iDPM Operations
Note Target Rotate displays only Target Rotate transform parameter values, even
when Source space is selected. The soft knobs still adjust either the Target or
Source space rotation parameters, however.
Crop Controls
The Crop On button located in the Crop pane, right side of the menu, is used
to activate the crop feature for the delegated keyer (this button is inactive
for Global channels). The Crop Edge data pad delegates the soft knobs to
control each side’s cropping, while the Crop Softness data pad delegates
edge softness control.
Reverse Controls
The Reverse controls are located to the left of the Crop pane. The front and
back sides of the transformed picture can be reversed vertically and/or
horizontally with these controls.
Path Controls
The path control pane is located at the top-right of the menu. S Linear , Linear ,
and Curve interpolation touch buttons are available. When Curve is selected,
soft knob controls for Tension , Continuity , and Bias soft knob become available.
You can also turn off transform interpolation and hold each keyframe’s
values with the
Path Hold touch button.
Note Use the Path controls in the E-MEM & Timeline menu to affect all iDPM trans-
form and effect modifiers. Path controls in the iDPM menus are only used to
adjust path parameters of individual values of a transform or effect modifiers.
To specify a path for a transform, select the category of transform with the
data pads at the lower area of the screen. Then select the path type in the
upper-right pane, which will be labeled with that transform category.
When
Curve is selected, use the soft knobs or associated data pads to enter
values for tension, continuity, and bias.
All transforms except Spin apply the same path control to all that trans-
form’s parameters. Spin allows different paths to be specified for each axis
of the transform. When Spin is selected, the X , Y , Z , and All touch buttons are-
activated. The selected path will only be applied to the specified axis.
Clear Transforms
Two buttons located on the lower right side of the Enables pane ( page 74 )
are used to clear transform settings.
Clear X-Forms – Sets all transform parameters of the delegated keyer (or
global channel) to Default Keyframe values. The transform parameters
reside in the panels below the data pad delegation matrix and do not
