example of shutter effect on stabilization in low light and an example of handlebar in the night[ New ]
I made some tests that show the benefits of shutter speed increase on hypersmooth boost.
- GoPro is not meant for stabilization in low light. period.
- in low light ISO is pushed at maximum, shutter is 1/fps to compensate the lack of light.
- at 1/25 shutter the image itself is jelly, because of the move.
- this jelly frame is unusable by the stabilization algorithm.
- remember the lens has a f-stop f/2.8, not very good in low light.
- as well the sensor is a fingernail surface wide.
- by no means, you can compare these gears with a DSLR or mirrorless full-frame sensor (as big as our touch screen monitor) with ISO to 26500 with big pixels and using a lens f/1.4 that capture 4 times more light than f/2.8
but we can enhance his performances in low light, even obtain a decent stabilization, without jelly/jumping image.
my tests are here:
ISO =800 (1600 for 1/100)
hypersmooth = boost (off for reference)
shutter auto in low lights means in this case 1/25sec
at 1/50 we have already improvements.
with shutter 1/100 even in low light the stabilization works well.
at 1/100 the frame image is stable, no jelly, therefore the stabilization algorithm ca use it.
I want to share with you parts of the last evening commute, handlebar-mounted, 4K 25fps Superview, hypersmooth can be only on, shutter 1/50, ISO Max = 800.... (I wish I left ISO 1600 to have a brighter image...)

in this case shutter cannot be set.
in my case the exposure area was in front of the bike, lower than the middle and a little bit on the right.
it is better than shutter locked at 1/50 as previous evening.
just wanted to share with you,
