The MKV or Matroska file format is a video file format you will occasionally encounter. The advantages of this format include supporting multiple subtitle and audio tracks for videos.
The downside of the MKV format is that a lot of devices don’t support it. If you have some MKV files, you might wonder how you can get them to play on a Smart TV or another device
The VLC media player can recognize and play almost any video format, including MKV. Better yet, it can also convert them to something more universal, like MP4. Here’s how.
Step 1: Head over to VideoLAN’s website and download VLC. Make sure to read the fine print when installing, so you aren’t introducing your computer to any bloatware.
Step 2: Open the software and click the Media tab in the upper-left corner and select Convert/Save from the resulting drop-down menu.
Step 3: Click the Add button and locate the file you wish to convert on your PC. Once it’s selected, press the Convert/Save button at the bottom of the window.
Step 4: Specify your desired video format — in this case, we’d recommend H.264 + Mp3 (MP4) — using the drop-down menu beside Profile. Clicking the tool icon (next to the drop-down menu) will also allow you to further fine-tune your settings.
Step 5: Specify under Destination where you would like VLC to export your file. Then, click Start. The timeline will turn into a progress bar and once it finishes, your video will be ready. Remember that the old MKV file still exists. If you no longer want the old file and would prefer more storage space on your computer, you should delete all your old MKV files when finished.
