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:

Online from the browser of any device or computer.

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.

OnlineConvert.com: From this website you can convert MKV files to MP4 online, either by adding the file, attaching a link if the video is on the network or you can even select the video from Dropbox or Google Drive.

I have done a test, I have left them the email so that they can send me the converted file but I have not heard from it again and they have not sent me the file or anything.

How to Convert MKV Files to MP4 Using Commands

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.

ffmpeg -i VideoName.mkv -codec copy VideoName.mp4

In this way we will be converting the files keeping the same codec as the original file. If we wanted, we could also change the specific codec of the original video and audio by substituting the second command for this other:

ffmpeg -i video_name.mkv -vcodec VideoCodecName -acodecAudioCodeName video_name.mp4
