If your computer comes with a webcam (either built-in, or USB), it is possible to use Windows Movie Maker to create short instructional video clips and post them to Desire2Learn. If you are using a Windows XP or Vista machine, chances are you already have Movie Maker installed. This handout explains how to use it to create a short video and post it to Desire2Learn.

Keep in mind that video files tend to be rather large, so this handout is intended for instructors interested in recording short 4-5 minute mini-lectures.
