How to Convert AVI to MKV

By Seth Stanton

AVI is a common container format for digital video. It has been around for a number of years and is no longer the most streamlined format for digital video. Matroska format, named after the Russian nesting dolls, is a newer and more efficient digital video storage format, resulting in smaller file sizes for video and audio of the same quality. Therefore, it may be desirable to convert from AVI to MKV to save space and make a more streamlined digital video file.

Things You'll Need

  • Super (C)

Step 1

Download and install Super (C). The download link is provided below in Resources.

Step 2

Run Super (C).

Step 3

Drag-and-drop the AVI file to be converted into the lower portion of the Super (C) window. Alternatively, you can right-click the lower portion of the window, select "Add Multimedia File(s)," and search through the Windows folder structure for the file.

Step 4

Choose "MKV" at the top-left side of the Super (C) window under "Select the Output Container." You can choose the individual video and audio codecs in the drop-down menus to the right of this menu. Common choices for video codecs include DivX, H264 and Xvid, which provide good compression and are usable across many platforms, while common audio codecs are MP3 and AC3.

Step 5

Choose additional settings such video scale size in the middle of the window. You can easily leave these choices at the default settings; however, reducing the scale size from that of your initial video will result in a smaller file size.

Step 6

Press the "Encode" button toward the bottom left of the Super (C) window to convert the AVI file to MKV. By default, Super (C) will save to the Windows desktop.
