Your best ad only speaks one language. Here is how to localise it without a reshoot, while keeping the brand sounding like itself.

What you get

The same ad localised for five markets.

Time to read

About 4 minutes. Each step works with any toolset.

​
What you need

  • A finished master ad
  • A native speaker per language for the script
  • A voice model, and lip-sync for on-camera shots

​
Steps

1

Lock the master cut

Finish the ad in one language first. Every change after this point has to be made five times.
2

Translate for speech, not for print

Have each script adapted by someone who speaks the language, so lines fit the same timing and sound natural out loud.
3

Voice each version

Generate the voiceover per language with the same voice, or a consented clone of your presenter, so the brand sounds consistent.
4

Lip-sync the on-camera shots

Where someone speaks on screen, run lip-sync so mouth movement matches the new audio.
5

Swap on-screen text and captions

Replace every caption, title and end card per language, and check that longer words still fit the layout.
Leave room in the timing. Some languages run longer. Leave a beat of breathing room in the master so translated lines fit.
Avoid this: translating the captions only. Subtitles alone leave the voice in the original language. If the ad is voice-led, localise the voice too.

​
Before you publish

  • Lock the master cut
  • Translate for speech, not for print
  • Voice each version
  • Lip-sync the on-camera shots
  • Swap on-screen text and captions
