The DSK Adjustment Menu enables you to adjust key and fill parameters for the DSK

• Key Type — displays the type of DSK key, currently fixed as a “Luma” key.
• Invert Mode — enables you to invert the DSK signal.
• Clip — adjusts the threshold of the video that “cuts” into the background. A hole
will be cut anywhere that foreground luminance is greater than the clip level. The
hole is then filled with the
Fill Source. Adjustment range is 0 to 1023.
• Gain — adjusts the keyer sensitivity, enabling you to change the key’s sharpness.
Gain only affects the key hole. Adjustment range is 0 to 1023.99.
• Opacity — enables you to adjust the key’s opacity, from fully opaque to fully
transparent. Adjustment range is 0 to 1024.
• Fill Source — determines the video that fills the key hole:
~ Self — fills the hole with the key source video itself (e.g., video from a
character generator).
