MKV Subtitles

How to add subtitles to an MKV file

MKV stands for Matroska Multimedia Container. As the name implies, it’s a video container that can also include several inner layers (exactly like a Russian doll Matryoshka): audio tracks and/or subtitles.

To embed subtitles in MKV, directors and professional editors use special costly software. But we have a better solution for you.

Our tool adds subtitles to a video permanently. It allows adding an SRT to MKV, inputting the captions manually, and functions as a file converter. The recommended formats for social media are MP4 and MOV, and – such a lucky coincidence – our tool supports them and many others.

How to burn subtitles into MKV

1. Upload your file

   You can either select recordings from your personal device, or use videos, stored in your cloud storage.

   

   For the first option, hit the blue button “Choose file”. For the second, call a drop-down menu on the right of the pane. Select a clip saved to Google Drive or Dropbox.

2. Merge SRT with MKV or create subtitles

   As soon as the video is uploaded, you can upload a ready .SRT file or add captions manually. In the first case, the tool will merge subtitles with MKV automatically.

   Whatever you choose, you’ll be transferred to the editor where you can add, delete, alter and set subtitles as you wish.

   

   Write captions in the box to the right of the player and set the timing to synchronize subtitles with the video. You can drag the ready entries along the timeline below to change their start/end time and order.

   

   Hit the “Styles” tab and select the font, size, colour, alignment and other settings of the text.

   

   Don’t forget to choose an output format – if you are going to share your clip on your Facebook or YouTube account, just convert MKV to MP4, with the subtitles embedded earlier.

   

   When you are happy with the result, click “Create”.

   Please note that the tool adds hard subtitles only. Hard subtitles are burned in, or hard coded, as an overlay over your video and cannot be turned off or on later in a player.

3. Save the result
