BBDO How Is this Done?

I am trying to recreate the motions of the bbdo site using the Laco Tweening Prototypes…Here is what i am doing…placing objects all in one clip at all different percent sizes and then using the SlideTo and ScaleTo commands to zoom in and over to each of them…However, when using the ScaleTo it zooms using the middle anchor point of the entire clip…Is this the right way of going about it or is there another way…
