Acuity® Configuration

These buttons can be assigned to various functions or buses on the switcher. The default assignments are labelled on the buttons.



Note: The exact buttons assignments and placement vary depending on the size of your control panel.
Button Function

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.
MATTE FILL Fill the selected keyer with a matte color.
BORD 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.
AUX Press and hold the AUX button and use the source buttons on the keyer row to select the aux you want to use.
SHOW ALPHA 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 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.
