What is VOB?

DVD Video Object (VOB) is the container format for DVD-Video discs, containing MPEG-2 video, audio, and subtitles.

What is M2V?

MPEG-2 Video (M2V) is a raw elementary stream of MPEG-2 compressed video, commonly used in DVD and broadcast.

When Should You Use VOB vs M2V?

VOB vs M2V: Key Differences

• •The core technical difference: VOB relies on lossy compression whereas M2V uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Transparency: N/A
• •File sizes: VOB files typically range 1-2GB per hour of DVD video and M2V files Larger than MPEG-1, 3-10Mbps.
• •Use case fit: VOB targets dvd movies, legacy video archives and M2V targets dvd video, broadcast tv, mpeg-2 encoding — your choice depends on which workflow stage you are serving.

Advantages of VOB

• ✓At its core, VOB relies on lossy encoding — a design choice that makes it perfect for DVD movies, legacy video archives.
• ✓You won't run into compatibility issues with VOB — it's a universal standard across platforms.
• ✓File size management with VOB: aggressive compression with minimal visible quality loss.
• ✓Every major application in the DVD movies, legacy video archives space supports VOB natively.

Advantages of M2V

• ✓M2V uses lossy compression tailored for DVD video, broadcast TV, MPEG-2 encoding.
• ✓M2V is supported natively on virtually every device, browser, and operating system.
• ✓M2V files are compact and quick to transfer, even over slow connections.
• ✓M2V integrates seamlessly with all major creative tools and workflows.
