Closed captions are a separate file the viewer turns on with the CC button. Upload a video or paste a link, and download that file as SRT or VTT, ready for the platform your video lives on.
How it works
Any video or audio file, or a public link from YouTube, Google Drive, TikTok and other sources.
Read it against the audio where it matters: names, numbers, terms. Corrections carry into the caption file.
Download .srt or .vtt and upload it wherever the video is hosted. The viewer gets a CC button.
Closed versus open
Closed captions travel as a separate track or file. The viewer can switch them on or off, choose a language, and a screen reader or search engine can read them. This page makes that file.
Open captions are drawn into the picture and cannot be switched off. They suit social clips that autoplay muted. They are made in a video editor, which imports the caption file from here: see add subtitles to a video.
Broadcast television uses its own closed caption standards (CEA-608 and 708, delivered as SCC or embedded data). Those are a different deliverable; the SRT from here is a common starting point that captioning software converts. For broadcast workflows see broadcast captioning.
Where the caption file goes
A note for accessibility work: guidelines ask that captions be accurate, synchronised, complete and include meaningful non-speech sounds. The file made here covers speech. Add sound notes such as [applause] or [music] by hand where they matter, and review the text. The requirements are laid out in WCAG caption requirements and captions for ADA compliance.

Real output, unedited: a public-domain LibriVox reading of the Gettysburg Address (2 min 41 s) transcribed here in October 2026. The repeated word and the missing capitals are what came back; you would fix those on the transcript before downloading.
Before you rely on it
Each cue is a phrase from the transcript with its start and end time. Most run a few seconds. A passage spoken without a pause can come out as one long cue of up to about half a minute, so split those in your editor if your platform wants two short lines at a time.
Cue times are taken from the recording itself, so the file lines up with the video or audio you uploaded. If you trim the start of the video afterwards, shift the cues by the same amount in your editor.
On public test recordings, about 7 words in 100 differed from the reference for clean English read speech, between 4 and 9 in 100 for Spanish, Portuguese, Russian, French and German, and about 21 in 100 for Hindi. Noisy rooms, music and crosstalk do worse. Method and every number: the benchmark.
Open the transcript, correct a misheard name or number on its line, and the SRT and VTT you download carry the correction with the timing unchanged.
You get the subtitle file. Fonts, colours, position and captions drawn into the picture are done in your video editor or player, which reads this file.
