ABSTRACT:
A method and apparatus for editing video cassettes. The video cassette editor can be used to move a video cassette to a particular position on the tape relative to a reference point as a function of tape length expressed in units of time. The video tape editor is also capable of calculating recording speed switchover points for maximizing the recording time in standard play mode and thereby increasing the quality of the video image for the maximum amount of time.
