Windows Movie Maker/Connecting a video device
Webcams are commonly linked up through USB ports.
Mini DV
Mini DV video cameras are linked up to computers via FireWire cables. These come in three varieties:
- 4 pin/4 pin  

4 pin (left) and 6 pin (right) connectors  - 4 pin/6 pin
 - 6 pin/6 pin
 
Cameras commonly have 4 pin sockets. Computers, however, commonly have 6 pin sockets and laptops sometimes have 4 pin or none!
A laptop with no FireWire ports but a PCMCIA card slot can use a PC card with 2 6-pin FireWire sockets. However, it is more convenient to connect it straight to the computer.
