How to Dub a Short Video into Another Language with AI

A clip in one language reaches the people who speak it. A dubbed copy reaches the others, without you recording again. AI makes this fast, but a dub is worth posting only if the translation sounds natural and the timing fits. This post shows how a dub is made and what to check.

In short: translate the lines so each is about as long as the original, give every speaker a voice, keep the background sound, replace the captions with the new language and listen to the whole clip before you export.

How a dub is made

1. Get the words. The clip is transcribed, with who speaks when.
2. Translate the lines. Each sentence is rewritten in the new language to take about as long to say as the original. Word-for-word translation often runs long and forces a fast voice.
3. Voice each speaker. A different voice for each person keeps a conversation understandable.
4. Place the lines. Each translated line starts where the original line started and is sped up only as much as it needs, never into the next line.
5. Keep the background. The music and room sound stay under the new voices.
6. Replace the captions with the translated text, timed to the new lines.

Clip-Short does these steps for clips made in AI Clipping. It dubs into English, Spanish, Portuguese and Arabic, uses stock voices (not a copy of your voice) and exports the dub as its own file beside the original. A dub uses the clip's minutes for each language, so a one-minute clip dubbed into two languages uses two extra minutes.

What to check before you post

• Names and numbers. Machine translation changes spelling and units. Read them.
• Jokes and idioms. They often do not carry over. Rewrite the line, or cut it.
• Tone. A serious clip should not get a cheerful voice.
• Timing. Play it once with the original beside it. If a line starts late or runs into a cut, edit the text.
• Captions. Make sure they match what is said, not a different draft.

Which languages to pick

Pick the languages where you can actually reply to comments, or where you already have some viewers. Look at your analytics for the countries that find you, and begin with one language rather than four. If you are not sure, our dubbing guide explains how to choose.

Say it plainly

Some platforms ask creators to label content that is made or changed with AI, especially when it sounds like a real person. A dubbed voice that is not the speaker's own can fall under that. Read each platform's current rule and label if it asks you to; our guide on labelling AI videos lists them.

Questions

Can the dub use my own voice? Not in Clip-Short's clip dubbing, which uses stock voices. Your own voice is available for AI Agent videos on paid plans.

Will the lip movement match? No. A dub changes the sound, not the mouth. It works best on clips where the speaker is not in tight close-up, or with captions that let the viewer follow.

Is a dub the same as captions in another language? No. Captions only translate the text. A dub replaces the voice too. Many viewers like both.
