Gopro Hero 7 2.7K60 stabilization problem?

What happened to hypersmooth in the 11th second of my movie? It looks like hitting the ground ruined the hypersmooth. I record video in 2.7K for the first time. It never happened when using 1080p60. Firmware 1.51

Hi @greenhero36067,

 

May I know the SD card you're using? 

 

Looks like it was triggered due to sudden change of the vibration. 

But if it's happening on a flat surface we need to check for other possible problem.

Thanks for letting us know @greenhero36067,

 

Please let us know if you'll encounter that on a flat surface as well without a sudden change on terrain. 

So that we can report that issue.

For now, this has happened only once. If it happens again I will let you know.

@greenhero36067

Might be a rolling shutter. A faster shutter might have avoided this.  While you have the fps set to 60, you also have Auto Low light on, meaning the camera can adjust to a lower fps in low light.  It's usually best to keep this setting off.  Your MAX ISO is 1600. which is good for a faster shutter and fps, but the MIN being at ISO 100 might have allowed the shutter to go too slow.  In environments like this, you might benefit from having a higher MIN ISO (200 might be OK, but 400 is probably best).  Doing so will prevent the shutter from dropping too slow in an attempt to use the lowest ISO.  Other options to try are fps - 60, Auto Low Light - OFF, Shutter Locked - 1/960 (can also try 1/480 or 1/240), Lowest ISO MIN/MAX possible, Sharpness -  Medium (personal preference, but High requires more in camera processing and can create too much contrast), Color - Flat (Again, personal preference for more detail in shadow).

 

In a screen grab, you can see the two images being written on the same frame due to high vibration and slow shutter

Rolling shutter does not *ever* cause effects like this.   Rolling shutter creates skew during fast horizontal panning, compression or stretching during fast vertical panning and jello during high frequency vibration.   It does not cause violent shaking of the entire image when the camera is otherwise moving relatively slowly nor a weird rectangular block to appear only on the left side of the frame as visible in your screenshot.   And fast movement with too slow of a shutter speed causes motion blur, nothing more.

 

This looks like a less extreme version of the same issue reported in this thread

https://community.gopro.com/t5/Cameras/Hero-7-Black-Hypersmooth-failure-Super-glitchy-warped-footage...

And royalstorm0157  posted raw clips showing the same issue at the end of the same thread, including a sample that shows the same rectangular block on the left side of the image.     Have to download the video to see it clearly, but it's very clearly the same problem.

The two effects together represent a total failure of the EIS and image processing.    I sure hope *someone* at GoPro is taking the issue more seriously than what I've seen here so far.
