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.
bKey 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.
cKey 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
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.
dKey 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
