Convert AIFC to MOV — Free Online Converter

AIFC (AIFF-C) is Apple's compressed audio interchange format from the classic Mac OS era, the predecessor to modern Apple audio formats. MOV (QuickTime Movie) is Apple's flagship multimedia container, developed alongside QuickTime in 1991 and still used extensively in professional video production, Final Cut Pro, and Apple's media pipeline.

Converting AIFC to MOV produces an audio-only MOV file — the AIFC audio is decoded and placed in Apple's QuickTime container without a video track. This is relevant for Final Cut Pro timelines, QuickTime-based workflows, and Apple broadcast infrastructure that expects MOV format input.

Final Cut Pro and Apple's professional media tools work most natively with MOV containers. While they can import various audio formats, MOV audio tracks integrate seamlessly into timelines without transcoding delays or import warnings. AIFC, particularly MACE-compressed variants, may not import at all in modern Final Cut Pro.

MOV also supports features important for professional production — precise timecode, multiple audio tracks, and metadata fields used by broadcast infrastructure. Converting AIFC to MOV prepares legacy audio for professional Apple-based post-production workflows where QuickTime is the native container format.

FFmpeg decodes the AIFC container to raw PCM samples and encodes the audio as AAC-LC, ALAC, or PCM within the MOV (QuickTime) container. The MOV format uses Apple's atom-based structure (moov, mdat, trak) to organize the media. For PCM audio, the data is written as little-endian or big-endian depending on the codec tag. The timecode track and edit list atoms enable frame-accurate synchronization in editing timelines.
