A video capture board (also called a video-capture card) transforms an analog video into its digital counterpart. Because a digital video file for even short video requires a great deal of storage space, most video capture boards equipped to perform on-the-fly data compression to reduce the file size using one of several codecs (compression/decompression standards ). Three-dimensional games have driven computer video cards offer sophisticated, ultrafast graphics processing that only a few years ago would have required a supercomputer. Most digital video camcorders can take still images as well as movies.
