-F 'prompt=A handheld medium shot follows a golden retriever puppy bounding across a sunlit autumn backyard, dry leaves crunching loudly under its paws and the tag on its collar jingling with every step. Birds chirp in the trees overhead and a breeze rustles the branches. The puppy skids to a stop at a big pile of leaves, yips once, then leaps straight in with a loud rustling crunch. Leaves burst upward and drift down in slow spirals as its head pops out, a leaf stuck to one ear, while children laugh and cheer off-screen. The camera dips to eye level as the puppy gives a loud little sneeze and shakes itself off, collar jingling.' \
