Understanding VOB and F4V 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

Flash MP4 Video

video/mp4

F4V is an Adobe Flash-compatible video container format based on the ISO base media file format (similar to MP4). Unlike the older FLV format, F4V supports H.264 video and AAC audio, providing significantly better quality and compression. F4V was introduced by Adobe to bring modern codec support to Flash Player before its eventual discontinuation.

Advantages

  • Better quality than legacy FLV using H.264 and AAC codecs
  • Based on the ISO base media file format, similar to MP4
  • Can often be played by renaming to .mp4 on modern players

Limitations

  • Obsolete format associated with discontinued Flash Player
  • Virtually identical to MP4 with no practical advantages
  • Limited software support as a distinct format from MP4

Common Uses

  • Legacy Flash-based video content from streaming sites
  • Migration of older Flash video archives to modern formats
  • Historical web video content originally delivered via Flash Player
