Professional-level lecture clips require not only a veritable studio’s worth of equipment, but significant resources to transfer, edit, and upload footage of each lesson. That’s why research scientists at Udacity, an online learning platform with over 100,000 courses, are investigating a machine learning framework that automatically generates lecture videos from audio narration alone. They claim in a preprint paper (“LumièreNet: Lecture Video Synthesis from Audio“) on that their AI system — LumièreNet — can synthesize footage of any length by directly mapping between audio and corresponding visuals.
