Use YouTube auto-translate for one subtitle language
Open a captioned video, select Settings and then Subtitles/CC. If Auto-translate is offered, select it and choose a language. Options depend on the video and the device.
This is the quickest starting point when you only want to understand the text. Translation quality depends on the source captions; names, technical language and accents need extra care.
Use dual subtitles to compare the original
Install TransParrot in desktop Chrome when you want to keep the original words beside their translation. Select a target language in the extension and turn on bilingual subtitles.
The transcript gives you another way to read: search a phrase, switch text language and click a line to return to the corresponding moment. This is useful for lectures and language study.
Turn on translated audio when you prefer listening
Choose an available target voice and enable translated audio. Adjust the original audio separately so you can hear the output clearly. Some sentences may need time to prepare.
Generated speech is a listening aid, not a copy of the creator’s voice. TransParrot does not export dubbed video files or create lip-synced footage.
Check the result before using it elsewhere
Replay any sentence you plan to quote, especially a name, number, instruction or technical claim. Machine translation can sound fluent while missing context.
If the video has no captions, these caption-based steps cannot translate it. Look for a creator-provided transcript or a separate authorized transcription workflow.
Questions, answered
Can I translate a video into English?
Yes, select English as the target language when a source caption track is available. The same caption and voice-availability limitations apply.
Do I have to download and upload the video?
No. The viewer extension works on the YouTube page and processes captions through the TransParrot service.
