You can modify the duration of a transition, modify the transition effect, and even specify a sound to play during a transition. Also, you can specify the time to spend on a slide before advancing to the next.
Use Duration to set transition speed. A shorter duration means that a slide advances faster, and a larger number makes the slide advance more slowly.
- Select the slide that has the transition that you want to modify.
- On the Transitions tab, in the Timing group, in the Duration box, type the number of seconds that you want.
Many, but not all, of the transitions in PowerPoint can be customized.
- Select the slide that has the transition you want to modify.
- On the Transitions tab, in the Transition to This Slide group, click Effect Options and select the option that you want.
