S03260 ABSTRACT OF THE DISCLOSURE A method and apparatus for editing video information from one or more video tapes onto a master tape, in which different video tape recorders can be used to produce the master tape, involves the storage of tracking information that was used in recording a segment at a position immediately preceding the desired editing point on the master tape, and also stores tracking information that was used in recording another segment at a position on the master tape some time prior to the segment next preceding the edit point. A difference value between the two stored tracking information signals is detected and compared with a predetermined value, and the comparison result is used to select one of the two stored tracking information signals to control the tracking during recording at the desired editing point, so that small head position detector errors will not accumulate over a number of edit points on the master tape.
