it’s an interesting viewpoint but for me IMHO five minutes of what is effectively the same shot (at a 45 degree angle for some reason) is too long.
If it’s just a record of a ride, that’s fine but if you want a watchable video you should change mounting positions from fork to frame to helmet to backward looking etc. and cut the shots together.
Take the music video approach where a segment of film of say 15 seconds is the maximum length before changing to another shot.
Another rider in shot the majority of the time always makes a video more interesting too.
But it’s all a matter of opinion and as i said already, as a record of you and your mate riding the Jetlag trail (is that new, I don’t know it) it does what it says on the tin.
