I'm gonna purchase this phone but need to know if you can zoom during video recording?
At basic 4K30 setting does it switch cameras/lenses when you use the zoom slider?
Short answer is: nope.
At 4K30, with the standard camera app, you can select one of three lenses: ultra wide (0.5x), standard (1x) or the zoom lens (5x). With each your then have the option to digitally zoom in during filming, with the ultra wide then ranging from 0.5 to 2x, with the standard going from 1x to 6x and with the zoom lens you start at 5x and can zoom in to 15x zoom max. A slider will be on screen to help you with that. It's all digital zoom, so don't expect picture quality to remain the same.

This is bummer... Is it down to Xiaomi or it's the first phone with multiple cameras that can't switch on the fly during video recording ?!
OK that person is wrong. I zoom while recording all the time... I usually either use 720p to minimize file size or 4k60 for max quality. Maybe he's using the wrong mode.
My personal experience is exactly what Appelsap described. No way for me to switch cameras on the fly while recording video.
What about other apps like FIlmic PRO - do you have access to the other cameras?
In Filmic Pro I could only find the switch from back to front. Is there another way to access the other cameras?
So you can zoom, but only digitally using the same lens. You can't switch lenses to zoom even more during filming. I tested the 4K30 as was asked, didn't try other formats (720p/HD/8K) but expect the same result even then. Main issue would be that switching lenses would be noticable in the resulting film. The lenses are in a slightly different position on the phone - they have to be next to each other rather than on top of each other , so whilst zooming in or out you'd see the camera shift suddenly to a slightly different position. I doubt other multi-lens phones can switch camera's during filming, you'd notice it then too - but do correct me when I'm wrong and tell me how the software then solves the suddenly shifted perspective (or not).
Every other multicamera phone (as far as I know) is using different cameras (lenses) while video recording. My most current phone is Find X2 Pro and it is using all of the cameras, however they are not enabled in Filmic Pro, in comparison OnePlus 8 PRO is enabled and all cameras can be used in Filmic Pro but this is different topic.
So basically this is first high end camera centric phone that is unusable in video recording, what a shame... I will cancel my purchase then.....
My Find X2 Pro is the best package overall but I'm missing the 2x telephoto camera as there is quite a gap between the 25mm main camera and 130mm 5x periscope one.

It's not only the perspective. Different cameras have different aperture, meaning different exposure. So if you pay attention, you will notice that - it gets darker when the phone switches to 5x camera. Don't know what cameras and aperture have the other phones but I'm extremely interested in an example video zooming from UW all the way to periscope and producing usable picture quality in 4k.
Just wanted to let you know that on latest EU weekly, the switches cameras on fly during video recording 1800p.
I also confirm that the video produced is not the best quality as expected - changing the camera changes the exposure and focus too.
For 4k it doesn't switch cameras.

Just tried it, and you are so right. At 1080p it does switch lenses during zooming (in/out), which is very noticable in the result, so why you'd want that is beyond me really. But it is possible. I'd like to see another phone do this without changes to exposure and focus, that seems very unlikely to me.

I'm trying to understand what makes a camera phone produce good quality pictures. Initially, I thought it was pretty much solely dependent on the camera itself: I have an HTC EVO 4G LTE and it's 8MP. I want even better picture quality so I was searching for phones that had more megapixels, since I assumed that more MP the better. But during my search, I saw more discussions centering around the camera software, and how that effects pictures, which I hadn't even known before. Can I just simply download a camera app and get better quality pictures, or will I have to get a new phone, or both?

Sort of. Megapixels are a measure of resolution, which is essentially how many mini-dots of color make up an image. One megapixel is the equivalent of 1,000,000 of those little dots, called pixels. They make up every digital screen you've ever seen. The more pixels an image has, the more detailed, and the the clearer it can be.
Now, there are some issues with large amounts of pixels in a small camera. One is that each pixel in the sensor must capture light, and the smaller they are, the longer they take to capture enough light for a well-lit, clear picture. That leads to the second main issue, which is blur. When the shutter time (amount of time that the camera sensor takes in the light that forms the picture) is long, you get a well lit, clear picture... provided the subject is stable, and your hand is too. If something moves, then the sensors see it both in it's initial - "true" - position, and every position in between where it ends up when your sensors stop taking in light. This causes blur. When the shutter time is short, blur is reduced, but pictures are darker.
So, yeah, the software you use is important. Some will use smart software to correct for blur, some will automatically brighten the image (Which reduces detail), and the best ones (IMO) let you set your own shutter time depending on what you're taking a picture of. For example, if you're watching a baseball game outside, you should set a very short shutter speed so that you minimize the amount of motion blur captured, but there should be plenty of natural light provided by the sun. If you're in a dim art gallery, you may want a longer shutter time, as you need the time for lighting, and nothing's going to be moving.

