MIDI (.midi) serves as the underlying data format for virtually every digital music creation tool on the market — from professional DAWs like Logic Pro and Ableton Live to free notation software like MuseScore. When a composer writes music in any of these tools, the internal representation closely follows MIDI event structures even when the software uses proprietary project formats. Exporting as .midi creates a universally portable snapshot of the composition.
MOV is Apple's QuickTime multimedia container, the native video format for all Apple production software. Converting MIDI to MOV renders the composition through software synthesis and packages the audio in a QuickTime container, creating content that integrates natively with Final Cut Pro, iMovie, Keynote, and the entire Apple creative suite without any compatibility friction.
Video producers working in Final Cut Pro frequently need background music, soundtrack beds, or transition stingers for their projects. Composing these elements as MIDI provides maximum creative flexibility — changing tempo, key, or instrumentation takes seconds. Converting the final MIDI to MOV creates a timeline-ready audio asset that drops directly into the Final Cut Pro project without format conversion or re-linking.
Keynote presenters creating professional presentations with custom music can convert MIDI compositions to MOV for seamless integration. Keynote handles MOV natively with precise timing control, allowing presenters to synchronize music with slide transitions and animations — something that would be impossible with raw MIDI files, which Keynote cannot play.
FFmpeg parses the .midi file and synthesizes audio through the SoundFont engine, producing stereo PCM. The audio is encoded as AAC-LC (QuickTime's standard audio codec) or ALAC (for lossless preservation) and packaged in a MOV container. The MOV uses Apple's QuickTime atom structure: ftyp (file type 'qt '), moov (movie atom containing mvhd, trak with mdia, minf, stbl sample tables), and mdat (media data). The edit list (elst) atom is populated to support gapless playback, and the udta atom stores metadata (title, artist, copyright) in Apple's proprietary iTunSMPB format.
MOV is a transparent container — audio quality depends on the codec within. AAC at 256 kbps provides transparent quality matching Apple's distribution standards. ALAC provides bit-perfect lossless preservation. For video production workflows, the SoundFont choice should consider the video's mood and style: corporate videos need clean, professional instrument sounds; indie films benefit from character-rich, slightly imperfect renderings; children's content requires bright, cheerful timbres.
