video fill (the source can be either an
Auto-Select key or a Self key).
2. Press and hold the AUTO SELECT
button.

key alpha.
Note:

50% and gain set to 50%.
• While holding the AUTO SELECT button to
select the key alpha, the SHIFT button stays
active when pressed. You do not have to hold
down SHIFT to access shifted sources. Press
SHIFT again to return to normal source
selection.
