Understanding VOB and WEBM Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

DVD Video Object

video/dvd

VOB (Video Object) is the container format used on DVD-Video discs, containing multiplexed MPEG-2 video, audio (AC3, DTS, or MPEG), subtitles, and navigation data. Each VOB file typically represents a portion of the DVD content, with files limited to approximately 1 GB due to the UDF filesystem used on DVDs. VOB files can include copy protection data such as CSS encryption.

Advantages

  • Standard format for DVD-Video ensuring universal DVD player compatibility
  • Supports multiple audio tracks, subtitle streams, and navigation menus
  • Well-established format with decades of player and software support

Limitations

  • MPEG-2 video compression is inefficient by modern standards
  • CSS copy protection can prevent direct playback or conversion
  • Limited to DVD resolution (720x480 NTSC or 720x576 PAL)

Common Uses

  • DVD-Video disc content storage and playback
  • DVD ripping and backup operations
  • Legacy video archival from DVD collections

Target Format

WebM Video

video/webm

WebM is an open, royalty-free multimedia container format developed by Google, designed specifically for web video delivery. It contains VP8 or VP9 video codecs with Vorbis or Opus audio, and is natively supported by all major web browsers. WebM offers competitive compression efficiency while avoiding patent licensing requirements.

Advantages

  • Royalty-free and open-source with no licensing costs
  • Natively supported in all major web browsers for HTML5 video
  • Good compression efficiency with VP9 codec rivaling H.264

Limitations

  • Limited hardware decoding support compared to H.264/MP4
  • Not widely supported by video editing software for source editing
  • VP9 encoding is significantly slower than H.264 encoding

Common Uses

  • HTML5 web video delivery as an open alternative to MP4
  • YouTube video streaming (VP9 encoded WebM)
  • Royalty-free video content where licensing is a concern
