While the Distort module uses splines to define features of a clip you want to warp or morph, you can also use the Warper module. Instead of splines, the Warper uses meshes to define affected features for similar warping and morphing effects.
Mesh-based warps and morphs created with the Warper can be more time-consuming since meshes have many more points to work with and usually cover the entire clip. The Warper can be useful, however, because you have more direct control over the parts of the clip being altered since you manipulate the mesh directly.
For more information, see Warper.
