Video ad localization: how to adapt one ad for Korean, English, and Japanese
A practical workflow for adapting the script, footage, captions, and call to action—not just translating the voiceover.
Video ad localization starts with a question: Will the words, footage, and next step still make sense together in each language? Translating the voiceover alone may leave captions, on-screen text, offers, or the call to action out of step. Vendors describe workflows that also address dubbing, lip-sync, and reframing; those are production options, not independently verified improvements in ad performance. 2 3
A video ad localization workflow you can brief
1. Lock the meaning, not the wording. Write down the product need, what the footage actually demonstrates, and the action viewers should take. Keep those points consistent across versions while allowing each script to be written naturally. List every price, offer, and product claim in the source ad so the team can check whether it belongs in each destination version.
2. Match each line to a shot. Put the script beside a shot list. If a translated sentence continues after the relevant action has ended, shorten the line or adjust the edit. Decide whether each version needs recorded speech, dubbing, or no spoken line at all. One vendor presents translation and re-voicing, lip-sync, and reframing as a workflow; that does not mean every ad needs all three. 2
3. Treat text and framing as part of production. Review captions, overlays, and the final call to action separately from the spoken script. Check that text fits, stays clear of the subject, and remains visible if the video is reframed for another placement. Watch once without sound and once with sound. Vendors identify captions, on-screen text, and aspect ratio as elements that may need adaptation. 2 3
One shot, three production decisions
The following is an illustrative concept, not a real campaign or evidence of market preferences. A hand switches on a desk lamp; the person then sits down. A short-form ad could reuse that footage while making separate decisions about the line, caption timing, and final prompt.
| Version | Line and shot | Caption or overlay | Final call to action |
|---|---|---|---|
| Korean | As the switch is pressed: “책상에 불을 켜고, 시작하세요.” | Bring in the caption after the lamp lights; keep the lamp unobscured. | “조명 살펴보기” |
| English | On the switch and the following seated shot: “Light your desk. Get started.” | Show the first sentence on the switch, the second as the person sits. | “See the lamp” |
| Japanese | From the lit lamp into the seated shot: “机を照らして、始めよう。” | Leave room for the sentence without placing text over the lamp. | “照明を見る” |
These are draft creative choices to test with local writers against the actual edit—not rules about how people in any country respond to ads. If the footage cannot support a line, change the line or the footage rather than relying on a fluent translation to hide the mismatch.
Pre-publication checklist
- Have in-language reviewers read the spoken and on-screen copy against the edit, not in a document alone.
- Verify that claims, prices, offers, and the destination page match the version being published.
- Check the caption and subject at the intended screen size, with sound off and on.
- Confirm that the final call to action describes what the destination page actually lets viewers do.
- If you use automatic localization, review the output and check the feature’s eligibility and language coverage for your campaign. For example, Amazon Ads’ published Sponsored Brands announcement specified particular source languages and marketplaces at launch; it was not a universal localization option. 1
The goal is not three identical-sounding edits. It is three edits in which the line, visible action, readable text, and next step agree.
