An audio/videodisc synchronizer accepts random access frame numbers and records digital ques on one track of a magnetic tape. Other tape tracks are available and are used for recording audio or for synchronization of other videodiscs. When the digital ques are played back through the synchronizer, a videodisc player is controlled through its computer interface. As a result, by use of ordinarily available components, virtually unlimited audio is available per still video frame. The device of the present invention provides for remastering of the program audio independent of the videodisc source and thereby eliminates the need for video frames with audio to be recorded on the videodisc in the same sequential order in which they will be played, when continuous audio is required, and allows video frames to be removed or added into an existing presentation. Importantly, the present invention allows a user to fully utilize the large storage potential of videodiscs, currently 54,000 frames per side, for smaller presentations by allowing the audio source to select the video frames to be viewed. This means that one videodisc could hold hundreds or thousands of various video presentations and the user could have many audio tapes corresponding to a single videodisc.
