Here's some from a ContourHD 1080p (shot at 60fps 720p mode). Keep in mind that we started in the evening and went on into full nighttime, and these cameras don't do very well in low light.
And here's some helmet-mounted:
Overall, I'd give the Contour a 6 out of 10. It does seem to be quite tough; it's gone flying off the bike, been hit on tree branches, been in heavy rain, keeps working. The lens cover scratches easily if you're trying to wipe mud off it, and replacements are rather expensive... if I have to buy any more, I'll just find a glass lens in that size instead of plastic.
