AVI is a Windows-native container, while OGV (Ogg Video) is the open-source video format from the Xiph.Org Foundation, combining Theora video with Vorbis audio in an OGG container. OGV was the primary open-source alternative to Flash video during the early HTML5 era (2009–2015), supported natively in Firefox, Chrome, and Opera without plugin dependencies. While WebM (VP8/VP9) has largely superseded OGV for web video, Theora-based OGV remains important in free software ecosystems, Wikipedia media files, and educational platforms committed to patent-free formats.
OGV is the only completely patent-free video format — Theora's VP3 codec was released into the public domain by On2 Technologies. If your project requires zero patent liability (government, educational, or free software contexts), OGV is the safest choice. Wikipedia uses OGV/WebM exclusively for hosted video files. Some educational platforms and government websites mandate patent-free formats for legal compliance.
FFmpeg decodes the AVI video and audio streams, re-encodes video to Theora using libtheora at the selected quality target (q1–q10, where q6 is roughly equivalent to H.264 at CRF 23–25) and audio to Vorbis using libvorbis. The output is wrapped in an OGG container (.ogv extension). Theora supports resolutions up to 1048560x1048560 theoretically, but practical use is limited to 720p due to encoding efficiency. Frame rate is preserved from the source.
Theora is a generation behind H.264 in compression efficiency — at the same bitrate, H.264 produces noticeably better quality. Theora at quality 6 is roughly comparable to H.264 at CRF 26–28. For acceptable quality at 720p, target 2–4 Mbps video bitrate. At 480p and below, Theora produces perfectly adequate results.

AVI to OGV conversion is the right choice when patent-free video is a requirement. While Theora cannot match H.264's efficiency, it provides legally unencumbered video suitable for Wikipedia, government, and free software contexts.
