Cool video. What kind of camera do you have and how do you have it mounted?
I agree on the flip lines, I have on on either side at all times no matter what the river or run. I also have one on me to go with the ones on the raft. Not a bad idea to have them pre-installed anyway, large or small. When the boat is light, you can flip right away. If it's heavy, at least they are there for when you can get to a reasonable place with the right amount of help.
A tripod would be cool, been thinking about good ways to mount a camera myself. A helmet cam would be cool, but may be a bit shaky. The downside to mounting a camera on a tripod is that it could get trashed in a flip or by bodies flying around the boat.
