Product Demo With Synchronized Sound
Prompt Creek
Created August 21, 2026 · Updated August 22, 2026
Description
A hands-on product demonstration where the foley lands with the action, using Veo's native audio to sell the tactile quality of a physical object.
Instructions
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.
