Figure 7.5 Key Preview Buttons — Keyers Module (4-Keyer Shown)
KEY PV
The Key Preview feature allows you to temporarily force the program output of the selected
Keyer to the preview output of the switcher. The MLE 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.
MultiDSK keyers do not support the Key Preview feature.
SHOW ALPHA
The Show Alpha feature allows you to view the black and white alpha signal for the selected key.
This alpha signal can either be routed to the main preview output of the switcher, or to the
preview output of the selected MLE.
Note — The Show Alpha feature cannot be applied to Preset Pattern keys at this time.
• Switcher Preview Output — Press and hold the SHOW ALPHA button, for the
selected Keyer and MLE, to show the alpha for that Keyer on the main preview output of
the switcher.
• MLE Preview Output — Double-press the SHOW ALPHA button, for the selected
Keyer and MLE, to have the alpha signal for that Keyer fed out of the preview for that
MLE. The main preview output for the switcher is unaffected. This allows you to record
the alpha signal for a selected Keyer independent of the fill. The Show Alpha feature
remains active until the button is pressed again.
Key Transition Buttons
The Transition buttons (Figure 7.6) allow you to perform a dissolve transition using the Auto
Transition (AUTO TRANS) button or a cut using the Cut (CUT) button.
The rate at which the auto transition is performed is shown as the Key Rate on the Memory
System Module for the MLE, or the Global Memory System Module for the Program/Preset
MLE.
