Keying Overview
Keying allows you to insert portions of one scene
into another. Keys appear as overlays over the
background image.
The switcher supports the following key types:
• Auto-Select Key — Key alpha (transparency) is
provided on one input and key fill video is
provided on a second input (character generators
and graphics systems typically provide fill and
alpha on separate channels).
• Self Key — Key transparency is derived from the
luminance of the key fill video .
• Chroma Key — A user defined color hue is
selected for transparency (such as blue or
green-screen applications).
• DVE Key — The video image can be scaled,
cropped and freely positioned on the screen.
Borders and other effects may be used to enhance
the key appearance.
The CrossOver 16 supports 3 keys.
