IVF — Simple Video Container for VP8/VP9

IVF (Intra-coded Video Frame) is a minimal video container format originally developed by On2 Technologies (later acquired by Google) to store VP8 and VP9 video codec test vectors. An IVF file contains a small binary header followed by raw encoded video frames, with no audio track and minimal metadata.

IVF and the WebM/VP9 Ecosystem

IVF files are commonly encountered when working with the VP8/VP9 codecs or the libvpx encoder library. Google's codec development tools, AOM (Alliance for Open Media) tools, and dav1d test suites produce IVF files as a convenient single-stream container for codec development and quality testing.

Converting IVF Files with LetsConvert

LetsConvert converts IVF files to WebM, MP4, MKV, and other formats using FFmpeg. Since IVF is audio-free, the output will also lack audio unless a separate audio track is provided. VP8 and VP9 streams in IVF are remuxed losslessly into WebM (the standard container for these codecs).

Why Convert from IVF?

IVF is a developer-oriented format not supported by media players or video editing applications. Converting to WebM or MKV makes the VP8/VP9 content accessible for playback and distribution.

Common IVF Conversion Targets

IVF → WebM: Convert to the standard web container for VP8/VP9 video.
IVF → MKV: Convert to the open Matroska container for broader compatibility.
IVF → MP4: Convert to the universal container (requires H.264/H.265 transcoding for VP8/VP9 content).

Frequently Asked Questions: IVF Format

Why does my IVF file have no audio?

IVF is a video-only container by design. It holds only one video stream with no audio support. To get a video with audio, you need to combine the IVF with a separate audio file in a container like WebM or MKV.

What codec is inside my IVF file?

IVF files typically contain VP8 or VP9 video. The codec is indicated in the 4-byte codec tag in the IVF file header (e.g., "VP80" for VP8, "VP90" for VP9).
