This one tip will make your videos better: Move the camera to meet your subject. If you're shooting children, get low. If you're shooting skyscrapers, try an aerial view. And if you're shooting a surf sequence, find the nearest point break and get into the barrel of the wave.
The only problem with the latter scenario is budgeting for an HD camera, underwater camera housing, and an expensive insurance policy since underwater housings fail with surprising frequency. Or, you could pick up a GoPro HD Hero ($259 to $299 depending on configuration).
