Color Correction
You can adjust the colors in a video image using the Color Correct effect.
For a quick color correction, just use the White Balance parameter. For a
complete color correction, use the parameters in this order for best results:
• Black Balance
• White Balance
• White Clip
• Gamma Balance
You can adjust colors individually using the dials or automatically. To adjust a
dial, click the dial and drag right to increase the value or drag left to decrease
the value. Double-click a dial to reset it to 0.
You can also make adjustments entering a value in the box below a dial or by
clicking the up and down spin controls beside a value box.
To use automatic color correction:
1. Click a parameter button for the parameter you want to adjust.
Select from White Balance, White Clip, Black Balance, or Gamma Balance.
2. Using the eyedropper on the video image, drag a box around an area that
represents the best color for the parameter you’re adjusting.
For example, select the “whitest” area if you are adjusting White Balance.
