Abstract
Abstract An editing apparatus controls a plurality of video tape recorders so that a slow motion picture, a quick motion picture or a combination of the slow motion picture and the quick motion picture reproduced by the video tape recorder can be edited on a video tape. The editing apparatus includes an input keyboard to input data of a desired tape speed at first and second tape positions, a calculating circuit for calculating a tape speed at any position between said first and second positions on the basis of the input data, and a control circuit for controlling a tape speed of said video tape recorders in response to an output signal of said calculating circuit.
