Generate a complete, continuous, native 15-second 9:16 ad for a high-end blueberry ice cream product. Strictly follow the reference storyboard to execute 8 shots in sequence from left to right and top to bottom, generating only one continuous video without split screens, collages, chapter cards or storyboard grids. Use motion matching and two motivated full-frame occlusion cuts to connect shots, and don’t use cross-dissolve to allow subjects from different shots to overlap or deform and merge with each other.
[Product Lock] Whenever a product appears, it must strictly reproduce the same BLUMI CREAM ice cream cup as shown in the product appearance reference picture: short and fat cone-shaped paper cup, thick light lavender purple lid, deep indigo upper half, organic lavender purple cream dripping graphics, low saturated blueberry purple lower half; only the cream white round retro word mark "BLUMI" on the front, and the small letters "cream" below. The cup shape, cup lid, packaging graphics, color, word mark position and proportion will always remain unchanged, and no redrawing, no wording changes, or product duplication will be allowed.
[Product appearance and hiding schedule - must be strictly implemented] The product only appears in shot 1 from 0.00 to 1.05 seconds, and shots 7 and 8 from 8.80 to 15.00 seconds. In Shots 2–6 of 1.15–8.80 seconds, the product must completely disappear: no cup body, lid, label, cylindrical packaging, product silhouette or product residue is allowed to appear in the frame. Raw lenses must not cover the cup body.
00.00–01.00 seconds, shot 1: There is only a black silhouette of a BLUMI cup in the center of the dark purple studio, standing upright. The lavender backlight only outlines the thick cup lid and the outer contour of the cup body. There is a slight cold fog on the ground. Fixed composition, zooming in very slowly. There should be no blueberries, vanilla pods, milk drips or ice cream swirls at this time.
01.00–01.15 seconds, forced occlusion transition of shot 1→2: the camera quickly approaches the oval lavender backlight of the cup cover, and the highlight on the edge of the cup cover expands to all sides, completely filling the entire frame within 2–3 frames, forming a clean lavender-white full-frame light curtain. Only when the picture is 100% blocked by the light curtain will the hidden cut be completed inside the block; the cup must completely disappear within the light curtain. After the light curtain recedes, a completely empty deep purple space is first revealed, and then the raw material of lens 2 is allowed to enter from the edge of the frame. It is prohibited to cross-dissolve, the cup and the ingredients are not allowed to be in the same frame, and blueberries, milk drops or vanilla pods are not allowed to grow from the surface of the cup body.
01.15–03.00 seconds, shot 2: An independent macro low-gravity world. There are only blueberries with natural fruit frost, a real blueberry cut open, a natural vanilla pod and a few small creamy white milk droplets, floating in a clockwise trajectory in the empty deep lavender purple space, and the water droplets slowly break away from the peel. There is absolutely no product cup in the picture.
03.00–04.60 seconds, shot 3: The camera passes through a blueberry, and the texture of the blueberry pulp continuously changes into a thick ice cream swirl of creamy white and blueberry purple. Macro overhead shot, the vortex is rolled up clockwise, the texture is real and edible, with a small amount of vanilla seeds, blueberry berries and tiny ice crystals, not liquid splash.
04.60–06.00 seconds, shot 4: The center of the vortex bulges and is continuously shaped into a perfectly round blueberry-vanilla double-twisted ice cream ball. The ice cream ball rotates steadily and slowly in the air, with only a few ice crystals spreading out around it.
06.00–07.50 seconds, shot 5: A thick creamy white ribbon enters from the lower left and circles the ice cream ball clockwise for one and a half times. The ribbon is continuous, soft, and real, without breaking or passing through the ice cream ball.
07.50–08.80 seconds, shot 6: Three blueberries fall into the center of the soft vortex one after another, forming restrained and dense crown folds, producing only very few cream particles and no explosive splashes. The product cup must still not appear at this time.
08.80–10.80 seconds, shot 7: The same BLUMI cup rises slowly and vertically from the center of the vortex and is fully revealed. The product is always upright, facing the camera, and the packaging is not deformed. The cream ribbon can only pass through the back of the product, and the blueberries and vanilla pods can only surround the product in a clockwise direction outside the outer contour of the product; a clear safety gap is maintained around the product, and no blueberries, vanilla pods, cream or ice cream are allowed to pass through, stick to or cover the cup lid, cup body and BLUMI word logo. By 10.60 seconds, the product is fully formed and the front is clear, with surrounding raw materials giving way to the edge of the frame.
10.80–11.05 seconds, forced occlusion transition in shot 7→8: a single, wide, soft-edged blueberry-purple cream strip passes close to the camera from lower left to upper right at high speed, covering 100% of the entire frame within 2–3 frames, forming full-frame foreground occlusion. Only make a hidden cut at the moment when the cream band completely covers the screen, switching from the low-gravity vortex world to the purple mirror hero scene. After the cream strip leaves the scene, the same BLUMI cup has stood firmly on the mirror surface and is not allowed to fall, float, bounce, deform or regenerate. The central axis of the product, the front orientation and the elliptical angle of the cup cover before and after the masking are kept consistent. No cross-melting is allowed and no product is allowed to pass through the ice cream or cream strips.
11.05–15.00 seconds, Shot 8: The final hero’s makeup shot. The same BLUMI cup stands firmly on the purple mirror with controlled reflection. The complete ice cream ball, several blueberries and a vanilla pod have been quietly placed on both sides at the end of the transition, no longer suddenly appearing or sliding in. The two broad ribbons in cream white and blueberry purple stretch symmetrically in the background, but they are all located behind the product and do not pass through the cup body. All subject positions are locked after 11.80 seconds, and remain stable for at least 3.2 seconds, leaving only a very slight push-in, cold fog and highlight breathing; BLUMI and cream are clearly readable, leaving a clean title space above.
The overall design is film-level high-speed food advertising photography, with real edible texture, delicate ice crystals, natural fruit cream, slight condensation, controlled highlights, deep indigo shadows, soft lavender backlighting, shallow depth of field, and elegant slow motion. The direction of movement is uniformly clockwise, the lens is stable, the front is fast and the rear is stable. No people, no hands, no cutlery, no strawberries or any red fruit, no extra containers, no deformed packaging, no drifting labels, no garbled characters, no extra text, no plastic texture, no excessive melting, no flickering, no camera shake, no watermarks.
