OGV files store Vorbis audio (a lossy open-source codec) within the Ogg video container. ALAC (Apple Lossless Audio Codec) is Apple's lossless compression format that reduces PCM audio to about 50-60% of original size with zero data loss. Open-sourced by Apple in 2011, ALAC plays natively on every Apple device and integrates seamlessly with Apple Music, iTunes, and Apple's professional audio tools.
Extracting OGV audio to ALAC creates a lossless archival copy of the decoded Vorbis audio that integrates perfectly with the Apple ecosystem. While the source is lossy (Vorbis), storing the decoded output as ALAC prevents any further quality degradation during future format conversions or editing.
ALAC is also the best format for importing into Apple Music with the Lossless quality badge, making it ideal for building a music library from OGV video sources.
FFmpeg decodes the OGV container's Vorbis audio to raw PCM, then encodes using the ALAC encoder into an M4A container. The output supports 16-bit to 32-bit depth and sample rates up to 384 kHz. Typical OGV Vorbis audio at 44.1 kHz stereo maps directly to 16-bit/44.1 kHz ALAC. Compression achieves roughly 50-60% of the PCM equivalent size while remaining bit-perfect on decode.
ALAC losslessly preserves the decoded Vorbis audio. Since Vorbis is lossy, the ALAC output contains the same quality as the Vorbis source — no better, no worse. The advantage is that ALAC prevents any further quality loss during subsequent operations while providing meaningful compression savings versus uncompressed WAV or AIFF.
