Scene overview: at dusk along waterfront athletic complex, athletes and citizens intertwineinrhythmic motion as the city awakens to the spirit of the2026Guangdong Provincial Games. This is the emotional prelude of an official teaser: every gesture honorslocalheritage and athletic aspiration, grounded and uplifting. Storyboard(each shot a separate scene, rapid cuts, all landing on the musical beats):[0s-1.5s]Shot1: wide drone-descending-to-eye-level: silhouette of a young sprinter exploding from starting blocks on the track, ocean glinting behind the stadium curves, wind lifting her hair and the corner of a red provincial games banner.[1s-2.5s]Shot2: medium tracking shot alongside: elderly fisherman on the adjacent pier pauses his net-mending to watch, weathered hands stilling as a para-swimmer glides through the open-water lane beside him, salt spray catching backlight.[2.5s-4s]Shot3: low-angle close-up: teenager’s worn running shoes pounding wet tarmac past lychee trees, fruit shadows dappled across her determined face, background blur showing children mimicking her stride with makeshift batons.[4s-5s]Shot4: freeze: the instant the sprinter’s hand touches the relay baton mid-transfer, fingers interlaced against the glowing stadium archway, golden light flaring softly, holdinginunified resolve. Camera: each shot its own angle, cuts clean and hard, no dissolves, gentle handheld intimacy during human moments, stabilized only on the final symbolic freeze. Audio: crashing waves, distant crowd murmur, rhythmic footfalls, traditional Cantonese percussion woven beneath modern score, a resonant gong strike on the baton pass, music cresting warmly at 4s, fading into ambient sea breathinthe last 1s. No text, subtitles, logos or watermarks of any kind, no animation or cartoon rendering, no overly-CG look, keep the live-action texture.参考[1] https://docs.comfy.org/tutorials/video/minimax/minimax-h3#minimax-h3-text-to-video-t2v
