What is Sync Labs?

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.

What can Sync Labs do?

AI lip-sync generation

Generate matched lip movement from video and audio input, with multiple models tuned for different quality and speed tradeoffs.

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.

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 lip-sync to 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.

Frequently Asked Questions

How do I use Sync Labs in practice?

The pricing page shows a free plan and paid tiers, and the docs describe a free trial with 3 generations per month and a 20-second maximum per generation without a credit card.

Which model should I choose?

The platform supports multiple models with different quality and speed tradeoffs, including sync-3, lipsync-2-pro, and react-1. The docs note that model choice depends on the use case and that sync-3 is native 4K while lipsync-2-pro is 4K-capable on its page.

What kinds of content can it handle?

The docs describe visual dubbing and content localization workflows where you supply video and matching audio, including translated audio in another language. The homepage also says the system works across films, ads, podcasts, games, and animations.

What changes as I move up plans?

The pricing page lists plan-based limits such as video length, concurrent jobs, voice cloning allowances, and team seats. Higher tiers add longer outputs, more concurrency, batch API access, and larger usage discounts.
