Modifications to Videotape Recording Equipment to Provide an Improved Method of Editing 1/2-Inch Recordings
By modifying a pair of Sony AV3650 videotape recorders (VTRs), to operate synchronously in all modes and extending their capabilities beyond the normal record and playback functions, it has been possible to develop a system for editing videotape and thus produce low-cost video programs rapidly and of a quality not appreciably less than that obtainable with professional equipment. Among the features implemented are: single-switch operation of both machines; a driven reverse mode with positive tape take-up; a device eliminating double sound recording at the edit point; use of a number of time-delay relays automated operation; an audio dub system for re-recording sound without affecting the picture; and a system for superimposing titles. Additional improvements such as replacing the time-delay relays with electronic switching are possible.
