Alan, that's a good resolution.
Good for HD television and my monitor but the upload took ages so I might drop it back to 720p for utube etc.
No doubt you'll experiment with voice-over and music to mask the road/wind noise.
The music maybe but doesn't utube have issues with putting music on your home made stuff? As for my voice: I'm not going there.
The versatility of a helmet-mounted system is marred IMHO by the helmet and bike dashboard always being in the frame.
I had a look at that and rearranged the mount so it's out further from the helmet. I'm more inclined to use the cam on helmet in a city environment rather than a rural area but no other option at the moment.
Some years ago I made an aluminium base complete with a rubber pad which I mounted on the RHS police light bracket. The camera attached to the base using a small bolt with the same thread used to mount a camera to a tripod. This arrangement located the camera to the right of the windscreen and had the advantage of being closer to the centre of the road. The obvious disadvantage with my mount arrangement was its fixed position,
With the power supply (charge on the go) on the dash shelf I was going to place a mount on top of the LH mirror but that idea didn't last long as the driving light will eventually be there. Underneath the mirror looks good instead.
