Described video is usually included in productions for the benefit of the visually impaired so that they can conjure an image of the production in their heads. In a described video, the narrator generally discusses the following elements:

• Physical characteristics—the physical attributes and facial expressions of each character.
• Scene description—the time of day, location, transitions, the passage of time, and scene changes.
• Visual effects—the setting, lighting, any dancing or choreography, and colors of each scene.
• Non-verbal communications—any communication that can not be heard (sign language, gestures, cues, etc.)
• Text on screen—all subtitles, titles, credits, and logos.

So as not to interfere with the audio of the production itself, the described video is usually integrated into the gaps between the dialogue of the production.
