rh-lip-sync-videoKling Lip-Sync Video does frame-level lip synchronization, aligning an audio track to the mouth movements of a character in a video — real humans, 3D and 2D animated characters — with local audio upload or online TTS and minute-level duration. The typical flow is to run Kling Face Recognition first to get a faceId, then align audio (uploaded or from Kling Lip-Sync TTS) to that face. Ideal for digital-human voiceover, dub-to-lip-sync and talking animated characters.
