sync. labs (sync.so)

Studio-grade AI lip sync, visual dubbing and voice cloning for film, ads and creator content

Advanced lip sync models

A model lineup spanning sync-3, lipsync-2-pro, lipsync-2 and react-1, handling side faces, occluded mouths, multiple faces per frame, low light and fast camera movement, up to 4K ProRes footage.

Visual dubbing in 29 languages

Keep the original performance and delivery while replacing the dialogue language, so a single shoot can serve global markets without reshooting the actor.

Text-to-speech and voice cloning

Generate the new voice track inside the platform or bring your own TTS API key; plan tiers include a set number of custom cloned voices.

Studio timeline plus AI Assistant

A frame-accurate editor for cut, trim and split work, alongside a guided assistant where you describe the change you want and it configures the generation.

Strengths & Pros

+Handles production-grade edge cases other lip sync tools struggle with: side profiles, occluded faces, multiple faces, low light and fast motion
+Multiple access paths — web Studio, AI Assistant, Premiere Pro and DaVinci Resolve plugins, ComfyUI node and full API — so it fits existing pipelines
+Very wide language coverage for dubbing (29 languages) paired with in-platform voice cloning or bring-your-own TTS
+Fine-grained, consumption-based metering means you are billed for what you actually generate rather than buying opaque credit bundles
+Rare provenance feature: watermarking and a verification flow for checking whether a video was modified
+Clear public pricing table with per-frame model rates, so usage cost can be estimated before committing

Limitations

–Costs stack up: a plan fee plus per-frame, per-second dubbing and per-second TTS charges can be hard to predict for high-volume projects
–Entry-level Hobbyist tier is limited to 1-minute videos and 3 concurrent jobs, which is tight for real production work
–Cheapest rates only unlock on the Scale plan, so heavy users on lower tiers pay noticeably more per frame
–Voice cloning quotas are plan-gated (3 to 50 voices), which can constrain multi-language casting at lower tiers
–Dubbing and lip sync are billed separately, so a fully localized video should be costed as two line items
