One source video, 28 localized versions, no re-recording. Here is how.
How to localize video into 28 languages without re-recording
Localization is where most video budgets break. The first version is reasonable. The tenth version, in the tenth language, costs about as much as the first: new translation, new voice actor, new studio time, new edit. So teams localize the top three markets and quietly skip the rest.
There is a better way. Start from one source video and produce localized versions (voiceover and on-screen text) in 28 languages, without re-recording anything. Here is the workflow.
Why traditional localization is so expensive
The cost is structural, not incidental. In a traditional pipeline, every language repeats nearly the whole production:
- A translator adapts the script.
- A native voice actor records it, in a booth, with direction.
- An editor re-times the edit to fit the new audio.
- Someone re-renders and QAs each version.
Multiply that by 28 and the budget (and the calendar) collapses. So localization becomes a privilege reserved for the biggest markets.
The single-source approach
The shift is simple to state: keep one source, generate the variants. Because Interlace builds the video from a script rather than a fixed recording, a new language is a regeneration, not a reshoot.
That means the voiceover and the on-screen text both adapt. You are not slapping subtitles over English narration. Each version has narration in the target language and text rendered to match.
Step 1: Build the source video well
Localization quality starts with the source. Get the English (or original) version right first: clear script, clean scenes, sensible pacing. Every language inherits this structure, so time spent here pays off 28 times over.
A tip: keep sentences self-contained. Narration that relies on a clever turn of phrase can translate awkwardly. Plain, declarative lines localize cleanly.
Step 2: Generate the localized versions
From your finished source, choose your target languages. Interlace produces a localized voiceover and localized on-screen text for each, from the same source, in one flow. No booking a booth, no waiting on a voice actor's calendar.
This is the step that used to take weeks per language and now takes minutes for all of them.
Step 3: Keep the voice consistent, or local
You have a choice. Keep the same voice across languages where that matters, or pick a native-sounding voice per language where local familiarity matters more. For a global product brand, a consistent voice can reinforce identity. For regional training, a native voice often lands better. Both are available from one source. (Recording your own voice is in early testing, available soon.)
Step 4: Review each version
Translation is not the same as localization. A fluent translation can still miss a cultural cue or use the wrong register. Where you can, have a native speaker review the versions that matter most. Send the reviewer a share link: they leave a comment on the line, you regenerate that scene, and version history keeps the record straight.
You do not need a reviewer for all 28 before you ship. Prioritize the markets that count, and let the rest follow.
Step 5: Export and deliver
Export each version at the resolution you need, as an MP4 or as a SCORM 1.2 package for your LMS. Because every version comes from one source, they stay visually consistent: same brand, same structure, same quality, in every language.
What changes when localization is cheap
When the tenth language costs a fraction of the first, the calculus flips. You stop rationing languages. The regional team that always felt like an afterthought gets the same onboarding video as headquarters. A product launch goes out everywhere at once, not in waves as budget allows.
Localization stops being a line item you ration and becomes something you simply do.
Try it with two languages first
Build one video, generate it in a second language, and watch the voiceover and on-screen text adapt. Then add the other 26.
