How to convert MKV to AVI?


MKV is an extension of the Matroska container format used for storing all sorts of audio and video tracks. The last letter of the file extension stands for Video. MKV is often used to back up movies, as it is capable of storing high definition video (HD video) and an unlimited number of audio /subtitle tracks.

However, you may want to convert MKV to AVI in various situations. AVI is supported by a bigger number of hardware and software players, so it is preferable if your video must be playable. You may also want to reduce file size while keeping reasonable quality.

We will see how MKV can be converted to AVI using Movavi Video Converter.

Step 1: Download and install the program.

Download Movavi Video Converter to your computer and start the file. Follow on-screen instructions to install the video converter.

Step 2: Start the program. Select MKV to convert to AVI.

Start the video converter. The main window of the program will be shown:

Add MKV files to convert

Click the "File" button on the toolbar. A usual "Open" dialog will pop up:

Open MKV video

Browse to the folder where you keep your MKV files, highlight the file in question and click "Open". You can also add several files at once.

Step 3: Set output format and folder. Convert MKV to AVI.

Your MKV video will appear in the conversion list:

Convert MKV to AVI

You can preview the video, using the preview area on the right.

In the lower part of the window, click the arrow in the "Preset" field. A list similar to the following one will be shown:

Choose the AVI video preset

Select "AVI Video (*.avi)" from the list.

Under the "Preset" field, find the "Destination" field and choose a folder for saving converted AVI files. We selected saving AVI into the same folder where our MKV was.

There is an easy way to control quality / size of the output file. Just click the link in the "Quality/Size" column (2). The following control will pop up:

Adjust AVI quality

You can simply drag the slider to the left or to the right to make the output file smaller or bigger (higher quality).

Finally, click the big "Convert" button in the right lower corner of the program (3). The MKV converter will start processing your video.

The free trial version of Movavi Video Converter adds a logo to all converted videos (the source files remain unchanged). If you like the program, you can remove this limitation by registering Movavi Video Converter.
