Bink is a proprietary video file format (extension .bik) developed by RAD Game Tools, and primarily used for full-motion video sequences in video games. It has been used in many games for Windows, Mac OS, Xbox 360, Xbox, GameCube, Wii, PlayStation 3, PlayStation 2, Nintendo DS, and Sony PSP. The format includes its own video and audio codecs, supporting resolutions from 320×240 all the way up to high definition video. It is bundled as part of the RAD Video Tools along with RAD Game Tools' previous video codec, Smacker video. It is a hybrid block-transform and wavelet codec capable of using 16 different encoding techniques allowing it to compress any type of video. The codec places emphasis on lower decoding requirements over other video codecs with specific optimizations for the different computer game consoles it supports.
The format was reverse-engineered by the FFmpeg project and Bink decoding is supported by the open-source libavcodec library.
