Menu List
7: DSK
Menu item Value (Bold: default) Explanation
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 dierent background video as a composite.
EXTERNAL KEY
Sets the key signal (the shape to be cut out) and the ll video (the video to be
composited) separately (external key). This uses the key signal to cut out the ll
video and superimpose it on the background video to create the composite.
DSK SOURCE
HDMI 1–8, STILL 1–8
* When DSK MODE = SELF KEY
Select the source of the logo or image that you want to superimpose.
STILL 1–8
* When DSK MODE = ALPHA KEY
KEY SOURCE (*3) HDMI 1–8, STILL 1–8 Sets the video to use as the key signal (the shape to be cut out).
FILL SOURCE (*3) HDMI 1–8, STILL 1–8 Species the ll video (the video to be composited) source.
DSK TYPE (*4)
Species 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 specied key color transparent according to hue.
DSK LEVEL (*4) 0–64–255 Adjusts the degree of extraction (transparency) for the key.
DSK GAIN (*4) 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).
CHROMA
Make detailed settings for chroma key.
* This can be set if “DSK TYPE” is “CHROMA.”
COLOR GREEN, BLUE
Sets green or blue as the key color (the color to be removed).
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 -30–0–30 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
If this is “ON,” a sampling marker (cross cursor) is shown on the preview output
video for you to sample (detect) the key color.
When you execute sampling, the setting automatically turns “OFF.”
POSITION H -50–0–50% Adjusts the horizontal position of the sampling marker.
POSITION V -50–0–50% Adjusts the vertical position of the sampling marker.
SAMPLING EXECUTE EXEC
Executes key color sampling.
The “HUE WIDTH,” “HUE FINE,” “SATURATION WIDTH,” and “SATURATION FINE” settings
are adjusted automatically.
FILL TYPE BUS, MATTE
If this is “MATTE,” the superimposed logo or video is lled-in with the specied color
when using key compositing.
The ll-in color is specied by “MATTE COLOR” listed below.
MATTE COLOR
WHITE, YELLOW, CYAN, GREEN,
MAGENTA, RED, BLUE, BLACK
Species the color used when lling-in the superimposed logo or video.
* This is valid when “FILL TYPE” is set to “MATTE.”
EDGE TYPE
OFF, BORDER, DROP, SHADOW,
OUTLINE
Species the type of edge applied to the superimposed logo or video.
EDGE COLOR
WHITE, YELLOW, CYAN, GREEN,
MAGENTA, RED, BLUE, BLACK
Species the color of the edge applied to the superimposed logo or video.
EDGE WIDTH 0–3–14 Species the width of the edge applied to the superimposed logo or video.
(*3) This can be set if “DSK MODE” is “EXTERNAL KEY.”
(*4) This can be set if “DSK MODE” is “SELF KEY.”
