Convert MPEG to OGV — Free Online Converter

OGV (Ogg Video) is the video extension of the Ogg container, using Theora video and Vorbis audio — both developed by Xiph.org as completely open, royalty-free codecs. MPEG files use patented MPEG-1/2 codecs, while OGV provides a fully patent-free alternative. Converting MPEG to OGV produces video playable via HTML5 in Firefox and Chromium without any licensing concerns.

In the era of HTML5 video adoption (2010-2015), OGV was crucial for serving video without patent royalties. While VP9 and AV1 have largely succeeded Theora for new open-format video, OGV remains relevant for organizations with strict open-source policies, Wikipedia (which hosts all video as OGV/WebM), and legacy web applications built around the Theora codec.

For digital archives, museums, and government agencies that require patent-unencumbered formats for long-term preservation, OGV provides a completely free and open format with no future licensing risk. The Theora codec, based on VP3, is simple enough to guarantee decoder availability for decades.

FFmpeg transcodes using libtheora for video and libvorbis for audio: `-c:v libtheora -q:v 7 -c:a libvorbis -q:a 5`. Theora quality ranges from 0 (lowest) to 10 (highest), with 7 being a good general-purpose setting. Theora does not support B-frames and is purely I/P-frame based. The encoder is single-threaded, so conversion is slower than H.264.
