ABSTRACT:
A video editing system uses apparatus for connection with a video playback machine (first VCR) and a dub video recorder, (second VCR). The apparatus includes tone generator circuitry for generating an edit tone to be recorded upon an audio track of a color master video tape which has been preselected for edit duplication. Control circuits allow selectively supplying the edit tone to the first VCR for recording upon the audio track to differentiate selected from unselected portions of the video track of the tape. Tone decoder circuits decode the recorded edit tone upon playback of the master tape. Circuits control starting and pausing of the second VCR in response to the decoded presence or absence of the recorded edit tone. Accordingly, the second VCR when connected to the first VCR produces an edited first copy video tape by duplication only of the selected portions of the master video tape. A video monitor is used for receiving and viewing the video signals from the playback machine, and control circuitry responds to decoding of the edit tone for deleting color from the monitor during playback of the unselected tape portions. Circuitry may be included for causing diminished audio volume during playback of the unselected portions. A process of preparing the color video master for self-editing by use of such apparatus also is disclosed.
