AIFC (AIFF-C) is Apple's compressed audio interchange format from the late 1980s, a legacy container found almost exclusively in classic Mac OS and NeXTSTEP archives. OGV (Ogg Video) is an open-source multimedia container from the Xiph.org Foundation, designed for web video delivery using the Theora video codec and Vorbis audio codec — both completely patent-free.
Converting AIFC to OGV produces an audio-only OGV file — the audio is encoded as Vorbis and wrapped in the Ogg container with the .ogv extension. This is relevant for open-content platforms like Wikimedia Commons, which historically preferred OGV for all media content, and for legacy web deployments that used OGV before HTML5 video settled on MP4 and WebM.
Wikimedia Commons and other open-content platforms historically required OGV (or WebM) for all uploaded media, including audio-only content. AIFC is not accepted by any open-content platform. Converting AIFC to OGV makes legacy Mac audio compatible with these platforms' patent-free media requirements.
OGV also serves legacy web applications that were built around the Ogg container before WebM became the dominant open format. Some institutional and educational web systems deployed Ogg-based media infrastructure that remains operational. AIFC cannot be used in any of these systems.
FFmpeg decodes the AIFC container to raw PCM samples and encodes the audio using libvorbis (variable bitrate, quality levels -1 to 10). The encoded Vorbis bitstream is muxed into an Ogg container with the .ogv extension. No Theora video track is included — the file is audio-only. The Ogg container manages page sequencing and granule positions for sample-accurate seeking.
Audio quality is determined by the Vorbis encoding settings. Quality level 5 (~160 kbps VBR) produces good music quality from uncompressed AIFC PCM. Quality level 7 (~224 kbps) is perceptually transparent for most listeners. The Ogg container adds no quality penalty. MACE-compressed AIFC sources limit the achievable quality regardless of Vorbis settings.

AIFC to OGV places legacy Apple audio in a patent-free Ogg container. This conversion is primarily relevant for open-content platforms and legacy web infrastructure that specifically require OGV format.
