Each transition comes with a default speed that you can adjust. Watch this video to find out more.
Set the speed of a transition
A shorter duration means a slide advances faster, and larger numbers make the effect go more slowly. Select the slide that has the transition that you want to change.
On the TRANSITIONS tab, in the Timing group, in the Duration box, type the number of seconds that you want it to run.
If you want all the slide show's transition effects to use the same speed, click Apply To All.
Each transition comes with a default speed that you can adjust.
For example, let's click More to open the Transitions gallery and click Page Curl to apply that transition.
The transition looks like a page being turned.
To see the speed setting for the transition, look in the Duration box.
The transition's duration is set at 1.25 seconds.
I'll click Apply To All to apply the transition to all the slides.
And then, I'll click Slide Show to see whether I like the transition's speed, slide to slide.
I think the page turn could be a little slower.
I'll press Esc to return to Normal view.
To make the transition take more time, in the Duration box, I'll click the up arrow to increase the duration to 1.5 seconds.
Then, I'll click Apply To All.
Let's click Slide Show to see if we like the change.
Resuming from where we were, I'll click through some slides.
I do like the transition as it has slowed down a little bit.
Back in Normal view, note that I can vary the speed as well as the transition type for the selected slides.
For example, let's make the Section Header slides different. I'll press Ctrl as I select the Section Headers, Slides 5 and 9.
For these slides, I am going to apply a different transition, Peel Off, and I'll slow it down.
For Duration, I'll click the up arrow and increase the number to 2 seconds.
I'll start from the Title Slide and click Slide Show to see how this looks.
Clicking from the Title Slide, we have the Page Curl transition on each slide, until we get to the first Section Header.
And there, the page peels off and the transition goes more slowly.
The slides in the section once again use the Page Curl transition, but change to the slower Peel Off transition at the next Section Header.
Now, you can make effective use of transitions, adding visual interest and variety to your slides.
