MKV – Matroska

Format introduction

The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows.

Technical details

Matroska is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is entirely open in specification, with implementations consisting mostly of open source software.

To convert video, follow these steps:

  • Use the “Add video files” button to upload the document to the server. The size of the video file is 1Gb, but the larger the file, the more time it will take to convert. Just be patient and everything will turn out. You can convert files from AVI, WMV, MPEG, MOV, FLV, MP4, 3GP, VOB and other video formats.
  • By default, the conversion starts automatically, but you can turn off automatic conversion, in this case you will need to click the button “Convert” to convert your documents. If the conversion is successful, the file will be available in the above drag&drop area. If you just need to download a file, click on the file name. If you want to get other ways to save, then click on the “Info” to generate a QR code to upload the result to your mobile phone or tablet, and also if you want to save the file in one of the online storage services such as Google Drive or Dropbox.
