Why when recording video at Full HD the angle of view changes ?
The higher the video resolution the narrower the field of view becomes.
Of course the lens is prime so is it using only the center of the sensor ?
thanks
zoom - wide
when recording video at 1080p the lens becomes zoom.
when recording video at low resolutions or just using the camera for photos it becomes wide lens.
have you noticed it ?
A thought I made was that because the lens is prime it crops from the center of the sensor for HD video. But what's the reason to do something like this? Easier CPU processing ?
any thoughts ?
And talking about the video ...
Is there a possibility (mod or app) to record video with the screen off ???
camera noise
I don't know about the screen but I am glad they silence the camera's shutter sound when the phone is at silent mode with the new official update.
There was someone that enabled a no-zoomed mode in the camera app. But that made you lose 720p recording, as he had to change the 720p mode into 1080p "wide" recording. Maybe someone knows what I'm talking about and has the apk for you.
good idea
Why not recording full hd video at wide and zooming in (like the camera does) when ever you want ... maybe because this means that the phone has to capture video at 8 megapixel and then downgrade it at Full HD. So this must be more CPU demanding.
Probably the phone records video at 1920x1080 using the center of the sensor. Capturing only the center of the sensor does the zoom effect. I cant think another reason why loosing the wide angle.
The narrow field of view is useful in some cases (maybe outside) but recording inside rooms everything is very close...

Ok, I wrote also in other threads but haven't been asnwered at all. I have a Snapdragon 435 device from Xiaomi and a high end sensor of the front camera! An OV5675 Omnivision 5 mpx. My problem is devided into two parts. The main part is that I can take extremely high quality pictures with Google Camera, even if the preview image is a very bad one even with camera2api activated, blury and low on framerate ( abou10-12 if high brighness and smoother if I lower the lights of the sensor when simply opening the camera app and not taking pics ) . When it comes to make a video call, in any app like Duo, Whatsapp etc .... The quality of the preview AND of the call is awful! It is vey blury and low fps, just like in the cheap stock camera viewfinder ( preview mode) . I want to understand, is this limited by the software or it is because the hardware is low end?
I will tell you why I am so concerned of this question - When I open the camera app and switch to the video, I get a very cool FPS on the preview ( not when recording, just the preview viewfinder ) and the image is very clear, not blury. When I switch back to the photo camera, the fps of the preview goes down and the image becomes blury and awful ( even in the Google Camera, even in the stock camera) but when I take a picture in any of these, I get clear images in both.
So! Let's go to the point - The quality of the video call in any of the apps, is the same as in the camera preview mode of the photo mode ( in the viewfinder ). How do I comunicate to these 3rd party apps to use the camera mode/ sensor of the video preview mode? How to make the image durinng a video call be clear and not blury like in the photo preview state? The app code should be edited or the rom?
What I mean is ... let's say I am using Skype for a video call. At the moment of connecting to the camera, what is the way it does this? What code is used? What part of the camera is accessed? When I open the camera app of the device, and trigger between photo/video - I get 2 absolutely different images of the preview ( the viewfinder ). The photo preview is on a low fps, if there is enough light, if I reduce the brighness, the preview fps gets smoother.
But when I swicth to video , I get a very clear image, with a high fps, little noisy and clear. Though, the preview of the photo camera is blury ( noise reducted ) and low on frame rate.
So, the calls in Skype has the exactly same image type like the photo preview, blury and fps low.
Is there any way to drive Skype using the camera type of the video viewfinder? It is a very huge difference in quality, and it is very weird, video calling apps use the worst part of the camera, when there's actually obvious the sensor is a high end one, showing it actually can offer a good quality of the image ( while in video mode ).
Please help, I want to try to develope something related to this. How does an app choose how to use phone's camera?
So tonight I noticed in video mode at 1080p 60fps there is a bit of an issue. The video is clear at 1.0x regular zoom but once you switch to wide angle at 0.6x the video is all blurry and not very focused. Once you go back to 1.0x it's better again. Any other resolution wide angle is fine. Just the 60fps I notice this. Anyone else?

As far as I have noticed, the wide angle lens displays the same issue in video mode no matter what video mode you choose.
In addition, if you shake abruptly the phone while taking video on any video mode, apart from the 1080p 60fps at 1.0x, video gets unreasonably blurry and jittery.
When recording at 1080p 60fps the video is quite zoomed in, or is it just me?
Am yes, it's blurry with the wide lens. Video does seem to be anything but good on this phone.
I don't know about that exact issue, but the 'jelly effect' is absolutely horrifying on video I have casually taken. I am stuck on .146 though, supposedly there were various camera improvements with .187+?
153 firmware update fixes the video issue completely

Not for me it didn't
I want to ask something about some different video recording situations
What is best video recording options for wide angle video output (quality, stabilisation fps etc...)
What is best video recording options for normal angle video output (quality, stabilisation fps etc...)
What is best video recording options for X3 zoom video output (quality, stabilisation fps etc...)
I see not so many video options but you know what I mean, it's resolution.
Resolution changes the field of view output of video.
What are your settings and why are you using that for different situations.
Shine my dark road with your light of wisdom
I use :
- 1080p 30fps : when I film in a regular way such as filming landscapes, or filming things I don't intend to put an emphasis on
- 1080 60fps : I use this more when I have "living" subject on my frame, such as filming my friends laughing or doing whatever they are up to. The idea is to be able to apply a little slow motion in post to emphasize some moments.
- 120fps : that option is on the slo-mo options. I only use that feature in great lighting and if I intend to create a more dramatic look to the moving subject I wish to apply a slow mo on. But I rarely use that feature since I don't have much opportunity to capture fast moving subject.
I recommend using the Pro mode for video since you can control the focus. (Manual focus, autofocus, focus lock)
Your camera settings depends on what you want to shoot. You will have to play around with all of them and well switch from a mode to another depending on the situation.
30fps provide better image quality
60fps is smoother but somehow less sharp in some situation
120fps don't use it if you don't have enough light otherwise you'll end up with a blurry not sharp not good looking slo-mo.
There are 3rd app such as FilmicPro that gives you more freedom with the camera settings. But I don't use them since I haven't found one that take advantage of the 3 lenses that comes with the Mate 20 Pro. So now I deal with the stock camera in Pro mode.
Hope it helps
This helps a lot. Thanks for posting details.

How to fix video stabilization on note 10 lite. With a normal settings of 1080 with 30fps I get shaky videos (if I mount the mobile in car or try to walk fast on uneven roads). The problem is fixed if I use Ultrawide lense but the issue with that is very poor quality as it is only 8mp cam.
Videos come out as it is wobbling, does anyone have any solution to that?
I have used gcam app using gcamtor but that doesnt work at all
