Video stabilization problem - Samsung Galaxy S21 Questions

I was trying to compare samsung camera with some gcam versions and when I activated video stabilization in stock camera, just before recording a video, the image quality degradated a lot, it was almost blurry. Is it a bug that came out with last update? If I remove the stabilization I have 0 problems.

When the phone was out the option was actually reversed, so you get stabilization if the option was off, not sure how is it now

[Q] Full hd video camera's field of view

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...

Video Stabilization off when setting is set to "on" and vice versa.

Anyone notice that one the T-Mobile Edge, that when you set "Video Stabilization" to "On" it actually doesnt stabilize the video?
Only when you set it to "off," it'll stabilized the video recording?
It's kind of the opposite, not sure why no one else noticed.
Could be wrong here, but I believe that while recording you not going to notice any stabilization. It's happening but you won't see it until replaying the processed video after the recording is done.

To check video and photo stabilization, try zooming in to 3x, point it at something and try to do a recording with it On and off, the video will do the opposite.
It work none the less, but it's counter intuitive to have it day off when it's actually on.
OP seems to be spot on. Same problem with my regular S6. Video stabilization = off turns stabilization on. With it = on, videos are jittery as hell where even my pulse through my fingertips causes the camera to shake.
So guess there's a bug in the camera app.
I just noticed the same thing with my unbranded regular Galaxy S6. If you have video stabilization turned on in camera app settings it is in fact turned off. I was surprised how poorly it stabilizes the video, so I had to use 'Stabilize' option in YouTube. Then I thought maybe my optical image stabilization component is damaged so I started playing with it and once I turned it off my video stabilization started to work very well. So it seems to be a bug in camera software. Anyway - if you want to have video stabilization you need to have it turned off Samsung logic
The reasoning is because the video stabilization setting in the camera app turns on DIGITAL Image Stabilizing by Samsung via software which is really just counterproductive to the Optical Image Stabilization already built into the camera.
So yeah, trust the OIS hardware because typically hardware > software in this field.

Just a question so OIS is default by default and always on am I right? Even on UHD recording?
More evidence that the switch in the camera options refers to DIGITAL image stabilization:
Set video resolution to FHD (not the 60fps option). Otherwise, the Video Stabilization setting is not available (grayed out).
Set the Video Stabilization setting to "ON".
Go back to the camera, zoom in fully (8x). While pointing at something easily identifiable, without shooting video, note that the image is stabilized quite well -- you can simulate "shaky hands" and the image is very stable, not jittery. However, you are not shooting video yet, so settings specific to video are not activated. What's happening here is the OIS is working, and doing a very good job.
Now, click the video recording button. You will notice two changes in the image: It will zoom in a little bit more without any zooming input from you, and the image will get rather UNSTABLE.
It turns out, what you had selected in the settings is actually, truly, being invoked. No, this is not a bug. The switch is not acting the opposite of how its labeled, even though the RESULT is exactly that in practice.
Here's what's happening: As someone else noted, that switch controls digital image stabilization. This is a software process, that basically crops off a small margin all the way around the picture and reserves these pixels for calculating a smaller moving "window" in the larger captured image space. The software tries to move this window around so that it follows the random small movements from jiggling, unsteady hands, etc. In this way, the image appears stable rather than moving around in the capture space.
This is why, when DIS is turned on, the displayed image zooms a little bit -- that's the "reserve image edges" being cropped off and the remaining image being expanded into the display area.
So, here's what I think is happening: When you have Video Stabilization on, the phone turns off OIS and enables the DIS algorithm. The OIS camera hardware is something like a Googolplex times better as IS than Samsung's crappy algorithm, so the end result is the appearance of IS being turned OFF and a little loss of resolution of the video image as well.
Once the video is stopped, after a few seconds you'll see the DIS turned off, OIS turned back on, and the image will zoom out a tiny bit and become very stable again.
Bottom line: The Video Stabilization setting in the S6 camera app is worse than useless. It's adverse. It should be left off at all times under all conditions.
How did this happen? My guess is, the engineering team responsible for the hardware was organizationally distant enough from the camera software team (keep in mind the latter are trying to develop an app that can run across many phones). The hardware guys put this incredible camera in the phone with awesome OIS. The software guys, not focused only on the S6, passed through the DIS that's been in the camera app forever, and no one engineer was responsible for integrating all this stuff for the camera feature itself, testing it, making sense of it, blah blah blah.
And here we are.
Bottom line: Because of the OIS in the S6, the DIS feature in the camera app is unnecessary and should be left OFF. In fact, the way it works misleads the user into thinking IS can't be had with the video resolutions higher than non-60fps FHD. In fact, exceptional IS is available at all times in all resolutions for stills and video -- the hardware OIS is always on the job, unless you turn it off by turning on the [digital] Video Stabilization option in the settings.
The only bug here, if any, is that this setting seems to turn off OIS, when it doesn't need to. Perhaps with OIS on, and the DIS processing applied to that stabilized image, we might get something even better than OIS alone. Alas...

1080p 60fps issue

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+?

Camera App Fixes?

I've watched a couple of reviews and read others regarding the camera apps and performance, such as the erratic HDR performance and slow switching between cameras, RAW support not available in all cameras, frame rates in video, and so on.
Notably this one: https://www.youtube.com/watch?v=fjSX1j4WBRo and this one: https://www.youtube.com/watch?v=TrZAb4dUfHQ
Has Sony since then launched updates to fix these issues?
Avoid this phone if you;re planning using camera. None of it has been fixed...

the launch speed of the camera is normal like the other high-end, there is just the ultra-wide angle or there is a delay but on most other smartphones this delay also exists. For the range I did not notice anything strange, it is normal and not exaggerated (the dynamic range is different from the HDR which is purely software to access it must pass a manual mode), for the rest it acts as their camera (for example in landscape there will be the backlight settings but if there is a human in front of the forces will highlight the face ...). For example, there will be a photo in auto on the stock camera and Google cam HDR +, I much prefer the rendering, the details, the noise of the camera stock.
Camera works fine, dont believe everything you see on the internet. I have this phone since september and camera app has not crashed once since then. So, yeah..
I hope they will finally fix lack of 21:9 mode in main camera, lack of 4k 60fps and 4k video stabilisation crap that actually is disaster...
None of those were fixed :/

21:9 photo mode is pointless when you can take a 4:3 photo and zoom in to 21:9.
That's all the 21:9 mode would do so not much point investing it in

Question video stabilization (OIS)

noticed that there is no optical stabilization in the stock camera application in any video shooting mode. After that, I launched the Google camera, where the module moves as expected. In photo mode, the camera moves.The question is just for me or is it such a stabilization system, I read somewhere that the optics walk a little bit, but I did not notice any movements.

One Plus 9R does support OIS(Optical Image Stabilization) and it is available only for the main camera.
OIS is a physical thing you cannot disable. It's built into the camera itself. So it "works" in every app. There is digital image stabilization that some phones use, but it will never be as good as OIS. Some phones, like the iPhone 13 Pro Max (maybe 12 too), use a "Sensor Shift OIS" technology, an even better OIS.
So in short: Sensor Shift OIS (iPhone) > OIS (optical image stabilization) >>>> digital image stabilization (other phones, software solutions, etc.)
