I use Video Editing software (Pinnacle) which came with a card that I plugged into my motherboard. Many new cameras come with a USB type port to upload to the computer where you can then use a variety of software to edit the video, including adding fades, music, sound effects, and removing unwanted noise.
That is pretty cool. Do you have the camera in a housing?
I noticed that CVS pharmacy 'had' a video camera that looked like a disposable camera, and I thought about using an underwater disposable camera housing to record video.
