Color Correction

Color correction is performed by either Processing Amplifiers (Proc Amps) in the HSL (Y-Cr-Cb) color space or by RGB Color Correctors in the RGB color space. Both Proc Amps and RGB Color Correctors allow you to apply color correction to video sources on the fly to input video signals, entire buses, or aux bus outputs.

  • Input Based Correction — color correction is applied to the video input regardless of which ME or Aux Bus it is selected on. Input-based color correction is not stored in switcher memories. Only supported on the MultiProcessor Input board.
  • ME Input Based Correction — color correction is applied to all the video inputs to the ME. Not supported on the MultiProcessor Input.
  • ME Bus Based Correction — color correction is applied to the output of the assigned bus. Unlike the other color correction types, bus-based color correction is stored and recalled with memories. This allows you to include a color correction element as part of an effects dissolve.
  • Aux Bus Based Correction — color correction is applied to the output of an Aux Bus. Like input-based color correction, Aux Bus color correction is not stored in switcher memories.

Color correction is additive, allowing you to apply any combination of Proc Amp and RGB Color Corrector based adjustment to a video signal on the input, as well as on the bus. If multiple color corrections are applied, the input-based correction is applied first, and the bus-based correction is applied after that.
