Why Convert VOB to MP4?
VOB (Video Object) is the container format used on DVDs, storing MPEG-2 video along with audio tracks, subtitles, and menu data. While VOB files play fine in VLC and dedicated DVD software, they're incompatible with most modern devices, streaming platforms, and social media. A single DVD can contain multiple VOB files totaling 4–8 GB, making them impractical to share or store without conversion.
MP4 with H.264 encoding is the universal standard — it plays on every phone, tablet, computer, smart TV, and web browser. Converting VOB to MP4 typically reduces file size by 50–70% while maintaining visual quality, because H.264 is far more efficient than the MPEG-2 codec used in DVDs.
Common use cases include digitizing a DVD collection for streaming on Plex or similar media servers, extracting a scene from a DVD for sharing, or archiving home video DVDs before the discs degrade.
VOB vs MP4 Comparison

| Device compatibility | DVD players, VLC | Universal — phones, browsers, TVs |
| Streaming support | ❌ No | ✅ Yes |
| Multiple audio tracks | ✅ Yes | ✅ Yes |
| Subtitle support | ✅ Embedded | ✅ Embedded or external |
| Quality at same file size | Lower (older codec) | Higher (modern compression) |
Frequently Asked Questions
Will converting VOB to MP4 lose quality?
Some re-encoding is required since VOB uses MPEG-2 and MP4 typically uses H.264. However, at the default quality setting (CRF 23) or higher, the difference is visually imperceptible. For the best quality, use CRF 18 — this produces a visually lossless result at a larger file size.
Can I convert multiple VOB files from a DVD at once?
Yes. DVDs typically split movies across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Upload all of them and XConvert will convert each one to MP4. If you want to merge them into a single file, convert them first and then use our Merge Video tool.
How much smaller will the MP4 file be?
Typically 50–70% smaller than the original VOB. A 4.5 GB DVD VOB file usually converts to a 1.5–2 GB MP4 at high quality, or under 1 GB at medium quality.
Can I keep the DVD subtitles when converting to MP4?
XConvert preserves the primary audio track during conversion. For subtitle handling, the subtitles embedded in VOB files are bitmap-based (not text), so they may not carry over to MP4 in all cases. For full subtitle preservation, consider converting to MKV instead using our VOB to MKV converter.
What resolution should I use for DVD VOB files?
Standard DVDs are 720×480 (NTSC) or 720×576 (PAL). There's no benefit to upscaling beyond the source resolution. Keep the original resolution or use the 480p preset for the most accurate conversion.
