When you watch The History of Labor Day video (embedded below) you'll see that it uses regular transitions every few seconds. You'll also notice that some short video clips have been interspersed throughout the video. Finally, the video includes background music to go along with the narration.
Frequent TransitionsStudents have a tendency to narrate over the same image for too long when creating audio slideshow videos. When the narration goes for too long the audience tunes out. To keep the audience's attention students should try to have a new image or at least a transition effect (zoom in, zoom out, pan) every few seconds.
Video Clips
Including a couple of short video clips within the audio slideshow is a good way to keep the overall video moving along. Obviously, it's also helpful in illustrating a point within the video project.
Background Music
Including some background music helps to keep the video feel like it's moving along. And it's helpful in covering up some of the "uhs" and "ums" that students sometimes make when narrating a video.
Adobe Spark Makes This Easy
Adobe Spark makes it easy to incorporate all three of the above aspects of an audio slideshow video project. Adobe Spark limits the amount of narration that students can record on each slide within their videos. Adobe Spark also includes a library of background muic that students can have inserted into their videos. Finally, students can upload short audio clips to include in their audio slideshow video projects. In this short video I demonstrate how to create a video with Adobe Spark.
