Using the Color Effect to Prepare a High-Contrast Image
This section describes how to enhance high-contrast images for use in creating Matte Key effects.
Color Effect icon
To create a high-contrast image from available footage:
1.  Apply the Color Effect to the clip, and open the Effect Editor.
2.  Drag the Clip slider under Luma Adjust to 255.
3.  Drag the Sat (saturation) slider under Chroma Adjust to –100 to remove all color saturation from the image.
4.  Adjust the Cont (contrast) and Bright (brightness) sliders under Luma Adjust until you achieve the right degree of contrast.
Black portions of the high-contrast image will be transparent, and white portions will be opaque. To switch the order, click Invert Key in the Foreground parameter category of the Matte Key effect. For more information, see Foreground.
  You can also import a graphic image with an alpha channel and use it as a Matte Key effect. See Editing with Imported Matte Key Clips.
