AI Video Translator: Dub, Then Lip Sync, in One Studio

A translator is a language pair plus a generate button

An AI video translator is the productized version of “please make this video work in another language.” Under the hood you still get transcription, translation, voice, and a lip sync pass. In the studio you get a language pair and a generate button. Use this page if you think in tools. Use Video Dubbing if you think in post-production terms. Both live on LipSyncing AI so you are not stitching four plugins.

The face stays the speaker you already shot. The mouth should follow the new language, not leftover English visemes. Captions can ride along. This is not a human legal translator. It is a fast first pass for talking heads, walkthroughs, and course chapters.

Translator vs dubbing vs multilingual avatar vs video lip sync

Use AI Video Translator or Video Dubbing when picture is locked and language must change. Use Video Lip Sync when the language is already right and only the wording or vocal quality changed. Use a multilingual avatar (Lip Sync for TikTok / YouTube) when you would rather generate a new line on a saved host than localize a tape.

Turn lip sync off when the video is a screen recording and the mouth is a postage stamp. Keep it on when the face is the product. Do not run a pet meme through the people translator's mouth model — translate the joke, then Talking Cat or Talking Dog.

Dub, then lip sync, in one studio

Proof the script before you burn credits on a bad name. That step is the whole difference between a tool and a plugin chain you regret.

If the translator UI shows the script, treat that screen as an edit bay. You are not required to accept the first draft. Names, jokes, and the last-line CTA are worth a minute of typing.

• Upload a talking-head or VO-forward explainer. Dialogue should be the loudest thing in the mix.
• Set source and target language. Set source manually if the clip is mixed.
• Review the translated text. Fix product names, jokes, and CTAs.
• Keep lip sync on for presenters. Add captions if the market wants both.
• Generate. Proof the first claim. Export the MP4 with the new vocal.
• If picture will still change, wait. Translating a moving cut twice is two bills.

Quality checklist for a translated talking head

A native speaker should not wince at the first sentence. If they do, you skipped script review.

Watch with captions off. If you need the caption to understand the offer, the vocal or the mix failed. Then turn captions on and check they match what you hear.

• Proper nouns survived.
• Mouth timing matches the target language.
• Original dialogue is gone, not ghosted.
• Voice energy roughly matches the on-screen person.
• Legal/medical/financial lines are marked for a human.
• Captions, if used, match the spoken dub.

Credits for localized duration

Same meter. One credit = $0.01 on a plan. First 30 seconds = 150 credits ($1.50). Extra second = 5 credits ($0.05). 45s = 225 credits. 60s = 300 credits. If German runs 6 seconds longer than English, you leave the first block and pay 5 credits a second for the tail. Keep the translation tight.

No free plan; local preview still works. Packs are $0.08 per credit and never expire. Yearly is 30% off, no auto-renew. Subscription credits spend first, then packs. Unused plan credits roll over while the plan is active and cancel if you cancel. Three 30-second locales of the same tape are 450 credits, not one magical bulk discount.

Rights on tapes you translate

Translation does not launder a clip you were not allowed to use. Talent releases should cover localized versions. Clones in the target language need permission for that clone.

A webinar recorded under “internal only” does not become a public localized lead magnet because the translator was convenient. The new language is a new distribution.

• Own the source video or have a license.
• Music beds may be copyrighted separately.
• Do not translate a competitor's ad and republish it.
• Employee videos may need extra approval for new markets.
• Mark AI-altered media where platforms require it.

Common translator failures

Skipped script step, overlapping speakers, and using the translator as a lawyer. It is a studio tool.

Auto-detect on a mixed-language intro will poison the whole file. Set source language. If the first ten seconds are English titles over a Spanish speaker, trim the titles off before you translate.

• Unreviewed names shipped.
• Lip sync off on a close-up face: the feed looks broken.
• Lip sync on a slide deck postage stamp: wasted mouth pass.
• Crosstalk podcast: split speakers.
• Legal contract video without a human: do not.
• Montage dubbed as one file: cut to the talking-head section first.
