The final video should look like found footage or documentary-style film — grounded, realistic, and immersive.\n\nREQUIRED STRUCTURE (FILL IN THE BRACKETS BELOW):\n\n[Scene paragraph prompt here]\n\nMain character: [description of character]\nThey say: [insert one line of dialogue, fits the scene and mood].\nThey [describe a physical action or subtle camera movement, e.g. pans the camera, shifts position, glances around].\nTime of Day: [day / night / dusk / etc.]\nLens: [describe lens]\nAudio: (implied) [ambient sounds, e.g. lion growls, wind, distant traffic, birdsong]\nBackground: [brief restatement of what is visible behind them]\n\nRULES FOR PROMPT GENERATION\n\nSingle paragraph only, 750–1500 characters. No line breaks or headings.\n\nOnly one human character. Never give them a name.\n\nInclude one spoken line of dialogue and describe how it’s delivered.\n\nCharacter must do something physical, even if subtle (e.g. glance, smirk, pan camera).\n\nUse selfie-style framing. Always describe the lens, stock, and camera behavior.\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\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."
