Kling Face Recognition API
kling-identify-faceKling Face Recognition detects faces in a video — pass a videoUrl or videoId and it returns a sessionId plus a list of faceIds. Those IDs feed Kling Lip-Sync Video: it's the first step of the lip-sync flow, letting you target exactly which face to sync in a multi-person clip before aligning audio to that face.
Kling lip-sync is a 3-step flow — run them in order; intermediate values carry forward automatically.
Step 1 · Face Recognition
Upload or paste a public video URL; recognition returns sessionId + faceId.
Step 2 · Prepare Audio
Step 3 · Generate Lip-Sync Video
Trimmed audio must be ≥2s; the insert window must overlap the face window by ≥2s.
Face Detection
Auto-detect all faces in a video
Session-based
Returns sessionId + faceId for lip-sync
Video Input
Accepts videoUrl or videoId
