The Origins: A Historical Look at AVI and MP4
The AVI (Audio Video Interleave) format was developed by Microsoft in 1992 as part of its Video for Windows technology. It was designed to be a universal standard for storing digital video and audio streams in an interleaved manner.
The MP4 format emerged later on in 2001. It was standardized by the Motion Pictures Expert Group (MPEG) as their fourth major video compression format, hence the name. Specifically, MP4 files use the MPEG-4 Part 14 or MP4/M4A specifications.
So while AVI has its roots in the early 1990s during the rise of multimedia PCs, MP4 is a newer format that came about in the age of digital video, when efficient compression was becoming critical for storage and streaming.
Under the Hood: How AVI and MP4 Store Video Content
On a technical level, AVI and MP4 take different approaches when packaging digital video content…
AVI Format
AVI files are based on the Resource Interchange File Format (RIFF). At its core, RIFF provides an extensible binary formatting framework for embedding different types of data like video, audio, metadata, etc.
Within an AVI file, video and audio data streams are interleaved or combined sequentially into one single file structure. This interlacing allows simultaneous playback of the video and audio components.
A key aspect of AVI is its use of codecs to compress the video during encoding…
MP4 Format
Unlike AVI, MP4 uses the MPEG-4 Part 14 specifications for packaging multimedia content. This defines MP4 as a multimedia container format, meaning it can contain embedded video, audio, subtitles, images and other types of data within one file.
MP4 incorporates digital rights management features as well. This allows content creators to apply access controls if they want to restrict usage or distribution of MP4 files.
For video compression, MP4 files typically rely on advanced codecs like H.264/MPEG-4 AVC and H.265/MPEG-H HEVC which provide much better compression efficiency versus older codecs.
Video & Audio Quality Comparison
When it comes to perceptual quality, both AVI and MP4 are capable formats. The difference lies in how they handle compression and balance out considerations for quality and file size…
AVI Quality Considerations
Being an older format, AVI uses simpler compression algorithms that can preserve excellent video quality with lossless compression techniques. This comes at the cost of larger file sizes however.
For audio, uncompressed quality is retained but again takes up more storage space. Some codecs provide lossless audio compression to mitigate this issue.
MP4 Quality Considerations
MP4 leverages modern video codecs like H.264 to manage an optimal balance between compression efficiency and visual quality. This means smaller files sizes with excellent, albeit not completely lossless, video quality.
Similarly for audio, advanced yet lossy compression techniques shrink down file size substantially while maintaining reasonably high quality.
File Size & Storage Requirements
Due to its minimal compression, AVI video files tend to be much larger compared to more efficient MP4 video files.
To demonstrate this difference…
Compatibility With Devices & Software
When it comes to compatibility across devices, web browsers and media players, MP4 tends to have wider support being the newer gold standard. However, AVI enjoys great backwards compatibility with older systems.

Editing Considerations
Both formats can be imported into major video editing tools like Adobe Premiere Pro and Final Cut Pro. However, working with the highly compressed MP4 format can slow down editing workflow.
Use Cases
Based on their technical characteristics and performance across key areas, AVI and MP4 tend to suit different use cases better.

Converting Between the Formats
While choosing the right format upfront is ideal, you may sometimes need to convert videos from AVI to MP4 or vice versa. Fortunately, modern encoding tools make these conversions straightforward.

The Verdict: AVI vs MP4 – Which is Better Overall?
When all factors are considered, MP4 has emerged as the defacto standard for digital video distribution and streaming today for good reason. Here‘s a recap of the key pros and cons:
| Format | Pros | Cons |
|---|---|---|
| AVI | – Excellent lossless quality | – Large file sizes |
| MP4 | – High quality despite compression | – Lossy compression |
While both formats have their merits, MP4 strikes the perfect balance between quality and compression for convenient digital video.
