Strengths
Kling is known for coherent human and object motion — limbs, cloth, and camera moves that hold together across the shot.
Thirteen duration options let you match a shot to the edit instead of cutting a fixed-length clip down.
Generate matching audio with the clip in the same request when you need sound.
Pin the opening and closing frame with uploaded images and let the model interpolate the motion between them.
