Free MKV to AVI Converter

Free MKV to AVI Converter is a powerful, easy-to-use, and absolutely free video converter designed to help users seamlessly convert Matroska video files (MKV) to AVI or MPEG formats. MKV is a popular multimedia container that supports multiple audio tracks and subtitles within a single file, making it a preferred choice for ripping DVD and Blu-ray discs. However, due to its limited compatibility with many media players and editing software, converting MKV files to a more widely supported format like AVI or MPG becomes essential.

Key Features of Free MKV to AVI Converter:

  • Convert MKV to AVI and MPG: The primary function of Free MKV to AVI Converter is converting MKV files to AVI or MPG formats, which are more compatible with various portable and fixed media players.
  • Support for Additional Video Formats: Though primarily designed for MKV files, the program also offers limited support for converting other video formats, including AVI, MP4, WMV, FLV, MTS, OGM, and AMV.
  • Comprehensive Codec Support: Free MKV to AVI Converter supports decoding a wide range of audio and video codecs typically used in MKV files, such as MPEG-4 AVC/H.264, Xvid, VC-1, AC3, DTS, AAC, MP3, and more.
  • Flexible Video and Audio Encoders: Users can select from various video encoders, including Xvid, DivX 3, H.264, WMV, MPEG4-FFmpeg, S-MPEG 4 v. 2, Motion JPEG (MJPEG), HuffYUV, MPEG-1, and MPEG-2. Audio encoders supported by the program include LAME (MP3), MP2, AC3, AAC, WMA, and PCM 16-bit.

  • BAT File Generation: For advanced users, the software provides the ability to save FFmpeg encoder commands in a BAT file, allowing for automation and batch processing of conversion tasks.
  • Portable Software: Free MKV to AVI Converter is portable, meaning it does not require installation or system registry modifications. Users can run the program directly from portable storage devices like USB drives.

Free MKV to AVI Converter - Changelog:

  • Updated 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.
  • The ability to save the log also to an HTML file has been added.
  • Lots of minor changes and fixes to the source code and the program interface.
