A ride on Revolution with the Zi6 in hand, and the whole clip run through Smoothcam afterward to see what a camera under $200 can manage. The answer is pretty well, all things considered, though the stabilization takes the rolling shutter and makes it worse, until the frame is wobbling like jello on every turn. Skewing the footage probably would have straightened most of that out.
As for the silliness at the end, there is no defending it. Apologies in advance.
