In this post, I’d like to show how you can convert video files from AVI to MP4 on iPhone. Before getting started, let’s take a look at:

What is AVI?

AVI stands for Audio Video Interleave. It is a container format used by Microsoft’s Video for Windows multimedia framework. It is widely used by consumers and even supported by some standalone DVD players. Although still supported in Windows, and suitable for certain formats like DV, it’s not a good general purpose container, and even Microsoft uses other containers for their own video formats.

What is MP4?

MP4 is the official multimedia container for MPEG-4 video and audio. Although such video can be stored in a number of modern containers, including MPEG-2 PS/TS and Matroska, the development of MP4 is important because it gives hobbyists a replacement for the outdated AVI container which became the standard for MPEG-4 ASP (DivX, XviD, 3IVX, etc.) video.

As a matter of fact, MP4 is more widely used by popular portable devices for video playback. It is necessary to convert AVI to MP4 for more compatibility with modern devices and a wider range of other usage.
