Disk-assisted editing for recorded video material

摘要

A disk-assisted system for editing video tapes. Source material from video tapes is logged onto random access storage such as a hard disk drive using of a Macintosh-based computer system. At any one time, only a small portion of the tape material is stored as video frames on the computer disk. By software control, material is cached back and forth between the computer disk and the video tape. Thus editing is accomplished and an edit decision list constructed for compilation of the final video production. This provides the advantage of fast access time for editing of the material which is on the disk while allowing actual physical editing at the end of the project of the actual video tape material. The processes of logging the material onto the disk and editing the final tape are performed automatically.
