Names and Functions of Parts of the Control Panel
TRANS: By pressing this button, you can
check the DME channel used for DME
wipes on the M/E or PGM/PST bank.
Also, by pressing this button, then
pressing one of the DME channel
selection buttons, you can preset the
DME channel to be used when a DME
wipe is selected as the transition type
for the next transition.
When presetting the DME channel for
an independent key transition, hold
down this button, then press one of the
[KEY1] to [KEY4] buttons, turning the
two buttons on, beforehand.
b Key type selection buttons
Press one of these buttons, turning it on, to
select the desired key type.
Depending on the selected key type,
various parameters are displayed, and you
can set the values with the knobs.
LUM (luminance key): The background is
cut out according to the luminance (Y)
of the key source signal, and at the
same time the key fill signal is cut out
and then added to the background
signal.
LIN (linear key): This is a type of
luminance key with a reduced variation
in gain and a higher adjustment
precision.
CRK (chroma key): A particular hue
(usually blue) in the key source signal
is used to determine the hole to be cut
in the background and filled with the
key fill signal.
CVK (color vector key): The background
is cut out with a key source created by
adding the luminance and chrominance
components of the key signal. If the
saturation is high, this allows perfect
keying even if the luminance level is
low and the signal is not suitable for
luminance keying.
PTN (wipe pattern key): A hole is cut in
the background by a wipe pattern
selected in the transition, and this is
filled with the key fill signal.
c Key fill/key source selection buttons
AUTO SEL (selection): Use the signal
selected on the key fill bus, and the
paired key source signal. The setting of
key fill and key source pairs is carried
out in a Setup menu.
SPLIT: To use the signal selected on the
key fill bus as key fill, and a signal
separate from the signal assigned in a
pair with key fill for key source, press
this button, turning it on.
To select the signal on the key source
bus, hold down this button, and press a
button in the key 1 or key 2 row in the
cross-point control block.
To use the signal selected on the key fill bus
as key source (self keying), press the
[AUTO SEL] button and [SPLIT] button at
the same time, so that both are off.
MATTE FILL: To use a color matte from
the internal generator as key fill, press
this button, turning it on. You can
adjust the color matte using the knobs.
When this button is off, the signal
selected on the key fill bus is used as
key fill.
d Key modifier buttons
To add an edge modifier to the key, press
one of these buttons, turning it on.
Depending on the edge type selected,
parameters appear in the displays, and you
can set the values with the knobs.
KEY DROP: When drop border or shadow
is selected, turning this button on
lowers the key fill and key source
position by four or eight scan lines as
set in the key menu.
To select 4H or 8H, use the Key menu.
When the selected edge type is
“normal” and soft edge is selected or
when border, outline, or emboss is
