I got the Akaso EK7000 action cam in the mail today. The camera works almost perfectly other than one issue I noticed. The issue I noticed is a scrolling line that appears in the video at 4k 25fps. I then took about the same clip in the same conditions at 1080p 60fps and I didn't notice the issue. Here are the clips I took.
Also, the lines on the walls in both clip aren't caused by the camera, they are just shadows from a railing behind me.
I've heard about something called rolling shutter, could this be caused by that at all?
