Bink Video is a proprietaryfile format (extensions.bik and.bk2) forvideo developed by Epic Games Tools (formerly RAD Game Tools), a part ofEpic Games.
The format includes its own proprietary video and audio compression algorithms (video andaudiocodecs) supporting resolutions from 320×240 up tohigh 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 hybridblock-transform andwaveletcodec 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 forfull-motion video sequences invideo games, and has been used in games forWindows,Mac OS and allsixth-generation game consoles (Dreamcast,GameCube,PlayStation 2 andXbox) and all majorseventh-generation gaming platforms (Nintendo DS,PlayStation 3,PlayStation Portable,Wii andXbox 360).[2]
The format was reverse-engineered by theFFmpeg project and Bink decoding is supported by the open-sourcelibavcodec library.[3]

Bink uses a wavelet-based compression algorithm optimized for game video sequences. It supports resolutions up to 4K and can encode at bitrates from 500 kbps to 200 Mbps. The codec is designed for efficient decompression, leveraging multithreading and SIMD instructions on modern CPUs. Bink also offers optional alpha channel support for composing video with 3D graphics.[10]
