The walkthrough
Step 01 / 07
See what you're making
One continuous 30-second shot from a single Kling 4.0 generation. Our avatar walks from his desk through a rainy Tokyo alley, a rainforest, desert dunes, a snowy ridge, a coral reef, a city rooftop, a space station and the moon, then arrives back at his desk. There are no cuts: each new world sweeps in around him while he keeps walking. Two things make this possible in Kling 4.0, according to Kuaishou's launch announcement (19 Oct 2026): it makes up to 30 seconds of video in a single pass, and it takes up to 10 keyframes, so you decide exactly where the shot goes. The avatar is AI-generated. The keyframes, the prompt and the settings below are exactly what we used.
Step 02 / 07
Make your 10 keyframes
A keyframe is a still image of a moment you want the shot to pass through. You need 10 of them, all showing the same character: 1. The start (we used his home studio) 2 to 9. One image for every place the shot should pass through 10. The end (back in the studio, so the video loops) Make them with any image model. We gave Nano Banana a character sheet of our avatar as the reference and used the prompt below once per keyframe, swapping in the setting and lighting from this list: 01 Start: a modern home studio at night: a desk with a monitor glowing soft lime green, shelves and a closed door behind him; he has just stood up from the desk chair and walks toward camera. Lighting: warm practical lamps plus lime monitor glow, deep shadows. 02 Tokyo: a narrow neon-lit Tokyo side street at night after rain, wet reflective asphalt, glowing signs with abstract shapes only (no readable text), steam from vents. Lighting: magenta and cyan neon, reflections on wet ground. 03 Rainforest: a dense tropical rainforest path with giant ferns and hanging vines, mist drifting between tall trees. Lighting: god rays of sunlight cutting through mist, lush greens. 04 Desert: the crest of golden sand dunes at sunset, wind blowing fine sand off the ridge, endless dunes behind. Lighting: low warm golden-hour sun, long shadows. 05 Snow: a snowy mountain ridge high above the clouds, fresh snow, distant peaks. Lighting: bright cold blue daylight, light snow flurries. 06 Underwater: the sandy seabed of a clear tropical coral reef, colourful coral and a school of fish around him, bubbles rising. Lighting: sunlight beams filtering down through blue water. 07 Rooftop: a city skyscraper rooftop at night with a helipad, the skyline glittering behind, wind moving his hoodie. Lighting: cool night city light, red aircraft warning lights. 08 Space station: a bright futuristic space station corridor with white panels and a large window showing planet Earth. Lighting: clean white interior light, blue earthlight from the window. 09 Moon: the grey surface of the Moon, footprints in the dust, planet Earth hanging in the black sky. Lighting: hard white sunlight, pitch black sky, crisp shadows. 10 End: the same modern home studio at night as the start, he walks back toward the desk chair, the monitor glowing soft lime green. Lighting: warm practical lamps plus lime monitor glow, deep shadows. Using your own character? Replace the description of the man (cap, mask, hoodie) with yours. All 10 of our keyframes are in the next two steps.
