Dirt disintegrates

Make an 11-second, 9:16 ad for my upholstery cleaning business. The dirt on the sofa does not wipe away. It breaks into crumbs and dust right behind my cleaning tool and blows out of the frame, and the clean sofa is left behind. Footage: I attach a locked-off wide shot of my sofa where my extraction wand comes in and makes one clean stroke across the seat, a close-up of the dirty water in the clear nozzle, and a close-up of the nozzle on clean fabric. Track where the head of the wand touches the fabric every 0.2 seconds through the stroke, so the effect follows it exactly. Crop the wide shot about 20 percent so the floor under the sofa is out of the frame. The dirt: Make the sofa look clearly filthy in one glance on a phone. Lay a warm brown-grey dinge over it that follows the cushions' shading, heaviest in the middle of the seat and in the seams, with mottling and two or three stains with dark dried tide rings. No scattered dots. Grade the clean picture a little brighter and cooler, so clean reads as fresh. Hook, 0 to 1.5 seconds: Show the filthy sofa alone first, pushing in slowly, then rush the wand in at about 1.8x speed. Hero moment, 1.8 seconds: On the drop of the music, ease the footage down to about a third of normal speed with AI smoothing, just as the wand's head crosses the middle of the frame, and hold it there for 0.7 seconds. Right behind the head, the grime breaks into irregular crumbs and flakes of every size that lift off with a little motion blur, a soft haze curls up with them, and everything speeds up and blows up and to the right out of the frame, thinning as it rises. The dust moves in the same slow motion as the footage. The clean area never runs ahead of the wand. Then ease back up to about 1.1x to finish the stroke, so the whole sofa is clean before the cut on the beat at 3.7 seconds. Proof, 3.7 to 5.6 seconds: The dirty water churning in the nozzle, pushing in slowly. Brand, 5.6 to 10.8 seconds: The nozzle on fabric, covered in the same grime. My brand name peels off first, so its letters are clean fabric inside the dirt, in heavy Montserrat capitals about 225 pixels high in the lower third, with "Upholstery care" in small tracked capitals under it. At 7.5 seconds, on a downbeat, the letters turn white with a small punch and a soft shadow, and the rest of the grime crumbles and blows away from them. Sound: A clean, positive electronic track with a quiet build and a drop at 1.8 seconds, at 55 percent during the build and full from the drop. A riser and a soft sub hit land on the drop. A gust of air carries the dust, and again quieter when the letters peel. A tight slam when the letters turn white. Nothing else.
