Each prompt should describe a short video clip featuring animals doing cute things. The final video should look surreal, yet realistic. THERE SHOULD BE NO HUMANS AT ALL. REMEMBER, THE FOCUS IS ON CREATING A VIDEO THAT IS SUPER ADORABLE.\n\nREQUIRED STRUCTURE (FILL IN THE BRACKETS BELOW):\n\n[Scene paragraph prompt here]\n\nMain character: [description of character]\nThey [describe a physical action: shifts position, glances around].\n\nEnvironment: [description of the setting]\n\nStyle: hyper-realistic, cinematic, highly detailed\n\nCamera: [camera movement, angle, framing]\n\nLighting: [lighting conditions]\n\nTime of Day: [day / night / dusk / etc.]\n\nLens: [describe lens]\n\nFilm Stock: [cinematic tone, e.g. Kodak Portra, cinematic film look]\n\nAudio: (include) [ambient sounds, e.g. lion growls, wind, distant traffic, birdsong]\n\nBackground: [detailed background elements]\n\n\nRULES FOR PROMPT GENERATION:\n\nSingle paragraph only, 750–1500 characters. No line breaks or headings.\n\nNo human character, ever.\n\nDo not include lines of spoken dialogue.\n\nCharacter must do something physical, even if subtle (e.g. glance, shift, small movement, camera interaction).\n\nDo not use selfie-style framing.\n\nScene must feel real and cinematic — like a short clip someone might record on a stylized camera.\n\nAlways include the five key technical elements: Time of Day, Lens, Film Stock, Audio, and Background.\n\n\nIMPORTANT RULES:\n\nDon't break the paragraph or use formatting.\n\nDon't write vague or abstract scenes — always keep them grounded in physical detail.\n\n\nDO NOT DO THIS:\n\nDon't name the character.\n\nDon't include more than one character.\n\nDon't describe subtitles or on-screen text.\n\nDon't break the paragraph or use formatting.\n\nDon't write vague or abstract scenes — always keep them grounded in physical detail."
