Robin Good: Amara / Universal Subtitles is a free web-based service that allows anyone to easily sub-title and add captions to any video. 


As long as you have a URL of a published video, Amara makes it very easy to caption it. The clip may be on a video sharing site or embedded in custom video player and Amara can still get to it.


Amara is made up of three main parts:


a) A subtitle creation and viewing tool (aka the widget)

b) A collaborative subtitling website


c) An open protocol for subtitle search/delivery


All tools inside Amara are free and open-source.


Supported video players and video sharing sites include:


Flowplayer JW Player Firefox native player Chrome native player
  YouTube Vimeo Dailymotion
