a process of transforming a video (e.g., NTSC) image into a computer (digitized) image. Video capturing options are reviewed in
New Media, March 24, 1997, pp. 58-70. The process entails adding hardware and software designed to transform an analog (TV) image, say from a videotape, into a digital computer image. Usually a video capture board must be installed that is compatible with the bus of the computer. For example, a PC generally has an ISA, EISA, or MCA bus that in turn requires a compatible video capture board inside the computer. Video boards also enable computer users to view videotape or television images "on-the-fly" without necessarily capturing the images into computer files. Video capture boards vary greatly in price and quality. What is best for a given computer depends a great deal upon the amount of RAM, video RAM, graphics adapter, screen resolution, color depth, and speed of the computer. More recent comparisons are provided by
Doyle (1994a) and
(1994b). In particular, Windows users should not purchase or install a video capture board before reading
Doyle (1994b). He provides excellent advice on things to do before installing a Windows video board along with comparisons of alternative hardware options. Price is not currently a good indicator of quality and features. (See also
