Abstract
A system for digital video editing and publishing is disclosed including a video capture unit, a video compression unit, and video decompression unit coupled to a host computer having video editing capabilities. This system allows video editing to occur using intraframe-only compressed video data. The edited video data can then be decompressed and recompressed to provide compressed data, which is compressed using both interframe and intraframe operations, usable for publication in a removal storage medium, such as a compact disk or a data network.
