The DSK Adjustment Menu enables you to adjust key and fill parameters for the DSK source. The following functions are provided:

•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).

~Matte — fills the hole with a matte color, which can then be adjusted with the DSK Matte Adjustment Menu. Refer to the “DSK Matte Adjustment Menu“ section on page 79 for details.

•Press {INPUT SETUP} to display the BG/DSK Input Setup Menu. Refer to the “Background/DSK Input Setup Menu Functions” section on page 76 for details.
