Macro close-up of a pair of hands {{action}} with {{product}}, framed tight enough that the hands enter from the lower edge and the object sits centred. The movement is unhurried and deliberate, completing once across the length of the take with a brief pause at the end. The camera holds still on a locked-off macro axis. A hard key from camera right rakes low across the object, catching the machined edges and surface finish and throwing crisp shadows to the left; a soft fill keeps the underside readable. The background is a clean charcoal seamless falling to darkness at the frame edges. Shallow focus, roughly f/2.8 equivalent, holding critical sharpness on the point of contact.
Audio: {{sound-effect}}, close-miked and dry, landing exactly with the movement. Beneath it, quiet studio room tone. Aspect ratio: {{aspect-ratio}}.

How to use it

The entire point of this prompt is that the sound lands with the action, so choose the action and the sound effect as a matched pair — a magnetic clasp needs a click, a fabric sleeve needs a rasp. Set aspect ratio in the interface. Negative prompt (a Vertex AI parameter, written as plain nouns): subtitles, captions, text overlay, watermark, extra fingers, distorted hands. If the audio comes back generic, make the sound effect more specific rather than longer; naming the exact material doing the exact thing is what produces convincing foley. That parameter is undocumented in the Gemini API, so if you are generating in the Gemini app or Flow you may have no negative field at all — in that case lean on the positive description alone.
