After you add animation to a selected slide object, you typically set the animation event. Another animation property you can set thereafter is the speed of the animation. Every animation you add within PowerPoint 2010 has a fixed, default speed (duration). This speed or duration is typically shown in seconds or part thereof, and differs from animation to animation. For example, the default duration of a Fade animation is half a second (00.50) whereas for the Wheel animation, it is two seconds (02.00). Clearly this is a different approach than the behavior in previous versions of PowerPoint where you were limited to five speed presets.
