
I see it on YouTube and Netflix...

It is probably "low quality" because he had to use "slow motion mode" or a high framerate camera to catch the line flash... It is a really fast flash of a white line, about 1mm wide, across the screen.
