Set
keyframes for spline vertices and tangents over the course of the
clip.
To
animate a spline:
Move
to the frame where you want to begin animating the spline.
If
necessary, do one of the following to display the spline you want
to animate:
From
the Warp or Morph menu, click Source to display source splines,
or click Destination to display destination splines. You can also
use the Show buttons to display both source and destination splines.
If
you are working with two clips, with either Input, Matte, or Result
selected in the View box, toggle the Input box to Input1 or Input2, depending
on which spline you want to animate.
Select
the spline in the clip or its node in the Distort schematic.
Enable
Auto Key in the Animation menu.
Select
Move mode in the Edit box, then select and move one or more vertices
to a new location. You can also move vertex tangents.
Advance
the positioner to a different frame then move some more vertices.
Continue
to move vertices and tangents as you progress through the clip,
so the spline follows the movement of the feature you are warping
or morphing.
