Quick Verdict
Use MPG when…
Keep MPG if you need to maintain DVD-compatible video for disc authoring, or if you're working in a broadcast chain that specifically requires MPEG-2.
Use MP4 when…
Use MP4 for everything else — streaming, sharing, archiving, social media, and device playback. The compression efficiency and universal compatibility make it the clear choice.
MPG vs MP4: Feature Comparison
| Feature | MPG | MP4 |
|---|---|---|
| Video codec | MPEG-1 or MPEG-2 | H.264 (most common), H.265, AV1 |
| Compression efficiency | Low (MPEG-2 ~8 Mbps for DVD) | High (H.264 ~2 Mbps for same DVD quality) |
| Maximum resolution | 720×576 (PAL DVD) | 4K, 8K |
| Device compatibility | Limited — needs codecs on modern devices | Universal — native on all platforms |
| Streaming support | None | Full — HLS, DASH, HTML5 |
| File size (1 hr SD video) | ~3–8 GB | ~700 MB–2 GB |

Frequently asked questions
Is MPG better quality than MP4?
No. MPG uses older MPEG-2 compression that requires higher bitrates to achieve the same quality as H.264 in MP4. A 4 Mbps H.264 MP4 typically looks better than an 8 Mbps MPEG-2 MPG.
Can I play MPG files on a modern TV?
Modern smart TVs may or may not support MPEG-2 playback natively. Most Blu-ray players do. Sticks (Chromecast, Fire Stick) generally don't support MPEG-2. Convert to MP4 for guaranteed compatibility.
