Keyers Module

The keyers module is used to assign key types, set up key modifiers, and perform independent key transitions.

Table 1. Keyers Module Button Functions

Button	Function
SEL	Selects the keyer that the module is assigned to.
AUTO SELECT	Assign the selected keyer as an auto select key.
SELF KEY	Assign the selected keyer as self key.
PST PATT	Assign the selected keyer as preset pattern key.
CHROMA KEY	Assign the selected keyer as a chroma key.
MATTE FILL	Allows you to fill the selected keyer with a matte color.
KEY MEM	Applies to auto select and chroma keys to provide a single memory register for storing key settings. Key memories are stored for the key source, so that when you store a key memory in one ME, that key memory is used when you select that same key source on any ME. The KEY MEM button turns on automatically when an auto select key is selected, indicating that the key memory for the key source is being used. If the key source has not been set up with a proper alpha, the KEY MEM button will not light.
KEY INV	Reverses the polarity of the key alpha. For example, if a self key, such as a title camera, has white letters on a black background, the white letters will normally cut the key hole. When the key invert feature is used, the polarity of the key is inverted so that black lettering is used to cut the hole.
MASK	Allows you to apply a mask to the selected keyer.
BORDER	Allows you to apply a border to the selected keyer. When pressed, the border menu is displayed, and the last selected border is applied. Press the button again to turn the border off.
2D DVE	Allows you to apply 2D DVE resources to the selected keyer.
3D DVE	Allows you to apply 3D DVE resources to the selected keyer.
CHNL MGMT	Allows you to go directly to the channel management menus. The CHNL MGMT button lights to indicate if multiple DVE channels are being used by the selected keyer.
SHOW ALPHA	Allows you to view the black and white alpha signal for the selected keyer. This alpha signal can either be routed to the main preview output of the switcher, or to the preview output of the selected ME. Press and hold the SHOW ALPHA button, for the selected keyer and ME, to show the alpha for that keyer on the preview output of the switcher, or double-press the SHOW ALPHA button to lock it on until the button is pressed again. This allows you to record the alpha signal for a selected keyer independent of the fill.
KEY PV	Allows you to temporarily force the program output of the selected keyer to the preview output of the switcher. The ME remains in the key preview state for as long as you hold the KEY PV button, and returns to normal as soon as you release the button. You can also double-press the KEY PV button to latch the ME in the key preview state until the button is double-pressed again.
