Captioning videos

IMPORTANCE OF CAPTIONING VIDEOS

The Americans with Disabilities Act (ADA) is a federal antidiscrimination statute designed to ensure equal access to opportunities and benefits for qualified individuals with disabilities. In many state, government, and education institutions, videos must include ADA compliant captions. ADA compliant captions should:

• Be one to three lines of text that appear onscreen all at once, stay there for a few seconds and are then replaced by another caption.
• Be timed to synchronize with the audio.
• Not cover up graphics and other essential visual elements of the picture.
• Require the use of upper and lowercase letters.
• Use a font similar to Helvetica medium.
• Have a good resolution.
• Fit the 32-character-per-line requirement.

TIPS FOR WRITING CAPTIONS

• Captions should be synchronized and appear at approximately the same time as the audio.
• Words should be verbatim when time allows or as close as possible in other situations.
• Captions should be accessible and readily available to those who need or want them.
• Add music or other descriptions inside square brackets such as [music] or [laughter].
• Captions should appear onscreen long enough to be read.
• Speakers should be identified when more than one person is onscreen or when the speaker is not visible.
• Punctuation is used to clarify meaning.
• Spelling is correct.
• Write out sound effects when they add to understanding.
• All words are captioned regardless of language or dialect.
• Use of slang and accent is preserved and identified.
• Use italics when a new word is defined or a word is heavily emphasized when spoken.
