  3. In the Type area, select Alpha.
  4. Use the Video Format knob to select the video format of the input video signal on the selected input source.
  5. Press Auto Key Setup.
  6. Use the Source knob to select the input source that has the fill of the auto key you want to set up.
  7. Use the Alpha knob to select the input source that has the alpha of the auto key you want to set up.

    • Unshaped — switcher performs a multiplicative key. The key alpha cuts a hole based on the gradient values of the alpha. Shades of gray are translated into transparency levels, giving the key a soft edge. Unshaped key alphas can also be considered true linear alphas.
    • Shaped — switcher perform an additive key. With shaped keys, the key alpha cuts a hole based on the monochrome value of the alpha. Shades of gray are translated into either white or black, giving the key a hard edge. Shaped Key alphas are sometimes used with Character Generators to cut very precise holes for the fill.
