How to Convert AVI to MP4 on Mac OS X for Free Using Miro Video Converter How to Convert AVI to MP4 on Mac OS X for Free Using Miro Video Converter

Before starting to talk about why converting your AVI files into MP4 videos is a good choice, I probably should tell you a bit about these two media formats. AVI, short for Audio Video Interleaved, is a very popular media format that was developed by Microsoft for Windows-based systems and it is often the type of file that you will receive when downloading videos from the Internet. However, on Mac systems, AVI files are natively supported by only a few applications, such as VLC Media Player (that, honestly, can play almost all media formats) or MPlayer. On the other hand, MP4, another well-known media format, will work just fine on your Mac, as you can play it using iTunes or QuickTime (among other media players) without requiring any plug-ins or codecs.

Therefore, turning your AVI files into MP4 videos is a simple and efficient solution if you want to watch your AVI videos on your Mac using your favorite media player.

I will show you how easy it is using the freeware Miro Video Converter 3.0 by Participatory Culture Foundation (PCF). I have chosen this application because it is quite popular (among the first results after a Google search), very easy to use and free. In addition, it can also save your time by allowing you to convert multiple files in one go (batch conversion).
