  3. Select the blend mode from the Blend Mode box.
    Select: To:
    Blend Use subtractive blending.
    Additive Use additive blending. Select this option if the front clip has a black background, as with a computer-generated image. This option eliminates the black fringe at the edge of the front image.
    FrontMin Prevent loss of detail from the front image. For example, if the front clip is a human model, this option prevents losing details such as hair in the composite clip.
  4. You can use the Front and Back fields to increase or decrease the luminance of the front and back clips. The values specify the gain for the clips. Quick Composite multiplies the luminance values in the clips by the gain values you set. The resulting luminance values are clipped at the maximum and minimum values of 255 (white) and 0 (black), respectively.

    Gain is expressed as a percentage value. The default value of 100% has no effect on the image since the luminance values are multiplied by 1. To increase the gain, set the value above 100%. To decrease the gain, set the value below 100%.

  5. Enable Invert Matte to invert the matte, if necessary.
  6. Select the front, back, and matte clips.
  7. Select the destination.

    The composite clip appears on the destination reel.
