What is a .NUT file?
NUT is an open multimedia container from the FFmpeg and MPlayer projects.
- Did you know
- NUT was designed by the FFmpeg community as a clean, open media container.
- NUT was created by FFmpeg and MPlayer developers who found AVI, Ogg and Matroska too limited, aiming for a compact, patent-free and error-resistant container.
- Its design is deliberately Ogg-like but fixes shortcomings such as Matroska’s single-timebase limit, allowing streams with independent timebases.

- Depth of analysis
- .NUT 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 .NUT file
- Drag a .NUT 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.
