sync. is a lip-sync and visual dubbing API that alters mouth movements to match new audio across languages. It is API-first with usage priced per second on top of a monthly subscription (from $5/month plus $0.05/sec).

Profile

sync. is an API-first lip-sync and visual dubbing platform built by Sync Labs that re-times mouth movements in existing video footage to match new audio, so a talking-head clip can be re-dubbed or translated into another language without reshooting. It ships no consumer video editor of its own — it is meant to be embedded into other products via a RESTful API and SDKs, priced on a monthly subscription plus per-second usage.

Who builds it

sync. is developed by Sync Labs, a company focused specifically on lip-sync and dubbing infrastructure rather than general-purpose video generation. Instead of competing on avatars or text-to-video, the product's whole surface area is one job: take a video and a new audio track (translated speech, a different voice, or edited dialogue) and output a version where the lips match the new audio. That narrow focus is why it is consumed as an API rather than a studio-style web app.

Core features

  • Lip-sync via a single API call, described on the pricing page as the ability to "lipsync any content w/ one api," for integrating dubbing into an existing video pipeline.
  • The lipsync-2-pro model, sync.'s current engine for matching mouth movement to new audio.
  • Dubbing into 29 languages, letting a source video's audio be swapped and re-synced across a fixed set of target languages.
  • RESTful API and SDKs, with a Batch API available on the top Scale tier for processing many videos at once.
  • Per-tier video-length caps, rising from 1 minute on Hobbyist up to 30 minutes on Scale.
  • Whitelabel / watermark removal, offered from the Creator tier upward, implying entry-level output can carry a sync. mark.

Pricing

sync. does not use a flat per-video price or a pure credit pack; it combines a fixed monthly subscription with per-second usage billing:

  • Hobbyist: $5/month + $0.05/sec, videos up to 1 minute.
  • Creator: $19/month + $0.05/sec, videos up to 5 minutes, watermark removed.
  • Growth: $49/month + $0.0475/sec, videos up to 10 minutes.
  • Scale: $249/month + $0.04/sec, videos up to 30 minutes, plus Batch API access.
  • Enterprise: custom pricing via sales.

The per-second rate drops slightly as the subscription tier rises, so heavy usage is cheaper on Growth or Scale than on Hobbyist. There is no permanent free plan, though the site invites visitors to "try sync for free" in a limited capacity.

Who it's for

sync. targets developers and video platforms that need lip-sync as a backend capability rather than a manual editing tool: localization and dubbing services translating creator or corporate video into multiple languages, ad-tech platforms swapping voiceovers across markets, and SaaS products (e-learning, HR, marketing tools) that want to embed automatic re-dubbing into their own workflow via API instead of sending users to a separate editor.

Frequently asked questions

What does sync. cost?

sync. combines a fixed monthly subscription with per-second usage billing rather than a flat per-video price. Plans run from Hobbyist at $5/month plus $0.05/sec, through Creator at $19/month plus $0.05/sec and Growth at $49/month plus $0.0475/sec, up to Scale at $249/month plus $0.04/sec; Enterprise pricing is custom. The per-second rate decreases slightly on higher tiers, so cost scales with both the plan and how many seconds of video you process.

Is sync. free, and does the entry plan add a watermark?

There is no permanent free plan; the cheapest paid tier is Hobbyist at $5/month plus $0.05/sec, alongside a limited free trial invitation on the pricing page. The Creator tier and above explicitly list watermark removal (via a whitelabel feature) as a feature, which implies Hobbyist-tier output is not watermark-free by default — confirm the current wording on the pricing page before relying on it.

What is the maximum video length in sync., and does it state a max resolution?

Maximum video length scales by plan: 1 minute on Hobbyist, 5 minutes on Creator, 10 minutes on Growth, and 30 minutes on Scale. The pricing page does not publish a maximum output resolution figure, so treat resolution as unspecified until confirmed directly with sync.'s documentation.

Can I use sync. output commercially?

sync.'s pricing page does not spell out commercial usage rights in plain language, so this should be confirmed in sync.'s terms of service before commercial deployment, particularly for dubbing content that features real people's likenesses and voices. The API-first, subscription-plus-usage model is built for business integrations, but licensing specifics aren't stated on the page reviewed.

Does sync. have an API?

Yes — sync. is API-first: every paid tier from Hobbyist upward includes "RESTful API and SDKs for seamless integration," and the Scale plan adds a Batch API for processing videos at volume. There is no separate no-code editor; the API is the primary product surface.

sync. vs HeyGen — which lip-sync/dubbing tool should I pick?

sync. is a narrow, API-first lip-sync engine (from $5/month plus per-second usage) built for teams embedding dubbing into their own product, while HeyGen is a broader AI video platform whose Video Translation feature dubs and lip-syncs into 175+ languages as part of an avatar-video suite starting at $29/month with a free tier. Pick sync. if you want a lean API to integrate directly into a pipeline; pick HeyGen if you also want avatars, an in-app editor, and a free plan to start from.
