TV Specialists, Inc. invented and introduced the “Wizard” – the first A-B roll digital effects systems with dual time base correlators under $10,000. The dual time base correlator, in this first generation was really a single time base corrector with a very tricky genlock circuit which allowed the two tape decks to synchronize in order to do dissolves and effects. It was shown at both the Long Beach Video Expo and the New York Video Expo.
