About RMI to MOV Conversion
RMI (RIFF MIDI) is Microsoft's RIFF-containerized MIDI format, deeply tied to the Windows multimedia stack — from the 16-bit mmsystem.h APIs in Windows 3.1 to the 32-bit DirectMusic framework in DirectX. The RIFF structure provided Windows applications with a unified binary format for all multimedia types: WAV for audio, AVI for video, and RMI for MIDI sequences. This integration meant any Windows application using the MCI command interface could play RMI files with a single 'play' command.
MOV is Apple's QuickTime multimedia container, the native format for macOS and iOS video production. Converting RMI to MOV extracts MIDI from the Windows RIFF container and renders it as audio within Apple's QuickTime framework. The output is an audio-only MOV file compatible with Final Cut Pro, iMovie, Motion, and the Apple professional video editing ecosystem.
Why Convert RMI to MOV?
The Windows and Apple multimedia ecosystems are fundamentally incompatible at the container level — Apple's Core Audio cannot parse RIFF MIDI, and Windows' MME cannot process QuickTime containers. Converting RMI to MOV bridges this divide, making Windows-authored MIDI content accessible to Apple's professional video tools.
MOV is the native container for iPhone and iPad video recordings and the default import format for Final Cut Pro. Rendering RMI audio into MOV enables seamless integration with Apple video production workflows — the audio appears as a native timeline clip without format conversion within the NLE.
Common Use Cases
- Importing rendered Windows game RMI soundtracks into Final Cut Pro video timelines
- Creating audio-only MOV files from Windows kiosk RMI music for Apple Keynote presentations
- Preparing legacy Windows training audio from RMI for iMovie projects on macOS and iOS
- Porting Windows multimedia project audio from RMI to MOV for Apple Motion template integration
- Providing rendered Windows-era MIDI compositions as MOV files for Apple-ecosystem collaborators
How It Works
FFmpeg extracts the MIDI data chunk from the RIFF MIDI container and synthesizes audio using a SoundFont-based engine. The PCM output is encoded using AAC-LC (the standard QuickTime audio codec) or ALAC for lossless preservation. The encoded stream is packaged in a MOV container with proper QuickTime atom structure — ftyp set to 'qt ', moov with track and media atoms, and mdat with encoded audio. MOV and MP4 share ISO Base Media File Format lineage, but MOV supports Apple-specific extensions like timecodes.
Quality & Performance
MOV is a container that does not affect audio quality beyond the chosen codec. AAC at 256 kbps in MOV delivers transparent quality for synthesized MIDI content. ALAC in MOV provides lossless preservation. The SoundFont quality determines the musical character — a SoundFont matching the Microsoft GS Wavetable Synth character will produce results closer to how the RMI originally sounded on Windows.

Tips for Best Results
- 1Use AAC at 256 kbps for MOV files destined for Final Cut Pro — this is the standard Apple production audio codec
- 2Choose ALAC encoding if the MOV audio will undergo further processing or remixing after import into a video editor
- 3Render at 48 kHz to match video production standards and avoid sample rate conversion in the NLE timeline
- 4Migrate RIFF INFO metadata from the RMI (title, artist) to MOV metadata atoms for organized project management
- 5Consider M4A instead of MOV unless you specifically need the QuickTime container for a video editing workflow
RMI to MOV bridges the Windows RIFF MIDI world into Apple's professional video ecosystem. This is the natural conversion when legacy Windows MIDI content must integrate with Final Cut Pro or iMovie workflows.
