Described Video

Described video includes a secondary audio track synchronized with a video or presentation that provides descriptions of what is happening on-screen. Often included are descriptions of surroundings, speakers’ appearance, body language, and any other non-audio information. The description is added during pauses in dialogue and included as an optional audio track. At this time, described video is rare and not legally required.

Key principles of described video Include:

• Describing what is on screen
• Prioritizing essential information
• Using the present tense
• Remaining consistent with names of speakers and places

Descriptions should not:

• Explain or elaborate
• Interpret
• Add opinion
• Censor
• Summarize

Integrated Description

Many web video players do not allow for additional audio tracks as descriptive audio is not yet required by law. However, the principles of describing visual elements can create a more inclusive environment while presenting. To incorporate those principles, consider the idea of integrated description. Integrated description means effectively describing visual elements while presenting.

The most effective way to describe things is to be specific:

• Refer to size, position, or unique characteristics
  • Say: “The bookshelf is about six feet high, and is 75% full of books.”
  • Say: “I’m going to click on the close button in the top right of the window.”
    • Many programs and websites will include Tooltips that reveal the name of a button. Hover your mouse over the button until a small popup text appears. That text will be the accessible label a screenreader will hear or a voice control user will say to use that button.
  • Reference slide number, figure label, etc.
  • Refer to “the image of a horse in the top left” or “question number three”.
• Spell complex words out letter by letter. This will aid all participants with understanding and comprehension.
• Identify yourself and other speakers
  • Use your own comfort level, but consider introducing yourself and describing yourself.

Try to be concise and direct while including all relevant information.
