Drop an MP4 or MOV and download an SRT file with every line timed to the speech, ready for YouTube, Vimeo, LinkedIn or your editing software. The video opens on your own device and is never uploaded, and the subtitle files are free for any video up to ten minutes.
Live preview, rendered on this page by the same engine that burns your video.
MP4, MOV or M4V, from a phone, a camera or a screen recorder. The page reads the sound out of the file on your device, and the picture never goes anywhere. Up to ten minutes and 1.2 GB on a computer, 250 MB on a phone.
Every word is timed as it is heard and opens as a script under the video. Click a word to correct it: one click fixes the same word everywhere it was heard, and this browser remembers the names you fixed.
Choose how many words each caption holds, one to six words at a time, then click SRT. VTT, ASS and plain text are one click away, and so is the same video with the captions burned in.
An SRT file is plain text: a number for each caption, its start and end time to the thousandth of a second (00:00:04,120 --> 00:00:05,360), then the words. Burncaps starts a new caption at the end of a sentence, after a pause of about a second, or when it reaches the number of words you chose, so each line follows the way you speak instead of cutting a thought in half.
| Where it is going | Download | Why |
|---|---|---|
| YouTube | SRT | Added as a subtitle track in YouTube Studio, so viewers can switch it on or off |
| Vimeo or LinkedIn | SRT | Both take an SRT file as the captions for an uploaded video |
| Premiere Pro, DaVinci Resolve, Final Cut Pro | SRT | Imports as a caption track you can restyle on the timeline |
| A video on your own website | VTT | WebVTT is the format the browser's own video player reads |
| Aegisub, VLC or mpv | ASS | Carries a style and the timing of every word, for typesetting |
| Show notes, a blog post, a quote | Text | The words alone, without timings |
| TikTok, Reels or Shorts | The MP4 with captions burned in | Words in the picture show for every viewer, captions setting on or off |
Free to use: two videos every 30 days with no mark, or $49 once for unlimited videos. Subtitle files are free without limit for videos up to ten minutes, with no account, and downloading them never uses one of your free videos.
Drop the MP4 on this page or on burncaps.app, wait while it listens, check the words in the script, then click SRT. There is no account and no sign-up. SRT, VTT, ASS and text files are free without limit for videos up to ten minutes.
No. The video is opened in your browser and never leaves your device; the only large download is the speech model, once (about 190 MB with a graphics chip, 80 MB without, then cached). The sound leaves only if you choose our speech service, which a phone offers for speed and a computer offers for a language other than English: then it goes in short pieces to Microsoft's MAI-Transcribe in the EU, never the picture, and nothing is kept. You can check all of this in your browser's network tab.
Yes, on a computer: a recording up to 90 minutes and 10 GB (MP4, MOV, M4A, MP3 or WAV) gives its script and subtitle files. Without Pro the first ten minutes are free, and Pro, $49 once, does the whole recording. On a phone the limit is ten minutes and 250 MB.
Yes. Choose a caption language and the lines are translated into any of the 37 languages before you download. Only the transcript text goes to our AI for the translation, never the video or the sound, and ticking Keep everything on this device stops it.
SRT times each caption, not each word: a caption starts with its first word and ends with its last. If you need every word's time, download ASS, which carries each word's timing as karaoke tags, or burn the captions into the video, where every word lights up as it is said.
What it is: a browser tool that burns animated word-by-word captions into a talking video, or cuts it to its best 30 or 60 seconds.
Price: free with every feature, for two videos every 30 days with no mark; Pro, $49 once, gives unlimited videos with no mark. Pro is not a subscription.
Privacy: the video never leaves your browser. The sound leaves only if you choose our speech service.
Files: MP4 or MOV up to ten minutes in; an MP4 with the captions burned in out. SRT, VTT, ASS and text files are free without limit for recordings up to ten minutes. A longer recording, up to 90 minutes on a computer, gives its script and those files: the first ten minutes free, all of it with Pro.
Languages and styles: captions in the language spoken, twelve Indian languages heard on your device, translation into 37 languages, 20 caption styles.
After it listens: correct any word (one click changes it everywhere), add or cut words, one to six words at a time, position, size, text and highlight colours, and names this browser remembers, all free and without listening again.
