Animating Splines

Set keyframes for spline vertices and tangents over the course of the clip.

To animate a spline:

1. Move to the frame where you want to begin animating the spline.
2. 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.
3. Select the spline in the clip or its node in the Distort schematic.
4. Enable Auto Key in the Animation menu.
5. 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.
6. Advance the positioner to a different frame then move some more vertices.
7. 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.
