Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a digital video stream, or more often, simply video stream. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both.
Early 16-bit ISA capture cards emerged in the early 90s. These cards were supported by VIDCAP as part of the Video for Windows 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.
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.
