Difference Between DivX and AVI

DivX and AVI are popular multimedia file formats for storing and transmitting digital video content. While they are related, they serve different purposes and have unique properties. DivX is a video codec that compresses video files, whereas AVI is a versatile multimedia container format that may hold video and audio content that has been compressed using several codecs.

Read this article to find out more about DivX and AVI and how they are different from each other.

What is DivX?

DivX is a video codec developed by DivX, LLC. It initially relied on the MPEG-4 Part 2 video compression standard, but it has evolved over time. The term "DivX" is derived from "Digital Video Express," a failed attempt to create a DVD rental system

To minimize the size of video files while maintaining good quality, DivX uses powerful compression techniques. It achieves this by analyzing the video content and deleting unnecessary data before compressing and decompressing it during playback. This compression method reduces file size dramatically, making it easier to save, share, and broadcast videos over the internet.

Following are the key features and characteristics of DivX:

  • Compression Efficiency: To accomplish efficient video compression, DivX uses a variety of compression algorithms. Interframe compression, motion correction, and quantization are examples of these. DivX may achieve high compression ratios while minimizing quality loss by using temporal and spatial redundancy in video footage.

  • Quality vs. Size Trade-off: DivX aims for a balance between video quality and file size. Although the compressed videos are smaller in size, they maintain a good level of visual fidelity. However, the amount of compression and resulting quality can be modified throughout the encoding process, allowing users to choose smaller file sizes or higher video quality depending on their needs.

  • Support for Advanced Features: To improve the watching experience, DivX provides a number of additional features. Multiple audio tracks, subtitles, chapter markers, and menus are supported, allowing users to create more interactive video content. DivX also has complex video features such as numerous encoding profiles, post-processing filters, and custom settings for fine-tuning the output.

While DivX was once widely used, other video codecs such as H.264, H.265 (HEVC), and VP9 gained popularity due to higher compression efficiency and wider industry support

What is AVI?

Microsoft developed the AVI (Audio Video Interleave) multimedia container format in the early 1990s. It was one of the first digital video container formats and gained popularity due to its simplicity and cross-platform compatibility. AVI files can store synchronized audiovisual content since they can store both audio and video data.

Following are some of the key features and characteristics of AVI:

  • Container Format: AVI is a container format, which means it acts as a container for audio and video data that has been compressed with various codecs. It does not specify the compression algorithm, but it provides a standard framework for storing and playing back audiovisual content. Because of this flexibility, AVI can accommodate a wide number of codecs

  • Video and Audio Streams: Multiple video and audio streams are possible in AVI files. This feature allows the storage of many versions of video or audio content within a single AVI file. An AVI file, for example, might contain numerous language tracks, subtitles, or alternative viewpoints of the same video.

  • Metadata: AVI allows for the insertion of metadata within the file, which provides information about the content such as title, author, creation date,and so on. Media players and software programmes can use this metadata to provide relevant information to the user.

  • Limitations: AVI, despite broad support, has some limitations. One important drawback is that it does not support current compression technologies such as H.265 (HEVC) and VP9, which provide more efficient compression. AVI files are typically larger in size than files compressed using newer codecs, potentially causing storage and bandwidth issues. In addition, AVI does not allow features available in more advanced container formats, such as menus, chapters, and interactive elements.

Difference between DivX and AVI

The following table highlights the major differences between DivX and AVI:

File Extensions




Evolved with DivX Plus and DivX HEVC versions

Continued usage, but newer formats like MP4 and MKV have gained prominence.


Usage has diminished with the rise of newer codecs.

Lacks support for modern compression standards and advanced features


In conclusion, DivX is a video codec that compresses video files, whereas AVI is a versatile multimedia container format that may hold video and audio content that has been compressed using several codecs. DivX files are usually smaller in size and of high quality, whereas the quality and size of AVI files depend on the codec used.
