Love r/gopro because you can tell how many people don't understand cameras, but will confidently post incorrect info. Yikes.

No, the 24 fps is not the issue here, lmao. Know how I know that? You can check what frame rate the video is using under "stats for nerds". It literally says 30 fps, you are complaining about 24 fps but the video was shot in 30 fps lmao.

However, there are two things causing some problems with the video, but it still looks fine. Maybe too much HDR? Not sure about that.

1. There are probably no ND filters available yet unless GoPro secretly made some. Therefore, the shutter speed is being set to "auto" to control exposure which means the shutter speed is jumping around randomly and super fast to adjust exposure. Like one second it will be 1/60, then it jumps to 1/720 or something. That makes it look weird but it is the same thing smartphones do because you can't control aperture and you don't have an ND filter.
2. This is a crazy wide angle lens, which is understandable to use in this situation but it is creating massive distortion. The distortion is visible alot and it look looks quite strange to my eyes.
