I'm getting some seriously nasty bars during slow motion recording (I attached a screen shot which isn't as bad but when it's a video the bars move all around and are very distracting) Anyone seeing the same thing or am I looking at a defective phone? I already swapped out phones yesterday due to a stuck pixel, but best buy has been very easy about it thus far. Just wanting to see if this is hardware or software, thanks!
Yep, exactly the same here. Gets worse the more the sensor gain ramps up.

Checked the sprint store demo and a best buy demo, All the same. Must be a low light issue. Oh well, Guess most of the time the feature will be used in the daylight (although this may be a bad thing when trying to slow mo some epic beer pong matches)

Figures, seems like it would be a hardware issue, but maybe there will be some magic firmware update that will help.
Most serious hd cameras require a lot of light, so this should be no surprise when recording show motion videos. Just be sure to have adequate lighting in the future

I haven't looked closely at the example yet otherwise I would have put my 2 cents in earlier.
I work a lot with cameras and know them very well. One thing to keep in mind is cmos sensors don't expose every pixel at the same time. This causes what is known as the jello effect when you move quickly left and right. This can also cause what is known as rolling shutter. I believe this is caused by the shutter speed in combination with the way cmos sensors work. When I get back from this weekend trip, I'll see what is going on.
At work I have a professional Sony video camera with a backlit cmos sensor. If I drop the shutter speed down too low to help when it's too dark, especially around fluorescent lights, I get brown bars rolling across the image. It's just a physical limitation of the sensor no matter the camera. Some hide it better than others. I hope this helps clear this up.

This is nothing like traditional noise caused by high sensor gain in low light. We're talking dense horizontal lines only in slow motion recording, which I'm guessing is 120fps? 60 fps mode works fine. I've seen examples of slow motion video recorded by the euro version in low light that didn't have this problem.

That doesn't eliminate it as a cause. The example you saw could have been in better lighting conditions than you thought, or the euro edition might have had older firmware that didn't let the ISO go as high (thus, the whole image would appear much darker, but less noise).
120fps slow motion means the camera has to use at least 120th of a second for a shutter speed. This is relatively fast for a smartphone camera, so it has to bump up the ISO to compensate. If the light is especially low, it will have to move all the way to the upper bounds of its ISO capability to get a usable image. Meanwhile, a 60fps video will have MUCH more time (2x is a lot of time) to grab light, and so it doesn't need to force the ISO so high.
It's extremely unlikely that a firmware update will solve this issue. All they could do is just force the camera not to use that high ISO setting, resulting in slow motion videos that are too dark instead of too noisy.
(Also, BTW, this has nothing to do with the jello effect)
How do you do slow motion video recording? When I have the video camera on, there aren't any menu options available.

Thanks for adding. I hadn't had a chance to even look at the example posted but felt like it should be addressed by someone. I'm out in the middle of nowhere right now, video streaming isn't always going to work well here.

The euro demo was in CONSIDERABLY worse lighting, without question. I don't have time to look for it now, but it's on Youtube.
The Euro version just got an official update regarding several problems. It also included a low light slomotion video upgrade

I'm getting a stuck blue pixel when taking photos in low light... is anyone else experiencing this? The blue pixel is showing up in the actual photo taken, so I'm assuming it's a problem with the sensor.
Daylight photos aren't exhibiting this behavior.
Anyone know what if there's been any progress to getting this set up on our devices? This is literally the only thing I feel like it is missing. And I really don't understand why it is so hard to implement if the camera has the capability. Maybe Im missing something. Really wish one of the dev's here could get this set up for us all.
Thanks!
Really surprised no one else is really interested in slow mo video.
look in your app store, there are apps for slow motion recording, just not many. oh, and the devs here on xda, do things for free, no body pays them. if i were to make an app for slow motion video, id want to get oaid for it, i wouldnt do it for free. it actually would take wuite some personal time to make.

He means apps that shoot in 120-210fps. Not apps that shoot 30fps and cut that down to 15 or less and render the poor mans slow mo.
In regards to OP. No, not yet.
No camera on the planet can CAPTURE in slow motion. To do so would require travelling away from the scene being captured at insanely high rates of speed, specifically, to turn the capture speed down to 50% would require the capture device to travel away from the scene at HALF THE SPEED OF LIGHT!
ALL "slow motion" video is slowed down during PLAYBACK. It is done by rendering the frames at a rate lower than they were captured. Now naturally, the higher the rate they were captured at, the more smooth the playback will appear once they are rendered at a lower rate, but the actual function is identical.
This would require the camera to be able to capture video at 120-210 FPS... which ain't happening.

