Sync Labs
AI lip sync and visual dubbing with 4K ProRes output from Studio, API, Premiere Pro, Resolve, or ComfyUI
If lip sync has to pass a studio review, Sync Labs is the one we'd put in the pipeline. Plugins for Premiere Pro and DaVinci Resolve mean results land back on the timeline instead of a downloads folder, and the September 30, 2026 changelog shows Studio now displays generation ETAs, keeps jobs running after you close the tab, and lets you re-request a download of a finished API output by ID without paying for a second generation. The catch is arithmetic: per-second billing starts at $5/mo plus $0.05/sec on Hobbyist and only drops to $0.04/sec on Scale at $249/mo, so budget the shot list before you commit — or compare against a one-off web lip sync app if your footage is simple.

Skip Sync Labs if your footage is clean, short, and single-language and a free or open-source lip sync tool covers it, or if you need live real-time sync rather than a render-and-review pipeline.
Usage is billed per second on top of the subscription — $0.05/sec on Hobbyist and Creator means a 10-minute clip runs about $30 before your monthly fee.
Sync Labs fits teams with a defined shot list and a real per-second budget. Hobbyist at $5/mo plus $0.05/sec covers weekend experiments; Scale at $249/mo plus $0.04/sec with a 20% usage discount and Batch API is where a localization studio breaks even against one-off web lip sync apps. Below Scale, per-second billing on 30-minute content gets expensive fast, and the free tier is capped at 3 generations/month of 20 seconds each.

About Sync Labs
Sync Labs (sync.so) is an AI lip sync and visual dubbing platform from Synchronicity Labs, aimed at post-production teams, localization studios, and developers who need a synced clip that survives a review gate. The headline model is sync-3, documented as 4K native and built for messy footage: objects blocking the face, multiple faces in one frame, multiple camera angles, low light, fast camera movement, and rapid dialogue. Older models — lipsync-1.9, lipsync-2, lipsync-2-pro, and react-1 — stay available when speed or cost matters more than fidelity; the docs put pricing across the model range from $0.02/sec on lipsync-1.9 to $0.133/sec on sync-3 at 25 fps. As of the August 31, 2026 changelog, built-in dubbing supports 92 languages and returns lossless audio for the final dub, with automatic speaker detection. It ships as a pipeline stack, not one app. You can work in the browser through Lipsync Studio, whose workflow dashboard routes you into lip sync, translate-and-dub, image-to-video, the sync. assistant, or the timeline editor. Developers call the REST API with official Python and TypeScript SDKs and receive webhook status notifications instead of polling. Editors run the Adobe Premiere Pro or DaVinci Resolve plugin, and custom pipelines use the ComfyUI node. Batch processing handles up to 500 generations per batch on Scale and above. Image-to-video on sync-3 turns a single still plus an audio track into a talking video when there is no source footage. Sync also ships a verification tool that checks whether a video was modified using its proprietary watermarking technology. Pricing is usage-based on top of a subscription: you pay per second of video generated, and higher tiers discount that rate by up to 20%. Plans gate video length, concurrency, voice-clone slots, batch API access, and team seats. A per-second model rewards teams who know their shot list and punishes open-ended experimentation.
Behind the Verdict
Sync Labs wins on the parts of lip sync that are actually hard in professional post. The homepage lists the failure modes sync-3 is built for — objects blocking the face, multiple faces, multiple camera angles, low light, fast camera movement, rapid dialogue — and the docs back that with a 4K native face resolution for sync-3 versus 512×512 on lipsync-2 and lipsync-2-pro. That distinction matters: if you're finishing in 4K, you don't want a generation that needs an upscale pass before it hits the timeline. The integration story is the real differentiator. Premiere Pro and DaVinci Resolve plugins put the result back in the edit, the ComfyUI node covers custom pipelines, and the REST API with Python 3.8+ and TypeScript/Node.js 18+ SDKs plus webhooks means you can build lip sync into a product without polling loops. The August 31, 2026 changelog expanded built-in dubbing to 92 languages with automatic speaker detection and lossless audio for the final dub, and the September 30, 2026 release fixed real workflow friction: ElevenLabs-connected accounts now load the full voice library including workspace-shared voices, API keys can create and check transcription jobs, and completed outputs can be re-downloaded by ID. The weaknesses are cost shape and ceilings. Per-second billing is honest but unforgiving — the docs quote $0.02/sec on lipsync-1.9 up to $0.133/sec on sync-3 at 25 fps, and the plan discounts (5% on Growth, 20% on Scale) only soften that. Video length is gated by tier at 1, 5, 10, or 30 minutes, concurrency runs 1, 3, 6, or 15 jobs, and the docs tie batch processing of up to 500 generations to Scale and above. Higher-quality models are explicitly a paid unlock: the pricing page says to subscribe to unlock higher quality models and longer videos. If your footage is simple and your budget is zero, a free or open-source lip sync tool covers the job. If your job is hard footage, a multi-language dub, or an automated pipeline, this is the tier of tool you'd otherwise assemble yourself.

