Description

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 (iPodPSP), 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 button on the toolbar.

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).

3rd party software

To encode the video files the program uses the FFmpeg encoder (ffmpeg.org).

To retrieve information about video files, the program uses the library MediaInfo.dll (http://mediainfo.sourceforge.net/).

The program is accompanied by a special version of the FFmpeg encoder, adapted to the needs of the program. Not recommended to use other versions of FFmpeg.

Changelog

Version 1.17 (2021.01.22)

  • New conversion engine (FFmpeg) and multimedia information library (MediaInfo).
  • Information about the conversion progress is displayed on the title bar of the main window and on the taskbar.
  • Fixed Stack overflow bug when selecting next files in the list very quickly.
  • Added support for files from network shares whose names start with the characters \\.
  • When saving the report to a text file in the File properties window, UTF-8 encoding is used (in previous versions the system default code page was used).
  • After the user has interrupted the conversion, the program displays a window asking whether to delete the incompletely converted file. Such files usually have a damaged internal structure and cannot be played.
  • If incorrect parameters are passed to the conversion engine (FFmpeg) and the conversion process fails, the output file will be automatically deleted. Such a file usually does not contain any data (0 bytes in size) and only unnecessarily litter the disk.
  • The file names, encoder options and some words (error, invalid, unable etc.) are highlighted in the error log window. This makes the log more readable now.
  • UTF-8 encoding (instead of the system code page) is used when writing the error log to a text file.
