Two kinds of caption track
A creator-provided track was uploaded or written by the person who made the video, or by someone they hired or a community contributor they approved. An auto-generated track was produced by YouTube's speech recognition, without a person reviewing it.
When a transcript tool loads a video, it picks from the tracks that video offers. If a creator track exists in your language, it is normally preferred. If only an automatic track exists, you get that one, and a good tool tells you so.
How to tell which one you have
In the language list, automatic tracks carry an auto-generated label. On YouTube's own player the caption settings show the same wording, for example English (auto-generated). If a language appears without that label, it is a creator track.
The caption checker shows the languages a video offers before you extract anything, which is the quickest way to see what you are about to rely on.
Errors worth expecting from automatic captions
- Proper names. People, places, brands and product names are the most common casualties, especially uncommon ones.
- Numbers and dates. "Fifteen" and "fifty", or years spoken quickly, are easy to confuse.
- Technical terms. Specialist vocabulary is replaced with a similar-sounding common word.
- Homophones. Words that sound alike can be swapped when the surrounding context is thin.
- Accents, noise and crosstalk. Background music, echo and several people talking at once all lower quality.
- Punctuation and sentence breaks. Lines follow the timing of speech, so sentences may be split or run together.
- Sound labels. Cues such as [Music] or [Applause] may be mixed into the text.
None of this makes an automatic transcript useless. It means the text is a reliable pointer to where something was said, and a less reliable record of the exact words.
Creator captions are better, not perfect
A person has usually checked a creator track, so names and numbers are more likely to be right and the punctuation is more natural. But creators make typos, caption tracks are sometimes machine-generated and uploaded without editing, and a translated track may be rougher than the original language. Treat a creator track as a stronger starting point, not as proof.
A short check before you quote or publish
- Search the transcript for the passage you need, and note its timestamp.
- Open the video at that moment and listen to it, not just read it.
- Correct names, numbers and terms from the audio or an authoritative source.
- Keep the video link and the timestamp with the quotation so a reader can verify it.
- Do not present a summary or a translation as the speaker's exact words.
The quote finder searches a whole transcript for a phrase and returns the surrounding lines with timestamps, which makes step one quick. For citations see how to cite a YouTube video.
What changing the file format does not change
Exporting to TXT, SRT, VTT, JSON, CSV or Markdown only changes the layout. If a name was mis-heard in the caption track it will be mis-heard in every export. To tidy a transcript for reading, the cleaning guide explains what can be removed automatically, and the missing transcript guide covers videos with no usable track.
