# Runway Gen-4.5 prompt · a puppy nudges a ball down the garden steps

SUMMARY AND ASSUMPTIONS
  Text to video, a fixed camera and one cause-and-effect action.
  The whole prompt uses positive phrasing: Runway does not accept negatives.

PROMPT FOR RUNWAY GEN-4.5
  A locked-off wide shot of a golden retriever puppy with floppy ears and a red collar
  sitting at the top of three stone garden steps, beside a yellow tennis ball. The
  puppy leans forward and nudges the yellow tennis ball with its nose. Then the ball
  rolls over the edge and bounces down the three steps, one at a time. After the last
  bounce, the puppy tilts its head and watches the yellow tennis ball settle on the
  grass. The garden is empty and quiet, with a plain green hedge behind the steps.
  Soft overcast daylight, realistic cinematic look.

SETTINGS IN THE TOOL
  - Mode: text to video (no image to upload).
  - Duration and format: whichever you prefer (for example, landscape); these
    are preferences to check against your Runway plan.
