Hi,
I was testing the super slow video and after the record i found that the video look like frame interpolation... It is like in TV when you maximize motion plus etc some fake frames are inserted and you can see artifacts on moving objects. The same behave i was able to get when i was using gorpo app to make super slow motion form 60FPS. Anyone know what is the speed that samsung is using to capture super slow video? 240fps? As for the reference i was using s10+ for the same video that i paste the link below and there was no artifacts, just clear items floating in glass. On video below that is recorded via 23u you can see artifacts on closer side of the glass... That is very strange... Can't belivethat flagship is using frame interpolation for super slow video...

EDIT:
I found the answer on samsung website:
On Galaxy S23 Series, users can record approximately 0.5 second of video captured at 240fps and digitally enhance the video to 960fps with approximately 16 seconds of playback. Playback time can be edited in Super Slow-mo player.
So no true 960fps like in s10+ but digitally enhanced so frame interpolation.... That is downgrade actually when you want to record really fast objects like in vide that i posted
Probably, but that's not necessarily a drawback
@zSyntex
But with fast moving objects it creates artefacts like in my video. I was using quite often super slow motion in work to and never have issue like this on s10+. I know that it is just a phone and i have special camera that capture 5000fps but it is quite sophisticated and time consuming to set it up, phone was quicker and sometimes shows what i need without special equipment.

Of course, it's like frame insertion or like the TV interpalotaion for 120Hz content.
But probably it will be more difficult to achieve high frame with these resolutions

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...
Hello.
is it possible to take a slow motion video like with the Samsung S7?
The video starts in normal speed, then changed in slow motion speed and goes back to normal speed...
So you can make a video and anytime you change for a short time into the slow motion mode.
Is this possible with tha Alpha or ss there a solution for it?
Thank you,
kind regards!
looks like you have to install some video editor
No, It is Immpossible! Different hardware stuffing
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?
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.

Has anyone tried recording 4K at 60fps using Open Camera?
I'm thinking of buying this phone but there are others around the same price that support that.
I have an Xperia XA2 Ultra. Open Camera allows the main selfie camera to record video in 4K 30fps when by default
it can only record 1080p
Could anyone try the app and let me know?
I would really appreciate it
"Serious Camera Error" when 4k 60fps is set.

I just installed open camera, though I dont find the HDR option in video settings, but setting to 4k/60 with max buffer of 200 seems to record without a problem. I tried front facing camera, same goes...
I dont see an issue but again, I dont see HDR option in it, also the selfie camera on photo mode, max buffer and max quality seems only as good as normal camera app, the default camera app maybe even a little sharper but barely noticeable but if you really care for 60fps both back and front worked in [email protected] which is weird lol I never expected that, I need to go further testing to see how good the open camera is, compare 60fps in 4k to 60fps 30 and compare quality as well to get the full idea, but I did play around with photos a little bit, and to be honest open camera seemed to have much more artificial sharpness, the photo zoomed out looks sharp even sharper than default camera, but put on a big screen or zoomed in, the default camera has much more respectable sharpness that has way less noise and grain which makes the photo more realistic and more natural overall thats why I feel like the open camera is just a gimmick, all it can provide is 60fps in 4k in both cameras, but again I have to check the quality to see if its even worth it because even with quick tweaking in open camera, I still cant get the best combination of brightness sharpness and color accuracy, yet the default camera app gives a splendid true mix of those, maybe going deeper in manual settings adjusting all these aspects manually could lead to good quality outcomes, but to be honest, no one will ever want to adjust every time they wanna take a pic/video so yah
Thanks a lot Man
I get a lot of noise when recording 4K with the selfie camera, maybe because it wasn't meant to do that or it is just Open Camera.
Thanks again
