The V-160HD lets you create a composite with two DSK layers.

From [MENU] -> “DSK 1” or “DSK 2,” select “DSK MODE” and then select the mode using the [VALUE] knob.

• SELF KEY: This 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: Use alpha channels (areas which contain transparency data) to cut out 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.
