Why Convert VOB to FLV?

VOB files are the video containers found on DVDs, stored in the VIDEO_TS folder. While they contain high-quality MPEG-2 video, VOB files are large, tied to DVD structure, and awkward to share or stream online.

FLV (Flash Video) was the dominant streaming format before HTML5 video took over. While newer than its heyday, FLV remains useful for legacy systems, older media players, and specific archival workflows. Converting VOB to FLV creates smaller, more portable video files that work independently of DVD structure.

How to Convert VOB to FLV

  1. Upload your VOB file - Drag and drop or click to select your DVD video file
  2. Confirm FLV output - FLV is selected as your target format
  3. Download your video - Get your converted Flash video file

The entire process happens in your browser. No software installation, no account creation, no waiting in queues.

VOB vs FLV: Technical Differences

Understanding what changes during conversion helps you know what to expect:

  • Codec - VOB uses MPEG-2 video; FLV typically uses Sorenson Spark or VP6/H.264
  • File size - FLV files are significantly smaller due to more efficient compression
  • Container - VOB is part of DVD-Video structure; FLV is a standalone streaming format
  • Compatibility - VOB requires DVD software; FLV works with Flash-enabled players and many media players

In our testing, a typical 1GB VOB file converts to approximately 200-400MB in FLV format while maintaining acceptable visual quality.

When to Use This Conversion

Archiving DVD Collections

If you're digitizing old DVDs, converting VOB to FLV creates standalone files you can organize and store. Each VOB file becomes an independent video rather than part of a DVD structure. For more modern archiving, consider VOB to MP4 conversion instead.

Legacy Web Projects

Some older content management systems and embedded players still expect FLV files. If you're maintaining legacy systems or working with older video infrastructure, FLV may be required.

Smaller File Sizes

DVD video is uncompressed by modern standards. FLV's compression dramatically reduces file size, making videos easier to store and transfer.

What About Quality?

FLV uses lossy compression, so some quality reduction is inevitable. However, for most viewing purposes, the difference is minimal. DVD video resolution (720x480 or 720x576) translates well to FLV's compression algorithms.

If preserving maximum quality matters more than file size, explore our VOB converter page for alternative output formats like MKV or MP4 that offer better quality-to-size ratios with modern codecs.

Works on Any Device

Our browser-based converter runs entirely client-side:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • Tablets and capable mobile devices

Your VOB files never leave your device during conversion. Processing happens locally in your browser.

Handling Multiple VOB Files

DVDs typically split content across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). You can convert each file individually. For joining them into a single video, you'd need to combine them first using video editing software, then convert the merged file.

For simpler workflows, consider converting to VOB to MKV which handles multiple streams and chapters more elegantly.

Pro Tip

Before converting, check which VOB files contain actual movie content versus menus. VTS_01_*.VOB usually has the main feature, while VIDEO_TS.VOB and VTS_01_0.VOB often contain menus and navigation data you can skip.

Common Mistake

Converting each VOB file separately when you want one continuous video. For a seamless movie, you need to join the VOB files before conversion using video editing software, or choose a format like MKV that handles DVD structure better.

Best For

Archiving DVD content for legacy systems or older media players that specifically require FLV format. Also useful when file size reduction is the priority over maximum quality preservation.

Not Recommended

For modern video workflows, MP4 or MKV are better choices. FLV's compression is outdated compared to H.264/H.265. Only use FLV if you specifically need Flash format for legacy compatibility.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVD-Video discs. VOB files are stored in the VIDEO_TS folder and contain MPEG-2 video, audio tracks, subtitles, and DVD menu data multiplexed together.

FLV (Flash Video) was the primary format for streaming video on the web from the mid-2000s until HTML5 video became standard. It's still used in legacy systems, older media players, and some specialized workflows.

Yes, some quality loss occurs because FLV uses more aggressive compression than DVD's MPEG-2. However, for typical viewing at DVD resolution, the difference is usually acceptable. File sizes drop significantly.

Insert the DVD and navigate to the VIDEO_TS folder. The .VOB files contain the actual video content. You can copy these files to your computer, then upload them for conversion. Note that copy-protected DVDs may require additional steps.

Our converter works with any VOB file you can access on your computer. If your DVD has copy protection, you'll need to handle that separately before conversion. We only process files you provide.

DVDs split video content into 1GB chunks for technical reasons. A 2-hour movie might span 4-6 VOB files (VTS_01_1.VOB through VTS_01_6.VOB). Each can be converted separately.

While Adobe discontinued Flash Player in 2020, FLV files can still be played by VLC, Windows Media Player (with codecs), and most video software. The format remains viable for offline viewing and legacy systems.

For modern use, MP4 is generally better - it offers superior compression and universal device support. FLV makes sense for legacy systems, older embedded players, or specific workflow requirements that demand Flash format.

Conversion time depends on file size and your device's processing power. A typical 1GB VOB file converts in 2-5 minutes on modern computers. Processing happens locally in your browser.

No. Conversion happens entirely in your browser using local processing. Your VOB files never leave your device. This also means conversion works offline once the page loads.
