About the Interpolation Dialog Box
Click Animation > Animation Interpolation to open the Interpolation dialog box. The View Interpolation options define the manner in which the views defined in the View at Time dialog box change during an animation:
Select the Interpolate check box for a smooth transition from one view to the next,
Clear the Interpolate check box to jump to the next view without any transition.
Select or clear the Linear or Smooth check boxes under Translation and Rotation to finely tune the interpolation direction and method.
 
* If you want the animation to remain on a view for a specific length of time and then start moving toward another view, you must apply two instances of the same view (one at the beginning and one at the end of the time period), to keep the view constant. You can then apply a third view for transition.
The Transparency Interpolation options define the manner in which the transparencies defined in the Transparency at Time dialog box change during an animation:
Select the Interpolate check box to set a fade from one transparency event to another. You can change which transparency events are interpolated by dragging them in and out of timeline rows. When you drag an event out of an existing row, interpolation is cancelled, and vice versa.
Clear the Interpolate check box to treat the transition as a single change from one transparency state to the next.
