MPG files contain MPEG-1/MPEG-2 video with MP2 audio — the standard codec pairing for DVDs, Video CDs, and digital TV recordings. ALAC (Apple Lossless Audio Codec) provides lossless compression that preserves every decoded sample while achieving roughly 50% file size reduction compared to raw PCM. Converting MPG to ALAC extracts the MP2 audio, decodes it, and re-encodes it losslessly in Apple's format for seamless integration with iTunes, Apple Music, and the wider Apple ecosystem.
ALAC is the native lossless format for Apple's ecosystem. If you want to preserve audio from MPG sources (DVD rips, VHS digitizations, broadcast recordings) in the highest possible quality while keeping files manageable in size and fully compatible with iTunes, Apple Music, iPhone, and HomePod, ALAC is the optimal choice. It avoids the massive file sizes of AIFF while preserving every decoded audio sample.
FFmpeg decodes the MP2 audio from the MPG container to raw PCM, then encodes it using the ALAC codec and wraps it in an M4A (MPEG-4 audio) container. ALAC compression reduces file sizes to approximately 50-70% of the equivalent raw PCM data while guaranteeing bit-perfect reconstruction. The M4A container supports full iTunes metadata including artist, album, artwork, and chapter markers.
ALAC encoding is mathematically lossless — the decoded MP2 audio is preserved perfectly. The output quality equals the original MP2 decode. While ALAC cannot restore detail lost in MP2 compression, it ensures no further degradation occurs, even after repeated editing and re-saving.
