How to add or remove videos from Kaltura Playlists

Go to the Course Gallery in a Canvas course. 

Click on the Edit button by clicking on the hamburger icon on the top right corner of the page as shown in the screenshot below. 

Click on the Playlists tab from the resulting page as shown in the screenshot below.

Locate the playlist you would like to edit i.e. add or delete media and then click on the edit pencil icon under the Actions column. 

The resulting page would look similar to the page through which the playlist was created. Add the media you wish to add to the playlist by clicking on the + button on the Add Items to your playlist column and notice the media added on the Playlist column.

Click the Save button when all the media are modified with the playlist.
