Web Videos Won't Burn to DVD?

You downloaded a video from the web in WebM format, but your DVD authoring software won't recognize it. WebM is optimized for browsers and streaming—not for physical media. DVD players expect VOB files with MPEG-2 video encoding.

Converting WebM files to VOB gives you DVD-compatible video that works with any disc burning software and plays on every standalone DVD player. In our testing, converted files work perfectly with popular authoring tools like DVD Styler, ImgBurn, and Nero.

How to Convert WEBM to VOB

  1. Upload your WebM file – Drag and drop or select your web video
  2. Select VOB output – Choose VOB as your target DVD format
  3. Download your VOB – Get your DVD-ready video file instantly

No software installation needed. Convert right in your browser and start authoring your DVD immediately.

WEBM vs VOB: Format Differences

These formats serve completely different purposes:

FeatureWEBMVOB
Primary UseWeb streamingDVD video storage
Video CodecVP8/VP9MPEG-2 or MPEG-1
Audio CodecVorbis/OpusAC-3, MPEG, PCM, DTS
Browser SupportChrome, Firefox, Edge, SafariNo native support
DVD Player SupportNoneUniversal
Max ResolutionUp to 4K+720x576 (PAL) or 720x480 (NTSC)
File Size LimitNone1GB per file (DVD spec)

WebM uses Google's royalty-free VP8/VP9 codecs for efficient web delivery, while VOB contains MPEG-2 video specifically designed for DVD playback with menu support and chapter markers.

When You Need This Conversion

Creating Physical Archives

Downloaded important videos from YouTube or other platforms in WebM? Convert to VOB and burn to DVD for long-term physical storage. DVDs last decades when stored properly and don't depend on internet access or streaming services staying online.

Sharing with Non-Technical Family

Not everyone knows how to play WebM files on a computer. Burning a DVD is foolproof—insert disc, press play. Perfect for sharing wedding videos, family recordings, or vacation footage with grandparents.

Event Videography

Edited a ceremony or performance in WebM format? Clients often want DVDs as physical keepsakes. VOB gives you the industry-standard format for professional DVD authoring.

Presentation Backup

Need a failsafe for an important presentation? DVD playback doesn't require internet, specific software, or compatibility checks. If the venue has a DVD player, your video plays—guaranteed.

Technical Quality Explained

VOB uses MPEG-2 compression, which is less efficient than WebM's VP9 codec. In our testing, VOB files are typically 2-3 times larger than the equivalent WebM at similar visual quality. This is normal and expected—MPEG-2 dates from 1995, while VP9 was released in 2013.

The resolution also changes during conversion. DVD video is limited to 720x576 pixels (PAL) or 720x480 pixels (NTSC). If your WebM is 1080p or 4K, it will be downscaled to fit DVD specifications. For most viewing distances on a TV screen, this looks perfectly acceptable.

Audio gets transcoded to AC-3 (Dolby Digital) or MPEG audio, both standard DVD audio formats. Quality remains high—DVD audio supports up to 48kHz sampling, which exceeds CD quality.

DVD Authoring After Conversion

Once you have your VOB file, you'll need DVD authoring software to create a playable disc. The VOB file contains your video content, but a complete DVD also needs:

  • IFO files – Navigation and menu information
  • BUP files – Backup copies of IFO files
  • VIDEO_TS folder structure – The standard DVD directory layout

Free tools like DVD Styler, DVDFlick, or Bombono DVD handle this automatically. Import your converted VOB, add menus if desired, and burn directly to disc.

Alternative Formats to Consider

VOB isn't your only option for physical media or offline playback:

  • WEBM to MPG – Creates MPEG files compatible with older DVD software
  • WEBM to AVI – Widely supported, good for Windows-based systems
  • WEBM to MP4 – If you want universal playback without burning to disc

Choose VOB specifically when your end goal is a playable DVD disc. For USB drives or media players, MP4 is usually the better choice.

Browser-Based Processing

Our converter works entirely in your web browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No software downloads required
  • Files stay on your device during processing

Upload your WebM, get your VOB. No accounts, no watermarks, no waiting for server processing queues.

Pro Tip

For best DVD quality from WebM sources, start with the highest quality WebM available. DVD resolution is only 720x480/576, but higher source quality means cleaner downscaling with less compression artifacts visible in the final VOB.

Common Mistake

Assuming one VOB file equals one playable DVD. VOB is just the video container—you still need DVD authoring software to generate IFO navigation files and the proper VIDEO_TS folder structure before burning.

Best For

Creating physical DVD archives of downloaded web videos, making shareable discs for family members who prefer DVD players over streaming, and providing video for venues or clients that specifically request DVD format.

Not Recommended

If your goal is sharing video online or playing on computers/phones, skip VOB entirely. Convert WebM to MP4 instead—it's universally supported and doesn't require DVD authoring. VOB is only worth the extra steps when physical disc playback is the actual requirement.

Frequently Asked Questions

VOB (Video Object) is the container format used on DVD-Video discs. It contains MPEG-2 video, audio tracks (AC-3, DTS, or PCM), subtitles, and menu data. VOB files are stored in the VIDEO_TS folder on DVDs and are limited to 1GB each per DVD specification.

DVD players can only read MPEG-2 video in VOB containers. WebM uses VP8/VP9 codecs that DVD hardware doesn't support. Converting to VOB transcodes the video to MPEG-2, making it compatible with all DVD players manufactured since the late 1990s.

Some quality loss is inherent when transcoding between different codecs. However, for DVD viewing on a TV screen at normal distance, the difference is rarely noticeable. VOB files use MPEG-2 at DVD-standard resolutions (720x480 or 720x576), which looks great on standard-definition displays.

VOB files follow DVD specifications: 720x480 pixels for NTSC (North America, Japan) or 720x576 for PAL (Europe, Australia). If your WebM is higher resolution, it will be downscaled during conversion to meet these standards.

You'll need DVD authoring software to create a playable disc. The software generates required IFO navigation files and creates the proper VIDEO_TS folder structure. Free tools like DVD Styler or DVDFlick can do this easily with your converted VOB.

VOB files are typically 2-3 times larger than equivalent WebM files. MPEG-2 compression is less efficient than VP9. A 100MB WebM might become a 250-300MB VOB file. Ensure you have sufficient storage for the converted video.

WebM is designed for web sharing and streams efficiently in browsers. VOB is strictly for DVD playback and isn't supported by web browsers. Keep your original WebM for online sharing; use VOB only when creating physical DVDs.

Yes, batch conversion is supported. Upload multiple WebM files and convert them all to VOB in one session. Each becomes a separate VOB file you can later combine in your DVD authoring software.

Yes. Game consoles with DVD playback capability can read standard VOB files from burned DVDs. PlayStation 2, 3, 4, and Xbox 360 all support DVD video playback, as do many Xbox One models with the Blu-ray app.

NTSC (29.97fps, 720x480) is used in North America and Japan. PAL (25fps, 720x576) is standard in Europe, Australia, and most of Asia. Most modern DVD players are multi-region and play both formats, but check your target player if unsure.

Our browser-based converter handles typical web video file sizes. For very long videos, you may want to split them before conversion since individual VOB files on a DVD must be under 1GB each.

Subtitles need to be added during DVD authoring, not during the video conversion. Convert your WebM to VOB first, then use DVD authoring software to add subtitle tracks from SRT or SUB files before burning the disc.
