Lectures, sermons, podcasts, webinars and interviews: on a computer, Burncaps writes the script and the subtitle files of a recording up to 90 minutes and 10 GB. The first ten minutes are free, and Pro, $49 once, does the whole recording. The video is never uploaded.

The page reads the sound out of the file a slice at a time and keeps it as 16 kHz mono, so a 10 GB camera file costs time to read, not memory. The picture stays where it is, on your device, and the page shows how much it has read.
Without Pro, it listens to the first ten minutes, ending at the last pause in their final minute rather than in the middle of a word. The script and every subtitle file hold that part, free and with no account.
With Pro on the device, the whole recording is heard. Sign in to Pro after the free part and Listen to the rest carries on from where it stopped, without dropping the file again, while the script grows as it is heard.
Writing a new video means your browser holds the file in memory while it encodes, and a longer recording is more than many computers can hold at once. Subtitle files need only the sound, which is why a long recording gets them and not a burned-in copy. That is the same with Pro and without. We have no date for burned-in video past ten minutes.
Listening on your computer has no limit and keeps the sound on it; a long recording just takes longer that way. Our speech service, if you choose it, has an allowance of sound in any 30 days: 25 minutes without Pro, five hours with Pro. When a Pro recording needs more than is left, the page says so before any sound is sent, and offers to listen on the computer instead wherever a model in the browser writes that language.
Free to use: two videos every 30 days with no mark, or $49 once for unlimited videos. Subtitle files are free without limit for recordings up to ten minutes, and the first ten minutes of a longer one are free; Pro does the whole of a recording up to 90 minutes. Pro is one payment, not a subscription.
On a computer, a recording up to 90 minutes and 10 GB gives its script and its SRT, VTT, ASS and text files. On a phone, recordings up to ten minutes and 250 MB.
The first ten minutes of a long recording are free, with no account. Pro, $49 once, does the whole recording, up to 90 minutes. Recordings up to ten minutes get their subtitle files free without limit.
Not today. Video with captions burned in, and the best 30 or 60 seconds, work on recordings up to ten minutes, with Pro and without. Writing a new video means your browser holds the file in memory while it encodes, and a longer recording is more than many computers can hold at once. Subtitle files need only the sound. We have no date for burned-in video past ten minutes.
MP4, MOV, M4A, MP3 and WAV files with AAC, MP3 or plain sound in them. A recording in another format, or one with another kind of sound, can be saved as one of these first, or trimmed to ten minutes.
It depends on your computer and the language. The page shows how much of the sound it has read, the script grows as it is heard, and the page asks the browser to keep the screen awake while it listens. Keep the tab open: a long recording is not kept in the browser, so a closed tab means dropping the file again.
No. The video never leaves your device; only its sound is read, a slice at a time, in your browser. The sound leaves only if you choose our speech service, in pieces of up to 30 seconds with nothing from the picture, to Microsoft's MAI-Transcribe in Ireland, and nothing is kept.
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.
