Deleting a large collection of videos individually can be time consuming. Instead, use the Bulk Delete option in the Media Library to select and delete multiple entries at once.
To delete a batch of content, click the checkbox to the left of each video to be deleted, then click the Bulk Delete button.
This will open the Bulk Delete window.
Click the x icon to remove a video from the Bulk Delete list (that video will remain in the media library).
Push the Bulk Delete button to delete all content on the list and return to the Media Library.
Note: There is no "Are you sure?" prompt while using this tool. Clicking the X icon or Delete button will immediately trigger the delete function
