Put a line of tape on the floor and walk it. We'll put it between two skyscrapers Prompt: Use the reference video exactly: same young woman (short black bob, white long-sleeve top, black leggings, black slipper shoes), same side view at waist height tracking her left to right, same movements and timing along the line (three balanced steps, forward cartwheel landing on the line, two steps, standing backflip landing in a crouch with one hand on the line, rising to standing). Every human action identical. Replace only the green screen, green floor and white tape line, consistent from first frame to last, nothing appearing or transforming later: the white line is a taut steel tightrope cable stretched between the rooftops of two tall glass skyscrapers in a big modern city, hundreds of meters above the streets. She performs every step, the cartwheel and the backflip on the cable itself, feet and hand landing on it. The cable enters from the left anchored to one rooftop and exits right anchored to the other; below and behind her is open air with the city far below (streets with tiny cars, other skyscrapers, a river and bridges, late afternoon sun, light haze, a few birds far below). The cable sways slightly under her weight and bounces on each landing. Finish: photorealistic, correct depth and scale of the city below, sunlight and wind in her hair, her shadow not touching anything, film grain, warm cinematic grade, blockbuster look. Sound: wind at height, cable humming and creaking, her breath on each landing, distant traffic far below.

We won't forget to give you the prompt for the initial video Prompt: Stylized 3D art-toy character animation, Pixar-level render, 20 seconds, 16:9. The girl from the reference images (short wavy chestnut bob, brown cap with pins, freckles, rosy cheeks, dark brown oversized hoodie, olive cargo trousers, chunky trainers) on a seamless off-white studio backdrop, soft diffused light, playful squash-and-stretch cartoon physics. SHOT 1: Full body, she stands bored with hands in her hoodie pocket, side-eye. SHOT 2: Her head inflates like a balloon with a soft boing, she pats her cheeks in surprise, then it pops back to normal. SHOT 3: Her legs stretch taller, she wobbles and looks down, unimpressed. SHOT 4: A coloured light washes over her, orange to violet to electric blue, she shades her eyes. SHOT 5: The backdrop snaps from lilac to yellow to powder blue, she strikes a new pose on each beat. SHOT 6: Slow push-in to a close-up, she looks into camera, raises an eyebrow and smirks.

Opus 5.5 takes the image, draws in the doodles with Nano Banana, and then makes the movement with Kling 3.0 This person does not exist btw
