About MID to OGV Conversion
MID (Standard MIDI File) encodes musical performance as structured event data — notes, velocities, timing, instrument assignments, controller messages — in a compact binary format established in 1983. MIDI files typically occupy only 10-100 KB because they store instructions for synthesizers, not audio waveforms themselves.
OGV (Ogg Video) is Xiph.org's open-source multimedia container using Theora video and Vorbis audio codecs. Converting MID to OGV renders the MIDI through a software synthesizer and wraps the resulting audio in an OGV container. Since MIDI has no visual component, the output is an audio-only OGV file — an uncommon format primarily used for Wikimedia, open-source platforms, and web applications that mandate patent-free formats.
Why Convert MID to OGV?
Wikimedia Commons, Wikipedia, and certain open-source content platforms require OGV format for multimedia uploads. If you need to publish rendered MIDI music on these platforms, OGV is the required container. The patent-free Vorbis audio codec satisfies open content licensing requirements.
OGV is also used by web applications that specifically need patent-free multimedia containers for legal compliance. For organizations that cannot use patent-encumbered formats (H.264, AAC), OGV provides a fully open alternative for distributing rendered MIDI audio content.
Common Use Cases
- Uploading MIDI-rendered audio to Wikimedia Commons as OGV multimedia files
- Publishing synthesized MIDI music on platforms requiring patent-free multimedia formats
- Creating OGV audio assets for open-source web applications needing multimedia containers
- Preparing MIDI composition previews for Wikipedia articles about music and composers
- Generating patent-free multimedia files from MIDI for educational content platforms
How It Works
FFmpeg decodes the MIDI file and renders audio through its built-in synthesizer with a SoundFont bank. Since MIDI contains no video, the output OGV file contains only a Vorbis audio stream within the Ogg container. Optionally, a dummy Theora video stream (single static frame) can be added to make the file a proper video-type OGV. The Ogg container uses a page-based structure with stream serialization, granule position timestamps, and CRC checksums for transport integrity.
Quality & Performance
Audio quality within OGV depends on the Vorbis encoding settings — quality 6 (~192 kbps) provides excellent results for synthesized MIDI content. The Ogg container adds no degradation. As with all MIDI conversions, the SoundFont used during synthesis is the primary quality determinant. Vorbis handles synthesized audio efficiently because the clean waveforms compress well with psychoacoustic coding.

Tips for Best Results
- 1Use Vorbis quality 5-6 for the audio stream — higher settings waste space on synthesized MIDI content
- 2Add a static image as a Theora video stream if the target platform requires a video component in OGV files
- 3Prefer OGG (audio-only container) over OGV unless the platform specifically requires the video container type
- 4For Wikimedia Commons uploads, check current format requirements — WebM may now be accepted alongside OGV
- 5Tag the file with Vorbis comments (title, description, license) for proper attribution on open content platforms
MID to OGV serves the niche requirement of patent-free multimedia containers, primarily for Wikimedia and open-source platform compliance.
