What is VOB?

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

What is HEVC?

Raw H.265/HEVC is an elementary stream of High Efficiency Video Coding data, doubling compression efficiency over H.264.

When Should You Use VOB vs HEVC?

VOB vs HEVC: Key Differences

• •The core technical difference: VOB relies on lossy compression whereas HEVC 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
• •VOB files are typically 1-2GB per hour of DVD video while HEVC files range 50% smaller than H.264 at same quality
• •Primary audience: VOB is built for dvd movies, legacy video archives scenarios, while HEVC focuses on high-efficiency video encoding, 4k/8k streams — pick the format that matches your output requirement.

Advantages of VOB

• ✓The lossy nature of VOB means file sizes stay reasonable while handling DVD movies, legacy video archives efficiently.
• ✓From mobile devices to enterprise servers, VOB is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using VOB thanks to its efficient compression.
• ✓VOB is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of HEVC

• ✓HEVC uses lossy compression tailored for High-efficiency video encoding, 4K/8K streams.
• ✓HEVC is supported natively on virtually every device, browser, and operating system.
• ✓HEVC files are compact and quick to transfer, even over slow connections.
• ✓HEVC integrates seamlessly with all major creative tools and workflows.

Common Use Cases for VOB to HEVC Conversion

• Social media content
• Security and surveillance
• Educational content
• Marketing videos
• Video archiving
• Broadcast production

Best Practices for VOB to HEVC Conversion

• →Converting VOB to HEVC: match the output resolution and bitrate to your target platform's requirements
• →HEVC offers efficient streaming-optimized compression — ideal for online delivery
• →Use appropriate bitrate for the balance of quality and file size
• →HEVC is a lossy format, so expect some quality loss at higher compression ratios
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting VOB to HEVC Conversion

• !HEVC won't play on target device → check codec compatibility (H.264 has broadest support)
• !Audio out of sync after VOB to HEVC conversion → try re-muxing with a different container format
• !HEVC quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
• !File size increased converting VOB to HEVC → lossless or higher-bitrate outputs naturally produce larger files
