Trimming a Video

You can trim out parts of any video using the Editor. The Trimming tool allows you to edit your videos by setting new start and end times for your media, or by splitting your media into several pieces so that sections can be removed from the beginning, middle, or end.

Note: Trimming changes the original file, and the change cannot be reversed.

Managing Chapters and Slides

Chapters are like bookmarks, which can be used to navigate through a video. You can use chapters to mark the beginning of a new topic, highlight important segments, or help navigate through a longer video. You can add, edit and delete chapters and slides in the Timeline tab under Edit in your My Media.

A Slide is a visual element synchronized to the main media. Slides can be viewed inside the player, simultaneously with the media.

After Chapters and Slides are created, the player will display the Navigation Panel: a list of chapters and slides available alongside the main video content.

Watch the video below for a demonstration of how to add chapters and slides.

    Adding Captions in MediaSpace

    Automatic Captioning

    As of October 2022, machine captions in English are automatically ordered for all media uploaded to Langara Mediaspace, and are available an average of 30 minutes after upload. Adding captions to videos makes them more accessible to various groups, including deaf/Deaf/hard-of-hearing people, people with sensory processing disorders, and people for whom English is a second language, among others. Machine captions are automatically generated by a computer, and are approximately 85-90% accurate. If you require your captions to be closer to 100% accurate, you may need to edit the captions to close that gap. See Editing Captions below for more information.

    If you are a student and require captions on your course materials, please contact Accessibility Services for assistance.

    Deactivating or Deleting Captions

    If you don’t want captions to appear on your video, you (and any Co-Editors you may have added to the entry) can deactivate them in the settings on your media entry before you share the media.

    1. Visit your My Media page and click on a media entry
    2. Click Actions > Edit
    3. Click the Captions tab
    4. To the right of the caption, choose the X to Delete the caption (Delete), or the far right icon to hide the caption from viewers (Don’t Show on Player)
      The Captions tab of a media entry in Edit mode. The pointer is hovering over the X icon.   The Captions tab of a media entry in Edit mode. The pointer is hovering over the "Don't Show On Player icon.

    Requesting Captions

    Captioning tools are available to all users on Langara’s Kaltura MediaSpace platform, both from the website at https://mediaspace.langara.ca, and from within Brightspace via My Tools > My Media. Machine captions are automatically generated when you upload new videos, but see the steps below to manually request additional captions for your media entries.

    1. Go to your My Media library and click on the entry (video or audio) you want to caption
    2. Below and to the right of your video, click Actions > Caption and Enrich
    3. Scroll down to the bottom of the Order Captions area and click the Submit button (do not change any of the dropdown menu options: Service, Source Media Language – currently, only English is available – or Feature)

    See the video below for a demonstration of the captioning tool.

    Turnaround averages about 30 minutes. Once your caption file has been created, it will be automatically attached to your video and available via the “CC” closed captioning button at the bottom of any media player. Captions using this service are hosted briefly on a U.S. Server during the captioning process, but are deleted once the captioning file has been completed.

    Editing Captions

    Captions created using the MediaSpace machine captioning service are about 85% accurate. You can edit your captions for accuracy using the built-in caption editor.

    1. Navigate to your media entry and click Actions > Edit
    2. Click on the Captions tab below the media entry
    3. Click the Edit Captions button to access the caption editor
    4. Edit your captions as desired; remember to save often (try to edit the label, E.g. include edited, so users can tell they are not purely machine-captioned)

    See the video below for a detailed demonstration of the Closed Caption Editor.

    Downloading Captions

    You can download caption files from any MediaSpace entry. This is recommended if you are keeping backups and you also want to preserve captions you’ve edited.

    Adding External Captions to a MediaSpace Entry

    If you’ve created your caption file manually, or are adding them from some other source (like a caption file created using a screen capturing program like Screencast-o-Matic) you can upload and attach the caption file to your MediaSpace item after upload. Just go to Actions > Edit, and choose Captions.
