To Apply a Proc Amp to a Video Source

A Processing Amplifier (Proc Amp) applies color correction in the HSL (Y-Cr-Cb) color space for switcher sources.

  1. Click Navigation Menu > Configuration > ProcAmps > ProcAmp.
  2. Click the ProcAmps and Color Correctors button and select the video input or output that you want to apply the Proc Amp to.
    Tip: If correction has already been applied (ON), press Reset to return the Proc Amp and Color Correctors to the default values.
  3. Click an Enable button to turn the Proc Amp on (On) for the selected video input or output.


  4. Use the sliders to adjust the video source.
    • Chroma Gain — adjust the chrominance gain only.
    • Luma Gain — adjust the luminance gain only.
    • Hue Rotation — adjust the Hue. Increasing the Hue Rotation turns the color wheel clockwise, and decreasing the Hue Rotation turns the color wheel counter-clockwise.
    • Black Level — adjust the black level. Black level acts as a luminance offset.
    • Gamma — adjust the luminance gamma value.
    • Gamma Offset — adjust the luminance gamma offset.
    • Cr Gain — adjust the gain of the Cr (red color difference).
    • Cr Offset — adjust the offset of the Cr.
    • Cb Gain — adjust the gain of the Cb (blue color difference).
    • Cb Offset — adjust the offset of the Cb.
