Spill Suppressor (PB only)


    The Spill Suppressor removes traces of the key color from an image with a screen that has already been keyed out. Typically, the Spill Suppressor is used to remove key color spills from the edges of an image. Spills are caused by light reflecting off the screen and onto the subject.

    Tip iconIf you are not satisfied with the results from using the Spill Suppressor, try applying the Hue/Saturation effect to a layer after keying, and then decrease the saturation value to de-emphasize the key color. (See Hue/Saturation.)

To apply the Spill Suppressor:

  1. Select the layer and choose Effect > Keying > Spill Suppressor.
  2. Choose the color you want to suppress in one of the following ways:
    • If you have already keyed out the color with a key in the Effects Window, click the Color to Suppress eyedropper, and then click the screen color in the key's Key Color swatch.
    • In Spill Suppressor, click the Key Color swatch and choose a color from the color wheel.
  3. In the Color Accuracy menu, choose Faster to suppress blue, green, or red. Choose Better to suppress other colors, because After Effects may need to analyze the colors more carefully to produce accurate transparency. The Better option may increase rendering time.
  4. Drag the Suppression slider until the color is adequately suppressed.
