Overview

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.2

The story

Bink was inducted into the Front Line Awards Hall of Fame by the Game Developer magazine in 2009. The winners for the award were published in the January 2010 issue of the magazine.

Bink 2, a new version of the format, was released in 2013. This new format is available for Windows (standard, Microsoft Store and Windows 8 Phone), Mac OS, Linux, major touchscreen smartphone platforms (Android and iOS), all three major seventh-generation consoles (PlayStation 3, Wii, Xbox 360), all major eighth-generation platforms except the Nintendo 3DS (Nintendo Switch, PlayStation 4, PlayStation Vita, Wii U and Xbox One) and the ninth-generation PlayStation 5 and Xbox Series X/S. Bink 2 is faster than Bink 1, and supports higher resolutions as well.

Epic Games acquired the technology and business of RAD Game Tools including Bink on January 7, 2021, renaming it to Epic Games Tools. It was announced they planned to integrate RAD's technology directly into Unreal Engine and that licenses will continue to be available to those who do not use the Unreal Engine in their work.