uhmmm the N5 camera was able to do 120fps and so is my old s4, the camera in the n6 is perfectly capable of it hardware wise.
+1 for looking for slow motion
Well, as allready said this will not come until Google implements it or something magical happens
This is the closest I've found:
https://github.com/PkmX/lcamera/issues/153
Seems it theoretically could be possible to do the same hack as on nexus 5 for higher framerate videorecording. So keep the hope alive! I think i might reconsider going for nexus the next time around if google keep on skipping this... Oh well.
Lcamera - linked above is the best camera for now for taking really low light photos at least. I can take pictures at half a second exposure :good:
So here's hoping 120fps for the n6 will show up too
Am I the only one who is experiencing laggy zoom both in and out?
Rear camera is jumping from 1.0x to 1.2x, 1.4x etc. creating a laggy experience.
It's not a big deal while taking pictures, but if you are recording you can actually see that your footage is totally destroyed if you zoomed in while recording.
With front camera it's a little bit better, but it's only since it goes from 1.0x to 1.1x, 1.2x, 1.3x, it's still lacking some kind of animation to smooth it out.
Did I get a poor unit of Huawei P20 Pro or is it like this for everyone?
Also do someone know if Huawei is planning to fix it? Since return policy is valid for 14 days, if they won't fix that I am gonna return the phone.

I wouldn't call the zoom laggy, and I think they have done it this way so you can achieve your desired zoom level faster rather than have it smoothed out and be slow. You could probably download a camera app from the Playstore which would do the smooth zooming though.
Snapchat has the same problem. The zoom is laggy
It's because it's changing the camera to the telephoto lens from your regular lens. The third lens is just a monochrome lens.
Apparently this problem is fixed in the beta
Me too
I currently have this problem too. Instagram, Snapchat and even the official camera app zoom looks laggy and slow. Currently using firmware version 8.1.0.133
The same on 8.1.0.154. Is it possible to turn off all lenses excepting one which you want to use? I think it could fix the problem with zooming.

This is the feature that we all wanted and have the ability to shoot raw on the lenses individually I think but i dont know if Huawei is doing something about it
I just noticed today that my Huawei P20 Pro camera flickers and there's a wave-like flowing on the screen when using Super Slow-mo at x32 and x8 under fluorescent lighting, like in the office. I have yet to try under daylight.

Hiya
This is normal. Slow motion recording especially at the higher fps needs really good light as in outdoors.
A lot of cameras flicker indoors.
Nothing wrong with your phone though, my S9+ was not good at slow mo indoors either.
Because the lights are flickering.

That's the problem... You can't record super slow video under lights (not only p20 pro but with every phone) because of the flickering of lights that your eyes can't see... If you try in phisical light you will see that everything is good...

Maybe you must read better the thread. It's only a point of view or at best a theory.
Although I agree that it does not have the best recording in slow motion
When the winds of change blow, some build walls, others build windmills
It's on high-speed cams, they have tested a number of phone cameras, they say the p20 pro is recording at a slower speed than 960 FPS and is using software to slow it down even more.

The problem is just that your light is flickering.
If, like mine, your light flickers at 50hz, then 960 fps will exhibit worse flickering.

Yes, I had already read it but as I said it is just an opinion (that even maybe influenced by another manufacturer...)

This mostly happens with Exynos series of phones. Although some improvements have been made since the first update, camera still fails considerably. Noise and frame drops are something which is unacceptable. We just have to create more noise for Samsung to notice and work on an update. I don't think this phone is what they said it is.
We just have to wait for next update. No wonder samsung s20 ultra scored better than S21 Ultra in camera ratings.

Yep, definitely related to the Exynos phones. I haven't had any issues with my camera app using any of the different settings or modes available. But I do have the SD888 version of the phone...

Drives me mad that there's two different versions of the phone that cause performance issues. Why not just put SD in them all or make their own chip work?!

Agreed. Luckily enough, just after they had released this phone, they had admitted to their current chip having a few issues due to their manufacturing process and that their next generation Exynos chip won't have such issues anymore... So if we're lucky, that'll be in the S23 Ultra.

That anything below 4k is crap thing depends on what lens/camera you are using, 1080p 30fps is the only remotely usable one on the exynos version in low light if you are using wide angle lens. Check this out:

I have tested this phone camera rigorously. I don't think 1080p works good in either lens or mode. Slow motion and super slow motion should be removed because its useless. 4k 60 Fps is the only stable video we can take on this phone.

I have Exyons version. The slow motion is so smooth and there is no frame drop.
However the quality is crap in slow motion and tbh the whole video recording is not that good and has noise.
Portait video is good.

Yes, the recording quality is of no use. Especially if there's lowlight it's almost useless. Hyperlapse also has significant noise. I don't understand if people who are saying the quality is good actually get better videos or they are coming from a previous gen phone which was even worst.
No offense to anyone. But I am just so unhappy with this phone after having paid so much and Samsung portraying the phone as a beast. Its still a kitty cat.
If you have frame drops and etc, consider updating to the latest firmware. If your phone still does it after the latest firmware, then it must be deffective and you have to return it ASAP.
Additionally, I have noticed that if you turn off the Image Stabilization in the camera settings under video options, the whole noise thing becomes much better for normal recording. While it still seems to be somehow stabilizing :O
P.S. I do not mean only the supersteady option. Both have to be OFF. Please test it and share your feedback here so if it works, others can benefit from this as well.
