Sync Lipsync is an AI-driven model that performs precise lip synchronization, aligning mouth movements in any given video or image-to-video sequence with new audio. It enables creators to produce realistic talking avatars and natural video dubbing without manual animation work.
Sync Lipsync can take any input speech track and sync it to an existing speaker’s video (audio-to-video), preserving their unique lip movement style. This helps localization teams create polished multilingual or dubbed content with accurate mouth motions.
Unlike simpler image-to-video generators, Sync Lipsync uses a zero-shot style-preserving model to reproduce natural lip motion and facial detail. It supports multiple formats, high-resolution output, and automatic detection of active speakers in complex scenes.
While Sync Lipsync offers free trial credits for new users, full access to its image-to-video and audio-to-video capabilities requires spending platform credits on Runcomfy’s AI playground, depending on the chosen plan and video resolution.
Sync Lipsync is designed for content creators, filmmakers, animators, and localization professionals who want high-fidelity lip synchronization in their image-to-video and audio-to-video workflows, from dubbing to character re-animation.
The base Sync Lipsync model delivers realistic results for most cases, but the Lipsync-2-Pro version enhances image-to-video fidelity through diffusion-based super resolution, producing sharper teeth, beards, and fine face details.
Sync Lipsync is available on the Runcomfy website’s AI playground, accessible through desktop or mobile browsers. Users must log in to access image-to-video tools, and can manage projects through web-based interfaces.
Yes. Sync Lipsync can operate on either still portraits (for image-to-video applications) or pre-recorded video clips (for audio-to-video dubbing), making it versatile for both animated avatars and dialogue replacement.
Although Sync Lipsync provides highly realistic lip synchronization, image-to-video outputs may vary depending on lighting, occlusion, or head pose angles. Extremely obstructed faces or low-resolution source media may reduce fidelity.
