Since majority of the users prefer MP4 format, sometimes we are in need of AVI format as well to watch a particular video and hence we have to convert MP4 to AVI format for the same reason.

Before that, let’s have a look at what exactly are these MP4 and AVI formats and why and how are they different from each other.

Part 1. What are MP4 and AVI Formats?

1.1 Briefing on AVI Format

AVI stands for Audio Video Interleave. Microsoft introduced this multimedia container format as a piece of its technology, Video for Windows. AVI files are capable of containing both video and audio data in one file container that further enables simultaneous “audio along with video” playback. Similar to the DVD video format, features that are hardly used including several streaming of video as well as audio are also supported by AVI files. The AVI format is mainly related with “Audio Video Interleave File”. Current files can be compressed with any one or other codecs such as DivX and XviD. Moreover, it can also be used with DVDFab Player 5, VLC Player, as well as The KMPlayer. Usually, AVI is less compressed as compared to other well-known formats such as MPEG and MOV. This means that any AVI file will be bigger than the similar file in one of these compressed formats.

1.2 Briefing on MP4 Format

MP4, also known as MPEG-4 Part 14, is developed by MPEG and is a container format that uses MPEG-4 compression. The MP4 container enables its users to store mixture of audiovisual data, still image, along with subtitles in just one single file. MP4 video format files generally can be saved with extensions .mp4, while some others include .m4p, .m4a, .3pg, as well as .m4v extensions. Some facts of MP4 are:

  • MP4 format provides high quality of image and sound but lesser quantity of data owing to its far-above-the-ground compression rate
  • The high-level compression gives smaller size. This features makes it stand out as far as streaming is considered
  • MP4 format files can comprise metadata according to the defined format standard. MP4 format files support audio, video as well as subtitles.
  • It saves different data types apart from audio and video, such as, the scene descriptors, the object descriptors, and so on.
