Learn how global brands localize video campaigns into 20 languages: one master, a glossary, two 10-language translation jobs and native review. Try it free.
TL;DR: Translate one approved master in HeyGen's Video Translation as two 10-language jobs, because it re-voices the speaker in their own voice with lip sync, and Precision mode handles cuts and side angles at 10 credits per minute.
- A dubbing agency is still the better call for broadcast spots where a director shapes every line read.
- Subtitles alone win on cost in markets where viewers expect to read along.
- ElevenLabs Dubbing is a strong pick when the voice track matters more than the face on screen.
- Rask AI suits teams localizing a large back catalog of existing videos.
Twenty languages at a mid-range dubbing rate of $20 to $40 per finished minute puts one 60-second spot at $400 to $800 in voice work alone, before translation, mixing and review (VerboLabs 2026 rate guide). The same spot through Precision-mode video translation uses 200 credits for all 20 versions, about a third of one Creator month.
The cost gap is the easy part. The harder part is what breaks on the way: on-screen text, sound effects, and ad lengths that drift. This guide shows how global brands can localize video campaigns into 20 languages, step by step, including the three layers most guides leave out.
How to Localize a Video Campaign Into 20 Languages with HeyGen
1. Lock the master and build a glossary
Translation starts from one approved master: a single spoken language, a final edit, and no captions burned into the picture.
Next, open Brand Glossary and mark every product name, tagline and legal term with Don't Translate; larger lists can be uploaded as a CSV. This takes about 30 minutes for a typical campaign and prevents the most common review comment: a translated brand name.
2. Upload the master and pick your first 10 languages
Open Video Translation and upload the file (MP4, MOV or WEBM, up to 5 GB) or paste a YouTube or Google Drive link; Vimeo links aren't supported. You can select up to 10 target languages per job, so 20 languages means two jobs from the same master, and the video translator keeps the original speaker's voice in both.
For each language, choose Base to keep the speaker's own accent, or a localized variant for a native regional accent, which suits most ad markets.
3. Pick the engine and the advanced settings
Choose Precision (10 credits per minute) if your ad has cuts, side profiles, or a hand near the face; Speed (6 credits per minute) suits one speaker facing the camera within about 45 degrees.
Under Advanced, turn on Create a Collection so all 20 versions sit together, and Enable Captions to get a captioned and a clean version of each, plus an SRT file. Read the section below on Dynamic Duration before you decide on fixed-length paid slots.
4. Pilot one language before you run the rest
HeyGen's own guidance is to translate one language first and confirm quality before running the full set. Send the pilot to your strictest regional reviewer, then fix glossary terms before the big run.
On Pro and above, Proofread lets a linguist edit the translated script word by word before the final render, which is the fix when reviewers call a translation too literal.
5. Run both jobs and route each version to a native reviewer
Launch the remaining nine languages, then the second job of 10. You get an email when each translation finishes, so you don't need to keep the page open.
Give every reviewer the same four-point checklist: claims, tone, names, and lip sync on close-ups. For markets where the presenter is mostly off-screen, audio-only AI dubbing at 4 credits per minute is the cheaper option.
What Video Translation Won't Touch in an Ad
Most localization guides stop at the voice track. Ads carry three more layers, and the help center is direct about each one.
Length is the layer that catches ad teams out. One localization vendor estimates that German and French scripts often run 20 to 30% longer than English, and a broadcast slot doesn't stretch. Write the source script about 10% short of the slot, and the translated versions land inside it.
Music behaves differently from effects: it stays in the translation unless you choose Remove Background Sound. For ads with a licensed track, remove it, then lay the clean music stem back under each language so every market hears the same mix.
What You Need Before You Start
- A single-language master. Videos with more than one spoken language fail or produce an inaccurate transcript. Good enough: the final cut already approved in your home market.
- A textless export and separate stems. Ask your editor for a version without supers, plus music and SFX on separate tracks. Good enough: a textless export alone, if the agency can't supply stems.
- A glossary list. Brand names, product names, legal terms and any phrase that must stay in English. Twenty terms is enough to start.
- One native reviewer per market. A regional marketer or local partner works; they review, they don't rewrite.
- The right plan. Creator and Pro cap each video at 30 minutes, and Proofread starts on Pro.
What Results to Expect
Here's what teams running this workflow report.
Trivago localized its TV ads across 30 markets with HeyGen, cut post-production time in half and saved three to four months. The team wanted one person to stay the brand's face in every language instead of hunting for a single actor who could cover them all.
