Use more lighting than you thought you'd need. If you can take the same scenes with more than one video camera, that would be good. I can mix and edit with what I have here. Don't hold the camera in your hand. Mount it on a tripod, and try not to touch it.
Camera shake is the sign of an amateur at work.
If you have more than two cameras, mount them all on tripods except one, which you can use as handheld. If you want to write a script and tell a story, that would be excellent. Failing that, short clips would be fine. If you need advice on a storyline, I can help. I can then digitise the action, and make AVI and MPG clips from it.
