The online film portal ViKi is using the great idea of wikis, well known by the most popular Wikipedia, for films and exactly to provide films with translations and subtitles with the wiki feature being used to enable the translations. At all the site is a film portal with international films, which are translated by a community into various languages.
ViKi itself is a company, organizes the website and manages legal issues like licencing the films. The films are available to anyone and anyone may participate in the community to translate films. This is making the platform interesting to both film enthusiasts, who like to watch original films, and people having fun with languages in the need of good stuff. Currently the site shows mostly rather exotic films and tv series from far east or south america. To get some further information visit the about page of ViKi.
