Free MP4 to AVI Converter 1.14
Free video converter that allows conversion of MP4 video files to AVI or MPG format

How to use the Free MP4 to AVI Converter - Quick Start
Free MP4 to AVI Converter is the freeware application which converts MP4, M4V and MP4V files into AVI or MPG (MPEG-1, MPEG-2).
MP4 files are commonly used in video sites (YouTube), portable players (iPod, PSP), mobile phones (iPhone) and other devices. Unfortunately, many players and video editing software does not support the MP4 format. In this case, it is necessary to convert MP4 file to more common formats such as AVI or MPG.
The program has a number of predefined settings (profiles) specially designed for novice users. While more advanced users can customize video and audio encoding parameters used by encoder: audio and video codec, audio and video bitrate, fps, sampling frequency, resolution, volume and other.
The application interface is a very simple and user-friendly. To convert video files, just drag & drop them into main window and click Convert button on the toolbar.
Most portable and fixed players should have no problems playing AVI files created with these settings.
The program is available in both 32 bit and 64 bit version. The conversion process of the 64-bit version is faster by a few to 25% (depending on the selected video encoder).
