  • At Cal Poly we recognize the potential benefits of lecture capture technology for our students. To deliver these benefits, it is critical that the solution be simple, fast, scalable and accessible to all of our students. Panopto and Automatic Sync are addressing these challenges. By leveraging caption data to provide lecture navigation and search features, the CourseCast platform allows us to create content that is both accessible and helpful to our users.
