Assessing the accessibility of your video production requires you to consider how your video can be accessed and understood by people with different abilities. To do this, you can use captions and subtitles, which are text versions of the audio content that appear on the screen, helping people who are deaf or hard of hearing, or who speak a different language to follow your video. Audio description is another tool, which is a narration that describes the visual content of your video and can help people who are blind or have low vision, or who have cognitive or learning difficulties, to understand your video. Transcripts are text versions of the entire content of your video that can help people who have trouble accessing or viewing your video, or who prefer to read rather than watch your video. Finally, there are keyboard and mouse alternatives such as voice commands, touch screens, or switches which can help people who have physical or motor impairments, or who use assistive devices, to control your video.
