Have you ever wondered how to convert MKV to MP4 in just 10 seconds? Well, we have all the answers about the MKV files, their features, and why you should convert this type of file to MP4. Just read the lines below, and you will have them too. First, let’s start with the basics.

MKV file format – the basics

The first thing you should know about the MKV file format is that it is a multimedia container format. It can contain audio, video, and subtitles in a single file regardless of the encoding type. Meaning, you can have an MKV file that contains AAC audio and H.264 video.

This type of file format has several features that won’t allow the MKV file format to become outdated. One of the first ones worth mentioning is the option of fast seeking. Another is the existence of chapters, menu, and metadata support. Plus, there is an option for different selectable audio and video streams. Besides, MKV files have online streaming compatibility.

If you want subtitles in your MKV file, it’s not a problem at all. This type of file has hard-coded and soft-coded subtitle support. And if you want to allow playback of corrupted files, that’s an option too.

MKV files are also highly adaptive and easy to use. However, due to a lack of compatibility with different programs, you sometimes have to convert MKV to MP4.

How to open MKV files

Because MKV files are not a standard, there can be a problem or two when it comes to them. Yes, MKV support is growing rapidly, but still, you’ll have to use a compatible media player or download the appropriate codec.

One of the most popular media players you can open MKV files is VLC. It has built-in support that doesn’t require any additional downloads.

Windows Media Player, on the other hand, sometimes requires additional codecs download to help you with the MKV file. And it is by far easier to convert files to MP4 instead.

If you are a Mac user, you should either convert MKV to MP4 or download third-party software to open your files. And if you are an iPhone user, VLC, MCPlayer, PlayerXtreme, and KMPlayer will do the job.

MKV vs MP4

MKV files are often converted to MP4 file format due to their lack of compatibility. However, this is not the only difference between these formats.

MKV files are usually greater in size than MP4 files, but when it comes to file quality they are almost the same. Quality has many different influencing factors, including resolution, frame rate, sample rate, bitrate, etc. That is why it’s so hard to make correlations based on a single or even just a few factors.

Also, MKV files can combine audio, video, and streams, while MP4 can contain even images. For example, the MP4 file format sometimes stores photos of movie intros. On the other hand, the MKV file format supports FLAC lossless audios while MP4 not. Instead, MP4 supports another lossless audio file format known as ALAC.

Also, MKV supports selectable subtitles of ASS/SSA while MP4 not. The same goes for the selectable audio tracks.
