Gopro
Oh man I love it. Sure it makes it a bit difficult because you can't preview any footage. But MAN does that thing kick ass. I was offered a deal with GOPRO because they saw my old footage and liked it so I got mine at wholesale but what a deal. You can get really really great shots for under 400 bucks. The quality these things put out on a sunday day are incredible, mirroring the stuff the pros use.
There are drawbacks, like lack of control of the shot and such. But I think It simplifies everything so much and almost makes your edits more pure. Because you can't really set anything up, it looks exactly how it happens.
So Yeah I LOVE it. Don't know how well it would work with a scooter but I bet if you strapped it to the back and did some tailwhips with it that might look really great.
Check out the other videos on my channel for more examples of the gopro, like the other trampoline edit and the triple backflip.
Cheers.
