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.

Hello,
do you have any idea if the front facing camera is limited to like 15fps?
I was testing google talk video and I noticed that the back camera is much smoother than the front one when calling.
So i thought i was a limitation of Gtalk but when I tried to make a video in "camera" the fps is the same.
EDIT: I tried to see details of the recording. It shows 7fps!!
WTH? is this a hw or sw limitation?
I think software related
just the way some devs have changed some lines to record on higher frame rates
i gues they can do the same with the front cam
Does it happen with the stock ROM? If yes this a very stupid limitation. Why in 2011 would they do a 7fps camera?
I'm using cynogen

To minimize traffic/save money on a cellular network. This needs to work on even the slowest of connections.
That being said, there definitely should be some auto-detection/settings which should control the framerate.
I tried to make a video call wiht an iphone 4 with tango. The iphone was "smooth" and watchable. The lg stream was upside down, choppy and very low res.
Just checked an FFC recorded vid in MediaInfo, it's 640x480 @ 30fps

So how's possible?
Even if the mediainfo info was wrong I can assure is nowhere near the 20 fps range

I think I got what's happening.
The driver (?) changes the frame rate according to the light available. I don't know if you're familiar with how photography/lenses work. I do so I'll explain.
Normally a very small sensor (like this) would have a very low sensitivity so to get more light into the sensor it would reduce the shutter speed to like 1/5s and clearly below.
The strange thing is that it also reduced the framerate but the visual result is practically the same. In fact if you find a very strong light position(sun light basically) you will get 30fps.
I don't really like this behavior, I think I prefer a smooth recording with low light (solution would be to turn the lights on ) than 7fps with auto light obtained with low shutter speed.
Do you have specs about the sensor size of both the front and back cameras?
Yesterday I tried to make a video call with Tango with an iphone4 and o2x (both with me) and the iphone4 in the same light conditions sent a noticeable smoother and cleaner video.
What I'd like to know is if the o2x has a VERY small sensor OR if this is a bug with cm7, since they have plenty of problems with the cameras drivers due to nvidia source code missing. Or if this is just how the driver works
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

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.
Outside (the house), cameras works great, quality is good and about 12mbps bit-rate and 30 fps, inside however cameras lag like hell, record at 10 fps 4mbps (bit-rate drop of course related to fps drop). I think it has do do with lighting, inside a room it records at 10fps but if I point camera at a light bulb it goes to 30 fps and records smoothly.
So seems like a lot of video noise is generated when filming in dark and hardware can't keep up. Are you tablets the same? is there anything that can fix this? It's on FireOS 5.1.1.
edit: Ok, I see from this video that this is expected from this tablet. But not sure about the reason, maybe it has to do with not enough light reaching the sensor for 30fps? I have no idea what I'm talking about though. Is there any software way to increase FPS in the dark?
P.S the camera app is so bad without any options.

Every device with a camera I have ever owned works like this, including film cameras since they were invented. Less light = longer exposure, everything else being equal.
For some reason I get some kind of severe lag when recording video, especially noticable during camera movements but it's there all the time. You also hear the chops in the sound. The problem is worst in 1080p, it's a bit better in 4k. 1080 gets the choppy lags in all 3rd party apps I've tried as well as in the stock app, very frustrating. Changing the bitrate doesn't seem to affect this issue much, it's doesn't get less choppy at lower or higher bitrates (in Open Camera).
Video stabilization and noise reduction and stuff like that is turned off across the board as far as it's possible since I use a gimbal and do all processing in post. And yes the video is choppy with or without the gimbal, it makes no difference for that.
At first I thought it had to to with bad support for the 3rd party apps I use but then I realized the problem is just as bad or worse in the Huawei photo app, which of course produces bad video quality in the first place but that's another issue.
Recording in slow motion on the other hand works fine, cranking up the bitrate to the max and recording in 120fps in open camera with manual focus produces the best slo-mo quality 1080 footage I've seen a phone do so far. So I know for a fact that the phone can produce good quality 1080p footage, I just can't make it work with normal frame rates for some reason.
Anyone else had this problem? Is my phone simply malfunctioning or did I do something wrong? I'm on the 131 firmware version, firmware finder also lists the 131a as compatible, could that solve the issue?
Any help appreciated.

I have this issue in 60fps
When I revert back to full stock it's fluid and works as expected.
Once I've rooted and installed twrp etc plus a few apps it starts to get laggy, I don't use 4K so don't care..30fps 1080p is what I use most and it's perfect..just annoying that 60fps doesn't work as it should..really annoying.
At total stock it should be fine.
I also use a magisk module called swap torpedo which eliminates the use of a swap file, not sure if that matters or not.
Also I've seen this issue present on all firmwares
In which app do u have this issue?

All apps including Huaweis own.
I've contacted support and they say they'll try to find out what the problem is with my choppy 1080 video.
Obviously that doesn't adress the absurdly low bitrate limits and lack of support for advanced functions in 3rd party apps, which are simply limitations of the p20 pro for now, they said they are aware of those issues as well and looking to fix them.

Ok so may have a fix for this.
I'd previously changed device resolution to HD from FHD changing this back fixes 60fps video, it makes sense that it would offer the same for the other issues you've been having.
Check it out its under Display.
About the laggy video, I just looked into this issue and found something really interesting. When choosing full HD resolution and shooting a video, I find it laggy. But when choosing FHD+ 2160 x 1080 p, the video is amazingly smooth. I suspect that when you choose FHD, the phone is doing some downsampling which causes a huge load on the CPU and makes it laggy while FHD+ does not cause such a big downsampling, because of the 2160 width, which is the native 4k height. Maybe someone who knows more can confirm if what I'm saying is actually true. The kirin 970 does not seem capable of proper processing power like it is advertised.
I have te same issue. FHD 30fps is horribly stuttering, while FHD 60fps or 4K are ok. Do someone found a solution to this? It's incredible that the most powerful and advanced camera phone at the moment have this flaw!

Hey, did anyone find another fix for this? I changed my screen resolution and it makes no difference, still getting laggy and choppy video.
Hi guys,
I have just recorded wedding speeches and the video is choppy as hell at 60fps. The audio is fine but video isn't. Any way I can salvage the clips?
Thanks in advance
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
