The good thing about youtube is you can learn everything about it and how to do it, on it. GoPro's are good but some have a real fish eye / wide angle thing going on that wouldn't look good for everything. Higher end phones can get you pretty far but you'll need a gimble for it and of course a good mic. A shotgun mic can get you far but a lapel would be best. Start there, Adobe premier pro is good for editing, watch tutorials on youtube, the basics are very straight forward and fortunately that's what people like best, basic. Not long intros and flashy crap all over the place.

I urge anyone with wrench skills, old fashion know how and a garage full of cool stuff to pick up the camera - and you dont need to be on camera if you dont want to be. AvE has 1 million plus subscribers and has never shown or said who he is.
