For each scene include: 1. timecode and purpose 2. subject action and continuity constraints 3. camera framing, lens language, movement, and speed 4. lighting, palette, materials, environment, and atmosphere 5. transition into the next scene 6. a concise prompt that can be pasted into a video model End with one global negative prompt covering text, logos, watermarks, extra limbs, identity drift, flicker, and unwanted camera jumps.
