Difference between VOB and MPEG

If you’re a video editor, at some point you’ll need to know the difference between VOB and MPEG files. Both are container formats for video and audio, but they have different specifications. In this post, we’ll take a look at the differences between VOB and MPEG, so you can choose the right format for your project.

What is VOB?

VOB, or Video Object, is a container format used for storing digital video data. VOB files are typically used for DVD and Blu-ray content, and usually contain video and audio streams as well as other data like subtitles and menu information. VOB files are typically encrypted, which helps to protect the content from unauthorized copying. In order to play a VOB file, you will need a compatible DVD or Blu-ray player. Some media players may also be able to play VOB files, but they may need to be decrypted first. VOB files can also be converted to other video formats using various video converter software.

What is MPEG?

MPEG, or Motion Picture Expert Group, is a working group of engineers that was formed in 1988 with the aim of developing standards for digital compression and coding of MPEG video and MPEG audio.

  • MPEG video is used in a variety of applications, such as DVDs, broadcast television, and digital signage. MPEG audio is used in CDs, MP3s, and other digital audio applications.
  • MPEG has also developed standards for 3DTV and Ultra HDTV. In addition to its work on video and audio compression, MPEG also develops standards for other forms of digital media, such as interactivity and streaming.
  • MPEG is an international organization with members from over 100 countries. Its work is carried out by a number of subcommittees, each responsible for a different aspect of the MPEG standard. MPEG is headquartered in Geneva, Switzerland.

Difference between VOB and MPEG

VOB (Video Object) and MPEG (Motion Picture Expert Group) are two different file formats for digital video. VOB is a format used on DVDs and Blu-rays, while MPEG is a format used for digital TV broadcasts and online video streaming.

  • VOB files are larger than MPEG files, but they offer better quality and more features. For example, VOB files can contain multiple audio tracks, subtitles, and menus.
  • VOB files are also better at handling copyright protection and copy protection. Ultimately, the choice of format depends on the intended use of the video.
  • If you want to improve video quality or if you need to include extra features like menus and subtitles, VOB is the better choice. If you need a smaller file size or if you need compatibility with digital TV or online video streaming, MPEG is the better choice.


The MPEG format is often used for streaming video content on the internet, while VOB files are more commonly found on DVDs. If you’re looking to create a DVD master file, then you should use the VOB format. However, if you need to compress a video for online streaming, then the MPEG format is likely a better choice.
