Transcript

Captions can be provided in multiple languages
This can aid in learning a language, and can improve comprehension for ESL students
Captions vs subtitles? Captions usually convey sound effects, subtitles convey only spoken conversation
Various formats support more language fonts depending on encoding standards (various Unicode standards)

Media formats:
Flash (FLV) – Most portable and efficient, most options for accessibility. This is 80-90% of the media content on the web.
Quicktime – Some accessibility issues, issues with screen readers, can support captions
Windows Media – Middle of the road, supports captions and subtitles
Real Player – Supports caption text, subtitles, and overdub tracks, least popular media format

File Formats:
DFXP - W3C standard for Timed Text Authoring Format
SMIL – (Synchronized Multimedia Integration Language) W3c standard for XML markup for multimedia presentations
.SRT – Subtitle file format, YouTube’s officially supported format
SAMI – Microsoft format designed for caption playback on a PC

Players: (all Flash players)
Project readOn Player (you host the FLV, we do the rest)
YouTube (they host everything, you upload .SRT in multiple languages)
Google Video (good, but going away soon)
JW Player (great player, most options available)
NCAM Flash Player (another good option)
Adobe Plugin (requires development on your part)
Tools:
MAGpie (free software)
Subtitle Workshop (very flexible)
Overstream (online tool)
