AVI vs MP4 - Detailed Comparison

As far as the video formats is concerned, we can mention more than 5 kinds of video containers in one time. The video containers with extensions of .flv .f4v .rmvb .mp4 and .avi, etc are all familiar to the users. Due to the different video resolutions and video encoded technology applied on them, the listed video container formats differ with each other dramatically. Some are supported by the designated device while others are not. AVI vs MP4 are on the list of the popular video containers format that a variety of videos are saved with the file extension marking .avi and .mp4. However, these two video containers format are basically different in their file size, compression and quality.

What is AVI vs MP4?

Details about the AVI and MP4 are introduced in the following section.

What is AVI?


AVI is the abbreviation of audio video interleave file. It contains both video and audio data which are saved with the file extension of .avi. This video container format was developed by Microsoft in the year of 1992 thus the format of AVI is compatible with the devices subordinated to Microsoft series such as Windows player and other programs with the related codecs.

What is MP4?


The full explanation of MP4 is MPEG-4 Part 14. Similar as the AVI, MP4 is also a multimedia container format. It was developed by Moving Picture Experts Group. As one of the most frequently-used video container formats, MP4 is compatible with almost all kinds of video players of mobile phones including iPhone, iPad and Android phones and tablets. Most of the MP4 files are saved with the file extension of .mp4 but some are with exceptions to be saved with the file extension of .m4a and .m4p.

Detailed Comparison between AVI vs MP4

As far as the popularity is concerned, both AVI and MP4 share the user all over the world. But there are still lots of differences between them.

Comparison of video quality

If it is hard to distinguish the video quality between AVI and MP4 via the technological method, you can just play both of the videos with the file extension of .avi and .mp4 respectively and rate the video quality by naked eyes. Normally the video in the format of AVI is clearer than the video in the format of MP4 due to the codec they are associated with. AVI is associated with DivX codec, while MP4 uses MPEG-4 AVC/H.264 codec. 

Comparison of file size

Before transforming the original video into a specific video container format, it is compressed to smaller size to some degree. Since the AVI video is compressed at the lower level than the MP4 video does, it is with a larger video size.

For more comparisons between the two video container formats, we list them out in a table.

Quality High quality Excellent quality
Compression Lossy Lossless
File size Small Large
Supported codecs MPEG-1, MPEG-2, MPEG-4, H.264/AVC, H.265/HEVC, WMV/VC-1, Real Video, Theora, VP8, VP9, MVC DivX, XviD
Compatible devices Devices subject to both android and iOS Mostly Microsoft devices and some limited apple devices
Supported players All media players basically Only Windows-based players
Developed by MPEG Microsoft

Choosing the proper video container format needs to balance among several dimensions. Whether your device has enough storage space for the file, whether the device is compatible with the specific video format and whether the video quality is the top priority that you are concerned are all you have to take into account. If your device doesn't have too much space for reserving the video, MP4 is a better solution to save the video as. However, the you place the video quality in the superior position, then the AVI is definitely the best choice. It is hard to tell which video container format is better than the other. The one meeting the accurate demands of the user is the best tool.
