|---|---|---|
| video | Yes | Video to translate and dub. The video must contain audible speech. |
| target_language | Yes | Target language for the translated speech. |
| source_language | No | Language spoken in the source video. Default: auto. |
| keyterms | No | Up to 10 names or terms to help speech recognition and terminology preservation. |
How to Use
- Upload a video — Provide a video with clear, audible speech.
- Choose the target language — Select the language for the translated dialogue.
- Set source language optional — Leave it on
autoor choose the spoken language manually. - Add keyterms optional — Include important names or terminology when needed.
- Submit — Generate and retrieve the dubbed video.

| Video Duration | Price |
|---|---|
| 10s | $1.20 |
| 30s | $3.60 |
| 60s | $7.20 |
Input duration is rounded up to the next whole second for billing.
Language selection and keyterms do not add separate charges.
Best Use Cases
- Training and educational videos — Localize lessons and instructional content.
- Creator content — Translate spoken videos for multilingual audiences.
- Product demonstrations — Dub product walkthroughs and presentations.
- Marketing videos — Adapt campaign content for different languages.
- Business presentations — Create localized versions of internal or external communications.
Pro Tips
- Use videos with clear speech and minimal background noise.
- Keep faces well lit and clearly visible for better lip synchronization.
- Specify the source language when automatic detection may be uncertain.
- Add important names, brands, and technical terms as keyterms.
- Review translated speech and terminology before publishing.
Notes
- Input videos must be no longer than
10minutes. - The source video must contain audible speech.
- Select a supported base language. Separate regional accents are not available.
- Up to
10keyterms are supported. - Each keyterm can contain up to
50characters and5words. - Keyterms must not contain
<,>,{,},[,], or backslashes. - Keyterms guide speech recognition and terminology preservation; they are not source-to-translation pairs.
