How to auto subtitles

  1. Drop the video.
  2. Pick SRT or WebVTT and the language.
  3. Press Generate and download the subtitles.

What happens to your file

The soundtrack is transcribed on Fylane’s servers — no third party hears it — and each phrase is written with the second it starts and ends. Nothing is burned into the video; the subtitle file sits beside it.

Names, jargon and heavy accents are the usual misreads; open the file in any editor to fix a line.

Questions

How do I add the subtitles to the video?

Upload the SRT with the video on YouTube, or put it next to the MP4 with the same name — VLC and most players pick it up. Burning them in is a separate tool, coming.

What does it cost?

It runs on your credits by the minute of audio; the page shows the price for your file before you press the button.

Do this in code

      "language": "auto"
    }

The same operation, video.captions — Speech to subtitles — WebVTT or SRT with timings, from the soundtrack itself. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
