What it does
translate-and-dub translates the speech in one video into other languages and re-syncs the speaker’s lips to the dubbed audio. You get one MP4 per language, labelled with its language. It works from a local file, a public URL, or a YouTube, TikTok, Instagram or Facebook link.
When to reach for it
Try
- “Dub this YouTube video into Spanish and Brazilian Portuguese”
- “Translate ./keynote.mp4 into Japanese”
- “Make a German version of https://example.com/demo.mp4”
What you need
- The sync. MCP server connected, or
SYNC_API_KEYset. The setup skill walks you through either. - A video with its original speech on the audio track.
Common questions
Which languages are supported?
The agent checks the live list before quoting. If a language isn’t there, it names the closest one that is.
How is it priced?
By the length of the source video, once per language. The quote shows the breakdown per language and the total. If external voice-provider charges are excluded, the agent says so.
Is on-screen text translated?
No. Titles, captions and logos stay as they are. Only the speech changes.
One language failed.
Each language is its own job, so the others still finish. The agent reports which one failed and why.
Dubbing failed with a voice-provider error.
If you connected your own ElevenLabs key to sync., that key’s credits or validity are the usual cause.
It wouldn't dub a music video.
Copyrighted songs and music videos need the rights holder’s permission. Use a video you own or are licensed to localize.
It’s working if
- The languages are checked before the quote.
- There’s one paid job per language, never a resubmit to check progress.
- Each output link is labelled with its language.
