• 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 the plane of the monitor screen. The
coordinates do not move even if the image moves.
Source coordinate
space
For example, as shown in the following figure, the image
moves in a different direction when you move it along the
X-axis of the source coordinate space and along the X-axis
of the target coordinate space.

Local coordinate space and global coordinate
space
The coordinates of an individual DME channel are called
its local coordinate space. The coordinates common to all
channels are called the global coordinate space.
By switching from local to global coordinate space, you
can add new movement to the movement of images in
individual channels, and also apply transformation effects
to multiple channels that have been combined by Global
effects.

Three-dimensional parameters
Three-dimensional parameters are X, Y, and Z values
which define the position of an image, its axis of rotation,
the position of an imaginary point of view on the image,
and so on.
The standard values of parameters are as follows,
depending on the aspect ratio of your monitor (4:3 or
16:9).
Values for 4:3 mode
• Origin at center of image (source coordinate space) or
center of monitor (target coordinate space)
X = 0.00, Y = 0.00, Z = 0.00
• Upper right corner of image or monitor
When using SD format signals: X = 4.00, Y = 3.00,
Z = 0.00
When using HD format signals: X = 12.00, Y = 9.00,
Z = 0.00
• Lower left corner of image or monitor
When using SD format signals: X = –4.00, Y = –3.00,
Z = 0.00
When using HD format signals: X = –12.00, Y = –9.00,
Z = 0.00
