电梯复制人危机

8-second fixed security camera footage inside an elevator, ceiling corner angle, monochrome CCTV look, timestamp overlay. Time-lapse effect showing repeated use over time. People enter and exit in fast jumps across different timestamps. One specific person appears multiple times across different time points, always entering the elevator in the same way. As the sequence progresses, more copies of the same person begin appearing in different positions within the elevator at the same time. Final moment: the elevator is filled with identical copies, all turning their heads toward the camera simultaneously.
