Battery life on the GoPro? It's been a while, but I'm thinking at least 1:30 possibly more like 3:00? I think some depends on capture settings. It is a removable battery, so a spare could be used.
The GoPro is nice for its toughness, and mounting options. I've used mine underwater with no trouble. In a recently watched YT video, I noticed a GoPro mount stuck to a vise on a metalworking machine.
Upon further review... I have a wide range of camera gear available to test out... all of it older gear, batteries are probably the tricky part...
The GoPro Hero3+, and a bunch of mounting gear
a couple of Flip Minos *one of them free, found at the transfer station...
Ipod touch
Iphone 6S
a Nikon camera (mirrorless? bridge?) *free, found at the transfer station...
a Canon D-10 DSLR.
a set of Big Softi
lights, a mechanical stabilizer
plenty of tripods from the film camera days...
I'm thinking about making YouTube videos as well, and really need to get a start at shooting and editing some video to get in the groove. I've never done any editing, and I'm sure that will inform camera setup a lot.
My feeling is that the less capable cameras, might make for usable "B roll" or POV shots that I wouldn't risk a DSLR to get. Although I may be fooling myself, as shifts in quality might be visually jarring? At the very least, it might be a way of trying out multiple camera angles with fewer takes.
