AI lip sync generation
Generate matched lip movement from video and audio input, with multiple models tuned for different quality and speed tradeoffs.
Overview
Sync Labs is an AI video lip sync and visual dubbing platform for generating new speech-matched video from existing footage. It is positioned for films, ads, content localization, and other workflows where the speaker's mouth movements need to match new audio.
The product can be used through a web studio or via API and official SDKs, and the site presents several models with different tradeoffs, including sync-3, lipsync-2-pro, and react-1. The docs describe the system as suitable for production integration, batch processing, webhooks, and dubbing workflows that combine video with translated audio.
Core features
Studio, API, and SDK access
Work in the browser or through the API, with official Python and TypeScript SDKs for production integration.
Spatially aware sync-3 model
Use sync-3 for more demanding shots, including scenes with multiple faces, sharp angle changes, low light, and fast camera movement.
Studio-grade editing model
Use lipsync-2-pro for studio-grade editing with 4K support and preservation of facial details such as teeth, freckles, and beards.
Video verification
Verify whether a video was modified with Sync Labs technology using its proprietary watermarking verification flow.
Workflow scaling
Scale processing with batch workflows and higher-tier features such as more concurrency, batch API access, and team workspaces.
Common use cases
Video dubbing and localization
Localize films, social clips, and other finished videos by matching new translated audio to the original speaker's face and mouth movements.
Marketing and ad production
Generate polished lip sync for promotional content where visual consistency and turnaround matter, including ads and branded videos.
Product and workflow integration
Use the browser studio or API to add lipsync into internal tools, SaaS products, or automated content pipelines.
Complex scene generation
Handle more demanding scenes such as fast camera moves, low light, multiple faces, or side angles where context and detail preservation matter.
Model evaluation and testing
Compare models and outputs directly in Studio before rolling a chosen model into production use.
