How do I unpublish a file from Media Gallery?
You may unpublish a video, audio, or image file directly from your Canvas site's Media Gallery by using the Remove from Channel option. This includes files that are not owned by you, which have been published in the Media Gallery of a course you are teaching.
Go to Media Gallery.

Select Media Gallery from the Course Navigation Menu.
Note: To access the Media Gallery tool in a McIntire School of Commerce course site, select McIntire Kaltura from the Course Navigation Menu instead of Media Gallery.
Access the Media tab.

If you are viewing a file in Media Gallery and any playlists have been created in the course, the Playlists tab will display as the first page. If this is the case, select the Media tab to go to it.
Note: The Media tab will display with the number of files currently included in it, for example, 12 Media.
Select the Advanced Menu.

- Hover over the media thumbnail or use the Tab key on your keyboard to navigate to the file you would like to unpublish to bring up the gallery item details.
- Select the Advanced Menu (...) icon.
Select Remove from channel.

The Remove from channel icon looks like a red circle with an X.
Confirm removal.

A warning will display indicating that you are about to remove the file from the Media Gallery where it appears. Select Remove to confirm.
Note: After the media file has been removed, you may need to refresh your page to see the changes reflected in your Media Gallery.
