In Panopto you can update share settings at the folder level or at the session level. If you change settings at the folder level, any new session added to that folder will have the same share settings by default. If you change share settings at the session level, it will only affect that session.
Navigate to luc.hosted.panopto.com and open your Panopto folder.
You can access a course folder in Panopto by logging in through Sakai and selecting the Panopto tool.
