to convert incoming video signals to a standard digital video format, and additional circuitry to convey the resulting digital video to local storage or to circuitry outside the video capture device, or both. Depending on the device, the resulting video stream may be conveyed to external circuitry

PCI capture cards offered 30 frames per second. These cards could also handle capturing VHS tapes etc. but VHS image quality was poor so many adopted new video cameras until eventually digital cameras surfaced. Capturing video from digital cameras delivered excellent results above DVD quality.

Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a dedicated

package. One early card was a sandwich of two cards as early processors needed more logic to even get up to 15 frames per second.
