Video recording in digital form. In order to edit video in the computer or to embed video clips into multimedia documents, a video source must originate from a digital camera or be converted to digital. Frames from analog video cameras and VCRs are converted into digital frames (bitmaps) using frame grabbers or similar devices attached to a computer.
Uncompressed digital video signals require huge amounts of storage, and high-ratio real-time compression schemes, such as MPEG, are essential for handling digital video in today's computers. See D1, MPEG, DVD, digital nonlinear editing and DTV.
