The image quality is very good.

Just to let you know, the less you move the camera around, the better the video will look.

For one thing, it's a distraction. The other part of it is that the image will blur as you quickly move the camera.

If you can get a hold of a tripod or monopod, it would be optimal. (With a tripod, you would turn off image stabilization.)

Otherwise, if hand-held, always try to steady the shot (keep in mind what you will be viewing later).
Make sure that the the image stabilization is on for hand-held shots. If you must pan, do it very slowly.
