About RMI to OGV Conversion
RMI (RIFF MIDI) is Microsoft's RIFF-containerized variant of the Standard MIDI File, designed for seamless integration with the Windows Multimedia Extensions architecture. The RIFF wrapper allowed Windows applications to handle MIDI through the same binary parsing infrastructure used for WAV and AVI, while the DISP sub-chunk provided file display names visible in Windows Explorer and the Open File dialog.
OGV (Ogg Video) is Xiph.org's open-source multimedia container using Theora video and Vorbis audio codecs. Converting RMI to OGV extracts MIDI from the Windows RIFF container, synthesizes audio, and wraps it in the patent-free Ogg multimedia container. Since MIDI has no visual component, the output is an audio-only OGV file — used primarily for Wikimedia Commons, Wikipedia, and platforms requiring patent-free multimedia formats.
Why Convert RMI to OGV?
Wikimedia Commons, Wikipedia, and certain open-content platforms require OGV format for multimedia uploads. If you need to publish rendered Windows MIDI content on these platforms — for example, synthesized renditions of historical or public-domain compositions stored as RMI — OGV is the mandated container. The patent-free Vorbis codec satisfies open content licensing requirements.
OGV is also used by web applications and organizations that cannot use patent-encumbered formats for legal compliance. For institutions migrating Windows multimedia archives to open-content platforms, RMI-to-OGV conversion provides the necessary format transformation.
Common Use Cases
- Uploading rendered Windows RMI compositions to Wikimedia Commons as OGV multimedia files
- Publishing synthesized Windows-era MIDI music on platforms requiring patent-free multimedia formats
- Creating OGV audio assets from Windows multimedia RMI files for open educational resource platforms
- Preparing rendered RMI compositions for Wikipedia articles about historical music and computing
- Generating patent-free multimedia from Windows kiosk RMI content for institutional open-access repositories
How It Works
FFmpeg reads the RIFF container, extracts the MIDI data chunk from the RMID form, and synthesizes audio through a SoundFont engine. Since MIDI contains no video, the output OGV contains only a Vorbis audio stream within the Ogg container. Optionally, a single-frame Theora video stream (static image) can be added to satisfy platforms requiring a video component. The Ogg container uses a page-based structure with stream serialization and CRC checksums for transport integrity.
Quality & Performance
Audio quality depends on the Vorbis encoding settings — quality 6 (~192 kbps) provides excellent results for synthesized MIDI content. The Ogg container adds no degradation. Vorbis handles synthesized audio efficiently because the clean waveforms compress well with psychoacoustic coding. The SoundFont used for synthesis is the primary quality determinant, not the container or codec.

Tips for Best Results
- 1Use Vorbis quality 5-6 for the audio stream — higher settings provide diminishing returns on synthesized MIDI content
- 2Add a static image as a Theora video stream if the target platform (like Wikimedia Commons) requires a video component in OGV files
- 3Prefer plain OGG (audio-only container) over OGV unless the platform specifically mandates the video container type
- 4Include Vorbis comment metadata (TITLE, DESCRIPTION, LICENSE) for proper attribution and licensing on open content platforms
- 5Check current Wikimedia Commons format requirements — WebM may now be accepted alongside OGV for new uploads
RMI to OGV serves the niche requirement of patent-free multimedia containers for Wikimedia and open-content platform compliance. Use it when open-access publishing of Windows MIDI content is required.
