Understanding WMV and VOB Formats

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

Source Format

WMV Video

video/x-ms-wmv

WMV (Windows Media Video) is a proprietary video compression format developed by Microsoft, based on the Advanced Systems Format (ASF) container. It was designed for streaming and local playback on Windows platforms and includes built-in DRM support for content protection. WMV has largely been superseded by H.264/MP4 for most modern use cases.

Advantages

  • Good compression efficiency, especially at low bitrates
  • Native support in Windows Media Player and Windows ecosystem
  • Built-in DRM support for protected content distribution

Limitations

  • Proprietary format with poor cross-platform compatibility
  • Not supported on iOS, many Android players, or web browsers without plugins
  • Declining usage and relevance in modern video workflows

Common Uses

  • Legacy Windows video libraries and media collections
  • DRM-protected video content from older platforms
  • Windows-based screen recordings and presentations

Target 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
