Tech Product Ad: Rotating Fan
A high-precision prompt for creating a commercial-grade product video featuring a desk fan with specific mechanical button interactions.
Prompt
Generate a 12-second, 9:16 vertical, realistic movie-level tech product advertisement based on the reference product image.
The product must strictly match the reference image from the first frame to the last: a white desk fan, circular fan guard, ChatGPT six-petal vortex-shaped special fan blades, white rounded base, and the base must permanently maintain and only have 4 mechanical buttons.
The four buttons are permanently fixed from left to right: 1st (leftmost) = go; 2nd (left-center) = plus; 3rd (right-center) = pro; 4th (rightmost and largest) = reset. This is a fixed product structure. The video is strictly prohibited from changing the number, position, size, arrangement, and text of the buttons.
The highest priority is not recognizing the button text, but strictly executing the following physical space actions: leftmost button → move right one slot → move right one more slot → rightmost large button. Specifically: press the leftmost button first; press the 2nd button from the left second; press the 3rd button from the left third; finally press the rightmost largest button. The text go / plus / pro / reset is only for auxiliary recognition.
[Key Interaction Rules]
The first three button presses must be completed in the same continuous shot. From the first press of 'go' to the completion of the third press of 'pro': no camera cuts, no change in camera position, no left-right mirroring, no change in focal length, no orbiting, no regenerating the hand, no allowing the hand to leave and re-enter the frame. The camera is always directly in front of the product, looking slightly down at about 20°. Fully display the four buttons so they all exist in the frame simultaneously. A right hand enters from the bottom left of the screen. The index finger first hovers directly over the leftmost button. Afterward, the index finger can only move along a horizontal path from left to right. Returning to the left is strictly prohibited. The movement must be presented as a clear: PRESS → SLIDE RIGHT → PRESS → SLIDE RIGHT → PRESS. Move only the distance of one button each time.
[0.0-1.2s | Product Opening]
Pure white studio, white desktop. Fan is static. Front 3/4 product hero shot, showing the full fan. ChatGPT six-petal vortex blades clearly visible. Four buttons on the base clearly arranged: go | plus | pro | reset. Camera slowly dollies push-in. High-end tech product ad quality, 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 slightly looking down from the front of the product. No editing allowed from now until 4.8s. Simultaneously see: entire fan body, full base, full four buttons. Buttons fixed left-to-right: go | plus | pro | reset. A right hand enters from the bottom left. Important: hand must enter from the left, not the right. Index finger first stops directly over the 1st button 'go' on the far left. (1.4-2.1s): Index finger vertically downward, presses only the 1st button. Real mechanical sinking feedback occurs. Others remain still. Fan starts rotating at low speed. Index finger lifts again. (2.1-3.2s): Index finger stays in frame, slides horizontally right from the 1st button, moves one button distance. Stops over 2nd button. Vertically presses 2nd button. Fan speed increases. Index finger lifts. (3.2-4.5s): Index finger slides right again one button distance, stops over 3rd button, vertically presses it. Fan enters highest speed. (4.5-4.8s): Index finger lifts, hand leaves from bottom right. Fan keeps rotating at top speed. The first three operations must form a clear 'leftmost → second → third' visual trajectory moving left to right.
[4.8-6.0s | Wind Performance]
Switch to 3/4 side ad shot. Camera slides horizontally. Fan rotates at high speed. Vortex structure forms elegant motion blur. A thin white paper at the desk edge is gently moved by the wind. Restrained, high-end look. No hand in this segment.
[6.0-7.2s | Blade Macro]
Macro shot at very close range. Camera near fan center. Rotating six-petal blades form beautiful ChatGPT vortex. Central axis remains stable. Motion blur only on rotating structure. Real mechanical movement. No floating logos or 2D animation.
[7.2-8.6s | Hero Shot]
Low-angle 3/4 side. Fan runs at high speed. Camera slowly dollies out with slight orbit. White paper and silk ribbon sway. Button area remains: go | plus | pro | reset. No hand operation.
[8.6-10.0s | RESET]
Hard cut back to frontal fixed shot identical to 1.2-4.8s. Four buttons visible: go | plus | pro | reset. Hand enters from bottom right. Index finger appears directly over the large 'reset' button on the far right. (8.6-9.2s): Hover over large button for half a second. (9.2-9.7s): Index finger vertically downward, presses only the largest 4th button. Clear mechanical sinking. Others stay still.
[10.0-11.0s | Stop]
Reset is pressed, fan stops immediately.
