S21+ camera slow motion video jitter and loss of fps

[PrashanthSri]

I am facing issues with my S21+'s slo-mo feature.. the video is jittery.. 

While playing the slow mo video the fps drops below 30 which makes the slomo video look choppy.. 

Anyone having the same issue or was anyone able to solve this issue?

I have the same issue with S21 Ultra, I have noticed that if I keep the camera fixed and shoot moving subjects the issue is not that much. It's only when I want to move the phone and create slow motion videos of still subjects that the issues become prominent. It's an Exynos unit and I am assuming it's either the issue with focus of camera or with the processor.

Definitely a software issue, my phone was flashed with a new software and slowmo was working perfectly for couple of days and slowly started getting jittery as time passed.. I thing some cache related issue is causing it. Samsung can fix it if they want.. but not sure if they will.. I've seen similar issues in previous gen devices like s20 plus and note 20 ultra.. specifically the devices that were updated to one ui 3.1

Did the update fix the slow motion problem? I have the same and if the slow motion video is running for a long time the camera automatically shuts down

No.. it's not fixed yet.. 😕

Have you tried gcam? I was facing same issue with gcam as well

Ya I tried other 3rd party camera applications, 120fps slowmo works fine.. 240 fps slow motion gets captured only with 230 fps or lesser.. so while the conversion from this lesser fps video to a 30 or 60 fps output causes this jitters..

Hopefully this fixes the issue..
