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.

Disk-assisted editing for recorded video material

A video digital signal processing and display system that allows real time processing of video images with extensive filtering and inter-pixel interpolation. The system includes a front end user and program interface supported by a personal computer, and also includes a microprocessor for controlling the system and specialized video circuitry including an image translator. The image translator performs image translation, perspective projection, scaling, rotation, border insertion, and formation of composite images. The image translator interacts with the other specialized video circuitry which includes a frame constructor, a keyer and crosspoint switches, and a frame store constructor.
