Create a photorealistic video: A young man (approximately 25-34 years old) with good posture walks directly away from the camera, **perfectly centered in the frame throughout the entire clip.** He is walking down a **visibly busy and populated city street filled with numerous other pedestrians moving around in the background.** He wears a black t-shirt featuring the exact graphic design from the provided input image, centered prominently on the back. **Maintain a consistent medium shot framing from behind, starting immediately at this distance; absolutely no initial zoom, no camera zoom, and no panning during the video.** The camera follows him smoothly. The focus must remain razor-sharp only on the man's back and the t-shirt design. **All background elements, including the many pedestrians and the street scene, must be rendered with a strong, heavy bokeh blur, making them clearly present but entirely out of focus and indistinct.** Use natural daylight and a street photography style.
