Section 4 — Menus Overview
The transform controls are organized on the menu according to Source and
Target space capabilities. See 3-D Digital Effects Concepts
on page 80 for
background information about 3-D image controls, including Source and
Target space. Note that some parameters intrinsically apply to either
Source or Target space, and have no meaning in the other space. Size and
aspect for example apply only to the Source space. Perspective applies to
the projection of the transformed image on the TV screen and has no
meaning in Source space.
The Locate , Loc Axis , Target Rot , and Spin transforms can be assigned to work
in either source or target space with the touch buttons at the left of their
pane. Selecting the
Source button provides image adjustment using that
channel’s coordinate system for reference. Selecting the Target button pro-
vides image adjustment using the screen as the reference. Only one space
button is selectable at a time.
Note Target Rot 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.
The Skew and Aspect transforms work in Source space.
The Persp. , Post Xform , and Final Locate buttons work in Target space.
Crop Controls
The Crop button in the pane to the right of the Transform buttons 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 Soft data pad delegates edge
softness control.
Reverse Controls
The Reverse controls are located to the right of the Crop pane. The front
and back sides of the Transform Engine picture can be reversed vertically
and/or horizontally with these controls.
Path Controls
The path control pane is located to the right of the data pad delegation
matrix.
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. See Path
Control on page 88 for an explanation of path controls.
