MP4 vs. AVI: Comparison

If you’re wondering: “Is AVI better than MP4” or “What is the difference between AVI and MP4?”, have a look at the detailed comparison below.

What is AVI?

AVI stands for Audio Video Interleave, a multimedia container developed by Microsoft in 1992. This format enjoys full compatibility with Windows-based players and other programs with related codecs. AVI files carry both audio and video data, saved with the .avi extension.

Pros

Cons

  • High-quality audio fidelity

  • Can be used to make playable DVDs

  • Does not need special hardware or software to run

  • Supported by many codecs to achieve the desired AVI audio output format

  • Suitable for promos, short movies, and ads because of its familiar format and compression capabilities

  • Best for master files since it's good at maintaining its quality over time

  • Can be quite large compared to other file formats if uncompressed, forcing you to trade disk space with quality

  • Compression beyond certain limits may lead to a decline in quality

  • Does not support user interactivity

  • Doesn't natively support incorporating soft subs

What is MP4?

Short for MPEG-4 Part 14, this multimedia container was developed by the Moving Picture Experts Group (MPEG). Most MP4 files save with .mp4 extension though some come with .m4a or m4p file extensions.

Pros

Cons

  • Works across multiple platforms, thus, easier to distribute and use

  • Can contain metadata and Extensible Meta Data Platform, including subtitles

  • Can integrate with 3D graphics and menus, and other user-navigation options

  • More versatile compared to AVI

  • Possible for a high degree of compression to produce smaller sizes suitable for streaming audio-video files on online platforms

  • Supported by many open-source media players, such as VLC, which provides complete support for MP4; it even works on Linux operating systems

  • Codec compatibility issues may result in audio drifting out of sync with video

  • Editing requires lots of computing power since both audio and video in this format are in a single file

  • Lossy format – a higher degree of compression may cause a flop in the audio and video quality of the output

  • Prone to illegal distribution of copyrighted content due to its popularity and portability

Quality

Let’s have a look at the AVI vs. MP4 quality. Both AVI and MP4 are video wrapper formats, but AVI uses the DivX codec while MP4 works with the MPEG-4 AVC/H.264 codec. This implies that AVI has better quality compared to its MP4 counterpart. However, the quality difference between MP4 and AVI may not be quite apparent to the naked eye since both are available in HD.

Compression

Since it uses less compression to store video and audio files, AVI files occupy much more space compared to MP4 files. You can create MP4 without compression as well, but it generally takes less space compared to AVI. MP4 also uses the AAC compression algorithm for its audio, while H.264 or MPEG-4 technique applies to its video output.

File size

When it comes to file sizes, AVI files are considerably larger than MP4. But you can compress AVI files to make them smaller or convert them to other formats such as FLV or even MP4. MP4, on the other hand, is a lossy video container occupying less space than its AVI counterpart.

Summary

So, should you choose MP4 or AVI? Well, the MP4 vs. AVI debate doesn't provide a clear winner. Both formats have their strengths and weaknesses, and they could be a deal-breaker. While AVI seems to be the better media container for quality, it uses very large file sizes; hence, may require compression to smaller file formats. MP4, on the other hand, uses smaller file sizes and works with almost all media players but has an inferior video output quality compared to AVI. However, use the AVI file format for TV production and a bit of YouTube and MP4 for everything else.
