The external key automatically uses Key 3 for the Cut channel, and Key 4 for the Fill
channel. Although using the external key feature disables the use of Key 3, you can

the use of Key 3. When the external keyer is in use, all the Keyer Modifiers discussed in
section 4 are still available.

1.
Select the
[Key 4 Select]
PixButton in the Destinations Row, it will illuminate
orange, as shown below.
2.
Select the
[CG Fill]
button using the Sources Row.
The Device Control-B PixPad will change, showing the Key 4 Modifiers and the
display will change showing Clip and Gain adjustments, as shown below.

To preview the external keyer over your background video, in ME 1 or ME 2,
select the
[Key 4 Transition]
button.
