ALAC stores lossless audio in Apple's M4A container. OGV (Ogg Video) is Xiph.org's open-source multimedia container, typically containing Theora video and Vorbis audio. Converting ALAC to OGV leverages lossless source quality for optimal Vorbis encoding.
Since ALAC decodes to perfect PCM, the Vorbis encoder in OGV receives the best possible input — producing optimal quality with only a single lossy step.
Some open-source platforms (Wikimedia Commons) and Linux-based workflows require OGV format. Converting ALAC to OGV creates royalty-free video content with high-quality Vorbis audio from a lossless Apple source.
The lossless starting point means Vorbis quality in OGV is the best achievable for the quality level — noticeably better than transcoding from MP3 or AAC.
FFmpeg decodes ALAC to perfect PCM and encodes to Vorbis within an OGG container with .ogv extension. A static image is added as the Theora video stream. The lossless decode ensures only one lossy step occurs, producing optimal Vorbis quality.
Vorbis at quality 5 (~160 kbps) from ALAC produces transparent audio for most listeners. The lossless source ensures better Vorbis output than from any lossy source format.
