Common lecture recording techniques include voiceover and picture-in-picture. These approaches separate the lecturer from the content. The live composite video lecture technique avoids that by layering slide content directly over the video in real-time. This allows the lecturer to monitor slide content and interact with it as if it were projected about them in real space. The technique is easy to learn and can be accomplished with minimal hardware requirements and little-to-no post-production. Plus, research shows students prefer it over other video lecture formats.