Workday translates videos into 10 to 15 languages per project and reports producing a video in a day rather than months, with a 100% increase in capacity without adding headcount. Its linguists proofread inside the platform, and an uploaded term base keeps approved product terms intact.
Würth Group cut translation costs by 80% and production time in half while producing video in 10+ languages for training and global communication. The full trivago story shows how the team handled a fixed broadcast deadline on its first project.
How the Methods Compare
For presenter-led ads, translation with lip sync is the only method that keeps the same face, the same voice and the same cut in every market at a cost that doesn't multiply with each language.
Other Ways to Localize Video Campaigns
Hire a dubbing agency
A dubbing agency casts native voice actors, records in a studio, and times each line to picture. For a hero broadcast spot with a director in the booth, it's still the benchmark. VerboLabs' 2026 rate guide puts mid-range professional dubbing at $20 to $40 per minute and high-end studio work at $50 or more.
Pros:
- Human performances shaped by a director
- Native speakers catch cultural nuance in the read
- Broadcast audio standards
- Full control over casting per market
Cons:
- Every script change means rebooking talent in all 20 languages
- A different actor per market means the presenter no longer sounds like themselves
Ship subtitles only
Subtitles translate the words on screen and leave the original audio untouched. In markets with a strong subtitle culture, or for ads that work with the sound off, they're a fast, cheap layer.
Pros:
- Lowest cost per language
- Fast turnaround
- Easy to edit after launch
- Helps accessibility in every market
Cons:
- The presenter still speaks the source language, which weakens a talking-head ad
- In a 15-second spot, reading competes with the visuals
Use ElevenLabs Dubbing
ElevenLabs built its reputation on voice quality, and its dubbing tool sits inside a large voice platform with cloning and editing tools. It's a strong fit for narrated or voiceover-led ads where the speaker's mouth is rarely on screen.
Pros:
- Highly natural voices
- Broad voice ecosystem and cloning
- Editing tools for the dubbed track
- Strong brand with audio teams
Cons:
- Built voice-first; lip-sync support varies by source, so mouths can drift on close-up talking-head ads
- Video finishing (supers, captions, cut) happens in another tool
Use Rask AI
Rask AI is a localization platform aimed at translating existing videos at volume, with multi-speaker detection and an API on higher tiers.
Pros:
- Built for high-volume localization
- Detects multiple speakers
- API for batch workflows
- SRT import and export
Cons:
- According to 2026 pricing reviews, lip-synced minutes draw down plan allowances faster than audio-only minutes
- Monthly minute caps get used up quickly when every video ships in 20 languages
Frequently Asked Questions
Do we need lip sync in every market?
No. Workday deliberately avoids lip sync as part of its ethical AI approach and still localizes into 10 to 15 languages per project.
Lip sync matters most on close-up talking-head ads; for B-roll-heavy spots, the Audio Only engine at 4 credits per minute is enough. When you do need it, AI lip sync runs inside the Speed and Precision engines.
Can we translate into all 20 languages in one job?
Not in one job: the limit is 10 target languages per job. Run two jobs from the same master and turn on Create a Collection in each, so all 20 versions are grouped on your Projects page.
Why does the translation sound too literal?
Reviewers often describe AI translation as "surprisingly literal," and the help center is clear that it can't guarantee 100% accuracy. The fix is a layered one: a glossary for terms, Proofread (Pro and above) for wording, and a native reviewer for tone. Fixing the script in Proofread costs no extra credits if you go on to translate.
Will the presenter keep their own voice?
Yes. Both Base and localized variants use the original speaker's voice for voice similarity; the choice only changes the accent. Pick Base when the speaker's identity matters, and a localized variant when you want the ad to sound native to the market.
How do we handle markets that share a language?
Many languages offer regional variants, and the default is the most common one (American English for English, for example). For Spain and Mexico, or Brazil and Portugal, run separate variants and give each its own reviewer.
Can translated versions go into our LMS or a password-protected link?
Yes. Share links can be password protected, and translated videos export as SCORM packages on Business and Enterprise plans for teams that reuse campaign content in partner or sales training.
The fastest way to localize a video campaign into 20 languages is one approved master, a glossary, two 10-language Precision jobs, and a native reviewer per market. You can test a single language on the free plan, and Creator ($29 a month, 600 credits) covers 20 versions of a 60-second spot with room to spare.
