1. Basic operations
1-5. DSK (downstream key)
Characters or other images can be combined with the
background image.
1-5-1. Selecting the DSK type
1
Press the
d
button to light its indicator, and display the
DSK menu.
2
Use [F1] to display the DSK sub menu.
3
Use [F2] to select the Type item.
Lum
(luminance key/
self key)
This is for creating the key signals from
the luminance component of the key fill
signal.
Linear
(linear key/
EXT key)
This is for creating the key signals from
the luminance component of the key
source signal.
It is used when the key source signal and
key fill signal are different.
Since the luminance key is operated as a self key, the
key fill signals are used as the key source signals.
When the luminance key has been selected as the
downstream key type, the key signals will remain
unchanged even when the key source signals are
switched.
When using the linear key, use material with a black
background and white characters or shape to be
combined by the key as the key source signal.
Material which is not black and white may not be
combined clearly.
Material with a white background and black characters,
etc. can be reversed using the key invert function for
use.
4
When the luminance key has been selected, the
chroma components can be contained in the key signals
generated in view of the fact that it is used as a self key.
(This is not applied to the linear key.)
Use [F3] to select the setting using the Lum Key item.
Chroma On
In addition to the luminance components,
the chroma components are also factored in
when generating the key signals.
Use this setting if colors with low luminance
components are used for the key signals
(when, for instance, blue characters are to be
removed).
Chroma Off
The key signals are generated only from the
luminance components.
5
Use [F4] to select the fill type using the Fill item.
Bus
The bus signal is used for the key fill signal.
Matte
The internal fill matte is used for the key fill
signal.
Setting the fill matte color
1
On the DSK menu, use [F1] to display the Fill Matte sub
menu.
2
Use [F2], [F3] and [F4] to adjust the Hue, Sat and Lum
of the fill matte.
w
To call the preset color
Use [F5] to select the preset color using the Load item,
and press the [F5].
When [F5] is pressed, what has been set so far is
canceled and replaced with the preset color values.
To save the values that were set before calling the preset
color, refer to “1-10. Memory”.
