Who Benefits from Accessible Videos?
- Blindness: People who are blind rely on audio descriptions and other forms of alternative text to understand the visual elements of a video.
- Colour-blindness: Individuals who are colour-blind may have difficulty distinguishing certain colours in a video, which can make it difficult for them to understand the content.
- Low Vision: People with low vision may have difficulty seeing small text or other details in a video, which can make it hard for them to follow along.
- Deafness: People who are deaf or hard of hearing rely on captions and other forms of alternative text to understand the audio content of a video.
- Motor Impairments: People with motor impairments may have difficulty using a mouse or keyboard to control a video, so it is important to provide alternative ways for them to engage with the content.
- Cognitive Impairments: People with cognitive impairments may have difficulty processing complex information or keeping up with the pace of a video, so it is important to provide support to help them understand the content.
Steps to Create Accessible Videos
- Video Captions: Captions are essential for viewers who are deaf or hard of hearing. Captions provide a written version of the audio content in the video. There are two types of captions:
- Open captions – captions that are permanently visible on the video. These captions cannot be turned off by the viewer. They are commonly used in videos that are primarily intended for social media platforms.
- Closed captions – captions that can be turned on and off by the viewer. These captions can be added to a video after it is produced by creating a separate caption file, which is then synced to the video. These captions can be used in videos that are intended for a broader audience and that will be played on different platforms, such as television and streaming services.

- Video Transcripts:
Transcripts provide a written version of the spoken content in the video. They are useful for viewers who are deaf or hard of hearing, as well as for those who prefer to read rather than listen. There are two types of transcripts:
- Static – a written document that corresponds to the video. These transcripts can be provided as a separate file or embedded in the video’s description.
- Interactive – a transcript that allows the viewer to click on specific parts of the text to jump to that point in the video. This type of transcript can be provided as a separate file or embedded in the video’s description.
- Audio Description: Audio description is an additional audio track that provides a verbal description of the visual content of the video for viewers who are visually impaired. This includes describing actions, costumes, scenery, and other visual elements that are not otherwise conveyed through the audio. This can be added as a separate audio track or embedded within the existing audio track.
- Choose Accessible Video Formats and Players: It is important to use formats and players that are compatible with assistive technologies, such as screen readers and closed captioning devices. This will ensure that your videos can be accessed by a wide range of viewers.
- Use Colors Thoughtfully and With Good Contrast: This will make the video more legible for those with visual impairments. It is important to choose colors that have a high contrast ratio, so that text and images are easy to see against the background.
- Use Text that is Easy to Read:Use a font that is clear and easy to read, and make sure that the text is large enough to be visible. This will ensure that viewers with visual impairments can read the text in the video.
- Avoid Fast-flashing Content: It is important to avoid content that flashes quickly, as this can cause seizures in some viewers. This includes flashing images, text, and backgrounds. If you must include flashing content in your video, it is important to keep the flashes below a certain threshold and to provide a warning to the viewer.
Best Practices for Creating Accessible Videos
Beyond technical compliance, accessible video content should also prioritize clarity, usability, and inclusive communication.
- Keep Captions Accurate and Synchronized Captions should match spoken audio accurately and appear at the correct time during playback.
- Identify Speakers Clearly When multiple speakers are present, identify who is speaking to improve comprehension.
- Use Plain and Understandable Language Avoid overly complex terminology or fast-paced narration whenever possible.
- Ensure Visual Information Is Explained Do not rely solely on visuals to communicate important information. Provide narration or descriptions when necessary.
- Avoid Auto-Playing Videos Unexpected audio can create usability challenges for screen reader users and individuals with cognitive disabilities.
- Design for Multiple Devices Ensure videos remain accessible across desktops, tablets, and mobile devices.
What are WCAG Guidelines for Video Accessibility?
The Web Content Accessibility Guidelines (WCAG) provide internationally recognized standards for accessible multimedia content.
Key WCAG recommendations for accessible videos include:
- Captions for prerecorded video content
- Audio descriptions for important visual information
- Accessible media controls
- Keyboard-accessible functionality
- Sufficient color contrast for on-screen text
- Avoiding flashing content that may trigger seizures
Organizations commonly follow WCAG 2.1 AA or WCAG 2.2 AA to support accessibility compliance across digital platforms.
