The run, end to end
One upload. Every language, in the speaker's own voice.
Transcription, translation, voice, lip-sync and subtitles are one orchestrated job — not five tools and a handoff between each.

Capabilities
What Video Dubbing does
Instant voice cloning
Clone a speaker from a short sample and reuse that voice across every language, so one brand voice carries into every market you ship to.
Natural lip-sync
Mouth movement is re-aligned to the dubbed audio, so translated dialogue reads as native rather than overdubbed.
Speaker diarization
Multi-speaker footage is split automatically, each voice mapped to its own target voice. Panels, interviews, and podcasts dub without manual tagging.
Subtitles and captions
Export SRT and VTT, or burn in from a library of animated subtitle styles. Fonts, colours, and safe areas follow your brand kit.
Human-in-the-loop review
A workflow gate parks the run until a reviewer approves the transcript or the speaker-to-voice mapping — translation keeps processing in parallel.
What comes out
One recording, every language, one voice
Why it matters
Dubbing pays for itself. Then it has to sound right.
The case for dubbing
Why dub your video at all
The footage already exists. Every language you add is marginal cost against a production you have already paid for.
Reach the audience you already sell to
Most people will not finish a video in a language they did not choose. Dubbing turns one production into an asset that works in every market on your revenue map, without a second shoot.
Accessibility stops being a project
Transcripts and subtitles make the same video usable for deaf and hard-of-hearing viewers, watchable on mute, and indexable by search — from the same run that produced the dub.
Training that actually lands
Comprehension and completion rise sharply when a course speaks the learner's first language. For L&D, compliance and enablement, that is the difference between content shipped and content understood.
Cheaper than the alternative, by an order of magnitude
The alternative is a studio, a booking, a voice artist and a mix — per language, per revision. Dubbing collapses that into one job you can re-run when the script changes.
The question is not whether to dub. It is whether the dub sounds like your brand or like a machine reading a script.
Why Vitra.ai
Why Vitra dubs it best
Anyone can put a synthetic voice over a video. Keeping the speaker, the emotion and the review trail is the hard part.
The original speaker, in every language
Clone the voice from a short sample and the same person presents in all 75+ languages. Brand voice survives localization instead of being replaced by a stock read.
Emotion detected, then recreated
The source delivery is analysed and rebuilt in the target language, so an urgent line stays urgent. Most tools flatten every sentence to the same neutral read — which is exactly what makes dubbing sound dubbed.
An editor built for linguists
Re-translate a line, re-speak it, retime a cue, restyle a subtitle — each on its own, without re-running the job. Speaker diarization and lip-sync are part of the same pass, not separate products.
Review is in the run, not after it
A linguist approval gate parks the job until a named person signs off, while every other language keeps processing. Corrections write back to VitraTM, so the next video starts from approved wording.
It is a step, not a destination
Dubbing is a node in a VitraFlow run. A finished cut can go straight to subtitling, quality control, personalization and publishing without anyone downloading a file.

How it works
Four steps, one orchestrated run
Every stage runs on the same platform, so nothing is exported, re-uploaded, or handed between tools.
- 01
Upload or connect
Drop a file, paste a URL, or push a job through the API. Bulk and folder-level ingestion is supported for back catalogues.
- 02
Transcribe and translate
Timestamped transcripts are generated, then translated through VitraTM — exact and fuzzy matches are reused before any model is called.
- 03
Voice, lip-sync, subtitles
Choose a native voice or clone the original speaker. Lip-sync and subtitle styling are applied in the same run.
- 04
Review and export
Edit transcripts and voiceovers in the editor, route to a proofreader if needed, then export up to 4K with subtitles embedded or separate.

FAQ
Questions people ask
How many languages does Vitra Universe dub into?
Universe dubs into 75+ languages, covering 178 language and regional variants, with over 12,000 voices available across them. Low-resource and Indic languages that most vendors do not cover are supported through Vitra's own voice models.
Can I keep the original speaker's voice?
Yes. Instant voice cloning creates a reusable replica from a short audio sample, then generates every target language in that voice — so a founder or presenter sounds like themselves in all of them.
Does Vitra handle videos with multiple speakers?
Yes. Speaker diarization detects each speaker, separates their lines, and maps each to a distinct target voice. You can review and correct the mapping before dubbing continues.
Can a human linguist review the translation before it ships?
Yes — review is native to the workflow, not bolted on. A run can pause at a WAIT gate until a reviewer approves, with configurable statuses (unverified, verified, approved) and separate linguist, proofreader, project-manager, and viewer roles.
What formats can I export?
Video up to 4K in MP4 and MOV, subtitles as SRT or VTT, and burned-in subtitles in any of the built-in animated styles. Exports can also be pushed straight to your own storage bucket.
