key.

After selecting the number using the rotary 2 control, move
the chroma key cursor on the preview image to the color
(blue for example) to be removed using the joystick, and
press the
key.
The numeric values of the stored color are displayed for R,
G, and B, respectively, in the menu. ("---" appears when the
color is not stored.)
The color can be stored any number of times by pressing
the
key. However, the color data is overwritten each time
it is stored.
To cancel the stored color, enter the selected number using
the numeric keys while holding down the SHIFT key.
To set the chroma key in detail
The color density and range can be specified to designate
more precise keying.
Set [SLICE] of the selected color in the range of 0 to 255
using the rotary 3 control.
The slice is set to specify the color density (saturation) in
the area to be removed. For example, if you specify blue
using the joystick, the setting value can be increased to
remove only blue darker than the specified blue.
Set [SLOPE] of the selected color in the range of 0 to 15
using the rotary 4 control.
The slope is set to specify the range (hue) of the color to
be removed. For example, if you specify blue using the
joystick, the setting value can be increased to remove only
blue closest to the specified blue.
Set [K LEVEL] (transparency level of the key) in the range
of 0 to 255 using the rotary 5 control.
NOTE
The value set with the rotary 3 control is saved for each of the
three key colors, while the value set with the rotary 5 control is
applied to all stored colors.
[COLOR CANCEL]
The appearance of color blur can be diminished in the
boundary area of the key.
