What is a BK2 file?
A BK2 file is a video file saved in the Bink Video 2 format, which is the second version of the Bink proprietary video format developed by RAD Game Tools. It contains data compressed with the Bink 2 video and audio codecs. BK2 files are used for playing movie clips in video games on both PCs and console systems.
More Information
The Bink Video 2 format was released in 2013, replacing the original Bink (.BIK) format. The format provides considerably better performance than Bink while maintaining high video quality. BK2 files function as containers for data compressed with the Bink Video 2 and audio codecs. The compressed data may also be contained in .BIK2 files.
NOTE: Bink Video 2 is available for the Windows, macOS, and Linux, Android, and iOS platforms. It is also available for Xbox One, Xbox 360, Sony PS4, Sony PS3, Sony PSVita, Nintendo Switch, Nintendo Wii, and Nintendo WiiU.
