Kaltura Media Gallery

The Kaltura Media Gallery allows users to easily upload and share video, audio, and images within Sakai. Users can build dynamic collections of media that can be categorized, sorted and filtered based upon categories created. Files added to the Media Gallery can be reused and linked to other Sakai tools and across courses. Please note that the Kaltura Media Gallery is a ‘beta’ tool – and though it is stable and has been tested, it might also undergo more changes than other Sakai tools due to future improvements.

It is important to refer to copyright and fair-use guidelines before posting electronic course content.

Uploading Video and Other Media

Upon entering the Media Gallery, users will be presented with four tabs: Add Collection, My Media, Site Library and Permissions.

  • Site Library contains all uploaded media and is where one goes to upload new media.
  • My Media allows you to search any items you have uploaded into Sakai and add it to a library.
  • Collections are groups/exhibits of media put together from materials stored in the site library.
  • Permissions is where you can adjust who can see and add materials. Permissions may not be edited by users at this time.

The first step is to upload your media to the site library. The Media Gallery currently supports a wide variety of digital video, audio, image files, and codecs. Note: we do not recommend uploading files larger than 1000 MB, because the upload and conversion time can be prohibitive.

To begin uploading media, click on Site Library and then the Upload New Media button.

After clicking on Upload New Media, you will be taken to an interactive window with three tabs on the top, and three tabs on the side. The tabs on the top, “Video,” “Photo,” and “Audio” indicate which type of media you intend to put into your media gallery. On the left, you will find tabs for “Upload,” “My Content,” and other media sources such as “Webcam” or “Flickr” depending on your selected media type. Thus, by selecting “Upload” from the tabs on the left, and “Video” from the tabs on the top, the user indicates that he or she would like to upload video from a source file on his or her computer to the media gallery. Likewise, a user would select “Flickr” on the left and “Photo” on the top to transfer photos directly from his or her online Flickr collection. Note: “My Content” is a searchable field for posting content from one Sakai site to another.

Uploading materials to the Kaltura Media Gallery is a multi-step process. Do not navigate away from the upload window before a message is displayed indicating that all necessary steps are completed.

  1. For example, to upload a video file, click on the appropriate tabs (Video and Upload), and then Browse in the center of the window. Navigate to the location of the files you wish to upload and then click Open. The files are then added to your upload queue. Uploads will occur in the order in which they were added to the queue and will not commence until the Upload button in the lower left-hand button of the window is clicked. The length of time needed for this process to occur may vary widely depending on the size of the file, server activity, and upload speed. NOTE: We recommend uploading from a wired connection on the Duke campus when possible, since the Duke network provides a more robust infrastructure for handling large file sizes.
  2. Following the file transfer, click Next in the lower right corner. You will be prompted to enter a Title, Tags, Category, and a Description of the file if you wish.

While title, category, and description are somewhat obvious, tags may be thought of as keywords that other users would search for to find your media items, such as with an index of a book. Multiple tags can be added at once if separated by commas.

  1. Once you have added the appropriate information, click Next again in the lower right-hand corner. You should then see a message that the files are being converted and added.
  2. On the next screen, clicking Add More Media will restart the upload window. Finish takes the user back to the Site Library.
  3. Video and audio items may be accompanied by the following message, “Entry is Converting. Media is currently being converted, please try again in a few minutes.” Click “OK.” Please note that while the final conversion process is underway, video may play, but may not appear correctly. Please wait until this process has concluded before troubleshooting. Video can however be added to collections before final conversion is complete. You may need to refresh the tool or navigate away to see if the conversion process has been completed. IMPORTANT: You do not need to wait, or even stay in the Sakai course, while your video is converting. In other words, you can upload and process several video clips, then come back later once they’re done converting.

Once you have uploaded content to any Site Library, you can use the My Media tab to search your upload items and add them to the Site Library of the current Sakai course. Use the Search function to find items by tags or browser through media items. Once you find the item, click Add in the right-hand corner. The last step is to click the Add button in the pop-up window.

Viewing, Organizing and Updating Media in the Site Library

Once the media has been converted, the user is presented with a player window in the Site Library where a number of functions are available. Here instructors may:

  • Play the media file
  • Edit the details of the media file
  • Remove the media file from the site library

To play a video, click on either the semi-transparent “Play” button that appears in the center of the movie player window or on the smaller play button at the bottom left of the player. One can drag the playback time bar to either fast-forward or rewind the video.

At the bottom of the player, there are four options (Download, Embed, Edit Details, Remove). The Download and Embed Code buttons do not appear in the students’ player. This will deter students from reposting media outside of your course or capturing the file to view later or share. See the screen shot below.

Clicking on Edit Details leads to a window that is similar to what one sees in the video upload process, but with the additional option of editing permissions. These are:

  • Public: By setting an item to public, the user is allowing the item to be viewed by students in the site. When files are added to the library they are automatically private. If a user adds a private media item to a community collection or posts it to public tool in Sakai it will be visible.
  • Reusable: This indicates whether or not the video can be used within other Sakai tools such as Syllabus, Announcements, and Assignments.

Creating and Sharing Your Collections

Once you have uploaded the desired materials to the Site Library, you’re ready to begin making media collections. One might think of a media collection as a playlist based on a common theme. Items in the Site Library may be added to an unlimited number of collections. Collections may consist of just one media type (video), or may be a mix (video, audio, and images).

  1. Click on the Collections tab at the top of the window and then Add Collection. A box will appear prompting you for a collection Name, Description and Management Type. The Management Type determines what users may see the contents and which media, if any, they can add and remove from the collection. There are four settings for Management Type:
    • Instructor: Only site instructors may add items to, remove items from, or edit the settings of a collection. Any public items are visible to all users. This collection is preferred if the instructor does not need students to post media items.
    • Community: All site members may rearrange, add and remove items from the collection. This is useful for group and class projects.
    • Personal: Any site member may add items, but members may only manage the items they themselves added to the collection. If it is a private item, only the original owner and instructors can view the item. This setting allows students to share media items with their instructors.
    • Owner: Only the collection owner may make changes to items in the collection. It is not visible to others if the items are private. This is best for organizing private media items.
  2. Select the type of collection and click Save. You have now created your first collection.
  3. To add media to the collection, click on the Add Media link at the bottom of the window. This will take you to a new page where you can see the current contents of the collection on the left, and all the available items from the Site Library on the right.
  4. To add items to the collection click on specific items on the Site Library panel on the right. Once you are satisfied with the items that have been added to the collection, and the order in which the items are arranged, click I’m Done at the top of the collection.In this view, users with administrative permissions over the collection will see three options above the media player: “Manage Media,” “Edit Collection,” and “Delete Collection.”
    • Manage Media: Returns the user to the collection builder interface where he or she can add or remove items from the collection.
    • Edit Collection: Allows the user to change the name of the collection, edit the description, and choose new sharing permissions.
    • Delete Collection: Deletes the Collection (but not items from the Site Library)

    Note: If you edit the details of an item in the Site Library, those changes do not automatically change in a collection. For example, if you want to make a public item private, you will need to edit it in the site library and any collection.

Inserting Media Items to Other Sakai Tools

Users are able to embed media content in their site library to the following tools available within Sakai course sites:

  • Announcements
  • Assignments
  • Forum
  • Polls
  • Questions and Answers
  • Schedule
  • Syllabus
  • Tests & Quizzes

Each of these tools uses a similar editor, which allows for the insertion of media items from that particular site’s media gallery. Click on the Kaltura Media Gallery icon (pictured below) in the editor’s toolbar and browse your Site Library to choose the item. It should now be displayed in the editor box.
