Before we look at the different ways of using a video, let's just cover the basics. Once a video is inserted into Prezi, you can decide how and when it plays.
If you want the video to play automatically, then you'll need to add it to a path, just like we did with image files in Chapter 5, Best Practices with Imagery.
Once you are in the path editing mode, simply clicking on the video thumbnail on your Prezi canvas will add the video to your sequence of paths. This will mean that the video plays automatically, once this point is reached in your presentation.
