sync. labs

What is sync. labs?

sync. labs is a lip-sync service that edits the mouth movements in existing video so they match new audio. It offers the lipsync-2, lipsync-2-pro and sync-3 models, and its pages say the technology works on films, podcasts, games and animation. Teams use it through a web studio or a REST API with SDKs, and can add text-to-speech with custom voices, dubbing into 29 languages and batch jobs. Pricing combines a monthly plan with per-second usage: Hobbyist at $5/month, Creator at $19/month, Growth at $49/month and Scale at $249/month, with usage from $0.04 to $0.05 per second at the entry model and discounts of 5% and 20% on higher tiers. A free account gets 3 generations a month, each up to 20 seconds, without a credit card. Enterprise terms are available through the sales team.