Wow, thank you for that very detailed answer Creed I understand this much better. So basically (let me know if I'm wrong here) a large number of MP won't make much of a difference if your software and settings suck? So, on average, what is a decent amount of MP? I have 8 right now on my HTC EVO 4G LTE. Can you also suggest a good camera app? Thanks very much in advance :good:
As we have received Nokia 8 PRO Cam update globally, some of us not happy with the final application.
There are lots of bug with this new pro app and it is so clear that it had been rushed out to silence us.
Firstly, in landscape mode in order to launch Nokia 8 PRO features you have to go trough settings, swipe up does not work which is ridiculous and it shows they have released the PRO app without real user feedback, only dump software engineers can not notice such bugs.
Secondly, in default settings shutter control is on which makes a lot of noise in dark situations, try to turn it off and you will see much much better result with less noise. It is not a miracle, does not reach the level gcam has achieved but at least , with PRO cam we see less noise.
Considering it's price, I do not except a miracle from Nokia 8, but this little details kills Nokia legacy. I believe, they should listen feedback from users first before they launch any update.
..please? You have no clue how cameras work? You can't beat the physics. It's all about the amount of light being captured by the sensor. Dark situations will always be hard for small cameras, and vice versa crap cameras, can perform well in bright situations if the lens is sharp.
With a faster shutter will have few options to make to even out the exposure:
Open up the lens aperture more. (These small lenses are usually fully open always if not used in bright sunlight, so there is nothing to gain).
Raise the ISO. This is basically amplifying the sensor data, resulting in a brighter image but with increased noise and loss of details. This is what you are complaing about.
Revert back to a lower the shutter speed so more light can be collected. The disadvantage is that you need to hold you camera more still and moving objects will still not be frozen.
Give up and lower the exposure resulting in a darker image. (Exposure compensation)
A fift option is also cheating, adding post process noise reduction, think a bit like anti-aliasing resulting in even more detail loss. Personally I'll take a slightly noisy image any day in favor of a software drawn oil painting without details.
I can't comment the bug, I haven't hit it. I'd rather the Camera app to remember the settings from last session and also some user programmable "presets" would be nice. Or a full Live Bokeh from a short-cut would also work as an work-around just to make an example.
Usually your subject is gone before your camera settings are in place.
Anyway, t best solution for you would be to get a larger sensor and a larger lens so more light can be collected. Seriously, for example a Sony RX1R II would easily beat any cell phone camera out there in lower light.
Has anyone else experienced a slow shutter when hdr and/or ai are enabled?
If your taking a photo of a moving object like a dog, the camera takes a second before the shutter goes and the picture is blurry or you miss the shot.
It's like the camera has to think too much before it snaps the shot. When I turn these option off I find the camera very quick and responsive.
The same happens to me ..
Ultrawide 60 fps video recording!!
So I've had this feature on P30 pro and always wondered why Samsung never had it...until I stumbled in the settings in Gcam....and it worked!!!
I basically had the Gcam version 7.3.018 , enabled ultrawide lens (it's telephoto option for some reason)
Chose 60 fps and it worked!!
I'm recording ultrawide in 60fps from Gcam....and the chip is more than capable, barely any dropped frames in artificial lighting.
Anyone know how to somehow enable this in stock cam?
How do I enable telephoto or wide angle mode for video on gcam? I'm using 7.4.104. The 5.2 beta. Not seeing any option

On 7.3.018 (not sure about other builds), you need to go into Options then look for Advanced. You'll see an option for Auxiliary Camera. That's where you can toggle the telephoto and wide angle lenses.
IMPORTANT NOTE: Once you enable Telephoto (it shows up as the 2x zoom button on the Video screen), you MUST select it BEFORE changing the FPS to 60, and you MUST change the FPS to anything LESS THAN 60 before moving back to anything less than 2x zoom. I have no idea why it 60FPS isn't supported by the default back camera, but it's apparently not (at least not in GCam.)
If you screw up and change to 1x or 1.5x while still in 60FPS, you WILL have to (at a minimum) reboot your phone to get any camera-related apps to work again. You possibly will have to clear your GCam cache, and possibly even your GCam data (I defaulted to just clearing the app data as a whole when doing my testing, and I know it works after a reboot if you clear the data, but it may be possible to just clear cache and reboot.)
Happy filming,

My way around it is simply leaving it at constant 60 FPS, and never entering the video mode. I just choose which len I wwant from the main camera, and then keep pressing the shutter button (which just goes into video recording mode). Not too convenient, but avoids the hassle of remembering the lens and getting the camera frozen.
Hi
While making a video of close objects Whenever the system shifts to zoom lens the saturation increases and colors become over saturated.
I make videos of gems and stones. and for that purpose i bought this camera.
Especially the blue stones become too blue when i zoom in and zoom lens turns on.
Is there a way where we can select individual lens manually so that the zoom lens doesn't turn on unless I want it.
Try with turned of AI. If nothing changes after that I don't know what can you do.
When the device switching between camera modules maybe is normal to have problems with saturation. All three camera modules have different apertures and they receive a different amount of light.
The only solution that I found is by using the pro mode and setting the white balance manually when the zoom lens turns on. By doing that the camera keeps the selected saturation even when the lens gets changed.
This is what I think. Need to confirm it with different color items.
You guyz check it aswell.
I hope mate 40 doest have the same problem. Quite disappointing bug considering the price of the phone and camera quality.
