Un 428 - Anku Rani. Scoring Cultural Accuracy.

**Anku Rani**, a doctoral researcher at **MIT** and an **MIT Tata Center** fellow, joins **Gabriella Mirabelli** to challenge a working assumption in AI video production: that a better-looking clip is automatically a better clip. Rani built a culture score that separates identity, behavior, and context, then tested it against leading video generation models and against real viewers from nine countries. The results complicate how brands should think about choosing a video model for global campaigns, especially once cinematic polish and cultural accuracy start pulling in opposite directions.
