2. Key Modifier Section 1 (All groups)
The buttons in Key Modifier Section 1 allow you to modify the key that is currently
selected.
• Press
MATTE FILL
to fill the selected key hole with a matte color (or wash) —
instead of the key foreground video from the Key Bus . All key types except Preset
Pattern keys can be filled with matte color. Use the controls in the Matte Group to
choose the matte’s hue, luminance, saturation, and (if desired) complex wash color.
Refer to the section “
Matte Group ” on page 6–16 for matte fill and color wash
instructions.
• The
KEY MEM
(memory) function applies to Auto Select and Chroma Keys only.
This function allows you to store and recall one set of favorite adjustments per key
type.
~
For each Auto Select Key , one memory register only is provided that stores the
key’s clip and gain settings.
~ For Chroma Keys , one memory register is provided for the entire switcher.
This register stores one set of chroma key clip, gain, hue, reject and suppress
settings.
The Key Memory function is switcher-wide. This means that you can store a new
Auto Select or Chroma Key setting in one MLE, and when you enable the same
key source in a different MLE, both settings will be identical — visually and
electronically.
The
KEY MEM
button affects each key type as follows:
~ Auto Select Keys
For Auto Select Keys, the
KEY MEM
button turns on automatically when you
press
AUTO SELECT
and choose an Auto Select key source on the Key Bus .
This function recalls the key’s settings from memory, no matter where the key
is enabled on the switcher. With the button lit, clip and gain settings are locked.
If you press
KEY MEM
to turn off the light, you unlock clip and gain, allowing
you to make temporary adjustments to the linear key’s settings. Turning the
button back
on again restores the key source’s default settings from memory.
Although the default clip and gain settings were set during the switcher
installation process, you can also use the
KEY MEM
button to store new
default values for the selected linear key source. Refer to the section
“
Performing an Auto Select Key ” on page 7–22 for details.
~ Chroma Keys
For Chroma Keys, press
KEY MEM
to recall all settings from the chroma key
memory register. When you select a Chroma Key source, the
KEY MEM
button does not come on automatically. You can also use the
KEY MEM
button
to store a new set of chroma key values. Refer to the section “ Performing a
Chroma Key ” on page 7–24 for details.
• Press
MASK
to activate the Mask controls in the Effects Control group. These
controls allow you to selectively eliminate unwanted portions of a key signal,
similar to the “crop” function found on many DVEs. You can independently mask
the top, bottom, left or right edges of the key, using a box pattern. All key types
except Preset Pattern keys can be masked. Refer to the section “ Effects Control
Group ” on page 7–14 and the section “ Masking Keys ” on page 7–49 for
information and instructions.
