Om konvertering fra MPG til ALAC

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.

Hvorfor konvertere MPG til ALAC?

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.

Slik fungerer det

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.

Kvalitet og ytelse

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.

Tips for best resultat

1Use ALAC for Apple-centric libraries and FLAC for cross-platform archiving — the audio quality is identical
2The M4A container supports iTunes metadata — add artist, album, and artwork after conversion for a complete library entry
3For large MPG collections (e.g., complete DVD sets), batch convert to ALAC to save time while preserving quality
4If the MPG has multiple audio tracks (e.g., director commentary on a DVD), extract each track to a separate ALAC file
5Verify the original MP2 bitrate first — low bitrate MP2 (128 kbps) audio may not warrant lossless archiving since the source is already heavily compressed

MPG to ALAC conversion brings legacy broadcast and disc audio into Apple's lossless ecosystem. The combination of lossless compression and full iTunes/Apple Music compatibility makes it the ideal archival format for Apple users.

Ofte stilte spørsmål

Yes, ALAC losslessly preserves the decoded MP2 audio. The only quality limitation comes from the original MP2 compression — ALAC itself introduces zero additional loss.

ALAC files contain only audio (no video) so they are much smaller than the full MPG. Compared to raw PCM, ALAC is roughly half the size. Compared to the original MP2, ALAC is typically 3-5x larger since MP2 is a lossy codec.

Android 3.1+ includes ALAC decoding support. However, FLAC has broader and more reliable support on Android devices and apps.

Both are lossless with identical quality. ALAC integrates better with Apple devices; FLAC is more universal and open-source. Choose based on your primary ecosystem.

DVD chapter markers are in the video stream, not the audio. They will not transfer to the audio-only ALAC output. Chapter markers would need to be manually added in iTunes.
