Hello there,
Movie Maker was designed for digital work. In the case of the device it
connects to this means firewire. The manual for your camera will give
directions on what firewire connector it requires as will your firewire
terminal on your computer (often a PCI card). If your computer does not yet
have a firewire port and assuming it is not a laptop or smaller, you will
need a PCI firewire card and cable.
