LZX Visionary: Vector Rescanning Experiments

This clip uses the LZX Visionary modular video synthesizer as a driving source for a vector display instead of a television (in this case a standard cathode-ray oscilloscope). Modules used include two Video Waveform Generators to create horizontal and vertical control ramps (for X & Y inputs), Video Sync Generator to DC restore external video (for Z input) and provide synchronization signals to the control ramps, and Triple Video Fader & Key Generator to crossfade between control ramps and external video going to X & Y inputs of the oscilloscope. A third oscillator for modulation controls the crossfader as well. Video source is Casablanca (1942) played back from a DVD player. Oscilloscope is filmed with Canon HFS100 camera. Saturation, brightness, and contrast adjustments are made in software to view the output better -- much better results could be achieved with further fine tuning of the display and camera. This type of effect is similar to those achievable by historical devices like the Scanimate and Rutt-Etra machines.
