Understanding VOB and AVI 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

AVI Video

video/x-msvideo

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows framework. It stores video and audio data interleaved together and supports a wide variety of codecs. While AVI is a mature and widely supported format, it lacks many features found in modern containers such as native streaming support and variable frame rates.

Advantages

  • Very wide compatibility with both old and new media players
  • Simple container structure that is easy to process
  • Supports virtually any video and audio codec combination

Limitations

  • No native support for variable frame rate or modern streaming features
  • Poor subtitle and metadata support compared to MKV or MP4
  • Older container design lacks advanced features like chapters

Common Uses

  • Legacy video file storage and archival
  • Video capture from older software and hardware
  • Simple video editing and offline playback
