The Omega Verksted Video Synth is a modular video synthesizer system. It is connected to a matrix video switch which can route video signals around the room. The rack it is housed in ("The Sofa Rack"), is also intended as a platform for people to experiment with modular synths in general. Currently 3x84HP of eurorack space is installed, fitted with eurorack power supplies for +/-12V providing a total of 18A for each channel.

Analog Video Introduction (WIP)

Analog video was the standard before digital video formats were developed. There are many different standards of analog video. Most are conceptually similar, but they have varying numbers of signal wires, as well as different modulations. Some are backwards compatible and/or semi-cross-compatible. Some common standards:

  • Composite Video (see below)
  • S-Video (Successor to composite where black-and-white and coloring signals are separated on two wires)
  • YPbPr Component Video
  • RGB Component Video
  • VGA

The OV video synth uses mainly composite video, but also some YPbPr, and some VGA externally.


Composite Video

Composite video is a video format where the video information required to recreate a color picture, as well as line and frame synchronization pulses, is encoded on a single wire. The color video signal is a linear combination of the luminance of the picture and a modulated subcarrier which carries the chrominance or color information, a combination of hue and saturation.


Modules

Input + Output (Modified LZX)

Decodes and encodes composite video. Based on:

Cadet IV Dual Ramp Generator (LZX)


Cadet VIII Hard Key Generator (LZX)


4x3 Matrix Mixer (Reverse Landfill)

Matrix mixer that outputs three signals generated from weighted averages of four input signals. Weights are determined with the knobs.

Intended as an RGB mixer towards the end of the signal chain before the composite encoder.
