Generate an 8-10 second 9:16 social video built around a fashion-era quick change. Keep one adult model centered in a simple runway, studio, or street set with the same face, body scale, and pose anchor throughout. Beat 1, seconds 0-2: establish the model in a clean neutral look, readable full-body or three-quarter framing, and a slight push-in. Beat 2, seconds 2-6: transform through four clear eras on the beat, such as 1960s mod tailoring, 1980s power silhouette, 2000s streetwear, and a clean near-future look; use match cuts, fabric ripples, spin turns, or light sweeps so each outfit change feels intentional rather than random. Beat 3, seconds 6-10: settle on the final look, let the model pause with a confident but natural expression, and hold a stable hero frame suitable for a social cover. Keep lighting direction, camera height, floor contact, hair continuity, and wardrobe edges coherent. Avoid real brand names, readable logos, celebrity likenesses, sexualized styling, body shape drift, warped hands, duplicated models, abrupt teleport cuts, random props, and extra scenes that weaken the fashion timeline.
