Duration: 10 seconds
Aspect ratio: 9:16
Reference: [Image 1], locking in the protagonist's face, hairstyle, and character design, no changing of clothes
Audio: Realistic urban night ambient sounds, running footsteps, howling strong winds, low-frequency rebound of the elastic device, landing thud, friends cheering; no dialogue, no subtitles
Overall style: Extreme sports mobile phone handheld shot, real high-altitude distance, one-shot, slight handheld shake and motion blur, reject game CG feel
GLOBAL CONTINUITY
Setting: Nighttime city high-rise rooftop, green helicopter pad, low concrete parapet wall, a vertical street canyon between two high-rise buildings, vehicles and streetlights far below.
Lower apparatus: A huge circular black elastic rebound device in the middle of the street, a continuous rainbow light strip around the outer ring.
Main subject: [Image 1] is the sole protagonist: copy the exact face from [Image 1] (the face shape, eye color and eye shape, eyebrows, nose, mouth, skin tone, age, hair color, hair length and hairstyle, and any beard, moustache, glasses or freckles), so their friends recognize them at once; consistent throughout, never morph. If [Image 1] shows an animal, the protagonist is that animal.
Bystanders: Three to four friends stand on the left side of the rooftop, filming with phones.
CAMERA CONTINUITY: One-shot by a friend on the rooftop with a phone, no cuts.
STUNT ENGINE: Rooftop run-up → Leap over parapet → High-altitude descent → Hit the center of the elastic surface → Deep depression → Strong rebound → Mid-air tuck and flip → Feet return to the same rooftop → Cheering celebration.
SHOT 1 (00:00-00:10)
00:00-00:01.50 | Run-up: The protagonist glances back at the camera with an excited grin, the face large and sharp, then runs to the edge.
00:01.50-00:02.30 | Leap: They leap over the low parapet, arms spread; the filmer rushes to the parapet and tilts down.
00:02.30-00:04.80 | High-altitude descent: Almost vertically top-down, the protagonist falls fast, arms spread, accurately targeting the center of the device.
00:04.80-00:05.50 | Hitting the center: The black elastic surface clearly caves in, then rebounds with great force, propelling the protagonist vertically upward.
00:05.50-00:08.20 | Rebound and flip: They rise up the same vertical path, the camera tilting up, one tuck flip near roof height.
00:08.20-00:09.40 | Landing: Both feet land on the green pad, knees deeply bent.
00:09.40-00:10.00 | Celebration: The protagonist cheers into the camera, the face large and sharp; friends rush in.
Constraints: A professionally staged fictional extreme sports scene. The device clearly catches and rebounds the protagonist, never an unprotected fall; descent and ascent on the same vertical line, not flying or ropes.
