You can use voice cloning to auto-translate in a select number of languages within LipDub AI.
LipDub AI modifies on-screen performances to perfectly match target audio tracks.
It begins by analyzing who’s on screen and when they speak, intelligently grouping and labeling identities across all uploaded training footage.
From there, LipDub AI learns how each identity articulates while speaking, tracking every detail—lips, lower face, facial hair, and even how the neck and shirt collar move. This generative model aims to recreate the most realistic version of the original performance.
Once trained, LipDub AI flawlessly syncs the source performance to the new audio, delivering a result that looks and feels completely real.
AI lip sync is typically associated with translation and localization, but many LipDub AI customers find tremendous value in using it for custom avatars, dialogue replacement and personalization.
More than just swapping languages, LipDub AI allows users to easily modify video dialogue, whether it's changing a few words or replacing the entire script.
Customers are especially excited about this use case because the realism we deliver, combined with ease of use, gives them unprecedented control over their video content while significantly reducing production time and cost.
The platform currently supports professional resolution MOV or MP4 files, up to 4K resolution, with both ungraded and graded footage.Supported colorspaces include sRGB and Rec709. For best results, avoid manipulated footage, such as text overlays on faces or fade-in transitions.
LipDub AI is the only technology of its kind that supports all languages. While auto-translation within the platform is available for select languages, users can upload their own audio in any language, dialect, or accent, and LipDub AI will perfectly lip sync to match.
