I have recently updated to firmware 01.60 and was hoping this would be solved but unfortunately it has not (although the low light image quality/grain is MUCH better).
The image stabiliation performs brilliantly when the sun is shinning and it is midday. Unfortunately the same cannot be said for any other lighting conditions.
When light conditions are not perfect the image stabiliation is clearly jumpy which is almost certainly down to it being EIS (trying to focus too aggressively).
See the video below I took this morning. It was taken at 7:00am in England, and weather conditions were cloudy but not too dark. Video mode 2.7k 50fps Linear. The image stabiliation is completely ruining the video and it is unusable because of it.
Solved! Go to Solution.

thank you for your responses....!!!!
seems that at 50fps we need to go at 1/200 - 1/400 shutter speed to have a good stabilization.
1/100 is better than 1/50, still...
make sense all we discussed here... in bright light, the shutter will much fast than 1/400 for example.....
have a good one!

Pretty crappy suggestion considering the size of the thing. I don't really want to have to lug a big gimbal around with me especially as I have the gopro for travelling solo. Imagine being that guy with a gimbal set up, no one will even want to know you.

hi...I wrote this on other post...
hero5 disable EIS in LOW light at 30fps
at 60fps, EIS remains on....if AutoLowLight is off
I made long time ago some tests:
keeping this in mind, in low light, there is not enough info in the image to make EIS happens.
split the thinking between fps and shutter speed.
at 30fps, the camera will save 30 frames in one second, every frame having a shutter speed between maximum 1/30sec to whatever is the minimum camera can 1/240, 1/1000, 1/8000, etc.
if shutter speed is 1/30, the frames are blurry for motions, but the result in the footage is a smooth movement.
if shutter speed is 1/120, every frame will be crisp, the movement is freezed, but the result in the footage can be a hopping like image, a chopped one....
think that at 30fps, in low light, the shutter Auto will be push to the max, at 1/30sec
(when plenty of light, shutter may be 1/240 etc....)
the frames captured at this shutter speed are blurry
If GoPro consider at one moment, that blurry frame as the stabilized one, the result may be that strange artefact stabilization result.
so with PT on, 30fps, I forced shutter to 1/60
the stabilized footage looks better, but, ofcourse is more darker, ISO, if let, will increase, grainy, grainy means blurry also, etc.
everithing in life and technology has a price, and needs a balance.

I actually thought of this myself and in the video I posted the shutter speed is 1/100 as I was aware that a lower shutter speed may be causing the issue, unfortunately as you can see this issue is still there. Perhaps because of the raised ISO but to be honest it doesn't look grainy to me?
I think it's fairly poor to be honest and I'd rather not spend a lot of money on a ginbal to fix this.
As I said above GoPro should offer a "less stabilised" option i.e. high, medium, and low stabilisation so you can choose what you want. The reason this seems to be happening is because the EIS is so aggressive which is great for bright liht but awful anytime else..

exactly how I characterized the EIS from the beginning...too aggressive...!!!!!!!
In some conditions works fantastic.
see the same trail with karma grip (mounted on my chest) (look at the mtb movements to have an ideea of the terrain...)
and with EIS, mounted on my handlebar
which proof EIS is fantastic...in certain conditions.
in these conditions, I barely need the karma grip......
...a very good idea indeed to have that gradual stabilization.... but, maybe, self tunning based on light conditions and image content....
