I started with a Fuji Finepix still camera on movie mode. It did 360X480 O.K for up to 30 minutes, but didn't work in the cold. I then bought a Canon HG10. It was a total disaster in the air. Even when I had the vibration solved, it produced weird effects.
I'm now using a Panasonic DMC-FT2 still camera, which does only 10 minute shoots, then start button has to be pressed.It has a 32G card, though, and good battery life. It is slow to focus. Video taken with it in cold conditions is on the PPRUNE video thread, and others from the Finepix are there if you click YouTube for other videos. I got nothing useable with the Canon.
