Overview
Kling Video V1 Pro AI Avatar is an AI model that creates realistic talking avatar videos by synchronizing facial movements and lip movements with audio content. The model takes a static portrait image and an audio file, then generates a video where the person in the image appears to be speaking the provided audio with natural lip-sync, facial expressions, and head movements. The generated videos maintain the original image quality while adding lifelike animation based on the audio input.
