MPG files carry MPEG-1/MPEG-2 video alongside MP2 (MPEG Audio Layer 2) audio from DVDs, VCDs, and broadcast recordings. M4A is Apple's audio container that wraps AAC audio in an MPEG-4 package, with native support for iTunes metadata, chapter markers, and album artwork. Converting MPG to M4A extracts the audio, upgrades it from MP2 to AAC, and packages it in Apple's standard audio format for seamless integration with iTunes, Apple Music, and all Apple devices.
M4A is the native audio format for Apple's ecosystem — iTunes, Apple Music, iPhone, iPad, Apple Watch, and HomePod all handle M4A natively. MP2 audio from MPG files is a legacy codec that Apple devices do not support in their default music apps. Converting to M4A modernizes the audio codec (MP2 → AAC, a superior codec at all bitrates) and makes the content fully accessible across all Apple products.
FFmpeg extracts and decodes the MP2 audio from the MPG container, then re-encodes it using the AAC encoder and wraps it in the M4A (MPEG-4 audio) container. Typical AAC bitrates are 128-256 kbps, providing quality that matches or exceeds the original MP2 at lower data rates. The M4A container supports full iTunes-style metadata (title, artist, album, artwork, lyrics, chapters).
AAC at 128 kbps typically matches MP2 at 192 kbps in perceived quality. Since this is a lossy-to-lossy transcode, encoding the AAC at a bitrate equal to or higher than the original MP2 minimizes additional quality loss. For most DVD MP2 sources (typically 192-384 kbps), AAC at 192 kbps produces excellent results.

MPG to M4A conversion modernizes legacy broadcast and disc audio for Apple's ecosystem. AAC's superior compression efficiency means smaller files with equivalent quality, wrapped in Apple's feature-rich M4A container.
