Bink Video

Bink Video is a proprietary file format (extensions .bik and .bk2) for video developed by Epic Games Tools (formerly RAD Game Tools), a part of Epic Games. The format includes its own proprietary video and audio compression algorithms (video and audio codecs) supporting resolutions from 320×240 up to high definition video. It is bundled as part of the Epic Video Tools along with Epic Games Tools' previous video codec, Smacker video. It is a hybrid block-transform and wavelet codec using 16 different encoding techniques. The codec places emphasis on lower decoding requirements over other video codecs with specific optimizations for the different computer game consoles it supports. It has been primarily used for full-motion video sequences in video games, and has been used in games for Windows, Mac OS and all sixth-generation game consoles (Dreamcast, GameCube, PlayStation 2 and Xbox) and all major seventh-generation gaming platforms (Nintendo DS, PlayStation 3, PlayStation Portable, Wii and Xbox 360).[2] The format was reverse-engineered by the FFmpeg project and Bink decoding is supported by the open-source libavcodec library.
