Lab ModeUpdated Mar 9, 2026ai lip sync video

Lip Sync That Looks Natural, Not Uncanny

AI-generated characters that speak need mouths that move convincingly. Poor lip sync breaks immersion instantly and makes content look amateurish. Seedance Lab mode provides precise control over speech-to-motion mapping, producing lip sync that matches audio cadence naturally — for UGC-style content, narrator-driven explainers, and character-based series where believable speech is non-negotiable.

Audience

UGC creators, content marketers, explainer video producers, and localization teams.

Use Case

Produce character-driven video content with believable lip sync for marketing, education, and entertainment applications.
