Make Video Accessible

Video Captioning

Captioned video provides many pedagogical benefits. Not only does it allow students with hearing disabilities to access the information in the video, it also allows all students to engage with information in a way that may be more effective for their learning styles. Research from Oregon State University, showing that 98.6% of all surveyed students found captions helpful, with 75% using them as a learning tool.

See the LSCS Web Accessibility Statement for information about LSCS policy and links to applicable law regarding captioning.

Captioning your own videos

LSC's lecture capture solution, TechSmith Knowmia, provides a path to publishing captioned video. 

TechSmith Knowmia videos provide the ability to caption videos in a straightforward fashion. See below:

NOTE: LSC-Online does not have caption editors or caption administrators available.

Linking to a video on another website

We recommend that any video you link to be captioned. To start with, the LSC Library has a wide selection of captioned media; check with your Subject Area Librarian. Other places you may find video to link to:


Almost all YouTube videos have a CC button, but be warned: they could be auto-generated captions that are sometimes quite awful.  To search for videos captioned by a human and not auto-generated, follow this easy search technique.

  1. Enter your search term (for this example, let's say I'm searching for videos on volcanoes) in the YouTube search field.
  2. Add a: , CC (that's a comma, CC)
  3. Hit Enter or click the magnifying glass icon.Shows YouTube search box with volcanoes,cc as an example.

To determine if a YouTube video has auto-generated captions or captions done by a human (much preferred):

  1. Click on the Settings button in the bottom right corner of the video player.
    Identifies the Settings icon.
  2. Choose Subtitles/CC.
  3. Make sure there is an English option, and not just an English (auto-generated) option.
     Shows English selection.


  1. Fill out the Advanced Video Search fields that you need.
  2. Choose the "Subtitles: Closed captioned only" option.
  3. Press Enter or click the Advanced Video Search button.

Recording Tip

Whenever you record audio or video, we recommend thinking of it as a radio broadcast where only your words and inflection come through. Materials that are solely visual, should be described verbally to be accessible to someone who is blind. If PowerPoint or other files are shown in a video, make the actual .ppt or .pptx files (source files) available to students for review.

Ensure media player is keyboard accessible

We know that YouTube, Vimeo, and the Distance Education streaming media players are keyboard accessible players. The other advantage to these players is that they optimize the video streaming to the user's best settings. If you are using a different video player, please test it to make sure it can be used by those who cannot use a mouse.

Keyboard accessibility

  1. Whatever the operation or behavior, make sure a mouse is not required.
  2. Use the following keyboard keys to navigate and interact with the web page and all of its content:
    • Tab
    • Arrow keys
    • Enter
    • Spacebar

PowerPoints with audio narration

It is best if you use Camtasia to record audio narration of a PowerPoint for several reasons (ease of captioning, ability to play on multiple platforms, ability to play without proprietary software), but if you are determined to create a PowerPoint with audio narration, visit this Microsoft support page. Make sure you confirm that all of your students have the software required to play the PowerPoint with the narration and subtitles.

Audio Descriptions

Need to describe the visual information on the screen for students who are blind?

Linking to an audio recording on another website

Please check to see if a transcript exists and make sure your students know how to find it (if it's available).
