@image is the first frame and locked reference. Solid flat green chroma key background, completely static — pure green, no flicker, no noise, no color shift. The building, its columns, balcony, "МОСКВА" sign, flagpoles, antennas, the parked bus, the luggage carts, and the pavement with its painted lines remain completely static for the entire duration — no camera movement, no parallax, no zoom, no lighting change. Only the pedestrians move, and their motion stays fully contained within the frame at all times — no one approaches the frame edges, no one exits or enters. Each person performs small, subtle in-place motion: a couple of short steps in one direction, a brief pause, then a couple of steps back to the starting position, light idle fidgeting — shifting weight, a small turn of the head, a slight sway, adjusting a bag or coat. Everyone stays roughly in their original spot on the square, just gentle restless micro-movement, like people waiting and milling about, not walking anywhere. No one changes overall direction abruptly at any point — all motion is smooth and continuous, oscillating back and forth without any sudden reversal or jump in pose. The first and last frame must match exactly in every person's position and pose, so the loop point is invisible and the motion reads as one continuous, gentle, fidgety oscillation when played on repeat. No new people appear or disappear at any point. Vintage 1970s film color grade preserved, soft grain. Single static locked-off shot, 15 seconds, seamless loop, chroma-key ready output.
