As stated above, the Stories for Change site uses an application called ffmpeg (http://ffmpeg.mplayerhq.hu) to convert uploaded videos to Flash. This application supports most video file formats and codecs.

A video file format is a standard for encoding digital video, audio and some auxiliary information (metadata) into a file. In contrast to audio and image formats, most video file formats are containers, allowing for a variety of audio and video codecs to be used. See http://en.wikipedia.org/wiki/Video_file_format for more information.

A video codec is a software module that enables the use of compression for digital video, and an audio codec is used to convert audio to a particular file format. See http://en.wikipedia.org/wiki/Video_codec and http://en.wikipedia.org/wiki/Audio_codec for more information. A video file is created using specific video and audio codecs. What codecs are used depends on the tools that are used to create the video.
