Not able to get the animating right.

I have been trying to get mouth shape animation and lip sync to work for a long time now. I am still not able to get it to work.

  1. I mean not able to get the lip sync right.
  2. There is no smooth tweening between going from one mouth shape to another. It is just switching to the next drawing from one frame to another abruptly. Whereas the movement of other parts are smooth.
  3. Not able to get the face to move from one place to another. I can tilt it but can’t move it from one place to another.

Here is what I did:

NOTE:
Incase anyone is wondering, I used the method outlined here this is much simpler than the one given in the tutorials.
