The following Key Menu functions are provided:
•Key Type — displays the type of key, currently fixed as a “Luma” key.
•Invert Mode — enables you to invert the key signal.
•Clip — adjusts the threshold of the video that electronically “cuts” into the background image. A hole will be cut into the background 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 sensitivity of the keyer, enabling you to change the sharpness of the keyed image. Gain only affects the key hole, as set by the clip. Adjustment range is 0 to 1023.99.
•Opacity — enables you to adjust the opacity of the keyed image, from fully opaque to fully transparent. Adjustment range is 0 to 1024.
