Today's digital camcorders make it easy to transfer both standard-definition and high-definition video from the camcorder to the computer. Whether you're using a miniDV, DVD, flash drive, or hard-drive camcorder, the device will need a cable to connect to your computer. The type of cable you need to use (USB 2.0 or FireWire) will depend on the type of camcorder you have. For example, hard-drive camcorders use the USB 2.0 interface, while miniDVs use FireWire. If you don't have the connection you need on your computer, you can always add a PCI (Peripheral Component Interconnect) card equipped with the requisite ports (for example, USB 2.0 or FireWire) to your computer.
