how to extract the audio from your videos. A related question that I got from a reader was about how to add background music to Screencastify videos. There are a few ways that you can add audio to videos that you make with Screencastify including uploading your video to WeVideo or iMovie then adding a background track. Those methods are fine, but there is an easier way.
To add background music to a video that you created with Screencastify all that you need to do is upload the video to YouTube then use YouTube's built-in editor and library of free music. In the following short video I demonstrate how to add background music to your Screencastify videos.

Adding some background music to a video can help reduce some of the echo or tinny sounds that sometimes occur in screencasts that are recorded without an external microphone. Adding background music can also have the effect of covering up some of the "ums" and "uhs" that we sometimes make when recording a video. Both of those audio improvements can lead to students viewing instructional videos for a bit longer or at least make paying attention a little bit easier.
