Oops- just noticed that the first 30secs of the video is a clip from another location altogether (River Tweed in October)! I'll fix it later.
I use a Fuji S5700/5800/5900 (can't remember which model exactly). It was a cheapo SLR style still digital camera which takes video at 640x480 30fps. It's perfect for hover work as the batteries seem to last for hours and it saves having to carry both a video AND still camera.
