Sora提示词：Photorealistic video,

Photorealistic video, natural home-recording style, high clarity, realistic phone-camera quality

Fixed camera, medium-wide shot inside a Malaysian apartment bedroom, showing half of the room and the ceiling.

At the beginning, black mold stains are visible on ceramic ceiling tiles.

A person’s hand raises a mold-removal spray and sprays upward. A light white mist comes out of the nozzle.

The mold gradually fades and disappears, only decreasing over time, never increasing or spreading.

After the first spray, about half of the mold is gone. The hand pauses briefly, sprays again, and the remaining mold fully disappears.

The ceiling tiles and grout lines look clean and normal, not glossy, not over-polished.

Single continuous shot, no camera movement.

Neutral white ceiling light, slightly cool tone.

Everyday personal cleaning demonstration, realistic and understated.

No reverse effect, no mold growth, no stains appearing.
