> **Quick answer —** Product video dubbing re-voices a video you already own for each marketplace, keeping the cut intact. Subtitle where video autoplays muted, dub where the player has sound — most catalogues need both, from the same script.[Vitra.ai Universe](https://www.vitra.ai/platform) generates, adapts and translates the whole set.

## The asset already exists

A brand that has made one good product video has usually made exactly one, in English, and it sits on the domestic PDP while eight other marketplaces show stills.

Reshooting per market is not the alternative anyone is actually considering. The realistic choice is between leaving those listings without video and re-voicing the cut you have.

## Dub or subtitle

Placement

Default

Why

PDP gallery, autoplay

Subtitle

Plays muted; sound is opt-in

Marketplace video tab

Dub

User pressed play and expects audio

Social commerce

Subtitle

Muted feed, fast scroll

Paid video ads

Dub plus subtitle

Sound-on and sound-off both occur

Long-form demo

Dub

Several minutes of reading is a poor experience

Most catalogues need both, which is less work than it sounds because both come from one translated script. Getting the script right once is what makes both cheap.

## Holding one voice across a catalogue

Forty product videos voiced by whoever was available produces forty brands.

Voice is part of identity in the same way type and colour are, so fix it per language and keep it. [Video dubbing](https://www.vitra.ai/features/video-dubbing) can hold a consistent voice across a library, which matters most for a shopper who watches three videos on your store in one session. Speed matters too. A translated script that runs 30% longer than the English forces either a rushed read or a re-cut, and the fix is at translation stage — write to the timing, not to the page.

## The claims problem

This is the part that is specific to commerce rather than to video.

A product claim is regulated by the market it is shown in. A comparative claim that is ordinary in one country needs substantiation in another; a health or efficacy phrase may be prohibited outright; units and warranty terms differ.

None of that is caught by translating faithfully, because a faithful translation of a non-compliant claim is still non-compliant.

So review the script per market before rendering, not the finished files afterwards. And keep the terminology fixed with a [translation memory](https://www.vitra.ai/features/translation-memory) so the product name and feature names do not drift between the video, the listing and the [PDP video](https://www.vitra.ai/features/video-creation) made next quarter.

If no video exists yet, [PDP video generation](https://www.vitra.ai/e-commerce/pdp-video-generation) makes one out of the listing before any of this applies.

Where the product in shot differs by market, the shoot itself has to change — [automotive walkaround video](https://www.vitra.ai/automotive/automotive-video-walkaround) is the clearest version of that problem.

## FAQ

**Should product videos be dubbed or subtitled?** Subtitle where video autoplays muted, such as PDP galleries and social feeds. Dub where the viewer pressed play and expects sound, such as a marketplace video tab or a long demo. Both come from one translated script.

**How do you keep a consistent brand voice across product videos?** Fix the voice per language and reuse it across the library rather than casting per video. A shopper who watches three videos in one session hears whether the brand sounds like three different companies.

**Why do translated video scripts break the timing?** Because most languages run longer than English, commonly by a fifth to a third. Writing the translation to the existing timing avoids either a rushed read or re-cutting the video for every market.

**Do product claims need re-checking for each market?** Yes. A faithful translation of a claim that is not permitted locally is still not permitted. Comparative claims, efficacy wording and warranty terms all vary, so the script needs market review before rendering.
