Every transition you add to a slide within PowerPoint 2013 has a fixed, default duration. Some transitions such as Cut happen sooner than you can imagine (just 0.10 seconds). Some others like Reveal can take 3.40 seconds to be done with. But you really do not need to be happy with the default transition duration as you can make them to happen for as long, or as soon as you want. Before we show you how you can change the duration, do remember that transition duration and transition time are not the same.
