A vertical ad for a white desk fan with four buttons go, plus, pro, reset, where a finger presses them in turn from left to right
Prompt
Generate a 12-second, 9:16 vertical, realistic cinematic tech product advertisement based on the reference product image. The product must strictly maintain consistency with the reference image from the first frame to the last: White desktop fan; Circular fan grille; ChatGPT six-petal vortex-shaped special fan blades; White rounded base; The base must permanently maintain and only contain 4 mechanical buttons. Four buttons fixed permanently from left to right: 1st, far left = go 2nd, left-middle position = plus 3rd, right-middle position = pro 4th, far right and largest button = reset This is the fixed product structure; it is strictly forbidden to change the number, position, size, arrangement, or text of the buttons throughout the video. The highest priority is not recognizing the button text, but strictly executing the following physical spatial actions: Far left button → move right one slot → move right one slot → far right large button. That is: 1st press: far left button; 2nd press: 2nd button from the left; 3rd press: 3rd button from the left; Final press: far right largest button. The text go / plus / pro / reset is only for auxiliary identification. ━━━━━━━━━━━━━━━━━━ 【KEY INTERACTION RULES】 The first three presses must be completed in one continuous shot. From the first press of go until the third press of pro is completed: No cutting shots; No changing camera angles; No horizontal mirroring; No changing focal length; No orbiting; No regenerating the hand; No letting the hand leave the frame and re-enter. The camera is always positioned directly in front of the product, looking down slightly at about 20°. Display all four buttons completely, ensuring all four are visible in the frame at all times. A right hand enters from the bottom left of the frame. The index finger first hovers directly above the far left button. Afterward, the index finger can only move along a horizontal path from left to right. Moving back to the left is strictly forbidden. The action must clearly present as: PRESS → SLIDE RIGHT → PRESS → SLIDE RIGHT → PRESS Move only one button distance to the right each time. ━━━━━━━━━━━━━━━━━━ 【0.0-1.2s | Product Opening】 Pure white studio, white desktop. Fan is stationary. Front 3/4 product hero shot, showing the full fan. ChatGPT six-petal vortex blades are clearly visible. Four buttons on the base are clearly arranged: go | plus | pro | reset Camera slowly dolly push-in. High-end tech product ad texture, soft studio lighting, natural shadows, realistic white plastic and metal materials. No human hand allowed at this time. ━━━━━━━━━━━━━━━━━━ 【1.2-4.8s | Continuous Three-Stage Operation Shot】 Hard cut to a fixed shot directly in front of the product, slightly looking down. From now until 4.8s, no editing is allowed. The frame clearly shows at all times: The entire fan body; The complete base; All four buttons. Buttons are fixed from left to right as: go | plus | pro | reset A right hand enters from the bottom left of the frame. Important: The hand must enter from the left, not the right. The index finger first stops directly above the 1st button (go) on the far left. ——1.4-2.1s—— Index finger moves vertically downward. Press only the 1st button on the far left. That is: The leftmost button. Real mechanical sinking feedback upon pressing. The remaining 2nd, 3rd, and 4th buttons remain completely still. Fan starts rotating at low speed. Index finger lifts after pressing. ——2.1-3.2s—— Do not let the index finger leave the frame. Index finger slides horizontally to the right from above the 1st button. Move only the distance of one button. Clearly cross the gap between the 1st and 2nd buttons. Stop directly above the 2nd button from the left. Then press the 2nd button vertically downward. Forbidden to jump to the 3rd button. Forbidden to return to the 1st button. Fan speed increases after pressing. 1st, 3rd, and 4th buttons remain stationary. Index finger lifts again after pressing. ——3.2-4.5s—— Index finger remains in the frame. Move horizontally to the right again from above the 2nd button. Still move only the distance of one button. Cross the gap between the 2nd and 3rd buttons. Stop directly above the 3rd button from the left. Then press the 3rd button vertically. The 3rd button is located: To the right of plus; To the left of the large reset. This is the third press. Fan enters maximum speed after pressing. Forbidden to touch the far right reset. ——4.5-4.8s—— Index finger leaves the button. Hand leaves from the bottom right of the frame. Fan maintains maximum rotation speed. The entire first three operations must form a very clear: Far left → 2nd → 3rd Continuous visual trajectory advancing from left to right. ━━━━━━━━━━━━━━━━━━ 【4.8-6.0s | PLUS / PRO Wind Performance】 Switch to a 3/4 side ad shot. Camera slides slowly laterally along the product. Fan rotates at high speed. Six-petal ChatGPT-style vortex structure forms an elegant motion blur with rotation. A very thin white piece of paper on the edge of the desk is gently blown by the wind. The frame remains restrained and high-end. No hands allowed in this segment. ━━━━━━━━━━━━━━━━━━ 【6.0-7.2s | Fan Blade Macro】 Extreme close-up macro shot. Camera approaches the center of the fan. High-speed rotating six-petal blades form a complete, continuous, beautiful ChatGPT-style six-petal interwoven vortex. Center axis remains stable. Motion blur only occurs on the rotating structure. Camera performs a very small orbit movement. Realistic mechanical motion. Forbidden to turn into a floating logo, 2D animation, or glowing special effects. ━━━━━━━━━━━━━━━━━━ 【7.2-8.6s | PRO Hero Shot】 Low angle 3/4 side view. Fan maintains high-speed operation. Camera slowly dolly-out while creating a very slight orbit. White paper and a very thin white ribbon sway under the wind force. Highlight the product's wind power and design sense. Button area still maintains: go | plus | pro | reset But no hand operation at this time. ━━━━━━━━━━━━━━━━━━ 【8.6-10.0s | RESET】 Hard cut back to the same front fixed camera angle as 1.2-4.8s. Do not change the left-right orientation. All four buttons appear completely in the frame: go | plus | pro | reset Where: reset is on the far right; reset is the 4th one; reset is the largest button; There is a clear gap between reset and the first three small buttons. This time, the hand enters from the bottom right of the frame. Note: The hand must enter from the right. The index finger appears directly above the far right large reset button. Do not pass through go. Do not pass through plus. Do not pass through pro. 8.6-9.2s: Index finger hovers only directly above the far right large button reset. Pause for about half a second to make the target position very clear. Forbidden to press any button at this time. 9.2-9.7s: Index finger moves vertically downward. Press only the 4th button, which is the largest in size. Must clearly see: Index finger is in the center of the large reset; There are no other buttons to the right of the index finger; pro is to the left of the index finger and is not touched at all. reset produces a mechanical sinking action as obvious as a traditional old-fashioned electric fan stop button. The other three small buttons remain completely still. ━━━━━━━━━━━━━━━━━━ 【10.0-11.0s | Stop】 After reset is pressed, stand
