MKV (which stands for Matroska) is a universal format used for storing multimedia content like movies, concert videos, and TV shows in HD. Although this format is getting more and more popular, it’s only supported by a limited number of devices.
Let’s have a look at solutions to other common problems related to MKV files.
Can’t open a video file?
Either your device doesn’t support the file’s format, or you need to install a special media player. In both cases, converting the file to a suitable format is the best solution.
Is your video distorted?
There can be a number of possible explanations. Most likely, however, the video file is just too large. Reducing its size in a conversion app might help.
Usually, this is due to an incorrect audio codec used in the file. Change the codec using the right kind of software – like a dedicated video converter.

MP4 vs. MKV Comparison
Let’s have a closer look at the differences between MP4 and MKV formats.
MP4 (MPEG-4 Part 14) is a container format used for storing video and audio streams. Low loss of quality combined with high compression levels, as well as its compatibility with almost all default media players, makes the MP4 format one of the most widely used formats on the Internet. You can play MP4 files with any default media player.
MKV (Matroska Multimedia Container) is a free, open-standard video container format. MKV files can contain an unlimited number of video, audio, and subtitle tracks in one file. That’s why this format is widely used for storing multimedia content such as movies and TV shows. Using this format, you can watch your favorite movies with any combination of audio tracks and subtitles. It’s less universal than MP4 because you need to install a special media player to open MKV files, and you can’t open these files on iPhones.
|Video-encoding formats||H.264, H.265, MPEG-2, MPEG-4, H.263, VC-1, Dirac, others||H.264, H.265, MPEG-4, MJPEG, Theora, VP9, DV, others|
|Audio-encoding formats||AAC, MP3, AC-3, Apple Lossless, ALS, SLS, others||AAC, AC3, MP3, ALAC, Vorbis|
|Device and OS compatibility||Compatible with almost all devices and operating systems||Some TVs, media players, and mobile devices. Windows PC (with a special codec installed), no native support in macOS|
To sum up, if you want to watch a movie with the audio track in your target language and English subtitles on a Windows PC, MKV is your best choice. In most other cases, MP4 is much more convenient.
Frequently Asked Questions
What Is the MKV Format Used For?
MKV (which stands for Matroska Video) is a universal format designed as a new standard for high-quality video compression. MKV can combine HD video with multiple audio tracks and subtitle tracks – that’s why it is a good choice for storing movies, TV shows, and concerts.
Can I Play MKV Files on a Mac?
Unfortunately, Mac users may encounter difficulties when attempting to open MKV videos, and iPhones do not support MKV at all. To open MKV files on Apple hardware, you need to convert MKV to a more common format, for example, MP4. The best way to do this is to use a dedicated conversion program. Movavi Video Converter can help you transform your files fast, thanks to its SuperSpeed mode.
Can MP4 Files Be Played on a Mac?
Although Mac’s default player supports the MP4 video format natively, it can only play files compressed with MPEG-4, MPEG-2, and H.264 codecs. If you want to play an MP4 file encoded with a different codec, you’ll need to install a player that supports that codec, or convert the video clip to another format, like MOV.
Is MKV Better Than MP4?
Both MKV and MP4 are popular video formats that support H.264 video. However, Apple smartphones and Mac computers don’t support MKV natively, while MP4 is a default format for iPhone, iPad, and many other devices. So, if you want to transfer videos to your iPhone, it’s better to choose MP4, but if your device supports MKV, you can keep your files in this format.
Will Converting MKV to MP4 Reduce the File Size?
Yes, it will help to make the file smaller. MKV files are usually larger than MP4s because of some attributes like multiple tracks and subtitles. A smaller file size means quicker downloads as well as savings in storage space. So if you need your MKV video to be smaller, try converting it to the MP4 file format. If you’re worried about quality loss, use Movavi Video Converter – it enables you to change the format of your videos while retaining good quality.
