Why Convert MPG to AAC?
MPG (MPEG) is a legacy video format from DVDs, TV recordings, and older camcorders. The audio track inside an MPG file is typically MPEG-1 Layer II (MP2) — a codec that predates MP3 and is less efficient than modern alternatives. Extracting the audio as AAC gives you a smaller, higher-quality file that plays natively on iPhones, iPads, Android devices, and all modern streaming platforms. AAC at 128 kbps sounds noticeably better than MP2 at the same bitrate.
MPG Audio (MP2) vs AAC
| Feature | MP2 (inside MPG) | AAC (output) |
|---|---|---|
| Era | 1993 (MPEG-1 standard) | 1997 (MPEG-2/4 standard) |
| Compression efficiency | Baseline | ~30% better than MP2 |
| Quality at 128 kbps | Acceptable | Very good |
| Apple device support | ❌ | ✅ Native |
| Streaming platform support | ❌ | ✅ (YouTube, Spotify, Apple Music) |
| Typical use | DVD, broadcast TV | Music, podcasts, streaming |
Use Cases
- DVD audio extraction — Pull the soundtrack from DVD rips stored as MPG files and save as AAC for portable listening.
- TV recording audio — Extract audio from recorded TV shows or broadcasts for podcast-style listening.
- Legacy video archives — Convert old family video audio tracks to a modern format before the MPG files become unplayable.
- Music from video — Extract concert or music video audio from MPG recordings.
Does this extract the audio from the video?
Yes. The converter decodes the audio stream from the MPG container (typically MP2 or AC3) and re-encodes it as AAC. The video track is discarded.
What Quality Preset should I use?
For music, "Very High" or "Highest" preserves the most detail. For speech (TV dialogue, lectures), "High" or "Medium" is sufficient and produces smaller files.
Can I extract audio from both .mpg and .mpeg files?
Yes. Both extensions refer to the same MPEG video format. The converter accepts either.
Will the AAC file be smaller than the original MPG?
Significantly smaller. The MPG file contains both video and audio data. The AAC output contains only the audio track, which is typically 5–10% of the original file size.
Can I trim to extract just one scene's audio?
Yes. Use the Trim option to set a start time and duration in seconds or HH:MM:SS.sss. Only the audio from the selected segment is extracted and converted.
