MP4 to text — transcribe a video file without uploading it

An MP4 carries its sound in an AAC track; this page reads that track straight from the file on your device and writes it out as text — with the video playing alongside so you can follow along.

      What is inside a subtitle file

      Every cue the transcriber writes has three parts. Click a cue in the Subtitles view to hear it.

      SRT is what video editors and YouTube take; VTT is what web players read. Both come from the same cues.

      How it works

      1. Drop an audio or video file into the box above, or choose one from your device.
      2. The speech model loads in your browser and the text appears as it is transcribed. The file is never uploaded.
      3. Copy the transcript, or download it as TXT or as SRT subtitles.

      FAQ

      Do I need to extract the audio first?
      No. Drop the MP4 as it is; the sound track is read directly. Only for videos longer than about 35 minutes is it worth exporting the audio as MP3, which has no length limit.
      Can I get subtitles for the video?
      Yes. Download SRT for editors and YouTube, or VTT for web players. Both are timed from the same lines you see on screen.
