About
Live Studio uses role-based permissions to determine who can access Studio view and what they can do during a session.
Everyone opens the session using the same link. Live Studio recognizes each person’s role and automatically directs them to Studio view or Attendee view.
Available access and controls also depend on the session type:
- Virtual studio broadcast – Uses the full Kaltura Room experience for sessions with one or more speakers.
- External broadcast – Uses a simplified Studio experience for monitoring and managing a stream supplied by an external RTMP encoder.
Assign and manage roles
Roles are assigned and managed from the session’s edit page. You can access the session’s edit media page from My Media or directly from the session page.
Access the edit page from My Media
In My Media, locate the Live Studio entry, click the three dots to the right and select Edit from the menu options.

Access the edit page from the session page
- Open the Live Studio session.
- Click the three dots at the lower right of the screen and select Edit from the menu options.
Make sure you’re in Attendee view. If you’re in Studio view, use the blue button at the top of the page to switch views.


The edit media page displays with the Details tab selected by default.
Assign roles
- On the edit page, click the Roles & Permissions tab.
- Add collaborators, Room moderators, Chat moderators, and speakers as needed.

The Roles & Permissions page displays.

Room moderator and Chat moderator are separate roles. Assign both roles to users who need to manage the session as well as moderate chat and Q&A.
