2. Key Modifier Section
The buttons and knobs in the Key Modifier Section allow you to modify the Key that is
currently selected.
• Press
KEY INVERT
to invert the polarity of the selected Key signal. For example,
if a Self Key source has white letters on a black background, the white letters
normally cut the hole. When
KEY INVERT
is pressed, the polarity of the signal is
reversed and the black background cuts the hole. This function is often used to Key
black text that is printed on a white background.
• Press
MASK
to activate the Mask controls. These controls allow you to selectively
eliminate unwanted portions of a Key signal, similar to the “crop” function found
on many DVEs. Using an adjustable box pattern, you can size and position the mask
to hide the top, bottom, left or right edges of the Key.
In addition, the
REV/LEARN
button in the Effects Control Group can be used to
invert the mask. All Key types except Preset Pattern Keys and Squeeze & Tease
MD boxes can be masked.
• Press
FLY KEY
to enable or disable the Squeeze & Tease MD or Squeeze & Tease
MD WARP function, allowing you to apply 3-D DVE effects to any of the four Key
types. If the Squeeze & Tease MD option is installed, the
FLY KEY
button will
light automatically when
PST PATT
is pressed, but must be pressed manually to fly
a
CHROMA KEY
,
AUTO SELECT
or
SELF KEY
.
Once enabled, you can control the size, horizontal and vertical position, and rotation
of the flying Key. The
FLY KEY
button will not light if one of the options is not
installed. If you have the Squeeze & Tease MD option installed, refer to the section
“ Operational Overview ” on page 12-2 for instructions.
• Press
MATTE FILL
to fill the selected Key hole with a matte color, instead of the
Key foreground video from the Key Bus . Use the controls in the Mattes Group to
choose the hue, luminance, and saturation of the matte. Refer to the section “ Mattes
Group ” on page 6-10 for more information on matte fill.
• The
HUE/TRANSP
knob has two functions.
~ With a Chroma Key, the
Hue/Transp
knob is used to select the color that you
want to Key out, this is essentially the color to be replaced by the background
video. The knob rotates through the full 360-degree color spectrum.
~ If you are setting up a Self Key or Auto Select Key , the
HUE/TRANSP
knob
is used to adjust the transparency of the Key.
• Use the
CLIP
knob to adjust the luminance or threshold level of the Key. Only the
areas of the source video that are higher than the setting of the threshold will cut a
hole in the background video.
Note
All Key types can be inverted, except for Squeeze & Tease MD boxes.
Note The Squeeze & Tease MD option has not yet been implemented.

Note All Key types except Preset Pattern Keys can be filled with Matte
Color.
