/openapi/v2/kling-lip-sync/lip-sync-video

Kling AI's lip-sync video generation model that achieves frame-level synchronization between character lip movements and audio content based on input face recognition result videos and audio. Supports real humans, 3D and 2D animated characters, processing both local audio uploads and online synthesized voiceovers. Employs audio-aligned frame interpolation strategies to ensure accurate lip shape restoration even for phonetically challenging syllables, with generation duration extendable to minute-level.
