GoPro Hero 7 Black video glitches [ New ]

Hi all!

Today I've tried recording some POV on my mtb ride and I've discovered strange video glitches:

and

I've used GoPro Hero 7 Black with next settings:

Resolution: 4k

Framerate: 24fps

Stabilization: Auto

View: SuperView

Protune: On

Shutter: Auto

ISO min: 100

ISO max: 400

SD card: SDSQXAF-064G-GN6MA

Firmware: v1.51

In davinci resolve I found that in both videos there 3 issues in next order:

• 3 duplicated frames,
• 1 frame with a stutter on the top of the frame
• 1 duplicated frame not in its possition (duplicates frame before 3 duplicated frames but appears after frame with a stutter)

These issues don't appear in all videos

Anyone knows how it can be fixed?

Thanks for the update. I've found 60fps works best. In lower lighting, I lock the shutter at 1/240 and adjust the ISO, locking the MIN/MAX to the same value. For low light, evening or indoor use, I generally use 4K (4:3)/24fps.

The first glitch might be from writing error to SD card. Not very confident in that guess, but it wouldn't be the first time an SD card caused something line this. Although you are using a recommended card, they can still have periods of not keeping up or have their own manufacturer issue. More likely, the camera processor just glitched. If it's very rare that this happens, I wouldn't worry about it. If it happens frequently, then you might need to exchange the camera. A manual update of the firmware and a factory reset after is a good idea to try for now.

The second video looks to being caused by low light. A slower shutter and Hypersmooth stabilization do not mix. Try locking the MIN and MAX ISO at 400 or even 800 in lower light. Alternatively, film in 60fps with a shutter locked at 1/240. If you want to stick with 4K/24fps, then using the (4:3) format when in lower light might also be beneficial as it uses a less aggressive stabilization.

I've manually updated firmware, formatted sd card and done factory reset.
Tried today with increased max ISO to 800 but experienced the same issue during walking. Can superview be the cause of this issue?

[danielr15]

It might be contributing, but blur/warping is usually a result of the Hypersmooth trying to make adjustments with less frames and longer exposure times. In bright lighting it tends to work best as the camera uses a faster shutter so each frame is more sharp and crisp. Having more frames allows for more subtle adjustments between each frame. Since Superview is using the entire sensor, it's possible that the camera has less workable area, although the 10% crop should be compensating for that. Since Superview is really just 4:3 pinched at the top and bottom and then dynamically stretched to a 16:9, I suspect that it might also be more susceptible to distortion, and therefore making it more difficult for the camera to accurately hold the frame. I'm really not sure about that though.

So later today I've tried recording footage in 30fps with same other settings and this issue didn't occur
