MPEG vs MP4

What Is MPEG?

MPEG is a popular video format known for its high compression ratio and fast streaming and downloading speeds. The item MPEG is the acronym of Moving Picture Experts Group, which is a group full of authorities (formed by ISO and IEC) working on setting standards for audio and video compression and transmission.

The MPEG format uses the .mpeg/.mpg file extension and can compress video files without losing too much quality. According to research, MPEG is widely used for online movies and Internet video distribution because of its efficient compression and fast transmission speed.

What Is MP4?

MP4 is a popular digital multimedia container format widely used for storing and streaming video and audio files. This format also known as MPEG-4 Part 14 (which is part of MPEG-4), is a very popular and modern digital multimedia container format. The suffix of MP4 files is .mp4.

Like MPEG, MP4 can store both video and audio data. In addition, it also supports subtitles, still images, and Internet streaming. MP4 is commonly used for movies, online videos, and portable media players, which is why many devices are advertised as MP4 players.

MP4 vs MPEG, Which Is Better?

MP4 is generally better than MPEG for modern video storage, streaming, and device compatibility. The main MPEG standards include MPEG-1, MPEG-2, etc., while MP4 is just developed based on the more recent MPEG-4 standard. This standard is used widely to store videos (and audios) on storage devices like computers and mobile phones.

  • MPEG-1: This standard is mainly used to compress VHS-quality raw video and CD audio down to 1.5 MB/s. The compression is welcomed since not much quality is lost during the process. In general, the video data of MPEG-1 is 30 fps (frames per second) while the resolution is about 352×240.
  • MPEG-2: This standard is mainly used to compress video and audio for higher-quality videos. So it’s often used as a compression scheme for over-the-air digital television, satellite TV services, digital TV, and DVD Video. In general, the video data of MPEG-2 is 30 fps (frames per second) while the maximum resolution is about 720×480.
  • MPEG-4: This standard is mainly used to compress AV data for web (streaming media) and CD distribution, voice (telephone, videophone), and broadcast television applications.

The main difference between MPEG-1 and MPEG-2 is that the bitrates of videos & audios capturing by MPEG-2 are much higher (about 6 MB/s) than that capturing by MPEG-1 (about 1.5 MB/s). Therefore, MPEG-2 is considered an enhanced version of MPEG-1.

The main difference between MPEG-4 and other MPEG standards is the ability to store subtitles, still images, and other kinds of data.

The relationship between them is that MP4 is one of the containers for MPEG-4 videos; another popular container is MKV. You may click here to know more about MPEG-4 vs MP4.

As a result, you should choose MPEG over MP4 if you want to back up videos on a CD or DVD. Otherwise, you may want to convert videos from MPEG to MP4 to use them on mobile devices conveniently; MP4 is more popular (supported by more smartphones and portable media players).
