Image stabilisation makes the footage jellyish

[ New ]

Good afternoon,

 

I've recently purchased a Hero9 Black and tested it in full auto mode using the presets available. I was at the park on a bright day and the footage was ok besides some extra saturation and weird sharpening.

 

Later that day, as the sky began getting cloudy, I could notice that my footage started looking like jelly/shakey. By looking on the internet, I saw that is probaly due to image stabilization not working properly in poor light conditions. This would make the shutter speed decrease and the resulting blur would mess the stabilization software.

 

I have then updated the camera to its latest firmware and ran a few tests. I tried protune shooting 4k 30fps by setting shutter speed at 1/60 and later 1/120 and my ISO range set from 100 to 1600. The footage still looks weird and shakey like the stabilization actually makes the image flicker.

 

Now I don't understand. Does the Gopro make the shutter speed decrease when needed regardelss if I had manually set it with protune?

Should I start considering to contact support for a potential defective camera? 

 

Thank you for your help.

Hi @lucad12314

 

Do you observe the same with other resolutions?

Would you be able to share a sample file?

You may also reach out to our Support Team through https://gopro.com/help/ContactUs to have this checked further.

 

Thanks!

Ej

Thanks for the sample files.

What version is the camera on?

Was Linear+Horizon Leveling selected on these recordings?

Have you tried other settings?

 

Thanks!

Recent tests walking in low light showed the limit at 1/200 (shutter speed) wasn't enough with Boost stabilization, perhaps 1/400 with boost.

Hello Ej,

 

Version is 01.50

Linear+Horizon leveling was indeed selected

 

I tried yesterday using the handler to have the camera more steady and tried the follwing:

 

- 4k 24 fps with 1/48 shutter, ISO 100-1600 

- 4k 24 fps with 1/96 shutter ,ISO 100-1600

- 4k 30 and 60 fps with both 1/60 and 1/120, ISO 100-1600

 

I also tried without Hohrizon leveling and the image stabilisation is always set to minimum.

I am also using the SD Card that comes with the bundle. The SanDisk Extreme 32GB microSDHC 

 

Thank you.
