Bink Video

Bink Video is a proprietary file format (extensions .bik and .bk2) for video developed by RAD Game Tools.

The format includes its own proprietary video and audio compression algorithms (video and audio codecs) supporting resolutions from 320&times;240 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 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.

History
Bink has been primarily used for full-motion video sequences in video games, and has been used in games for Windows, Mac OS, Xbox 360, Xbox, GameCube, Wii, PlayStation 3, PlayStation 2, Dreamcast, Nintendo DS, and PSP.

The format was reverse-engineered by the FFmpeg project and Bink decoding is supported by the open-source libavcodec library.

Bink 2, a new version of the format, was released in 2013. This new format is available for Windows 8 (standard, Windows Store and Windows Phone), Mac OS, Linux, Sony PlayStation 4, PlayStation 3, and PS Vita, Xbox One, Xbox 360, Wii and Wii U, Nintendo Switch, Android and iOS. Bink 2 is faster than Bink 1, and supports higher resolutions as well.
