VTechWorks, the institutional repository at Virginia Tech, now supports captions and subtitles in its video playback feature. Video titles can help support information access for speakers of alternate languages and for the deaf.
One short sample video (the April 16 2007 tribute) with captions enabled is now online. Captions will appear automatically in the video playback window in VTechWorks.
In order to enable captions, a WebVTT file must be submitted to the VTechWorks item containing the video. The file is a simple, text based format with a list of time codes and captions. If you are curious about the file format, download the WebVTT file for the sample here; the strange looking symbols in this example represent a musical note symbol in the captions.
