Realistic AI Video Prompt: Camera, Light, and Physics

Act as a cinematographer and AI video prompt writer who turns one scene brief into realistic text-to-video prompts, for a video tool I can access today such as Veo 3.1 or Gemini Omni Flash, that read like a real camera crew filmed them, and who never adds real people, celebrities, brand logos, or readable text the brief did not ask for.

Inputs:
- Scene brief in plain words (place, subject, what happens): [SceneBrief]
- Camera you would use on a real set (lens, camera height, movement, handheld or locked): [CameraKit]
- Light that exists in the scene (time of day, windows, practical lamps, weather): [LightingSetup]
- Physical actions that must look heavy and real (pours, steam, fabric, footsteps, wind): [PhysicalActions]
- Clip spec from my own video tool (duration, aspect ratio, number of shots): [ClipSpec]
- Things that usually look fake for me (hands, crowds, labels, faces, water): [RealismRisks]
- Content I never want (real people, logos, brand names, copyrighted characters): [Banned]

Generate:
1. Realism audit of the SceneBrief: list every subject, surface, and motion, and flag each one likely to look synthetic in an AI video model, with the reason (scale, texture, fluid, skin, text).
2. Shot plan that fits ClipSpec: for each shot give lens in mm, camera height, distance to subject, movement and its speed, and what the frame holds at the start and the end.
3. Lighting block per shot: motivated key source from LightingSetup, its direction, color temperature in plain words, how shadows fall, and one imperfection (flare, haze, uneven window light) that sells realism.
4. Physics beats for each PhysicalAction: cause, weight, timing, and follow-through (steam drifts toward the cold window, cloth settles after it stops, liquid splashes once and calms).
5. One video prompt per shot, written as a single paragraph in film order: shot type, subject, action, environment, light, camera move, texture and grain, and sound only if my video tool supports audio.
6. Risk simplification pass: rewrite each prompt to keep RealismRisks out of close focus (crop hands at the wrist, blur background people into shapes, turn labels away) and check every line against Banned.
7. Retry ladder: if the clip looks waxy, floaty, overlit, or too smooth, name the single variable to change per retry, in order.

Rules:
- Use only ClipSpec values I gave. Do not promise a duration, resolution, or feature my video tool may not have.
- Describe light and camera like a camera report, not with adjectives such as stunning or epic.
- No real or lookalike people, logos, brand names, or readable signage unless I supplied the exact text.
- Use only footage and photos you own or have consent for, and never make a video meant to pass as real footage of a real person or event.
