it depends on which method you use as both are different.
unfortunately the geniuses at adobe decided to take something that was called a "motion tween" for over 10 years and then rename it "classic tween" and create something totally new and name it "motion tween". I can't fathom the thought process over there sometimes.
now every book and tutorial out there that mentions "motion tweens" totally screws up anybody starting to learn with a different version.
they should have just called it an object tween and saved the world the trouble.
