What is VOB?

VOB (Video Object) is the container format for video on DVD-Video discs. When you look at a DVD's VIDEO_TS folder, you'll find VOB files containing the movie's video, audio, subtitles, and menu content.

VOB files use MPEG-2 video and can include multiple audio tracks (Dolby Digital, DTS, PCM) and subtitle streams. The format has been the foundation of DVD movies since the format launched in 1996.

While DVDs remain playable, converting VOB to MP4 creates digital copies for modern devices that lack DVD drives, and provides smaller, more portable files.

Why Convert VOB Files?

VOB conversion is essential for digital DVD archival:

  • No DVD drives - Modern laptops and devices lack optical drives
  • Large file sizes - MPEG-2 uses much more space than modern codecs
  • Mobile playback - Phones and tablets can't play VOB files
  • Streaming - VOB can't be streamed to TVs or Chromecast
  • Preservation - DVDs degrade over time; digital copies last forever
  • Portability - MP4 files can go anywhere, DVDs cannot

How to Convert VOB Files

  1. Upload your VOB file - Drag and drop the VOB file from your DVD's VIDEO_TS folder.
  2. Choose your output format - Select MP4 for universal compatibility, MKV to preserve multiple tracks.
  3. Download converted file - Get your digitized video ready for any device.

Pro Tip

DVDs often split movies across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Convert each separately and join them, or use software that combines them automatically.

Common Mistake

Converting only one VOB file and getting just part of the movie. DVDs split content across multiple VOB files. Make sure to convert all VTS files for the complete movie.

Best For

VOB is the native format for DVD-Video discs. Today it's used for DVD playback and as the source for digitizing DVD collections to more portable formats.

Not Recommended

Don't keep video as VOB files for general use. The format is outdated, huge, and incompatible with modern devices. Convert to MP4 for practical use.

Frequently Asked Questions

VOB (Video Object) is the video format used on DVD discs. VOB files are found in the VIDEO_TS folder and contain the movie's video, audio tracks, and subtitles in MPEG-2 format.

Copy the VOB files from your DVD's VIDEO_TS folder, upload them to ChangeMyFile, select MP4 output, and download. This creates a digital copy of your DVD content.

VOB files use MPEG-2 compression, which is much less efficient than modern H.264. A 2-hour DVD might be 4-8GB in VOB format but only 1-2GB as MP4.

Most phones don't play VOB files. Convert to MP4 for playback on any smartphone. This also reduces file size dramatically.

Minimal quality loss occurs with proper settings. DVDs are already limited to 480p/576p resolution. MP4 conversion at appropriate bitrates preserves this quality in a smaller file.

VOB files are in the VIDEO_TS folder on DVD discs. Insert your DVD, navigate to VIDEO_TS, and you'll see VTS_01_1.VOB and similar files containing the movie.

Converting to MKV format preserves multiple audio tracks and subtitles from your DVD. MP4 typically keeps only the primary audio track.

Converting DVDs you own for personal backup is generally considered fair use in many jurisdictions. However, distributing copies or converting rented/borrowed DVDs may violate copyright laws.

VIDEO_TS is the folder on DVDs containing all video content. It includes VOB files (video), IFO files (navigation info), and BUP files (backups). The actual movie is in the VOB files.
