Sync Labs
Developer-first lip sync API: mouth re-animation at reference quality.
About
Sync Labs (marketed as Sync) is a developer-oriented lip sync company founded by the researchers behind the Wav2Lip paper. Instead of selling a full creative studio, it sells lip sync as an API primitive: send a video plus an audio track and get back the same video with the mouth re-animated to match. Its model family (lipsync-2, lipsync-2-pro, sync-3) targets the sharpest quality tier, with sync-3 reading the whole scene for side profiles, multi-speaker frames, and low light, and the company ships API, SDKs, and Adobe Premiere and DaVinci Resolve plugins.
Pricing is pay-per-second of output (roughly $0.08/sec on the sync-2.0 tier) on top of plans from $5/month Hobbyist to $249/month Scale, plus a small watermarked free tier. Honest caveats: there is no bundled avatar, translation, or voice cloning, so buyers assemble the rest of the pipeline themselves; it is a model purchase, not a finished product.
