AI cannot generate natural human micro-expressions

Interview, negotiation, and family conversation scenes often become overly theatrical.

Generate a 30-second dialogue video with natural, brief, asymmetric micro-expressions while preserving identity consistency.

Training and evaluation favor visible expressions and rarely constrain subtle emotional muscle motion.

Blind review by performance or psychology evaluators, with over 70% of clips judged as natural micro-expressions.
