Content in Motion | Curating Europe’s Audiovisual Heritage Conference, December 3-4 2015; www.euscreenxl2015.eu The presentation looks at the story of Amara – the world’s most popular crowdsourcing platform for subtitling video. The software was born out of a desire to see video become more accessible. This is made possible through the use of captions, for viewers with hearing loss, as well as subtitles, for anyone who doesn't speak the language a video was recorded in. Amara is developed and maintained by a mission-driven nonprofit organization, the Participatory Culture Foundation. The platform has grown from a simple DIY tool into a complex ecosystem. Amara currently integrates volunteer and community-based approaches to subtitling, as well as professional services (for sustainability purposes). Amara is used in many ways by individuals and organizations alike. Some people volunteer by captioning videos upon request, but there are also larger communities that gather around a specific organization or video publisher and translate videos – some into dozens of languages. Additionally, organizations including TED, the US National Archives, and Vimeo, have all used Amara to make video more broadly accessible.
