Note:
• You must include the background when performing
a DVE transition on a Chroma Key, Self Key, or
Auto-Select Key. If you do not include the
background, a dissolve transition is performed.
• Performing a DVE transition on a DVE Key without
including the background scales the transition
effect to the size of the DVE Key. This transition
does not consume an additional DVE resource.
• Performing a DVE transition on a DVE Key with the
background included does not scale the transition
effect. This transition consumes the second DVE
resource.

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 (this key type is
created when you do not specify an input for the
key alpha channel).
• 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 KM-H2500 supports 2 keys. The KM-H3000
supports 3 keys.
