Tested the cam for positioning while sitting the bike......seems about right, but only riding it will confirm.
I've managed to circumvent MS's restrictions on installing HEVC codecs and they're now installed......so I can view 4K vids straight from the camera.
The issue with the 4K stuff is the file size, and bearing in mind that YouTube and FaceBook seem to compress them down to 1080k there doesn't seem any point in using 4K. At least not at the moment.
I've enhanced 1080k to it's optimal settings and there was hardly any difference between that and 4k. Except the file was about a quarter of the size.
Anyway, I'll give it a test on the bike tomorrow.
