Thirty-four markets, one afternoon
Most teams localize the website and stop, because localizing video means a vendor, a spreadsheet of subtitle timings, and six weeks. DemoRiff re-voices the video, matches the mouth movement, swaps the on-screen text and translates the written guide — as one operation.

Re-voiced, not captioned
A full audio replacement in the target language, in a native voice — or your own clone speaking a language you do not.
Mouth movement matched
Where a presenter or camera is on screen, lip movement is re-synced to the new audio so it does not read as dubbed.
The whole asset set
Video, captions, on-screen text, interactive tooltips and the written guide all localize together.
Translated for meaning, with your terms protected
Product names, feature names and interface labels are pinned so they are never translated — nothing undermines a localized demo faster than a translated button that does not exist in the localized product. Everything else is translated for meaning and re-timed, because a sentence that takes four seconds in English may take six in German, and the narration still has to land on the right frame.
- Glossary of protected terms, shared across the workspace
- Meaning-first translation with product context
- Automatic re-timing so narration still matches the action
- Per-language human review and approval before publishing

If your product is already localized, point DemoRiff at the localized environment and it will retake the screenshots and re-record the flow against it. If it is not, on-screen text overlays can be translated in place so the viewer at least reads their own language in the callouts, captions and tooltips.
- Re-capture against your localized environment where available
- In-place overlay translation for callouts and captions
- Right-to-left layout support for Arabic and Hebrew
- Locale-correct number, date and currency formatting
Keeping eleven languages current is the actual problem
Producing one localized video is easy. Keeping eleven of them current through three months of product changes is where teams give up. Because translations are derived from the source, changing the source marks every language stale, shows you exactly which ones, and re-renders them all on approval — with human-corrected languages pinned so your reviewer's work is never overwritten.
- Staleness tracking per language against the source
- Bulk re-render with one approval
- Pin a language to preserve manual corrections
- Per-market analytics so you know which languages earn their keep
The technical detail
- Languages
- 34, including 5 English and 2 Spanish / Portuguese / Chinese variants
- Lip-sync
- Applied to presenter and camera tracks; screen-only video needs none
- Throughput
- Roughly 2 minutes per language, processed in parallel
- Billing
- Localized versions never consume additional video minutes
- RTL
- Full right-to-left support for Arabic and Hebrew
The written guides are the sleeper feature. Every video we publish also becomes a help article, in six languages, with screenshots that are always current. Support ticket volume on onboarding fell by half.
About localization
For most product walkthroughs, yes — the vocabulary is constrained and your product terms are pinned. We still recommend one native review pass per language for anything customer-facing, and the workflow is built for it: reviewers get a side-by-side view, can correct inline, and their corrections are preserved when the source changes.
Because charging again for a video you already paid to produce is how this category gets expensive, and it results in teams localizing two languages instead of eleven. We would rather you publish everywhere and stay on the plan.
Yes. The clone carries your timbre into all thirty-four languages. Whether that is the right choice is a judgement call — in some markets a native presenter builds more trust than a founder with a foreign accent. Both options are one dropdown apart.
