About MPG to FLAC Conversion
MPG files carry MPEG-1/MPEG-2 video with MP2 (MPEG Audio Layer 2) audio — the audio codec standard for DVDs, VCDs, and digital TV broadcasts at typical bitrates of 128-384 kbps. FLAC (Free Lossless Audio Codec) is an open-source lossless compression format that preserves every decoded sample while reducing file sizes by 30-50% compared to raw PCM. Converting MPG to FLAC extracts and decodes the MP2 audio, then encodes it losslessly in FLAC for archival or editing purposes.
Why Convert MPG to FLAC?
FLAC is the universal standard for lossless audio archiving across all platforms. If you have valuable audio in MPG files — concert recordings, broadcast audio, DVD soundtracks — converting to FLAC preserves the decoded MP2 audio perfectly while providing efficient compression and full metadata support. FLAC is supported natively on Linux, Android, Windows, and macOS (since High Sierra).
Common Use Cases
- Archiving DVD soundtrack audio in lossless quality for preservation
- Extracting broadcast recording audio for professional editing without codec overhead
- Preserving digitized VHS tape audio (captured as MPG) in a lossless, open format
- Creating reference audio files from TV capture recordings for content analysis
- Building a lossless audio collection from concert DVDs and music video collections
How It Works
FFmpeg decodes the MP2 audio stream from the MPG container to raw PCM samples, then encodes them using the FLAC encoder. FLAC compression levels range from 0 (fastest, largest) to 12 (slowest, smallest), with level 5 being the default sweet spot. Output files include Vorbis comment metadata. The FLAC encoding is completely lossless — the decoded PCM samples can be reconstructed bit-for-bit from the FLAC file.
Quality & Performance
FLAC perfectly preserves the decoded MP2 audio with zero additional loss. The output quality is exactly what you would hear when playing the original MPG file. FLAC cannot improve upon the original MP2 encoding, but it ensures no further degradation occurs during storage, copying, or subsequent editing.

Tips for Best Results
- 1FLAC compression level 5 is the recommended default — higher levels produce marginally smaller files at significantly slower speeds with no quality difference
- 2Preserve the original sample rate (typically 48 kHz for DVD, 44.1 kHz for VCD) unless your workflow requires resampling
- 3If the MPG contains multiple audio streams (common on DVDs), convert each to a separate FLAC file
- 4Add metadata tags (ARTIST, ALBUM, TRACKNUMBER) after conversion for organized library management
- 5For very large DVD collections, FLAC's efficient compression saves significant storage compared to AIFF or WAV
