Convert MKV to MP4 using VLC Player


Do you have a video file that is in MKV format that you want to watch on a smart TV? Maybe using a USB memory stick? Well, you may struggle as most TV’s will not understand what format an MKV video file is.

However, there is a very quick method of converting your MKV to MP4 video format – a format that is pretty standard and almost all media devices, including TV’s, will understand allowing you to watch.


There are a few things that you will need to ensure that you have before starting this process:

  • The latest version of VLC Player installed
  • Enough disk space to store the created MP4 file output
  • Correct codecs for your MKV to MP4 conversion

Disk Space

Once you have carried out the MKV to MP4 conversion the MP4 file will approximately the same size as the original MKV file. So ensure that you have this amount of disk space available or else you will run out and the conversion will fail.


Windows 10 users will most probably have all the required video codecs to actually run any conversion. However, if you are in doubt, or if you are running an older operating system like Windows 7 or maybe even as far back as Windows XP (some do) then you should go ahead and download and install the K-Lite Codec Pack which has been around for years and works a treat.