Real-world workflow fit
Concrete scenarios for the personas Sync Labs actually fits — and what changes day-one when you adopt it.
You get a new Japanese audio track for a 12-minute interview with the subject partly turned away from camera. You open the Premiere Pro plugin, pick sync-3 for the 4K native output, and submit the clip.
Outcome: Studio shows an estimated time remaining, the job keeps running after you close the tab, and the finished clip lands back on your timeline without a transcode pass.
A client wants one training video in six languages. You run the built-in dubbing flow in the Studio timeline editor, which auto-detects speakers and returns lossless audio for the final dub.
Outcome: Dubs across the 92 supported languages come back as synced video, and on a Scale plan the 20% usage discount and 15-job concurrency keep the queue moving.
You install the TypeScript SDK, submit a generation with your API key, and subscribe to a webhook instead of polling for status.
Outcome: Finished outputs can be re-downloaded by ID later without paying for a second generation, which keeps your retry logic cheap.
Use Cases
- Localize an e-learning course by translating and lip syncing the instructor's lectures into 92 supported languages while keeping the face natural.
- Automate ADR in post-production by matching new audio to an actor's lip movements on occluded or fast-moving footage.
- Dub a YouTube video into dozens of languages with visual dubbing that preserves the speaker's lip movements.
- Generate personalized video messages at scale by swapping the spoken name in each generated clip.
- Adapt a single marketing recording into region-specific versions with culturally relevant language.
- Animate a still image into a talking video for spokespeople, archives, or historical photos when no source footage exists.
- Integrate lip sync into a game engine or app to animate character dialogue from text-to-speech output.
- Run a 500-item batch localization job through the Batch API on a Scale plan.
Models Under the Hood
as of 2026-10-16
Limitations
- Usage is priced per second of video generated plus a monthly subscription, so total spend depends on runtime, model choice, and plan tier rather than the subscription alone; the docs quote $0.02/sec on lipsync-1.9 up to $0.133/sec on sync-3 at 25 fps.
- Plan tiers cap video length (1 min Hobbyist, 5 min Creator, 10 min Growth, 30 min Scale), concurrency (1/3/6/15 jobs), and voice-clone slots (3/5/15/50).
- The pricing page states you must subscribe to unlock higher quality models and generate longer videos.
- Batch API is listed only on Scale, and premium perfection work routes to the sales team rather than a self-serve tier.
- Concurrency caps also constrain shops that need many parallel jobs.

Switching to or from Sync Labs
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a single-purpose web lip sync app: export your source clips, sign up for Hobbyist, and rerun the shots through Lipsync Studio Lite with the same audio.
- →From ComfyUI-only open-source nodes: keep the graph, swap the lip sync node for Sync's ComfyUI node and supply an API key.
- →From manual ADR in Premiere Pro or Resolve: install the plugin so generated takes land directly on the timeline instead of a downloads folder.
- ↗To a free open-source lip sync tool: keep the same source video and audio, re-render through the local model, and accept lower face resolution than sync-3's 4K.
- ↗To a single-purpose web lip sync app: export project sources and rebuild the shot list, losing plugin-on-timeline delivery and the batch API.
