Always include captions and audio descriptions in your QuickTime multimedia.
For an example of a properly captioned and audio-described movie, download this zipped QuickTime clip called, 'Catch!' (The file is a little over 2.4MB in size). After unzipping, use QuickTime 4.0 to play it back on either a Mac or PC.
Don't have QuickTime 4.0? Check the multimedia software page before going any further. By the way, here is the captioned and described transcript for the movie, "Catch!".
To play the movie, open MoviePlayer and then open WAICatch.mov. The movie has been uploaded with both captions and descriptions turned on. You can toggle the caption and/or description tracks on and off as necessary by following the simple directions below:
MoviePlayer also lets you search the text track for specific words or phrases. To do so, open the Edit menu, choose Find and type in a word that appears in the captions. Press the Enter or Return key, and MoviePlayer will move to the first frame of the clip where the text appears. Note that this feature will work even if the text track has been turned off.
