This hardware peripheral transfers video content from analog camcorders or
VCRs into your computer. There are many styles of video capture devices
including the Peripheral Component Interface (PCI), Universal Serial Bus (USB)
video capture device or general capture cards.
Depending on the video card,
some will have special Audio/Video (A/V) In and Out ports. Other cards will
come with S-Video and Composite ports (designed for receiving video content)
which will require you to plug the audio cable directly into your audio card.
Refer to your sound
card's user guide for more details. Some devices serve as a basic
capture card for video content incorporating the S-Video and Composite ports.
