Note: There is a Difference between Zero and Alphabet “O.

Now let me explain the codes above for you;

  • input.mp4 – This is the Video file you want to encode the subtitle in.
  • subtitle.srt – It is the subtitle file you want to use in the video.
  • output.mp4 – This is the directory path and filename you want it to carry after the encoding.
  • language=eng – This is where you change the subtitle language (Leave it in English).

Now let us get on how to edit each path you want.

Clear the input.mp4 and then click on the Plus Icon above, Now select File Path (Browse by Yourself), From there go to the directory the video is in and then click select the video. Now You will see something like /storage/emualted……….videofile.mp4.

To put the subtitle file, Clear the subtitle.srt and then click on the Plus Icon above, Now select File Path (Browse by Yourself), From there go to the directory, find and select the subtitle just like you find for the video.

To Select Directory Path and Filename for saving, Select and clear the output.mp4 and then click on the Plus Icon, Now select Directory Path, Select any Directory (I prefer Download Directory).  You will see a request Showing Do you also want to concat a file name? (Select Yes as I always do), Enter the Video Name as you like with .mp4  ending it and press OK. On Your Screen, You will see it as in the below screenshot.

I Hope everything explained is clear, if not comment below with the problem you are encountering let’s help you solve it.


  1. I use a cloud storage named ‘terabox’.When I download a torrent file,which has subtitles already in it and I upload it on terabox, Terabox plays that subtitles,which is switchable, I want to merge subtitles in that way,not like ffmpegcli

    1. You can only achieve that using Online video editors or offline video editors. Terabox don’t merge subtitles, they serve it differently as it is in your MX Player, VLC otherwise the subtitles is been hardcoded inside the video

  2. I’ve just tried all that you said (everything but the “” with the path) and it worked. Thank you.

    I have a question: is it possible to hardcode another format of subtitles? The default output is a plain white captions, I want to set a black border and a yellow captions. Thanks a lot!

  3. Me again. I’ve checked the result file, and the art has been integrated to the video, so is able to be selected or not. But, how is it possible to HARDCODE the subtitles to the video? I mean, burned to the video, always visible.

    I really appreciate your work and answer. 🙂
