In digital video, a type of digitizing board added to a computer which, when a VCR, video camera, videodisc player, or other such device is attached, allows for video and audio signals to be captured and digitized, enabling digital editing to be performed. Frame grabbers can capture a single frame of a video, usually at very high resolution and with a color depth of 24 bits per pixel. A frame grabber can also capture the entire video, at a resolution, size, and frame rate dependent upon the power of the processor and the amount of RAM possessed by the system. In this latter sense, it is more often referred to as a video capture board.
