If you try to play a video in MKV format on TV, an Android phone, iPhone, or a third-party video player, chances are the video will not play or open. This will leave you wondering whether there’s some issue with the file. Well, it is not! It is the format that’s causing the trouble. Fortunately, transcoding files from MKV to MP4 is quite easy. Here are 4 ways to help you convert MK4 to MP4 on Windows and Mac.
But first, let’s understand the MKV and MP4 formats a little. MKV stands for Matroska, and both MKV and MP4 (MPEG-4) are container formats to store audio and video. Further, MKV is a flexible, open-standard video file format and is widely used for HD videos. However, unlike MKV, MP4 has better performance, and most importantly, is widely supported and compatible.
So if you wish to play videos on multiple devices, here’s how to convert the video format.
1. Turn MKV Into MP4 Using VLC
VLC Media Player is a free and open-source cross-platform media player software. It lets you play almost all multimedia files, including those in MKV format. Although not many know, VLC also helps convert videos into different formats. Follow the below steps to convert MKV to MP4.
Note: If you want to run the video on VLC, you don’t need to convert the file type.
Step 1: Open the VLC media player app on your computer.
Step 2: Go to Media and select Convert / Save.
Tip: You can press ‘Ctrl + R’ to quickly access ‘Convert / Save.’
Step 3: In the Open Media window, click on Add.
Step 4: Now, navigate and select the MKV file you want to convert.
Step 5: Click on ‘Convert / Save.’
Step 6: In the Convert dialog box, select ‘Video – H.264 + MP3 (MP4)’ from the drop-down menu next to Profile.
Step 7: Click on the Browse button and select the file destination.
Note: Rename the file to prevent VLC from overwriting the original MKV file if in the same destination.
Step 8: Now, click Start.
There you go. The VLC media player timeline will show the conversion progress. Once complete, it will save your video to the destination folder.
Even though the VLC media player is a readily available tool on Windows and Mac, the converted file sometimes loses audio. Hence, if you wish to take the safe route, try the next method below.
