Your prompt

Create TWO separate 4 seconds 4:5 clips to be placed side by side in an editor. Generate them one at a time. Clip A (reaction): a fictional a man in his twenties in a plain t-shirt, framed head and shoulders, reacting to something off-screen with wide-eyed surprise turning into an impressed smile, looking toward the right side. Plain light grey background, soft even light, static camera. Clip B (demo): a stain being wiped off a white sneaker in one clean stroke with a shoe-cleaning foam, close-up, static camera, clear view of the result. Plain light grey background. Match: same lighting colour temperature and similar brightness between A and B. Sound: a soft wipe sound for the demo; no voice. Constraints: no on-screen text, no logos beyond the product's.

Example of what to expect

Illustrative only. It describes the kind of result this prompt aims for; real output varies by tool, model and run.

Two separate matched clips: a reactor looking right in surprise, and a close-up of a stain wiped from a white sneaker, to be placed side by side.

Expected format: Two clips to composite in a video editor.

How to use it

  1. Generate A and B separately and composite them.
  2. Ensure the demo result is something the real product can do.
  3. Do not present a synthetic reactor as a real customer.

Limitations

  • Demonstrations of product efficacy that the product cannot deliver are misleading; use real footage for proof.
  • Matching lighting across clips takes manual correction.

Platform notes

Google video models (Gemini Omni Flash, Veo 3.1)

Official docs read · checked 2026-10-11

Google's Gemini API docs describe Veo 3.1 as generating video with native audio, and name Gemini Omni Flash as the recommended default; check current limits for duration and resolution, which the docs page did not list.

General notes on Google video models (Gemini Omni Flash, Veo 3.1)
  • Google's Gemini API docs name Gemini Omni Flash as the recommended default and Veo 3.1 for native audio, video extension and first/last-frame control.
  • Google's detailed Veo prompt guide could not be fully read, so structure here follows general video-prompt anatomy, not Veo-specific claims.

Runway (Gen-4.5 and earlier)

Official docs only partly readable · checked 2026-10-11

Per Runway's help center (seen via search snippet), with image-to-video the image is the first frame, so describe the motion rather than the scene.

General notes on Runway (Gen-4.5 and earlier)
  • Per Runway's help center (seen via search snippet), Gen-4.5 supports text-to-video and image-to-video. With image-to-video the image is the first frame, so describe the motion instead of re-describing the image.

Any text-to-video or image-to-video tool

Official docs only partly readable · checked 2026-10-11

Plain scene description that any text-to-video tool can use. OpenAI shut down Sora 2 and its Videos API on 2026-09-24, so no prompt here targets Sora.

General notes on Any text-to-video or image-to-video tool
  • Written as plain scene descriptions: subject, action over time, camera, lighting, style, aspect ratio. Duration, resolution and aspect ratio are usually settings in the tool, not words in the prompt.
  • OpenAI shut down Sora 2 and its Videos API on 2026-09-24, so none of these prompts target Sora.
