Free MKV to AVI Converter

Older versions

Free MKV to AVI Converter is an absolutely free application which converts Matroska video files (MKV) to AVI or MPEG.

MKV is an open standard of multimedia container that allows to embed multiple audio tracks and subtitles in one file. For this reason it is very often used to rip DVD and Blu-ray discs. Unfortunately, many players and video editing programs do not support the MKV format. In this case, it is necessary to convert MKV files to more popular format, such as AVI or MPG.

The program has a number of predefined conversion settings (profiles) designed for beginners. More advanced users can customize many video and audio encoding parameters used by encoder: audio and video codec, audio and video bitrate, audio track to convert, sampling frequency, resolution, volume, deinterlacing, and other.

The basic usage of the Free MKV to AVI Converter is a very simple: to convert MKV video files, just drag & drop them into main window and click Convert button on the toolbar.

At default settings, the application converts files using Xvid video encoder and MP3 audio encoder, and automatically selects all the encoding parameters so as to preserve the original video and audio quality.
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) compared to the 32-bit version.

• The ability to convert any audio stream from a video file with multiple audio tracks.
• A number of predefined conversion profiles. Possibility to save your own settings to an INI file.
• A large number of encoding parameters: audio and video bitrate, fps, number of channels and audio sampling, the volume, change the resolution, scaling and cropping the image, deinterlacing, and others.
• Possibility of 2-pass encoding, which will increase the image quality and reduces the volume of output file.
• The ability to save the FFmpeg encoder commands in a BAT file.
• The program is portable: it does not use system registry and all settings are stored in INI files in a directory with the program. Thus, program can be run from portable devices such as pendrives, removable drives.
