What is a .BK2 file?
.BK2 is a file in the Game engines category. Analyser identifies it and reads the metadata in its header, right in your browser.
- Did you know
- BK2 is a Bink Video 2 file from RAD Game Tools, the codec behind cut-scenes and logo intros in thousands of console and PC games.
- Bink is licensed so widely that its startup logo has appeared at the front of countless games across every major platform.
- It is built for game hardware, decoding video efficiently while the game keeps running, which is why studios chose it over standard formats.
- What Analyser reads
- Identify game-engine assets: Unity (UNITYPACKAGE, .resS resource streams), Unreal Engine (UASSET, UMAP, .uproject / .uplugin descriptors, .ubulk bulk data, .ufont fonts, .locmeta / .locres localisation, .ushaderbytecode shaders), Godot (TSCN, TRES), Minecraft asset metadata (.mcmeta) and language files (.lang / .lng), and Bink Video 2 (.bk2) cutscenes.
- Depth of analysis
- .BK2 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .BK2 file
- Drag a .BK2 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
