Web Accessibility Tools - Video Accessibility

Accessible videos will have captioning to ensure that everyone can access the information, whether they are deaf or do not have equipment on their computer for audio. Use the following tools to create captioning on your videos. 


Captioning Styles

Public TV station WGBH-TV pioneered closed captioning for television in the early 1970s. Drawing on this experience, the WGBH Media Access Group has put together a set of guidelines and suggestions for how captions should be styled and displayed. 



MAGpie is a free software tool developed by the Carl and Ruth Shapiro Family National Center for Accessible Media. It has become the industry standard for creating captions on Flash, Quicktime, Real, and Windows Media video. 



The Synchronized Multimedia Integration Language (SMIL, pronounced "smile") enables simple authoring of interactive audiovisual presentations. It is a protocol developed by the W3C that is used for "rich media" multimedia presentations, which integrate streaming audio and video with images, text, or any other media type. SMIL is an easy-to-learn, HTML-like language, which may be written using a simple text-editor.



Microsoft Synchronized Accessible Media Interchange (SAMI) was designed and developed to caption the digital media widely available in PC systems. The SAMI specification is supported by Microsoft Encarta Encyclopedia, Windows Media Player, and some Microsoft multimedia titles.
