Tools for Captioning and Descriptive Video

Tools for Captioning and Descriptive Video

  1. MAGpie (Media Access Generator), at http://ncam.wgbh.org. Produced by the National Center for Accessible Media (NCAM) at WGBH (PBS) in Boston, MA. Tool for producing closed captions, descriptive video, etc., and outputting files in multiple formats including QuickTime, RealPlayer, SMIL, and SAMI. Version 2.0 is currently in beta testing.

  2. Apple QuickTime Pro (widely available), at http://www.apple.com/quicktime/products/. Supports multiple tracks for video, audio, closed captioning, description, etc. Limitation of current version is that captions, etc., are all part of one QuickTime file and therefore not read by screen readers such as JAWS and Window-Eyes. Reportedly this will be solved in the next version, which will also provide better support for SMIL (see Chapter 14).

  3. Synchronized Multimedia Integration Language (SMIL), at http://www.w3.org/AudioVideo/. A W3C specification for coordinating synchronized display of multiple media tracks such as video, audio, captions, descriptions, etc. SMIL is an XML application. RealPlayer 8 Basic can play SMIL documents, allowing users to toggle audio descriptions and captions on and off.
