MIDI (.midi) files form the backbone of music archives at organizations like the MIDI Association, academic music libraries, and open-source music repositories such as the Mutopia Project. These institutions maintain vast .midi collections representing musical works from classical repertoire to contemporary electronic compositions. The .midi extension is standard in these archival contexts where abbreviated file extensions are considered informal.
OGV (Ogg Video) uses Xiph.org's Theora video codec and Vorbis audio codec within the Ogg container — all completely patent-free and open-source. Converting MIDI to OGV creates multimedia files suitable for Wikimedia Commons, Wikipedia, and other open-content platforms that mandate patent-free media formats for legal compliance with free culture licensing.
Wikipedia articles about musical compositions, instruments, music theory concepts, and composers often need audio examples. Wikimedia Commons — Wikipedia's media repository — requires patent-free formats (OGV, OGG, or WebM) for all uploads. Converting authoritative MIDI renderings of public domain compositions to OGV enables these audio examples to be embedded in encyclopedia articles.
Open educational resource (OER) platforms governed by Creative Commons licensing may require patent-free media formats to satisfy the 'free as in freedom' requirement. MIDI-rendered musical examples converted to OGV meet this standard while providing actual audio playback rather than relying on the reader's (often nonexistent) MIDI capabilities.
FFmpeg synthesizes the .midi events through a SoundFont engine to produce stereo PCM audio. For audio-only OGV, the PCM is encoded using libvorbis and wrapped in an Ogg container with the .ogv extension. For proper OGV with a video component (required by some Wikimedia upload policies), a single-frame Theora video stream is added — typically a score excerpt, composer portrait (public domain), or musical diagram. The Ogg container serializes the Theora and Vorbis streams using page-level multiplexing with proper chaining semantics.
The Vorbis audio within OGV at quality 6 (~192 kbps) delivers excellent fidelity for synthesized MIDI content. The Theora video component (if included) is typically a static image and does not require high quality settings. For Wikipedia audio examples, clarity and accuracy of the MIDI rendering matter more than sonic beauty — use a General MIDI SoundFont that represents instruments in their standard timbral character rather than an artistic SoundFont that colors the sound.
