About video accessibility

Video accessibility is important in ensuring all members of the audience can access the content in an equitable way. This can involve the production of captions, a transcript, and audio descriptions, as well as the use of an accessible media player for playback.  

Accessible video tips: 

  • Use supported video file formats that support closed captions and subtitles,
  • Avoid compressing your media filesoptimising media compatibility or turning your presentation into a video – closed captions, subtitles or alternate audio tracks for video description are not preserved,
  • Include captions with readable text overlay and an interactive transcript,
  • Plan for audio description of visual information,
  • Plan for live captioning, audio description and sign language availability for any live online events you host,
  • Use an accessible media player,
  • Consider speaker visibility – some users use mouth movement to understand spoken language, so ensure the speaker’s face is visible,
  • Avoid using media content that flashes more than three times in any one-second period.

Kaltura Media Player

City uses the new, improved and more accessible version of Kaltura Media Player. The player has features that improve the accessibility of video media by staff and students by giving more control over the pace of content consumption and customisation. 

Interactive Transcript

The player provides an Interactive Transcript feature that can be displayed or hidden. You can play the video and follow the transcript. The text is highlighted as the video plays. 

You can search for a specific word or term and select to navigate straight to that location in the video. You can also download a text file of the transcript. 

Caption options

To improve the readability of captions on the videos, you can now increase the font and change the colour and background of the Kaltura captions. 

Control the playback

You can continue to change the playback speed of the video, and to move quickly or slow down at chosen parts of the content.
