6: DSK
Menu item Value (bold text: default value) Explanation
DSK 1, 2 These settings configure the DSK composite details for each DSK layer.
Jump To Setup Enter Jumps to the setup screen.
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 1–6, SDI 1–6, Still 1–2 –16,
V.Player, Input 1–8
* When DSK Mode = Self Key
Specifies the source of the caption or video that is overlaid.
Still 1 – 2 –16
* When DSK Mode = Alpha Key

DSK Level (*5) 0– 64 –255 Adjusts the degree of extraction (transparency) for the key.
DSK Gain (*5) 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 (*6) Make detailed settings for chroma key.
Color Green, Blue

to turn transparent, use “Sampling Marker Mode” 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.
Fill Type
Sets the fill material type (the video used for key compositing).
Bus Uses the video specified in “DSK Source”.
Matte
