Shape tweening gives an effect as if one shape is appearing from the other over a period of time. This gives us the illusion similar to morphing. We can also produce a change in the size, skew, rotation, color and position of an object as we can do with the motion tweening.

                  Let us convert a simple square box of blue color into an oval of red color using shape tweening.

          2. Draw a square at Frame1 .
          3.Insert a keyframe at Frame25 as the ending frame for tweening.   
             4. With the frame25 selected delete the rectangle and draw an oval.

          6. Save and Test the Movie.
