10 seconds, 2.39:1, high-alpine heli-snowboarding documentary action, extreme backlight like the reference: sun blasting the lens, rotor-wash snow dust, violent wind.
Wardrobe (fixed): orange technical hardshell jacket, dark snow pants, snowboard boots, colorful reflective goggles; optional matte helmet or beanie (allowed) but hairline must stay identical.
Camera standard: ALEXA 35 look; Cooke 18mm + 40mm, 24fps, 180° shutter, T4.0–T5.6 for crisp snow texture; strong lens flare, slight film grain; highlight roll-off preserved.
Color: cold high-contrast alpine daylight, deep blue sky, bright white snow, orange jacket pops naturally (no oversaturation).
Sound (ambience only): helicopter rotor thump fading, wind roar, board edge carving hiss, snow spray impacts, jacket flap, breath.
0–2.5s (Establish impact): 18mm low-angle handheld near ground; @konglingchao stands side-on in rotor wash, raising one arm to shield goggles from snow dust; helicopter sits behind him slightly out of focus; snow particles streak across frame.
2.5–6.0s (Commitment move): whip-pan + match cut to 40mm medium tracking; he straps in / stomps binding once (single decisive动作), then drops into the slope; camera follows tight at hip height; sun flare blooms across his orange shell.
6.0–10s (Explosion run): switch to follow-cam / action-cam simulation (chest or trailing pole) with real vibration; first hard carve throws a wall of powder into lens → momentary whiteout; he immediately transitions into a second S-turn, edge spray sparkling in backlight; end on a fast pull-back showing him cutting a clean line down untouched snow.
