Convert XviD to OGV — Free Online Converter

XviD is the open-source MPEG-4 Part 2 codec that powered the scene release community's video distribution network throughout the 2000s. Created as a GPL-licensed alternative to DivX (its name spells DivX backwards), XviD was encoded into 700 MB AVI files optimized for CD-R burning and peer-to-peer sharing. The codec represented the community's commitment to free software — anyone could encode or decode XviD without license fees.

OGV (Ogg Video) is the open-source video container from the Xiph.org Foundation, using Theora video and Vorbis audio codecs — both completely patent-free. Converting XviD to OGV transitions content from one open-source video standard to another, maintaining the free software philosophy while gaining Xiph.org's container features and HTML5 web compatibility.

OGV provides native HTML5 video support in Firefox without any proprietary codec dependencies. For web projects committed to entirely open-source media stacks, OGV is the only video format that requires zero patent licenses from encoder to decoder to playback. Wikipedia and Wikimedia Commons use OGV as their standard video format for this exact reason.

While XviD and OGV share open-source principles, OGV has better web integration and metadata support than XviD's AVI container. The Ogg container supports Skeleton tracks for multiplexed stream indexing, Vorbis Comment metadata, and chapter markers that AVI cannot provide. However, Theora's compression efficiency is lower than modern codecs — this conversion prioritizes open-source purity over maximum compression.

FFmpeg decodes the XviD MPEG-4 Part 2 video and re-encodes it using the Theora video codec (libtheora), which is based on VP3 technology donated by On2 Technologies. Audio is transcoded from MP3 to Vorbis (libvorbis). Both streams are multiplexed into an Ogg container with proper page structure and granule position timestamps. Theora encoding uses quality-targeted mode for optimal visual results at a given quality level.
