Additionally, meeting organizers can easily share meetings with attendees and others, and track viewing of recordings using Panopto's sophisticated analytics tools. Panopto’s feature-rich environment allows users to view meeting participant video and shared content within the same window, and navigate throughout the presentation using clickable thumbnails, a searchable transcript, and optical character recognition performed on any text embedded in slides.
