DVE Keys
The DVE key allows you to apply digital video effects,
such as scale, crop, aspect ratio, position, and border to
video image or another key type. When the DVE is
applied to another key type, it is said to be flying (Fly
Key).
Keep the following in mind when working with a Fly
Key:
•
The Fly Key feature consumes a single DVE
channel for self keys and chroma keys, but two
DVE channels for an auto select key.
•
The Fly Key feature is not available when the
switcher is in Standard mode.
•
The Fly Key feature cannot be applied to a DVE
key.
•
The Key Invert feature is not available for a Fly
Key.
•
The self key Fly Key can be used with all
MultiScreen layouts. The auto select key Fly Key
can only be used with the Dual Vert or Dual Horiz
MultiScreen layouts.
•
A chroma key should be initialized and adjusted
before the DVE (Fly Key) is applied to it.
