The Gradio tool for LivePortrait has been updated with fine control over animation areas, customizable features for expressions and head poses, and relative motion options that protect privacy. It supports neutral lip expressions, automatically saves, and displays suitable output formats to enhance user convenience. Its core advantage lies in expression transfer technology, which can accurately replicate expressions and dynamics onto different characters or pets, adapting to various creative needs, including facial control for static images and videos, providing users with unprecedented creative freedom.
