How to Translate a YouTube Transcript into Another Language
Read or repurpose a video in a language its captions were never written in.
CaptionFetch guides · About the publisher
YouTube's own auto-translate captions are convenient but ephemeral — they only exist inside the video player. If you want a translated transcript as an actual document you can read, edit, or download, you need a tool that translates the extracted text itself.
Steps
- Paste the video URL into CaptionFetch and fetch the transcript in its original caption language.
- Open the translation option (available on Plus and Pro) and choose your target language. Usage allowances and provider availability apply.
- The translated transcript appears alongside the original — translation is non-destructive, so you always keep the source text and can toggle between the two.
- Download the translated version in TXT, SRT, VTT, JSON, CSV, or PDF, or save it to your library if you are signed in.
Why keep the original alongside the translation
Machine translation is good but not perfect, especially for idioms, technical jargon, and names. Keeping the source transcript next to the translation means you can spot-check anything that reads oddly against what was actually said, rather than trusting the translation blind.
Translating subtitle files, not just plain text
If you translate an SRT or VTT export, the timestamps are preserved — only the caption text changes. That means a translated subtitle file still lines up with the video, which matters if you are producing subtitles for viewers in another language rather than just a translated reading copy.
Worked example: numbers, names, and negatives
Consider this original sentence: “Leave the valve closed for 15 seconds; do not turn the blue handle.” Before approving a translation, check that 15 remains 15, seconds have not become minutes, and the instruction still says not to turn the handle. Fluent grammar alone is not enough to catch an unsafe reversal.
Keep product names and technical abbreviations consistent. If “Bluebird” is the name of a device in your recording, translating it as a bird species changes the meaning. A glossary or a note to your reviewer can distinguish names from ordinary words.
Check readability against playback
A translation can be longer than the original while using the same timestamps. Play the exported subtitles with the recording and check that each cue remains readable before it disappears. Shorten phrasing without losing meaning, split an overlong cue where the editor supports it, and preserve a copy of the original track.
For publication, ask a fluent speaker to review idioms and terminology. For consequential instructions, use a suitably qualified reviewer. Translation does not grant new rights to the source; obtain permission or another lawful basis for translated publication.
