Corporate video translation

Translate your training videos. Keep the presenter your team knows.

Upload an onboarding, product or training video and choose one of 28 languages. DubSync does the spoken part of video localization: it translates the speech, gives each presenter a voice created from their own, keeps the background audio and returns a dubbed MP4 for your learning platform, intranet or help center.

Upload a training video

Subtitle, re-record or dub

Three ways to translate a training video, and where dubbing fits.

Corporate video translation comes down to three options. They combine well: captions on everything, a dub for the videos people have to follow closely.

  • Translated subtitles

    • Viewers read while they watch
    • Easy to correct later

    Usually the lowest-cost option, and a wrong line can be fixed afterwards. Reading is hard when the video shows a machine, a screen or a pair of hands.

    Dub vs sub for creators

  • A new recording per language

    • Script reviewed before filming
    • A shoot for each language

    A local presenter records the video again from a translated script, so the wording can be checked before filming. A shoot and an edit per language suits a few high-stakes videos better than a whole library.

  • An AI dub of the video you have

    • Same presenter, same footage
    • Wording can't be corrected by hand

    The speech is translated and spoken again in a voice created from the presenter's own: similar, not identical. Picture and background audio stay. The translation is automatic, so the review below matters.

    How to dub a video

DubSync does the third: one dubbed MP4 per language, with no visible watermark. It doesn't make subtitles or transcripts, so add captions for deaf and hard-of-hearing viewers in your video platform.

Fit check

Which company videos dub well, and which need care.

Hear a product demo change language

Play this demo clip, an AI-generated scene with a fictional founder, then switch the language under it. Both dubbed tracks also have the lip-sync add-on, so the speaker's mouth follows the new words. A dub without it changes only the speech and leaves the picture as recorded.

Screen recordings and narrated slides need no lip-sync. For a leader speaking straight to the camera, you can add it to a finished dub of up to 5 minutes: optional, priced per minute for the whole video, with the quote shown before it starts. How the lip-sync add-on works

What is said: This is our product demo. We recorded it once, and every customer watches it in their own language.

What is said: Esta es nuestra demostración del producto. La grabamos una vez y cada cliente la ve en su propio idioma.

What is said: Esta é a demonstração do nosso produto. Gravamos uma vez e cada cliente assiste na sua própria língua.

Works well

  • Onboarding and welcome videos with one or two presenters.
  • Product walkthroughs and software screen recordings explained by voice.
  • Customer how-to videos for a help center or a sales team.
  • Recorded talks and leadership updates with clear audio.

Take care

  • Slides, labels and captions in the picture: a dub changes the audio only, so re-export them from a translated deck.
  • Acronyms, product names and internal jargon: there is no glossary, so listen for each one in the review.
  • Role-plays and meetings where people talk over each other: voices can get mixed up, and everyone who speaks has to agree to the dub.
  • Courses bought from a training vendor: they are licensed, not yours, so dub them only with the vendor's written permission, which has to cover the presenters' voices.
  • Safety, legal and compliance wording: see the next section.

Safety and compliance training

Wording that protects people needs a qualified reviewer.

A safety video is dubbed so that people understand it, which is why the dub has to be checked. The translation and the speech are automated, and DubSync's terms say they may contain errors.

  • Give the review to a native speaker who knows the subject: a safety officer, a compliance lead or a local trainer. A bilingual colleague from another team is not the same thing.
  • Start with the sentences that carry risk: limits, quantities and units, the order of steps, every never and always, names of chemicals and equipment, legal definitions.
  • A wrong sentence can't be fixed in the dub. Re-record or cut it in the original and dub the new file, which uses its minutes again.
  • Record who approved each language version and when, as you would for a translated written procedure.

If no qualified reviewer is available for a language, don't train anyone on safety or compliance from an unreviewed dub. A professionally translated script or a session with an interpreter is the safer choice.

Before you upload

In a company video the voice usually belongs to an employee: a trainer, an engineer, a founder. The dubbed voice is created from theirs, and a general media waiver may not cover that. A short release should settle four things.

  • The use

    An AI voice is created from their recording to dub named videos or a named series, not everything they ever record.

  • The languages and the audience

    Which languages, and who sees the result: staff, customers or the public.

  • How long

    How long the dubs stay in use, and what happens when the person leaves: the videos stay for a set time, are recorded again or are retired.

  • How to withdraw

    How they can take consent back later, and who then removes the dubbed versions.

