Every transition you add to a slide within PowerPoint 2010 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 durations 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. While transition duration is what we are exploring in this tutorial, transition time is the actual time that the slide stays during a slide show before moving to the next slide. Transition timings are purely optional, since you can choose to let any slide show as long as you want and only move to the next slide with a mouse click. Transition duration though is not optional — even if you do not change the duration, there still is a default duration for each transition effect.
