When people need WebM subtitles

Web video is often published as WebM or MP4 with a separate caption file. Browsers play captions from a WebVTT file attached with a <track> element, not from SRT, so for your own web page you will usually want VTT: audio to VTT and the SRT to VTT converter cover that. SRT is the right pick for editors, most social platforms and desktop players.

Steps

  1. Upload the .webm above.
  2. Read the transcript; correct names and acronyms.
  3. Export SRT (or VTT for a web page).
  4. Attach it in your player or platform.

Recording tips for browser captures

  • Choose to share tab or system audio as well as your mic if both voices matter.
  • Do a ten-second test: play it back and confirm both sides are audible.
  • Browser recorders may skip the duration header; the subtitle times are still correct because they come from the audio.

Limits

The no-account preview covers 15 minutes and 25 MB. Screen captures with video get big fast: extract the audio with the video to audio tool if you hit the size cap.

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

Do browsers play SRT in a video tag?
Browsers' <track> element expects WebVTT. Convert SRT to VTT with the free converter if it is for a web page.
Can I use the same file on YouTube?
SRT is widely accepted by video platforms; check the platform's help page for its accepted formats.
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.