DubSync's acceptable use policy asks you to confirm most of this before each dub: that every voice owner agreed to the use, the target languages, where the video is shown and for how long. Saying no has to be a real option. The UK's data-protection regulator says consent is usually not an appropriate basis for using personal data where there is a clear imbalance of power, and it names employers: staff may feel they have no choice. Employers are not banned from relying on it, so make refusal easy.3

Name the uses plainly. In California, for performances from 2025 on, a contract clause that lets a digital replica of a person's voice stand in for work they would otherwise do in person can be unenforceable when it doesn't describe the intended uses in reasonable detail and no lawyer or union represented the person.4 Whether that reaches a dub is a question for your lawyer. Laws differ by country and state, and this page is not legal advice.

Internal and confidential footage

Where the file goes, and how long it stays.

  • It leaves your network

    An upload goes to DubSync's private storage, and the video and its audio are sent to a contracted dubbing processor. With lip-sync, the dubbed video is also processed by contracted lip-sync processors. Processing may happen in another country, under contractual safeguards.

  • It is deleted on a schedule

    Source files are scheduled for deletion after 7 days and dubbed videos after 30 days. Download each MP4 and keep it in your own systems: DubSync is not an archive.

  • You can delete sooner

    Deleting a project removes its stored media and requests deletion of the processor's dubbing records. You can also clear all your content or delete the account.

  • The consent record stays

    Your confirmation that every speaker agreed is recorded for each project. It may be kept after the media is gone, as proof of the authorization given.

The details are in the privacy policy, which also says how to ask which processors handle your data.

A rollout that starts small

Dub one module, review it, then do the rest.

  1. Pick one module and one language

    Start with a short, typical video and the language most of your learners speak. It shows how your presenters, jargon and audio come through before you commit a library.

  2. Export and upload the finished file

    MP4, MOV or M4V with the final mix, up to 150 minutes and 1 GB. The spoken language is detected for you. You see the input minutes and the cost first, and nothing starts until you confirm your rights and every speaker's consent.

  3. Review it before anyone learns from it

    A native colleague who knows the product is enough for a welcome video. Safety and compliance content gets the qualified review described above.

  4. Label the dubbed version

    Say that the voice was dubbed with AI, on screen at the start of the video or next to the player. In the EU this can be a legal duty. Under the AI Act, an organization that uses an AI system to make audio or video that counts as a deep fake has to disclose that it was artificially generated or altered, clearly and by the viewer's first exposure.5 The definition covers AI-made or AI-altered content that resembles a real person and would falsely appear authentic.6 The rule has applied since 2 August 2026. The Commission's guidelines are not binding and don't mention dubbing, but their deep-fake examples include voice-cloned audio of a podcast's regular presenters and a realistic AI avatar of a CEO congratulating employees, and they say no intent to deceive is needed.7 Whether a faithful dub counts is still a legal question, so a label is the cautious choice. YouTube lists cloning your own voice for a dub among the examples that need no disclosure.8 An employee's voice is not your own, so label public videos too.

  5. Add the MP4 where people learn

    Upload the file to your learning platform, intranet or help center as a language version, and translate the title, the description and the quiz yourself. Each further language is its own project and uses the video's minutes again.

28 target languages

Check that your team's languages are on the list.

Vietnamese, Thai, Filipino, Hungarian and Bengali are not offered, and there are no regional variants: one Spanish, one Portuguese. The original doesn't have to be in English.

Questions

Questions before you start

How do I translate a training video into another language?

Export the finished video, upload it and choose the target language. The speech is translated and spoken again in a voice created from the presenter's own, and you download a dubbed MP4 for your learning platform.

Is an AI dub accurate enough for safety or compliance training?

Not without review. The translation is automatic and can contain errors, and there is no script editing to correct one. Have a qualified native speaker who knows the subject approve every safety, legal or compliance video first.

Do we need permission from the employee who presents the video?

Yes. The new voice is created from theirs, and you confirm every speaker's consent before each dub starts. Get it in writing, name the languages and the audiences, and make sure the person could have said no.

What happens to a dubbed video when the presenter leaves the company?

The release decides, so settle it before the first dub: the videos stay in use for a set time, are recorded again or are retired. If the person later withdraws consent, take the dubbed versions down. DubSync's acceptable use policy expects prompt action when a voice owner revokes consent.

How long does DubSync keep our training videos?

Source files are scheduled for deletion after 7 days and dubbed videos after 30 days, or sooner if you delete the project. Download each MP4 and keep it in your own systems.

Does it translate slides, quizzes or the course package?

No. A dub changes the audio only. Text in the picture stays in the original language, and DubSync doesn't make subtitles or transcripts. You get an MP4, not a SCORM package, and you upload it to your learning platform yourself.

Can we dub a whole training library at once, and how is it priced?

Not in one go. Each video and each language is its own project, up to 150 minutes and 1 GB per file, and there is no batch upload or API. You pay per input minute, counted again for each target language: a 10-minute module in three languages uses 30 input minutes. You see the minutes and the cost before each dub starts.
