Create a 6-second vertical 9:16 ultra-realistic fashion video using the first image as the starting frame and the second image as the ending reference. 0–3 sec: the man walks naturally on the treadmill in the exact first outfit, preserving every clothing detail, accessories, proportions, treadmill, camera angle, lighting and interior exactly as shown. At 3 seconds, make a smooth invisible transition into the second look while keeping the same walking rhythm, body position and camera framing. 3–6 sec: the man must already be fully wearing the exact second outfit and continue walking naturally for the entire 3 seconds. Do not wait until the final frame to reveal the second look. He keeps walking continuously until the very last millisecond, with no stopping, posing or slowing down. Exact clothing fidelity to both reference images. No changes to garments, colors, fit, accessories, background or camera. Static camera, seamless transition, realistic natural walking
