How to Convert MKV Videos to MP4 in 2 Minutes Without Losing Quality

In the past I never neededconvert MKV files to MP4. If it could not reproduce an MKV it looked for alternatives and voila. But in a couple of years now the scene has changed remarkably.

The groups (ETTV) that were dedicated to uploading the majority of television series that circulate on the network announced a new editing standard.All video files should be in Matroska format (a.k.a MKV). What about AVI and MP4 then?

In the eyes of the common consumer this may seem irrelevant. However, the standard change from MP4 to MKV implies a big change. Today many devices and televisions still do not play the MKV format correctly (unless we have a good Android TV Box). Luckily, it is a new standard that is becoming increasingly popular, and many televisions with USB already recognize this format without problem.

In the next post we will take a look at The best alternatives to convert MKV files to MP4 on the main platforms:

  • Windows
  • Online from the browser of any device or computer.
  • Android
  • Mac
  • Linux

Convert MKV files to MP4 with rebox.NET without losing quality

One of the fastest programs to convert MKV files to MP4 is rebox.NET (you can download it by clicking HERE). This is the tool that EETV recommends to us. Its sole function is to swallow MKV format files and convert them into beautiful, readable MP4 at lightning speed. Convert MKV to MP4 without losing quality in no time, since the only thing this program does is change the container of the file, keeping its contents intact.

Conversion process in three steps

  • Download and install rebox.NET on your computer.
  • Run the app. The first thing you have to do is select the MKV file that you want to convert to MP4 by clicking on the “+”.

  • Once selected, you only have to click on the button "PlayWhich is right next to it to convert. As mentioned MKV to MP4 conversion is done without losing video or audio quality in any moment. If the file also contains Subtitle it will keep them anyway.
Click on «Play» to convert the file
  • Once the file is selected, the program gives you the option to choose where you want the converted video to be saved. It also offers the possibility to choose the audio quality.

As an example I can tell you that a video of about 25 minutes converts it to MP4 in a minute and a half or so. The MKV format, being nothing more than a mere container for audio / video / subtitles, does not require processing all the information in the video file data by data, so the conversion is carried out in a fairly agile way.

Another alternative to convert MKV to MP4 on Linux is to use the FFMPEG, MENCONDER or WINFF packages. We can install them from our application repository if we don't already have it, and then launch a couple of command lines.
