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.
