How to translate a video, keeping the voice and matching the lips

Translate a video with AI so each speaker keeps their own voice and the lips match the new words. Your three options, the steps, the limits and the checks.

Checked against the product on

There are three ways to translate a video, and they cost very different amounts of effort: subtitles, a dub, or a dub with the lips re-synced. This guide explains when each is enough, then walks through the full version on make.ad’s Language swap page.

01Subtitles, a dub, or a dub with matched lips

02Translate a video with Language swap

Language swap is ElevenLabs dubbing followed by a lip re-sync of the original picture. Each speaker keeps their own voice, now saying the new words.

  1. Upload the video, up to 10 minutes long.
  2. Pick the language it should speak.
  3. Leave Match the lips on if people talk to camera. It re-syncs videos up to 4 minutes long; a longer video is still dubbed, with its original lips.
  4. Tick the consent box: each speaker’s voice is cloned to say the new words, so you need the right to use them.
  5. Check the quote in credits, and start. If the lip re-sync fails, you keep the dub and the lip sync’s credits come back.

03The 32 languages

Language swap speaks English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Hindi, Arabic, Russian, Dutch, Polish, Turkish, Indonesian, Filipino, Malay, Vietnamese, Swedish, Danish, Finnish, Norwegian, Greek, Czech, Slovak, Romanian, Bulgarian, Croatian, Ukrainian, Hungarian, Tamil.

04Check it before it goes out

  • Have a native speaker watch it once. Machine translation gets the words right more often than the tone, and slogans rarely survive word for word.
  • Watch the mouth on close-ups, where a re-sync is most visible.
  • Check names, prices and anything legal: those should be checked by a person, not assumed.
  • Burn captions in the new language for sound-off viewers.

05Only the audio? Translate or change the voice

For a recording with no picture, Audio’s Translate does the same dub, in the same voice, without the lip step. Voice change says a recording again in another voice, keeping your words, pauses and feeling, for up to 5 minutes.

To make a new ad in another language from scratch rather than translate one, pick the language on the brief form: the script is written, sung or read in it.

Questions

Does the speaker keep their own voice?
Yes. Each speaker’s voice is cloned to say the new words, which is why Language swap asks for your consent first.
How long a video can I translate?
Up to 10 minutes. The lips are re-synced on videos up to 4 minutes; a longer one is dubbed with its original lips.
What does it cost?
It is priced in credits by the minute, and quoted before it starts. Plans start at $20 a month.
Can I translate subtitles only?
make.ad transcribes speech in the language it was spoken, and Caption burns in the words you give it, so you can paste in a translation you trust before burning it in.
