Digital Multi Effects (DME)
DME allows you to add three-dimensional effects such as image movement,
rotation, magnification and shrinking, as well as a wide variety of special
effects. DME is the general name for all of these effects.
You can use up to four channels as dedicated DME channels. Each channel can
be used on its own or in combination with other channels, which allows you to
create advanced effects with more complexity.
Note
To carry out DME wipes requires the BKDS-9470 DME Board Set.
Three-Dimensional Transformations
Transformation is the process of placing a video image in a three-dimensional
DME coordinate space and subjecting it to manipulations such as movement,
rotation, magnification or shrinking.
Three-dimensional coordinate space
Source coordinate space and target coordinate space
Images are placed in one of two types of coordinate space: source coordinate
space and target coordinate space.
• The source coordinate space is a three-dimensional coordinate space with
reference to the image itself. The x- and y-axes are defined parallel to the
plane of the image, and the z-axis is defined perpendicular to the plane of the
image. When you move the image, the coordinate axes also move.
• The target coordinate space is a three-dimensional coordinate space with
reference to the output monitor screen. The x- and y-axes are defined parallel
to the plane of the monitor screen, and the z-axis is defined perpendicular to
