Accessibility on social media

Accessibility on social media: Photos

  • Captions should act like alt texts
    Describe what is happening in the image

  • In cases where captions cannot be used as alt texts, include link that points to an image with an alt text or descriptive caption.
    Using an image on Twitter? Link to a site that contains the same image and an alt text

Accessibility on social media: Audio

  • Complete transcript must be attached to audio
    Can be done using YouTube closed caption function
  • Title of file must describe audio
    Example: uOttawa Orchestra playing Mozart’s  Symphony No. 6

Accessibility on social media: Video

  • YouTube is the best video-sharing network for accessibility
  • Complete script + complete described text = accessible video
    Must add script + described text as closed captions in order to automatically generate transcript
  • Avoid rapid scene changes
    Requires longer described text
  • Subtitles must sit ABOVE closed captions

Bilingual videos

  • Always create two versions of the same video

    –Single videos are harder to search for
    –Titles too short for two languages

  • Additional considerations required for bilingual videos–Complicates closed captioning
