6 Key snapshot buttons
Use these for saving and recalling separate
snapshots for the keyers.
For example, to save the key 1 settings,
with the KEY 1 button of the keyer
delegation buttons lit, hold down the
SNAPSHOT button in the FlexiPad and
press one of the key snapshot buttons (1 to
4). This saves all the key 1 settings except
the key on/off state as a snapshot in the
corresponding register. When a chroma
key is set, the settings are saved. To recall
a saved snapshot, press the corresponding
key snapshot button.
7 Edge type selection buttons
Press one of these buttons, turning it on, to
apply a particular modification to the key
edge.
BORD (border): Apply a border around
the key.
DROP BORD: Apply a border in
specified directions (for example
below and to the right or below and to
the left) around the key.
SHDW (shadow): Add a shadow to the
key in specified directions (for
example below and to the right or
below and to the left).
OUTLINE: Use the key outline function.
• When you apply a border, drop border or
shadow, you can select the edge fill
signal to be inserted in this area, using
either the dedicated color matte
generator, or a signal selected on the
utility bus.
• When you use the outline function, you
can use the signal selected on the key fill
bus for the edge fill.
You can also adjust the width, position,
softness and density of the edge portion.
8 Key parameter setting knobs and
displays
Turning the knobs allows you to change
various key parameters. The display
below each knob shows the initial letter of
the parameter name and its value (a
maximum of three digits including a minus
sign).
Display Meaning
C–10 Clip value is –10.
D100 Density value is 100.
9 PROC (processed) KEY button
When the switcher system has a DME-
7000 or other DME unit connected,
pressing this button, turning it on, allows
you to use the processed key function.
When the processed key function is
enabled, before combination with the
background, the key fill and key source
signals produced by the switcher keyer
(with borders, shadows and other
processing already effected) are output to
the DME from the switcher auxiliary
buses. These signals are subjected to
DME processing to add extra effects, and
then returned to the switcher. Finally the
signals returned from the DME undergo
further processing and are then combined
with the background.
Since the same keyer is used both for the
initial processing and for the processing of
the return signals from the DME, you can
use both keyers on an M/E bank
simultaneously, for greater efficiency.
