Dotsub is a browser based tool that enables subtitling of videos on the web into and from any language. The mission is “to eliminate language as a barrier to cross-cultural communication using web video”.

The Dotsub tool can be used by professional translators, or it can be offered in an open, “wiki” type environment. Dotsub gives anyone the ability to translate video content from one language into multiple languages, producing subtitles rendered over the bottom of the video. The resulting repurposed video files can then be shared or downloaded and distributed across multiple devices.

Partnership Summary

This partnership brings together Brightcove, the leading online video platform, with Dotsub, the only “one-stop” subtitling solution offering the ability to repurpose web based video content into captions, suitable for the hearing impaired, as well as multiple language subtitles, both created quickly and inexpensively from a browser.

This work can be done by either professionals, provided by Dotsub, working in a closed environment, or by volunteers working in an open, collaborative wiki environment. All Brightcove users will now have the ability to have their video content captioned and subtitled from and into any language, opening up new markets and communication possibilities never before possible. In addition, all captions & subtitles will be able to be rendered as fully searchable transcripts in any completed language, as well as time ‘slots’ for targeted ad placement. These features can be customized based on the specific needs of Brightcove clients.
