MKV Format: What is and How to Play It

In the vast landscape of digital media, various file formats are used to store and transmit audio and video content. One such format that has gained popularity over the years is MKV. MKV, short for Matroska Video, is a versatile and open-standard multimedia container format. In this article, we will explore what MKV is, how to play MKV files, methods to convert MKV, compare MKV with MP4, and address frequently asked questions about this format.

MKV Format

1. Part 1. What is MKV Format?

MKV is a multimedia container format that can hold an unlimited number of video, audio, image, or subtitle tracks in a single file. It is an open standard and free container format that was developed by the Matroska project. Unlike other formats like MP4 or AVI, MKV is not limited by proprietary specifications, making it an ideal choice for users who value flexibility and compatibility.

The MKV format is known for its ability to support a wide range of codecs, allowing users to choose the best compression method for their content without being restricted to a specific codec. This flexibility makes MKV a popular choice for high-definition videos, including those with multiple audio tracks and subtitles.

2. Part 2. How to Play MKV File

Playing MKV files is relatively easy, thanks to the widespread support for this format across various media players. Popular MKV players like VLC, MPC-HC, and Kodi natively support MKV files. Simply open the player and load the MKV file to start playback. Additionally, many modern smart TVs, streaming devices, and gaming consoles also have built-in support for MKV, making it a convenient choice for home entertainment.

By default, Windows Media Player (WMP) doesn’t natively support MKV (Matroska) files. However, you can make Windows Media Player play MKV files by installing the appropriate codecs.

Method 1: Install Codecs

You can install codec packs that include the necessary components to play MKV files in Windows Media Player. One popular codec pack is the K-Lite Codec Pack. Here’s how you can use it:

Step 1. Download K-Lite Codec Pack:

Visit the official website:

Download the Standard or Full variant (the Standard variant usually suffices).

Step 2. Install K-Lite Codec Pack:

Run the downloaded installer and follow the on-screen instructions.

During installation, you can choose the components you want to install. For playing MKV files, you generally don’t need to change the default settings.

Step 3. Play MKV files in Windows Media Player:

After installing the codec pack, try playing your MKV file using Windows Media Player.

3. Part 3. How to Convert MKV

While MKV is a versatile format, there may be instances where you need to convert it to a different format for compatibility reasons or to reduce file size. Numerous video converter tools are available that can convert MKV files to formats like MP4, AVI, or others. Popular and free MKV to MP4 converters like HandBrake and Freemake Video Converter provide easy-to-use interfaces for this purpose.

Here’s a general guide using a popular tool called HandBrake. HandBrake is a free, open-source video transcoder that works on Windows, macOS, and Linux.

Step 4. Make Video and Audio Settings:

Step 5. Set Destination:

Step 6. Start Conversion:

Click the “Start Encode” button to begin the conversion process. The time it takes will depend on the size and complexity of the original file.

Step 7. Wait for Completion:

4. Part 4. MKV vs MP4

MKV and MP4 are both popular multimedia container formats, but they have some differences. MKV is an open standard, while MP4 is a proprietary format developed by MPEG. MKV supports a wider range of codecs and features, making it more flexible for users who require diverse multimedia options. On the other hand, MP4 is widely supported across devices and platforms, making it a more universally compatible format.

When deciding between MKV and MP4, consider your specific needs. If flexibility and a broad range of codec support are crucial, MKV may be the better choice. If universal compatibility and widespread playback support are more important, MP4 might be the preferred format.

Certainly, here’s a comparison between MKV and MP4 in a tabular format:
