MOV (QuickTime Movie) is Apple's multimedia container, closely related to M4A since both derive from the ISO Base Media File Format. Converting M4A to MOV is essentially a container swap within Apple's ecosystem — the AAC or ALAC audio moves from an M4A wrapper to a MOV wrapper. This is relevant for professional video workflows where Final Cut Pro, Motion, and Compressor expect MOV-packaged media for import into timelines.
Final Cut Pro and other Apple pro tools sometimes handle MOV containers differently than M4A. Broadcast delivery specifications may require audio in MOV format. QuickTime Player on macOS provides better editing tools (trim, split) for MOV files than M4A. Some automated video production pipelines only accept MOV input regardless of whether the content is audio or video.
FFmpeg copies the AAC or ALAC audio stream from the M4A container into a MOV container. Both formats use QuickTime-compatible atom structures (moov, mdat, trak), so the conversion is essentially a header rewrite. The audio bitstream remains identical. MOV and M4A are so similar that many tools treat them interchangeably — the main difference is the file extension and brand code in the ftyp atom.
Zero quality change. The audio stream is copied bit-for-bit between containers. MOV and M4A use the same underlying structure — this is a container relabel operation.

M4A to MOV is a simple container swap for Apple's professional video tools. The audio content is unchanged — only the container label and ftyp brand code differ.
