MKV to SRT

MKV to SRT

Generate an SRT from an MKV file. Upload the OBS recording or video, review the transcript and export an .srt. Useful when a video has no subtitles, or you want your own for a recording you made.

MKV already has a subtitle slot

Matroska can carry subtitle tracks inside the file, and many players pick up an .srt sitting next to the video with the same name, for example talk.mkv and talk.srt. If you would rather embed it, MKVToolNix's free tools can mux the SRT into the MKV as a track; we do not do that step, we make the SRT.

Steps

  1. Upload the .mkv above.
  2. Correct the transcript while listening.
  3. Export SRT and give it the same base name as the video.
  4. Place both files in the same folder, or mux with a tool of your choice.

Why this beats extracting existing subtitles

If the MKV has subtitle tracks already, extract those rather than transcribing again. If it does not (screen recordings, lectures, your own footage), speech recognition is how you get timed text. If you only want a script rather than timed cues, the SRT to text cleaner strips the numbers and times.

Multiple audio tracks

OBS may store mic and desktop sound as separate tracks. If the transcript is missing a voice, check which track the file lists as its default audio and mix them in OBS before the next recording.

How it works

  1. Add a recording

    Drop in a video or audio file, choose one from your device, or record from the microphone. Nothing to install.

  2. It transcribes

    Speech becomes timestamped text, with speaker labels when more than one person talks.

  3. Read, fix, export

    Click any line to correct it, then download TXT, subtitles, Markdown, JSON or CSV.

Questions

Can you add the subtitles into the MKV?
No. We produce the .srt; tools like MKVToolNix can embed it.
Does it use the MKV's existing subtitles?
No. It transcribes the speech.
Does the SRT have one line per sentence?
Each transcript segment becomes one subtitle cue with its start and end time, as the recogniser produced it. Some cues can be longer than a screen likes; the free subtitle line splitter re-wraps them in your browser.
Is it free?
Yes — one file up to 15 minutes and 25 MB with no account, up to 3 tries a day. A free account keeps your transcripts in a library and lifts the guest limits; the current limits and paid plans are on the pricing page.
