Morphs are created by creating corresponding splines on two clips and linking them together. You then set interpolation values controlling how the features contained in the first set of splines morph into the features contained in the second set of splines. This method is called source interpolation. Finally, you blend the two clips over time to complete the morph. For example, you can draw splines around the outline of an actor and each of the actor's facial features. Then copy these splines onto a second clip containing the actor to whom the first actor will morph into. Edit the copied splines to more accurately contour the features of the second actor, link the corresponding splines, and then blend the two clips to complete the morph. Both sets of splines, those on the first clip, and those on the second clip, can be animated. Additionally, you can edit and animate the interpolated splines.

The general morphing workflow in the Distort module incudes the following steps.
| Step: | Refer to: |
|---|---|
| 1. Load clips into the Distort module. | Accessing the Distort Menu. |
| 2. Draw a source spline on the Input1 clip. |
Drawing Splines.
TipUse Distort's schematic as you work with
splines to help organize your work. See
Using Distort's Schematic.
