AVI to MKV: Convert Video from AVI(Audio Video Interleaved) to MKV(Matroska Video) with River Past Video Cleaner, AVI2MKV converter, conversion

What is AVI?

Defined by Microsoft, AVI stands for Audio Video Interleave. It is a special case of the RIFF (Resource Interchange File Format). AVI is the most common format for audio/video data on the PC.

AVI is Microsoft's response to Apple's QuickTime technology. Early AVI files were limited on choice of video and audio codecs, quality, and resolution. However, with the introduction of DirectShow, AVI became a very flexible and powerful architecture. Some newer codecs including DivX and XviD enable AVI files to have similar or even better quality than DVD.

What is MKV?

Matroska aims to become THE standard of multimedia container formats. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers.

It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is completely open source. Matroska file types are .MKV for video (and audio) and .MKA for audio-only files.

To encode MKV video, please have CCCP installed.

Add File

Click on the "Add File" button on the tool bar. The standard file open dialog appears. Select "AVI - Audio Video Interleave" in its "Files of type" combo box.

Select the file you want to convert and click "Open". The file will be added to the conversion file list.

AVI is a file container format. It may use standard Windows codecs, or any of the third party codecs. If it uses a third party audio codec, you need to have the codec installed on your system for River Past Audio Converter to decode the file.

If you get an error when adding an AVI file, please open it in Windows Media Player and see if you can play it with audio. If not, you must find out what audio compression is used in the file and download the codec.

If you cannot add the AVI file, it may contain video and audio which use codecs not installed on your system. You can verify that by playing the AVI in Windows Media Player.

If WMP cannot play the file, the codecs absent. You will need to find out which codecs are used to encode the AVI and install them.

Usually, you can install ffdShow, which is compatible with many video compression, including DivX and Xvid. For audio, you may need to install AC-3 Decoder Filter or CoreAAC.

Select output format

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Output Format" label to expand the panel. Select "MKV - Matroska Video" as the "File Type".


If you don't see the MKV output option, you have a problem with your Matroska Pack installation.

Download CCCP

Note: To convert to MKV files, you must have Matroska Pack installed.

Change Video Settings

Click on the toggle to the left of the "Video Settings" label to expand the panel.

Select "Specify" under "Size" and/or "Frame rate" to enter the video resolution and/or frame rate.

You can change the compressor, quality, size, and frame rate of the video.

Change Audio Settings

Click on the toggle to the left of the "Audio Settings" label to expand the panel.

Select the audio compressor for the conversion. Depending on the compressor, you may also change the sample rate, channel (stereo or mono), bits/sample, and bitrate.

Do not use "MPEG Layer-3" as the audio compressor. It does not work correctly in video files and often causes the conversion to abort in the middle. If you prefer to have MP3 audio in the AVI file, download lame_enc.dll instead.
