    Synchronized online video in multiple languages ​​can be displayed in one file. The biggest advantage of MKV is its support for AVC / H.264, followed by AVI. This codec is used for HD playback.

    Attention! Some of the information on the page is over 5 years old. I am saving it for reference, but it does not reflect my current knowledge and beliefs.

    Do you have a video in MKV format and you cannot open it because some educational programs (for example, Sony Vegas Pro) do not support this format? If so, you will probably be surprised at how you convert it to another format. I just found a way to do it right now.

    To understand this method, the first thing you need to know is that media sorting is just containers (like MKV, probably Matroska). Each format encapsulates multiple streams, usually video and music streams. Now each stream is encoded with a specific codec. Different codecs can be used, but for the file I needed to convert, Media Player Classic (my favorite video player installed with the K-Lite Codec Pack) after selecting File> Properties shows the following information: p>

    Type: Matroska
    Video: Vi o MPEG4 (H264) 720×400 25 frames per second [V: English [eng] (h264 main L4.0, yuv420p, 720×400) [Standard]]
    Audio: HiFi AAC 44100 Hz [A: aac lc, 44 100Hz Stereo [Standard]]

    MPEG4 video is the same codec that is sometimes used with the MP4 file format! This could mean that we are converting (“repackaging”) a file that is returned to a different container format, overwriting the sources as they are, without actually converting any video or audio files – which should be very fast (convert only a good long continuous film) takes a few seconds). and will not even result in a loss of quality.

    For this, I used the VLC media player. This app has native codecs for many video and audio formats, so you don’t need to rely on codecs installed via Windows. The player is actually a kind of powerful overlay for the library, which can often do all sorts of things, like moving videos around the network (probably hence the company name. “VideoLAN”) or modifying files.

    1. Start “VLC Media Player”.
    2. Through a special main m Media> Convert / Save …
    3. Click the Add … button while collapsing to File.
    4. Select MKV file. After that, you need to add it to our list. (You can also drag the insider to the list.)
    5. Click the Convert / Save button.
    6. Select a profile: Video – H.264 + MP3 (MP4).
    7. Click the button with the new symbol marked: “Change current profile”.
    8. In the “Encapsulation” tab, leave “MP4 / MOV” selected.
    9. On the Video Codec tab, select Video and Save Original Video Track.
    10. On the Audio, Codec tab, select Audio and Keep Source Audio Clips.
    11. Click the Save button.
    12. Under Destination, click the Browse button to select the directory and company name for the target MP4 file.
    13. Click the Start button.
    14. Watch the progress bar in the main window even if the file is being converted.
    15. After that my VLC (version 2.2.1) seems to be stuck in an infinite loop, so I have to terminate it using the System Task Manager, but it doesn’t matter – the target file is obligatorywill be created.

    Important update from 03/22/2020: I found another one to quickly convert MKV to MP4 for using OBS Studio. It is a free and therefore open source application that is primarily intended for recording and streaming over the Internet. The function we need is in the File> Remux Recordings menu.

    If MKV info and facts do not output sound when using Windows PC, Mac or TV, it is practically because MKV files use DTS sound quality, which is incompatible with some video games or TV applications.

    DTS (Digital Theater Systems) is one of the most well-known CD codecs in professional and home theater systems for recording and reproducing high-resolution multichannel audio. MKV, a media container style that can combine audio, video and therefore subtitles into onefile often used for movies and contains DTS sound.


    mkv files with DTS audio will not work on some HDTVs such as LG and Samsung Smart TVs. Also, for many multimedia game enthusiasts like Windows Media Player, QuickTime and guitarists, VLC does not play DTS audio or MKV video with DTS surround sound.
