DubMaster is the first AI dubbing platform that puts you in the director's chair β with scene context, emotional controls, and a memory that learns your style.
Original Cantonese
English Dubbed
One-shot. No memory. No craft. The translation comes out, you take it or leave it β and if you don't speak the language, you have no idea whether what was said was right, wrong, or the complete opposite of what was meant.
Every correction you make is a directorial decision. Every decision gets remembered. Every future film benefits. That's not a tool β that's a studio.
Martial arts dubbing β the hardest test in the industry

Get your film into any market without a dubbing studio budget.
Full studio access on every plan
Reach global audiences without losing what makes your content yours.
Start free β no card required
Dub across your entire catalog without growing the headcount.
Unlimited projects, permanently kept
A workspace that remembers every decision you've ever made.
Your Rulebook compounds
DubMaster transcribes, diarizes, and translates automatically β across 50+ languages. You get a full scene breakdown before you touch a single line.
The Scene panel tells you what's happening, who's speaking, and what the line is doing dramatically β even if you don't speak the language, you'll know what the dialogue is and whether it's right. If it isn't, the changes are just a click away β your decision, your way.
Every decision goes into your Rulebook β character voices, name mappings, tone rules, translation fixes. The next film you dub starts smarter than the last one ended.
Zero-shot cloning preserves each actor's voice, accent, and delivery
emotion2vec scores every line against the original performance
Word-level timing analysis on every rendered segment
Lip-sync, emotion, timing, and translation findings β written up per segment
Tuned for Cantonese and Mandarin; Japanese, Korean, Hindi, and more
Upload and it runs β short clips finish in minutes
Timeline editor, retranslation, voice casting, and review queue
Your corrections and directorial choices persist and shape future jobs
When a line is supposed to be a dismissal and the translation reads like an invitation β you'll catch it. Because DubMaster tells you exactly what's happening in the scene. The AI does the language. You do the direction.
What this moment means dramatically
Dismissal, challenge, confession, plea
Who's talking and how they talk
What the original performance felt like
Accept, Correct, or Adapt
Voice actors know the characters. Directors know the style. Writers know the idioms. That knowledge lives in people β and walks out the door when the project ends. DubMaster captures it digitally and makes it cumulative.
Every name mapping. Every character voice. Every register rule. Every translation fix. Stored globally, applied to every future job. The longer you use DubMaster, the smarter it gets β about your films, your style, your creative voice.
That's the moat. That's what no one-shot tool can replicate.
A lip sync engine regenerates the mouth region pixel-by-pixel using a generative model β predicting visemes and repainting the lower face to match, frame by frame. When it works, it's impressive. When it fails, it produces soft rectangles where a mouth used to be, identity drift, and desync on plosives. And failure is common β occlusion, rotation, low resolution, scene cuts, and complex lighting all break these engines. Most fail silently. Every failed frame still costs money.
We align in the time domain β not the pixel domain. Your original face is never touched. Every dubbed line lands at the word-level onset of the original speech, with silence trimmed to 20ms. The QC Monitor measures real audio offset in milliseconds β a feedback loop, at no extra cost.
Fast action, martial arts, high-energy scenes β where head rotation breaks face tracking, motion blur destroys the mouth region, and fast cuts leave less than a second of stable footage. A lip sync engine doesn't just underperform there; it fails on most frames, and you pay for every failed frame. DubMaster never touches the original face. Your actors stay your actors.
We offer it β powered by Sync.Labs, priced at cost plus a small platform fee. But understand what you're buying: a generative pass that repaints the mouth region. It works on frontal, well-lit, high-resolution footage and struggles on everything else. Our recommendation: align manually and score with the QC monitor first. Most directors find they don't need more.
We give you the tool to get it right. We offer the option to go further. We're honest about which one most productions actually need. An informed customer is the best customer.
