Issue with horizon leveling

[ New ]

I just received my GoPro 9 today, however it seems like the camera is faulty. It looks like there is a problem with the horizon leveling. If I rotate the camera left and right (like turning a car steering wheel), from approximately 15 degrees to -15 degrees and back again repeatedly, the camera keeps the level, but the image vibrates.

Thanks everyone for your help and comments. I can confirm that it is a low light issue. I tested the camera in good lighting conditions and there were no vibrations. In low light there will need to be some adjustment of the settings.

Re: Issue with horizon leveling

In low-light conditions you can try the following:

 

1. The most effective way to reduce the vibration is to change the shutter speed. I changed it from Auto to 1/200 seconds (the denominator is 4 times the frame rate) and that worked well. The downside is that you can get motion blur if the shutter speed is too low.

2. You can increase the ISO Max setting to let more light in, however I find that anything over 800 is too grainy. Usually I set mine to 400.

3. If your hypersmooth is set to 'Boost' or 'High', you can lower it to 'On'.

The camera has the latest firmware, so something else is causing the issue

Hello @peak76825

 

What were the rest of the settings used in this video?

What SD card are you using?

 

If the last update has not been done manually, we recommend doing so.

Let us know how it goes.

 

Thanks!

Hi, the setting are:

 

Resolution: 2.7K

FPS: 50

Lens: Wide

Hypersmooth: High

Duration: No Limit

Hindsight: Off

Scheduled Capture: Off

Photo Timer: Off

 

PROTUNE

Bit Rate: Low

Shutter: Auto

EV Comp: 0

ISO Min: 100

ISO Limit: 400

White Balance: Auto

Sharpness: Low

Color: Flat

RAW Audio: Off

Wind: Off

 

The SD card is the free 32GB SanDisk Extreme card that I got from GoPro in the box as part of the bundle.

 

The camera has the latest firmware (1.21). I did the update first thing before I started using it.

 

I tried taking videos with many different settings and I still get the same result. A slight rotational movement of the camera causes the vibrations. The only plausible explanation that I can think of is that the camera has a fault.

Sorry, I made a mistake. The Lens is Linear + Horizon Leveling (not Wide).

 

The vibrations only occur when I'm using Horizon Leveling.

hi,

the problem may be that low light.

 

the ISO 400 will push for sure the shutter to 1/50s (the max 50fps permits).

 

at 1/50 any quick move generates a blurred frame.

stabilization needs crisp frames.

what you see are these blurred frames taken as reference frames by the stabilization algorithm.

 

in low light, when using stabilization, "force" the shutter to 1/200  ....or 1/(4*fps) 

 

make the same test in bright light...

 

just me,

robert

I still get the vibrations, even if I increase the ISO Limit and shoot on a bright sunny day. I think it's a fault with the camera.

You're shooting in very very low light conditions and as a result, the EIS (hypersmooth) is causing blur in the picture.  You need to manually adjust your shutter speed to eliminate the blur.

Hi, same issue here.

The real issue is that every place is in low light conditions for this new GoPro 9, so every video recorded is blurred. it seams like the only way is to set the shutter speed manually and more than 1/200 or 1/240. The same also if HL is disabled.....

ISO starting from 1600 are sooooo really bad....

Have we hope in a new firmware update or have we go with a refund? this is the real issue..... i felt better with my gopro 6 that remained simply unstabilized with low light condition but with no blurred effect

Only use Hypersmooth “On” in low light conditions. Even better if you can turn it off.

Did you force the shutterspeed? What about the ISO settings? Thanks

hi,

 

all default.

let's see what shutter and ISO camera used around 1/300 and ISO close to 1600

 

the camera will prefer a higher ISO to obtain as fast shutter as he can.

probably the algorithm is also related to FOV, hypersmooth and other settings.

 

 

 

at sec.16 on no-boost

shutter ~1/370

ISO ~ 1600

 

at sec 11. on boost

shutter ~1/300

ISO ~1300

Re: Issue with horizon leveling

yes indeed.

 

here are my workarounds:

 

I made some 3200 and 6400 ISO tests in the living room in the evening - 3200 can be used, 6400 has too much color noise.

here is up to every user to decide.

 

https://youtu.be/m8euFEQg37A

 

under the bridge is low light and very bumpy, but stabilization was good.

I let the dove's flight....just for fun.

4k25fps SuperView, hypersmooth 3.0 = on (no boost), all rest as default (iso max=1600)

 

https://youtu.be/MkFmtoEimAs

 

from my experience what influence the stabilization:

  1. crisp frames
    • the equivalent shutter to be  1/(x*fps) where x=2 or better 4 
      • in auto to have enough ISO the shutter not to drop below
      • manual shutter
      • EV -1
      • exposure control
  2. scenery
    • best when you have a wide-open scene, a horizon like
    • if in the woods, the passing by trees and the continuous changing horizon (only a narrow trail in the front) is not helping the software to "anchor" the image
    • in the night when street lights, these are "jumping" unless the shutter is fast
    • also in the night, even at headlamp light, not too much image details
  3. lens - a SuperView has narrow margins between the cropped image and the entire sensor
    • the narrow the FOV, the best hypersmooth
    • for 9, that has boost on all combination resolution/fps/lens, should not be an issue - still for heavy movements could count
