Two real results, side by side: one from a YouTube video's captions, one from an Instagram Reel's audio.
Convert a video to text →Our tool works with YouTube, TikTok and Instagram links, but it doesn't treat them the same way. For a YouTube video we read its captions. For TikTok and Instagram we use speech-to-text: it listens to the audio and writes down what is said. To show the difference, we ran two NASA videos through the tool on 2 October 2026. NASA videos are public domain, so we can show the results here as they came back.
The lines are short, sometimes one or two words, because captions are cut to fit on screen. At 0:25 the captions name a speaker, [News Reporter]. That label is in NASA's captions; we just keep it.
These lines are longer and break where the speaker pauses, not where a screen would. There are no names, because speech-to-text writes down words, not who said them. The numbers came out as digits: “2024 YR4” and “200 to 250”. Later in the Reel, the date reads “December 22, 2032”.
| YouTube | TikTok and Instagram | |
|---|---|---|
| Where the words come from | The video's captions | The audio, by speech-to-text |
| Line length | Short, to fit on screen | Longer, split at pauses in speech |
| Speaker names | Only if the captions include them | No |
| Music with no talking | Often marked [music]; automatic captions may add a stray word | The tool says it heard no one talking; the try does not count |
Both give you the same things at the end: the text with times, a short summary, and TXT, SRT and VTT downloads. One more difference: a YouTube video with no captions at all gives no transcript. The tool tells you why, and that try does not count.
A list of lines, each with the time it starts, plus a short summary. You can copy the text or download it as TXT, SRT or VTT. The two examples on this page show real output.
For YouTube, from the video's captions. For TikTok and Instagram, from the audio: speech-to-text listens to the video and writes down what is said.
In our Reel example, yes: 2024 YR4, 200 to 250, December 22, 2032. On YouTube the numbers are whatever the captions say. Check any figure you plan to publish against the video.
