FAQ
Which languages are supported?
The video can be in Mandarin, Cantonese, English, Japanese, Korean, Spanish, Portuguese, French, German, Indonesian, Thai, Arabic, Filipino or Malay. It can be translated into Mandarin, Cantonese, English, Japanese, Korean, French, German, Spanish, Portuguese, Italian, Russian, Vietnamese or Indonesian. Clone the original speaker works for the first five only; for the other languages, pick a voice from the list. More target languages are on the way.
Can it use the speaker's own voice?
Yes. Choose Clone the original speaker: a clean stretch of their voice is picked from the video automatically and used to speak the translation. Both the video's language and the target language must be Mandarin, Cantonese, English, Japanese or Korean. Before cloning, you must confirm you are the speaker or have their consent.
How is it priced?
By the length of the video: 50 credits per minute, whichever voice you choose, prorated for partial minutes. You need to sign in; failed runs are refunded.
Does the picture change? Will lips match?
The picture stays as it is; only the sound is replaced, without lip sync. When a translation runs long the voice speeds up slightly, and a few spots may hold a frame briefly while the line finishes. Subtitles are timed to the dubbed lines.
Is background music kept?
By default, yes: the voice is separated from the background, only the voice is replaced, and you also get the background track. Choose Remove to keep only the dubbed voice.
Any limits on use?
Only process videos you have the right to use, and never use a cloned voice to impersonate anyone, defraud anyone or for other illegal purposes.
