Even a mediocre trail and boring riding can be made into a decent edit if you are willing to put the time in, and that means at least 3 (but preferably more) camera angles and a very tight edit. Obviously that takes a considerable amount of effort. And for what really?
Then there’s the additional level of faff they ad to a ride. A friend used to hold us up at the top of every trail to get his gopro right, and then he’d never share the videos because he could never keep up 😈
I lent mine to my tree surgeon colleague and he seems to get some mileage out of it doing little promo clips for his social media etc. It would probably bore other tree surgeons though.
