Keys

A key is an effect in which a part of the background image
is replaced by an image or superimposed text. The signal
determining how the background is cut out is termed "key
source," and the signal that replaces the cut-out part is
Independent key transition
type: wipe
termed "key fill." The system component responsible for
processing a key is referred to as a keyer.
Each switcher bank has eight keyers, each providing the
same functionality.
On each switcher bank, you can use the following key
types (methods of processing the key source).
• Luminance key
• Linear key
• Color vector key
• Chroma key
• Wipe pattern key
• Key wipe pattern key
Key modifiers
You can apply borders and other modifiers to the edge of
the key image.
Masks
A mask allows a part of the image to be replaced by the
background or a key. To prevent unwanted holes in the
background, or if a key is not the desired shape, you can
correct this with a mask.
Resizer
This function allows you to apply effects, similar to a
DME, such as zoom, movement, or aspect ratio change to
a part of a created key. You can use the following
operations.
• Two-dimensional transform of a key
• Rotation of keys
• Resizer interpolation settings
• Resizer crop/border settings
• Resizer effect settings (wide key border, drop shadow,
edge enhancement, mosaic, defocus, mask)
For details, see "Keys" (page 89).

Wipes

A wipe is a transition from the current video stream to a
new video stream, using a wipe pattern.
Changing the background by means of a wipe is referred to
as a "background wipe," and inserting or deleting a key
with a wipe is termed a "key wipe."
There are two types of wipe: those that can be selected in
a common transition, and those that can be selected in an
independent key transition.
The patterns that can be used for a wipe are as follows.
• Standard wipe patterns
• Enhanced wipes
• Rotary wipes
• Mosaic wipe pattern
