If you are warping or morphing a live-action or moving clip, you must define the source mesh at several frames in the clip. The Warper interpolates the location and shape of the mesh between frames.
Creating a mesh over the length of a live-action or moving clip can be time-consuming. To simplify the mesh-building process, create the mesh for the first frame of the required clip, then use the Stabilizer to generate the successive meshes.
With the Stabilizer, you can track the movement in the clip, and then apply the tracking data to the mesh (tracking by Axis). This translates the mesh so that it follows the movement in the clip without changing shape. Alternatively, you can track the movement of selected points in the image, and apply the tracking data to the mesh (tracking by Vertices). This translates and changes the shape of the mesh so that it matches the position and shape of the image over the length of the clip.
