A video file is defined by two characteristics: its format and the codec within it. The file format is the container. It is characterized by a specific extension to the filename (AVI, MOV, WMV, MPG, RM, VOB, OGG, MP4, etc.). This defines how data is organized. For a video file, the data is described in flows (streaming video and audio streams).
