Which channel relationship needs attention?

Add this view from Add scope > Quad Balance, then choose the input you want to inspect. Use the pane's i button for its in-app reading guide.

  1. Read the axis labels around the four channel-pair regions.
  2. Vivid stage lighting creates strongly colored distributions; relate them to Picture.
  3. Held-key inspection enlarges a quadrant while preserving the saved presentation.

Try it yourself.

  1. Compare the concert and a neutral studio sample.
  2. Hold a corner numpad key to inspect a quadrant, then release.
  3. Compare the same source in Vectorscope and Color Balance Plot.

Useful controls.

  • Numpad 2/4/6/8 applies 2× inspection with temporary 45-degree rotation.
  • Corner keys inspect quadrants; 5 inspects the center with current rotation.
  • Trace, references and shared regions refine inspection.

Use a known neutral subject for matching rather than assuming that the entire colored stage should balance neutrally.
