Edit Video Content with the Media Editor

Instructors can edit video timelines, create chapters, and add closed captions. We recommend using the desktop experience when editing video files.


  • Edit timelines will allow users to skip unwanted sections of a video recording.
  • Create a Table of Contents for videos by creating chapter titles to allow quick navigation to specific sections.
  • Captions can be uploaded from a .vtt or .srt file or automatically generated to make videos accessible to all users.  

Note: In Content, the editor features are only available for newly uploaded audio-video files and do not apply to files that were uploaded prior to January 2022.

  1. On the nav bar, click Content.

    Closed Captions

    Adding Closed Captions is important, not only for accessibility, but also to allow viewers to search by keywords. Users have the ability to search for a keyword in the video caption track and see those spots reflected on the timeline. A caption track must be present for the video and the user must have captions turned on to use the search option.

    Create Closed Captions

    1. Select the language from the dropdown menu on the top left side of the video. This selection will be used for closed captions.
      Select Language for Closed Captions

You will be able to continue editing this media file after auto-generation is complete. If you proceed, all references to this media file throughout the LMS will receive your changes.”  Click Auto-Generate.

    Optimize for Streaming

    Depending on the file format of audio and video files, they might not play in a web browser by default. All MP3 and MP4 video files are saved in their original form because they can play in a browser without transcoding. Other files, such as WMV and AVI, which would not play by default, continue to be automatically transcoded.

    Note: This feature applies to uploaded audio and video files in Content and uploaded Video Notes. Original versions of videos are used for editing and playback. This feature does not apply to Video Note web cam recordings, which continue to be transcoded automatically.

    Click the Optimize for Streaming button to manually transcode original versions of the files. This will reduce the file size or enable multi-bitrate streaming.
