I have a gopro hero 6, that when I see the stabilization option it shows me the message that is reduced by 10%, but I've seen it in promotional videos and reviews that would be reduced by 5%
please search the post "HERO6 Black v01.60"
@ryanv12566 forwarded the issue to the developers.
that 5% is on a side...so 10% overall... please read also the post....
enjoy your hero6!
