Menu List

8: DSK
Menu item Value (bold text: default value) Explanation
DSK 1, 2 These settings configure the DSK composite details for each DSK layer.
DSK MODE
Sets the DSK mode.
SELF KEY
Uses the luminance key (brightness) and chroma key (color) to cut out the video image
and create a composite by overlaying the video on a background video.
ALPHA KEY
Uses alpha channels (areas which contain transparency data) to cut out still images and
place them against different background video as a composite.
EXTERNAL KEY
Sets the key signal (the shape to be cut out) and the fill video (the video to be composited)
separately (external key). This uses the key signal to cut out the fill video and superimpose
it on the background video to create the composite.
DSK SOURCE
HDMI 1– 7 –8, SDI 1–8, STILL 1–16
* When DSK MODE = SELF KEY
Specifies the source of the caption or video that is overlaid.
STILL 1 –16
* When DSK MODE = ALPHA KEY
KEY SOURCE (*5) HDMI 1– 7 –8, SDI 1–8, STILL 1–16 Sets the video to use as the key signal (the shape to be cut out).
FILL SOURCE (*5) HDMI 1– 7 –8, SDI 1–8, STILL 1–16 Specifies the fill video (the video to be composited) source.
DSK TYPE ( *6)
Specifies the DSK type used during DSK composition.
LUMINANCE-WHITE
Composite using luminance key.
Makes white portions transparent according to brightness.
LUMINANCE-BLACK
Composite using luminance key.
Makes black portions transparent according to brightness.
CHROMA
Composite using chroma key.
Makes the specified key color transparent according to hue.
DSK LEVEL ( *6) 0– 64 –255 Adjusts the degree of extraction (transparency) for the key.
DSK GAIN ( *6) 0 –255 Adjusts the degree of edge blur (semi-transmissive region) for the key.
MIX LEVEL 0– 255 Adjusts the key’s overall density (output level).
COPY SETTING FROM DSK 2
( or DSK 1)
EXEC Copies the other DSK settings.
SWAP SETTING WITH DSK 2
( or DSK 1)
EXEC Exchanges the settings of DSK 1 and DSK 2.
CHROMA ( *7) Make detailed settings for chroma key.
COLOR GREEN, BLUE
Specifies green or blue as the key color. If you want a color other than green or blue to turn
transparent, use “SAMPLING MARKER” to specify the key color.
HUE WIDTH -30– 0 –30 Adjusts the hue width for the key color.
HUE FINE 0– 240 –360 Adjusts the center position of the hue for the key color.
SATURATION WIDTH -128– 0 –127 Adjusts the saturation width for the key color.
SATURATION FINE 0 –255 Adjusts the center position of saturation for the key color.
SAMPLING MARKER OFF , ON
When this is “ON,” a sampling marker ( ) is shown for you to sample (detect) the key
color. When you execute sampling, the setting automatically turns “OFF.”
POSITION H ( *8) -50– 0 –50% Adjusts the horizontal position of the sampling marker.
POSITION V ( *8) -50– 0 –50% Adjusts the vertical position of the sampling marker.
SAMPLING EXECUTE ( *8) EXEC
Executes key color sampling.
The “HUE WIDTH,” “HUE FINE,” “SATURATION WIDTH,” and “SATURATION FINE” settings are
adjusted automatically.
FILL TYPE
Sets the fill material type (the video used for key compositing).
BUS Uses the video specified in “DSK SOURCE.”
MATTE
Uses the internal color matte (a single-color image). The superimposed caption or video is
filled in with the matte color. Specify the matte color using the “MATTE COLOR” setting below.
MATTE COLOR ( *9)
WHITE, YELLOW, CYAN, GREEN,
MAGENTA, RED , BLUE, BLACK
Specifies the matte color.
EDGE TYPE
OFF , BORDER, DROP, SHADOW,
OUTLINE
Specifies the type of edge applied to the superimposed caption or video.
EDGE COLOR
WHITE, YELLOW, CYAN, GREEN,
MAGENTA, RED, BLUE, BLACK
Specifies the color of the edge applied to the superimposed caption or video.
EDGE WIDTH 0– 3 –14 Specifies the width of the edge applied to the superimposed caption or video.
(*5) This can be set if “DSK MODE” is “EXTERNAL KEY.”
(*6) This can be set if “DSK MODE” is “SELF KEY.”
(*7) This can be set if “KEY TYPE” is “CHROMA.”
(*8) This can be set if “SAMPLING MARKER” is “ON.”
(*9) This can be set if “FILL TYPE” is “MATTE.”
