The video below will show you how to upload video and audio from other sources to your Panopto course or My Folder. Panopto will accept many types of audio and video files. The video will automatically encode to allow it to play on any device including mobile, tablets and mobile phones. Once the video has finished encoding, you can edit it in the Panopto editor and add PowerPoint slides, quizzes and other media.
The Batch Upload User Guide can be found on the Panopto Support page.
