Both VOB and MPEG are file holders used for holding videos. They both have the same purpose but VOB and MPEG vary in many parameters.


The difference between VOB and MPEG is the areas where they are used. Both are used as video holders but have different applications in areas. MPEG is focused to be used in portable devices and has a portable format while VOB is used in areas of DVD players and discs. VOB has numerous features that are not available in MPEG.

VOB is a video file holder of the videos which are in the format of DVD players. They consist of many elements in them like video, audio, subtitles and compose them together into a single video holder.

They also have extensions through which videos of other formats can be contained in them. But they are specially made for DVD players and discs only.

MPEG is not like a video holder but more of a video standard. MPEG does have many features like VOB and the main functions of MPEG are the compression of audio and video according to our needs.

MPEG has great support for streaming videos of high quality through other streaming sites like YouTube which is not available in VOB.

Parameters of ComparisonVOBMPEG
Area of applicationVOB is generally used in DVD players or videos.MPEG is generally used in a portable format.
CodecsIn comparison to MPEG, VOB can support fewer codecs. In comparison to VOB, MPEG can support more codecs.
SubtitlesVOB has the option of displaying subtitles.MPEG does not have the feature of adding subtitles.

What is VOB?

VOB is the video holder of the DVD format. It contains audio, video, DVD menus, subtitles, etc. Files that are in the VOB have an extension name at the end called “.vob”.

This unique file name distinguishes the other files that are stored in some other formats. VOB has many additional outstanding features in comparison to the MPEG.

VOB supports many files format but has some restrictions in terms of audio and video compression. Since VOB only support files of the DVD format, the quality and size are also minimum restricted to the quality of the DVD content.

VOB supports DVD format files of only 1 GB or less than that. It does not support any files that are bigger in size.

Advantages of VOB come up with the disadvantage of being incapable of the stream.

The main objective of VOB is for the distribution of DVD disc players and hence, VOB does not support streaming videos from Youtube or any other streaming websites.

The compatibility and playback feature of VOB is also limited in comparison to the MPEG.

Hence, VOB is quite useful when it comes to storing files of DVD format and usage of tools like high-quality audio, video, and subtitles.

What is MPEG?

MPEG is a file that sets standards for media coding. The full form of MPEG is the moving pictures expert group.

MPEG also supports the compression of audio and video according to the needs of the users of the files.

The format of MPEG is widely used in numerous multimedia systems as the standards of coding or for the purpose of compression.

The files supported by MPEG are vast and supports files like MPEG 1-4, MPEG-4 Part 2, etc. In terms of quality and size, MPEG has an upper hand over VOB as they support more codecs than VOB.

This improvises the quality of the video that they are storing. They can be encoded by different resolutions and also can have different sizes.

Another advantage of MPEG is its capacity of streaming videos from other websites like Youtube. The streaming can be done so easily without much time and procedures.

In addition to this, the compatibility of MPEG is greater and widely used in TV, satellite, cable, etc. MPEG can be played or streamed on many platforms through its extension.

Hence, MPEG is very useful for improved quality, setting standards, and compression of audio and video but lacks the feature of adding subtitles to the video.

Main Differences Between VOB and MPEG

  1. VOB means video object while the full form of MPEG is moving pictures expert group.
  2. VOB has more outstanding features than MPEG.
  3. VOB is restricted in features like compression of audio and video while MPEG is restricted in features like adding subtitles.
  4. VOB does not support files that are larger than 1 GB while there are no limitations like this in the case of MPEG. MPEG supports more files in comparison to VOB.
  5. VOB is the container of videos in the format of DVD while MPEG is used for setting standards and compression of audio and video.
  6. The quality of the picture will be high in MPEG in comparison to the VOB.
