Recording Video

Ok, I want to record video for as long as possible on my Macbook. Do I use iMovie, iCam, Photobooth, or a combination thereof? Sorry to be a jerk, but I sort of need to know the answer fast lol.

I don't know what "iCam" is so I can't help you with that. I would have thought simply using Quicktime X on Snow Leopard would have been the simplest solution, but they all access the same camera and record to whatever format you specify so it really doesn't matter.
