Cinematic 9:16 vertical video, ultra-realistic. Split-screen composition (vertical split). Same person, same motion, same camera, same timing. [Main Concept] The exact same human walks down the exact same road. Only the background era is different. [Camera] Locked, smooth forward tracking shot from behind. No cuts. Continuous 12-second take. Perfect synchronization on both sides. [Character] Same person on both sides. Same clothes, same posture, same walking rhythm. Neutral expression. No interaction with objects. [LEFT SIDE — Past World] Edo-period Japan. Dirt road, wooden buildings, paper lanterns. People in traditional clothing move slowly. No electricity. No machines. The environment feels heavy, quiet, and time-consuming. [RIGHT SIDE — Future World] Near-future Japan. Same road geometry, but modernized. Clean pavement, subtle light lines embedded in the ground. Buildings are minimal, structured, efficient. No obvious technology screens — just clarity and order. [Key Rule] The person never changes speed. The walking motion is perfectly mirrored. [Ending — 10–12s] Both versions continue walking forward. No conclusion. No judgment. No text. No audio. Theme: Same human. Same effort. Different eras.
