@image is the first frame and the locked visual reference. Solid flat green chroma key background, perfectly uniform and static in every frame, locked lighting and exposure, no flicker, no brightness drift. Completely static and frozen: the building, columns, balcony, "МОСКВА" sign, rooftop structure, flagpoles, antennas, the parked bus, luggage carts, fence, pavement and its painted lines. No camera movement, no zoom, no pan. Pedestrians: a continuous flowing stream of people walking steadily along the square in front of the building, moving at a constant, even walking pace in the same general direction. As each person reaches the edge of the frame and exits, a new person enters from the opposite edge, matching the same general style of clothing, build, and walking pace as the people already in the scene, so the flow of pedestrians reads as constant and unbroken — the square always has the same overall density and mix of people, just continuously cycling through. The walking rhythm is steady and repetitive, like a closed loop of foot traffic. Loop requirement: the stream of people is designed as a perfect cycle — the pattern, density, and positions of people crossing the frame at the final frame must exactly match the pattern at the first frame, so that when the clip repeats, the flow of people continues seamlessly with no visible jump, gap, or pause in foot traffic. Single static locked-off shot, fixed camera, 10 seconds, seamless loop, chroma-key ready output. Vintage 1970s film color grade, soft natural grain.
