AI video dubbing and translation

Dub a lesson, interview or story into another language without rerecording every line.

Choose how your video sounds

Dub uses a selected preset voice. Choose a compatible voice and target language, and use speaker detection for conversations. Voice Clone is a separate choice for authorized original or supplied voices.

A short workflow

  1. Upload an MP4, MOV, MKV or WEBM, or provide a supported public HTTPS video address.
  2. Select Dub, Original language and Target language. Set your voice and Speaker detection.
  3. Choose whether to create subtitles, create the job and review its quote.
  4. Confirm the accepted cost when ready. Review the completed video and download available outputs.

Languages and inputs

  • Selectable languages: English, Brazilian Portuguese, European Portuguese, Spanish, French, German, Italian, Japanese, Korean and Simplified Chinese.
  • Video upload: up to 10 GB. A public link can fail if its source blocks access; upload a permitted copy instead.
  • A target-language option does not guarantee every voice supports that language.

What needs your review

AI can misread names, idioms, emotion or overlapping voices. Review accelerated phrases and timing warnings. Dubbing does not add customer lip sync, and processing start time depends on capacity.

Questions and answers

Does D-UB change mouth movements?

Customer lip sync is unavailable. Voice cloning keeps the original mouth movements; timing adjustments are not lip sync.

Can I add captions to a dub?

Yes. Enable the optional subtitle choice for the new job. It is off by default for Dub and Voice Clone.
