8.3. Ensure that videos have a transcription, closed captions (and audio description if applicable)
A user who is hard of hearing will benefit from having closed captions to relay anything spoken or heard into viewable text, while one with a severe visual impairment would benefit from a separate audio track describing the visual content of the video.
In order for a published video to be accessible, the following elements must accompany the video, in order of priority:
- A complete transcription.
- Captions.
- An audio description.
The publishing software and video player used supports these three features.
To be customized
If necessary, update the previous section to specify the features supported by the publishing tool and the video player used.
Transcripts
The transcription must provide in text form all the information provided by the video (speech, messages displayed on the screen, etc.). If necessary, images may be included in the transcription.
Captions
The captions must show in text format all the audio content included in the video.
They must not be displayed directly in the video, but must be attached to it in a separate text file (often an .xml or .srt file).
Audio descriptions
The audio description is added to the soundtrack.
It must provide in audio format all the information that is only accessible by images.
In the same way, this audio track must not be included directly in the video, but attached in a separate audio file (usually an .mp3 file).
Warning
If videos have been supplied for publication without these three features, they should be returned to the contributor and these features should be added.
To be customized
In the section above, enter the functionalities or fields used in the publishing software to add a transcription, a captions file and an audio description file.
