Advanced Alpha Compositor

Depth is an illusion in the world of analog video, and Marble Index is the master of tricks. Unlike standard video mixers, which can fade and key between two sources, Marble Index has three layers. With 75 analog switches and 6 wideband faders within its depths, it is our most ambitious compositing module yet.

  • Triple Layer RGB Video Mixing. Most video mixers and broadcast consoles are structured around a dual channel structure. Marble Index takes a different approach: three layers stacked on top of each other, like pancakes!
  • A Vast World of Blending Modes. No features have been spared when it comes to the feature set of each compositing operation. Each RGB input channel includes two different inversion modes, variable color offsets, and analog effects like solarization.
  • Video Rate Voltage Control. The transitions between the three layers can be controlled with oscillators or images at video rate speeds, punching windows through the composition at varying depths.
