Does anyone know how to distort a video to a set of tracked points?
For example, I have a stabilised (motion tracked) video of a face talking direct to camera and I wish to "pin" the points of the mouth and chin to prevent them significantly changing position.

The results might not look out of place in a SAW movie but there is a genuine need for the effect.
The reason is that the video will be applied as a texture to a 3D model which itself has the motion of the mouth and chin applied.
Restricting motion in the video will retain wrinkles and the subtlety of expression whilst allowing the 3D model to do the structural aspects.

Any thoughts?

The Warp Stabilizer VFX effect can do this, the way that the coconut is locked into position in this video:

Hi Todd,
Thank you.
I can stabilise the footage without any problem as I previously said.
The question relates to distorting the content to match specific track points.

Imagine a perfectly stabilised face (using Warp Stabilizer for example) which is fixed on the eyes and nose. Now, I wish to "pin" the moving mouth to set points to prevent the jaw movement from being visible during talking.

Is there a method that will do this that you know of?
