What Is AI Video Translation?

AI video translation is the process of taking a finished video and reproducing its spoken audio in another language automatically — transcribing the original speech, translating it, generating a voice that sounds like the original speaker, and optionally reshaping the speaker's mouth movements and adding translated subtitles. The footage stays the same; only the language changes.

How the process works

1. Transcription — the AI turns the original audio into a timed script
2. Translation — the script is translated segment by segment, using the surrounding context rather than word-by-word substitution
3. Voice generation — the speaker's voice is cloned so the translated audio keeps their tone and delivery
4. Lip-sync — the mouth region is regenerated so the lips match the new language
5. Subtitles — translated subtitles, including animated word-by-word styles, can be burned in

What it is not

• Not subtitles on their own. Subtitling leaves the original voice track in place; translation replaces it.
• Not an AI avatar. Nothing is re-shot with a synthetic presenter — your real creator, product and setting are preserved.
• Not a black box. In GeckoDub the translated script is shown to you before dubbing, so you can correct it.

How GeckoDub handles it

GeckoDub covers 70+ languages and dialects. Voice cloning preserves emotion and tone, GoSync 3.0 lip-sync is available on every plan, and animated subtitles are auto-timed to the new audio. Custom Glossary and Brand Kit rules lock your product names and subtitle styling in place, and the proofreading editor lets you fix the translation before the final dub.

Why it matters for video ads

A winning ad is expensive to produce and market-specific to translate. AI video translation lets you re-voice a creative that already converts instead of re-shooting it per market — so testing a new country costs a render, not a production day.
