What is a .IVF file?
IVF is a simple container used for testing VP8, VP9 and AV1 video.
- Did you know
- IVF is a bare-bones wrapper developers use to test modern video codecs.
- The IVF name dates back to Intel’s old Indeo Video codec but the container was revived by On2 and Google as a bare test wrapper for VP8.
- An IVF starts with a 32-byte file header and gives each frame a small 12-byte header, deliberately omitting audio and rich metadata.

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