## 概要

sync. labs (formerly sync.so) is an AI lip sync and visual dubbing platform that retimes an actor's mouth and facial performance to any audio track. It pairs a browser-based Studio with an AI Assistant, NLE plugins for Premiere Pro and DaVinci Resolve, a ComfyUI node and a REST API, so teams can localize a performance into 29 languages while keeping the original delivery intact.

## 料金とプラン

Usage-based pricing on top of a subscription. Verified plans from the pricing page: Hobbyist $5/mo (1 min videos, 3 concurrent jobs, 3 voice clones), Creator $19/mo (5 min, 10 concurrent, 5 voice clones, active speaker detection, no watermark), Growth $49/mo (10 min, 20 concurrent, 15 voice clones, 5% usage discount, 3 seats), Scale $249/mo (30 min, 50 concurrent, 50 voice clones, 20% usage discount, 5 seats, batch API). Generation is metered per frame — for example lipsync-2 at $0.002/frame (~$0.05 per second at 25 FPS) up to sync-3 at $0.00533/frame (~$0.133 per second) — while dubbing is about $0.10 per second of audio ($6/min) and text-to-speech about $0.004 per second ($0.24/min) on the entry tiers. Enterprise pricing is by contact for customization, dedicated support and negotiated rates.

## 主な機能と特長

- **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.
- **Pipeline integrations and API:** Premiere Pro plugin, DaVinci Resolve plugin, ComfyUI node, REST API and SDKs, with a Batch API for launching hundreds of videos in one call.
- **Watermark verification:** Proprietary watermarking lets you upload a video and check whether it was modified using sync.'s technology, supporting provenance and rights checks.

## 主なユースケース

- **Visual dubbing for localization (Film and TV post-production):** Localize a performance into another language while preserving acting nuance, then verify delivery frame by frame in the timeline editor before final conform.
- **Multi-market campaign variants (Advertising and brand teams):** Shoot the spot once with one actor and produce synced versions across languages using cloned voices, cutting the cost of separate localized shoots.
- **Dialogue fixes and clip repurposing (Content creators and podcasters):** Repair blown takes, change a line, or dub a clip for a new audience with the Lite assistant and no editor experience.
- **Lip sync at scale via API (Developers and product teams):** Automate localization or avatar workflows with REST endpoints and SDKs, using the Batch API and concurrency limits sized to your plan.

## 強み

- 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

## 制約・デメリット

- 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

## よくある質問

### What is sync. labs and how is it different from other lip sync tools?
sync. labs is an AI lip sync and visual dubbing platform built for production conditions rather than clean studio footage. It explicitly targets side faces, obscure angles, low light, multiple faces and fast camera movement, and it ships as a web Studio, an AI Assistant, NLE plugins and an API rather than a single app.

### How much does sync. labs cost?
The published plans are Hobbyist at $5/month, Creator at $19/month, Growth at $49/month and Scale at $249/month, plus Enterprise on request. On top of the plan fee, generation is billed per frame of video (for example about $0.002 per frame for lipsync-2 and $0.00533 for sync-3), with dubbing billed around $0.10 per second of audio and text-to-speech around $0.004 per second on lower tiers.

### Can I use it through an API instead of the web app?
Yes. sync. offers a RESTful API and SDKs, and every listed plan includes API access. The Scale tier adds a Batch API for launching hundreds of videos with a single call, which suits localization pipelines and product integrations.

### How many languages can I dub into?
The pricing page states that dubbing covers 29 different languages. Because lip sync regenerates the mouth performance rather than just swapping audio, the visual result matches the new language.

### Do I need my own text-to-speech provider?
You can use sync.'s text-to-speech and custom voice features, or bring your own TTS API key generation from Creator tier upward if you already rely on a specific voice provider.

### Is there a way to tell if a video was made with sync.?
Yes. sync. applies proprietary watermarking and offers a verification flow: you upload a video and it checks whether the footage was modified using their technology.
