MID (Standard MIDI File) stores musical performance as instruction data — note triggers, velocities, timing, instrument assignments — in a binary format created in 1983 by the MIDI Manufacturers Association. MIDI files are extremely compact (10-100 KB) because they contain instructions, not audio. A synthesizer must render these instructions to produce audible sound.
WMV (Windows Media Video) is Microsoft's video container using VC-1 or Windows Media Video codecs within an ASF wrapper. Converting MID to WMV renders the MIDI through a software synthesizer and packages the audio in a WMV container. Since MIDI has no visual component, the output is an audio-only WMV file — a niche format for Windows-specific media systems requiring WMV input.
Some Windows-based media servers, digital signage systems, and legacy corporate infrastructure only accept WMV files. If rendered MIDI audio must be delivered through these channels, WMV is the required container. Windows Media Player and Windows Media Center handle WMV natively.
WMV files can also be consumed by legacy PowerPoint presentations and Windows-based kiosk systems that import only WMV for multimedia content. Converting MIDI renders to WMV bridges musical composition with Microsoft-specific enterprise media infrastructure.
FFmpeg decodes the MIDI file using its built-in MIDI decoder and synthesizer, rendering all channels to stereo PCM audio. The audio is encoded using wmav2 (Windows Media Audio v2) and packaged in an ASF/WMV container. Since MIDI has no video data, the WMV contains only an audio stream with ASF header objects (file properties, stream properties) and data packets. Some target systems may require a dummy video stream for the file to be recognized as valid WMV.
WMV is a container — audio quality depends on the WMA codec used inside. WMA at 192 kbps provides transparent quality for synthesized MIDI content. The SoundFont used during MIDI rendering determines the musical quality; the WMV container and WMA encoding preserve it adequately. For audio-only content, WMV is functionally equivalent to a standalone WMA file with additional container overhead.
