Video transcripts, captions and audio descriptions

If you publish video, it must be accessible to people who cannot hear audio or see video footage.

We can create the required accessible alternatives for your video.

What are transcripts, captions and audio descriptions?


Transcripts provide speech content and other important contextual information. They are created manually from the original video files provided. Transcripts do not just include the speech in the video, but also relevant visual information, such as text on the screen, diagrammatic information and important camera shots.


Transcripts are converted into caption files and associated with the video. Captions include all relevant audio information, such as speech, music and important sounds.

The use of synchronised captions enables people who are deaf or hard of hearing to watch video.

Audio descriptions

Audio descriptions are narration added to the soundtrack to describe important visual details that cannot be understood from the main soundtrack alone.

Audio descriptions enable people who are blind or vision impaired to hear a description of what is happening in the video, which is not direct speech.
