AnimationRate

AnimationRate
is an option for Animate and Animator that specifies at what rate an animation should run, in units per second.

AnimationRate->r specifies that the animation variables should be changed by r over the course of one second.

With AnimationRate->Automatic, the rate is determined if possible from settings for options such as DefaultDuration.
