Time Warp curves enable you to control the velocity of an animation layer with a single spline curve. This lets you, for example, achieve Matrix-style bullet-time effects easily. The Time Warp curve can be found if you open the CATParent in the Curve Editor. You can also open it by clicking Layer Manager Curve Editor: Time Warps.
