About RMI to WMV Conversion
RMI (RIFF MIDI) and WMV (Windows Media Video) represent two generations of Microsoft multimedia technology. RMI belongs to the RIFF era of Windows 3.1 and Windows 95, when the Resource Interchange File Format unified WAV, AVI, and MIDI under a common binary structure. WMV belongs to the Windows Media era of Windows XP and beyond, using the ASF (Advanced Systems Format) container with VC-1 or WMV codecs. Converting between them spans Microsoft's entire multimedia evolution.
This conversion extracts MIDI from the RIFF container, synthesizes audio, and packages it in a WMV container. Since MIDI has no visual component, the output is an audio-only WMV file — used for Windows-specific media infrastructure that accepts only WMV input, such as digital signage controllers, legacy PowerPoint, and Windows Media Server.
Why Convert RMI to WMV?
Some Windows-based infrastructure only accepts WMV files — digital signage controllers from companies like Scala and Four Winds, legacy PowerPoint versions that import only WMV for multimedia, and Windows Media Server deployments. If rendered RMI audio must be delivered through these channels, WMV is the required container format.
WMV also provides a Microsoft-native upgrade path from the RIFF era to the Windows Media era. For organizations with extensive Windows multimedia infrastructure, converting RMI to WMV keeps content within the Microsoft ecosystem while moving it to a container format supported by modern Windows Media Foundation APIs.
Common Use Cases
- Providing rendered RMI audio as WMV files for Windows-based digital signage controllers
- Importing synthesized RMI music into legacy PowerPoint presentations that only accept WMV multimedia
- Creating audio-only WMV files from Windows kiosk RMI sounds for Windows Media Server streaming
- Preparing rendered DirectMusic RMI soundtracks for corporate Windows media libraries requiring WMV format
- Delivering synthesized RMI audio through enterprise content management systems that mandate WMV containers
How It Works
FFmpeg reads the RIFF container with RMID form type, extracts the MIDI data chunk, and synthesizes audio through a SoundFont engine. The rendered stereo PCM is encoded using wmav2 (Windows Media Audio v2) and packaged in an ASF/WMV container with header objects (file properties, stream properties, content description) and data packets. Since MIDI has no video data, the WMV contains only an audio stream. Some target systems may require a dummy video stream for file recognition — a single static frame can be added during conversion.
Quality & Performance
WMV is a container — audio quality depends on the WMA codec used inside. WMA at 192 kbps provides transparent quality for synthesized MIDI content from RMI files. The SoundFont determines the musical character; the WMV container and WMA codec preserve it adequately. For audio-only content, WMV is functionally equivalent to a standalone WMA file with additional container overhead.

Tips for Best Results
- 1Add a static background image as a video stream if the target Windows system requires a video component in the WMV file
- 2Use WMA audio at 192 kbps for transparent quality in the WMV container for synthesized RMI content
- 3Consider MP4 or standalone WMA instead of WMV unless the target system specifically mandates the WMV container format
- 4Test the audio-only WMV in your target Windows application before batch converting — some systems reject WMV files without a video stream
- 5Transfer metadata from the RMI's RIFF INFO chunks to WMV's ASF content description for proper display in Windows Media Player and file explorer
RMI to WMV converts legacy Windows RIFF MIDI into Microsoft's video container format. This is strictly for Windows-centric infrastructure that requires WMV input — for any other use case, convert to MP4, M4A, or FLAC instead.
