  • Patent number: 4754342
    Abstract: A virtual memory system for a video editor is disclosed which permits edited material from discrete takes to be electronically spliced in real time to form edited scenes. Typically, a plurality of cameras take film of originally acted scenes, either simultaneously from different angles or sequentially of differing takes of the same scene material replayed by skilled film actors. The film material is thereafter recorded from all uncut takes to a random access memory, preferably a DRAW laser video disk. An intelligent interface--preferably a microprocessor--connects at least two and preferably three laser disk heads for reading the video frames of the same uncut takes. Each disk head is provided with and reads the identical disk material containing identical unedited takes. An intelligent interface addresses a video disk head to randomly access the uncut takes and cause playing at controlled speeds forwardly, backwardly or still frame.
