A photorealistic cinematic VFX video using the uploaded reference person as the main subject. Preserve his identity, face, hairstyle, beard, glasses, beige blazer, white shirt, white pants, and brown shoes. He appears as an enormous giant man, as tall as a skyscraper, walking slowly through Bangkok, Thailand.


Scene setup: broad daylight, realistic daytime atmosphere in Bangkok, soft natural sunlight, light tropical haze, believable Thai urban environment, city streets, moving cars, realistic building scale, and subtle environmental depth. The giant man walks carefully and slowly between buildings in central Bangkok. He gently touches the side of a building with one hand as he walks past, with only a subtle physical reaction, no major destruction, no collapsing structures.


Camera style: realistic smartphone point of view from street level, handheld, natural human-operated framing, slight hand shake, documentary realism. The footage should feel like it was captured by a bystander using a smartphone, but the smartphone itself must never appear in frame. Start with a medium-wide view showing the giant man in the city, then do a slight digital zoom toward his face while he continues walking. The zoom should feel like a real smartphone zoom, subtle and imperfect, not cinematic lens perfection.


Action details: the giant man walks very slowly and calmly, with realistic weight and body mechanics. His footfalls feel heavy and believable, with subtle ground vibration and proper inertia. His body balance, posture, and arm movement must follow real-world physics. His clothing moves naturally with motion and wind. He has a calm, neutral expression, not aggressive. He lightly places his hand against a building while passing by. A helicopter flies across the scene at mid-height near him, passing naturally through frame to emphasize scale. The helicopter should have realistic speed, rotor blur, and physical presence.


Physics and realism: emphasize accurate scale, realistic body motion, realistic lighting, realistic shadows, realistic reflections, realistic atmospheric perspective, and believable interaction between the giant figure and the environment. Keep the VFX grounded and physically correct. No cartoon motion, no superhero posing, no exaggerated destruction, no floating or weightless movement.


Style: ultra realistic, grounded VFX, documentary-like realism, authentic smartphone video feel, natural colors, realistic motion blur, highly detailed, believable daylight.


Negative guidance: avoid cartoon style, avoid oversaturated colors, avoid CGI glossiness, avoid face distortion, avoid anatomy errors, avoid extra limbs, avoid unrealistic building collapse, avoid fantasy effects, avoid dramatic action poses, avoid showing the smartphone or the person filming.
