Choppy video?

[philliplavelle]

Just wondering if anybody has been noticing video looking choppy? I shot this yesterday on my phone using 4K 3840x2160.. bit disappointed.

Don't want to have to shoot in FHD or 8K.
Any ideas?

Were you using 60fps? I haven't tried 4k yet. I did shoot an 8k video and while shakey it wasn't choppy.

I don't believe I was.
I used what the settings said was 4K 3840x2160.
(There is an option for 4K at 60fps above this, so presumably the above one is 30fps?)

Yes I've gotten this before. Try closing out all background apps and disabling stabilization. 30fps shouldn't be choppy like that.

I just wanted to say that I got the same choppiness on both the S10 and ultra today, identical. I wonder what the problem is? I done a TON of filming with the S10 over the past year and don't recall this choppiness in video, could it be something wrong with the newest updates?

Same exact same problem here. It's frame-skipping issue where the frame rate is incorrect.

After tons of research, it seems that the problem is that the phone can't handle or is not set to "constant" 29.97 FPS in 4K or 23.98 FPS in 8K as expected. If you open the details of any of video file you created, it shows either at 23.20FPS for 8K or something similar instead of of 23.98 like it supposed to be, so players are adding artifacts or choppiness video.

The worst is when you record 4K with all the package activated (HDR10+ with image Stabilization and auto-focusing) where instead of 29.97 FPS as expected, it's between 27fps and 28 fps which is abnormal frame per seconds.

The temporary workaround is to disabled one of the two (HDR10+ or IMage Stabilization) and then 4K video will be at 29.97. As for 8K, the only workaround is to "reencode" to file making sure it's set to "constant" 23.98 fps (losing some frames).

I am on the Snapdragon 865 by the way.

The best player I have found to reproduce the proper image (HDR10) is MPV (you got to be full screen and ensure to make a config file and have in it a line hwdec=nvdec-copy . Not too sure why the copy makes thing works, but it does . VLC is giving me the wrong gamma and contrast, but this one is perfect so far.

Conclusion so far :
I can see, both in 4K and 8K, when HDR10+ (BT.2020) is on the videos are missing frames (so either choppy or giving us vertical lines and artifacts). Samsung has to release a fix as they sold us the phone with these nice feature that are broken. It's a very pricey phone.

Auto Focus is always doing something (focusing-refocusing), this also has to be fixed.

Samsung S20 Ultra 8K Vertical Lines (On my 2080ti rendering the frames, other 8K video with same codec works fine).

I am not impress with the camera system/software on that phone so far. It might not be about the hardware, but the software that is not optimized, but who knows! The bottom line is that I bought this smartphone to get rid of my big mirror less when on a field trip to shoot videos in HDR10 so I can benefit (on my OLED's) and it's not even an option now. Even not an option to change the framerate to 24pfs(movie) in 4K. On top of this, third party application are not allowed to use all the lenses and on the back and the HDR and 8K. The only lens working "as it should" for me so far is the front one. All others on the back are problematic with wrong colours.

If Samsung can release an update soon, that will be great.

When I click details I don't see frames per second

Transfer the video to Windows or your Mac. You'll see it from there. The only mode that work without frame-skipping so far is "4K 60FPS, NO HEVC, NO HDR and no auto-focus on (auto-focus is broken anyways). This smartphone is a real joke.
