Instruction manual for content producers on enhancing video accessibility (2025 edition)
In today's digital age, video content has become a dominant force, accounting for 82.5% of all internet traffic. With this surge in video consumption, it's crucial to ensure that this content is accessible to everyone, including those with disabilities. Here are some best practices for implementing video accessibility, focusing on adhering to standards like the Web Content Accessibility Guidelines (WCAG) and legal requirements such as the Americans with Disabilities Act (ADA) and Section 508 compliance.
The Importance of Video Accessibility
In 2025, over 430 million people experience disabling hearing loss, and over 2.2 billion people worldwide live with vision impairment. To cater to these audiences, content creators can incorporate several key components into their videos:
- Closed Captions: Provide accurate, synchronous captions for all spoken dialogue and important audio cues. Ensure captions meet a minimum contrast ratio (4.5:1), use readable sans-serif fonts at 14-18px size, limit line length (max 32 characters), and perfectly match speech timing.
- Transcripts: Offer full text transcripts including dialogue, speaker identification, and descriptions of relevant non-speech sounds. Structure transcripts for easy screen reader navigation and make them easily accessible alongside videos.
- Audio Descriptions: Include narrated descriptions of key visual elements for blind and low-vision users, explaining important objects, actions, or scene changes not obvious from audio alone.
- Keyboard Accessibility: Ensure video players are fully operable with keyboard controls to accommodate users who cannot use a mouse.
- Contrast and Readability: Maintain text contrast ratios (4.5:1 minimum), use legible fonts and sizes, and limit on-screen text length.
- Use of Auto-captioning Tools: Leverage automatic captioning tools but always review and manually correct captions for accuracy to avoid errors that hinder accessibility.
- Engagement of Viewers in Accessibility: Encourage or enable community contributions such as descriptive comments or visual descriptions to enrich video accessibility.
Legal Requirements for Video Accessibility
In the U.S., the ADA, Section 508 of the Rehabilitation Act, and the 21st Century Communications and Video Accessibility Act (CVAA) enforce video accessibility for public-facing digital content. In the EU, the European Accessibility Act (EAA) officially took effect on June 28, 2025, requiring all new digital content, including videos, to be accessible to people with disabilities.
Examples of Accessible Video Content
Several content creators prioritise accessibility in their video content. For instance, Vox consistently provides accurate closed captions, descriptions of visuals, and supporting transcripts or companion articles. TED-Ed's animated lessons include edited closed captions, descriptions of complex visuals, and full transcripts.
Tools for Video Accessibility
Free tools like the one from Paths to Literacy allow for adding audio descriptions to YouTube videos. Kapwing's Auto-Transcript feature generates a written transcript of a video's audio, and their closed caption generator helps create accurate, customizable closed captions for videos quickly and intuitively.
In conclusion, by integrating these practices—accurate captions, transcripts, audio descriptions, keyboard operability, and community engagement—content creators can produce videos that are more inclusive and compliant with ADA, Section 508, WCAG, and EAA guidelines. A more accessible internet is within our reach, and it's up to us to make it a reality.
In the realm of science, technology, and health-and-wellness, accessibility in video content is of paramount importance, given the growing number of people with disabling hearing loss (over 430 million) and vision impairment (over 2.2 billion) worldwide. Thus, it's crucial for content creators to comply with legal requirements such as the ADA, Section 508, WCAG, EAA, CVAA, and the EU's European Accessibility Act to cater to diverse audiences.
