Video localisation, done properly
One explainer, every language, without re-recording or re-editing a thing.
Subtitles are a compromise. They ask the viewer to read while watching, they cover part of the picture, and they quietly signal that the video wasn't really made for them. Proper localisation means the video speaks the viewer's language — literally.
The catch has always been cost. Re-recording narration in twenty languages, then re-editing every cut to match the new timing, is a project most teams never start. That's the part worth solving.
Translation is the easy part
Translating a script is straightforward. The hard part is timing: the same sentence takes a different number of seconds in German than in Japanese, so a video edited to English narration falls out of sync the moment you swap the voice.
Done properly, localisation re-times each scene to the new narration, so the picture and the voice line up in every language — not just the one you edited in.
Keep the visuals, change the voice
The visuals usually don't need to change — a diagram is a diagram in any language. What changes is the narration and its timing, plus any on-screen text. Separating the story from the language means you produce once and release everywhere.
This is how a single safety explainer can ship in twenty-one languages as the same story, re-narrated and re-timed, rather than twenty-one separate edits.
Localisation in ProdExplainer
ProdExplainer re-generates narration per language in a real neural voice and re-times each scene automatically, across 82 languages. You build the story once; every language version stays in step without touching the visuals. See it in action on the How Scams Work example, which ships in twenty-one languages from a single project.
Frequently asked
- Is this just auto-translated subtitles?
- No. It re-narrates the video in a real neural voice for each language and re-times the scenes, so it plays as a native video, not a subtitled one.
- How many languages are supported?
- 82 languages across 153 locales and accents — the full set of neural voices the platform exposes.
- Do I have to rebuild the video for each language?
- No. You build the story once; each language version is generated from it, so the visuals stay identical and only the narration and timing change.
