Core Formula
Each prompt is assembled from 5 segments:
[Subject & Action] + [Setting & Framing] + [Camera Module] + [Lighting & Vibe] + [Platform Params]
Camera Module
Automatically selected based on the scene's atmosphere; the user may override it.
Module A — ARRI (realistic / narrative / literary and austere)
- ARRI ALEXA Mini, Zeiss Master Prime 35mm lens
- shallow depth of field, natural skin tones, organic film grain
- Suitable for: drama films, character portraits, slice-of-life narrative, independent film
Module B — RED (epic / sci-fi / widescreen tension)
- RED Weapon Dragon 6K, Panavision Anamorphic 35mm lens
- anamorphic lens flare, wide cinematic framing, epic scale
- Suitable for: sci-fi scenes, war films, grand landscapes, historical epics
Module C — Sony (sharp / cyber / extremely high contrast)
- Sony CineAlta F65, Panavision Primo Prime 35mm lens
- razor-sharp detail, high dynamic range, clinical precision
- Suitable for: cyberpunk, futuristic cities, tech-oriented scenes, neon night scenes
Lighting Presets
Automatically matched to the atmosphere; no longer locked to a single lighting setup.
| Preset | Keywords | Suitable Scenes |
|---|---|---|
| Golden Hour | warm golden light, long shadows, amber tones, soft rim lighting | Warm / nostalgic / pastoral |
| Cold Noir | cool blue-steel tones, low-key lighting, deep shadows, muted palette | Film noir / suspense |
| Neon Cyber | neon-drenched, high contrast, saturated colors, electric glow, rain-slicked reflections | Cyberpunk / night scenes |
| Natural Doc | natural available light, neutral color grading, organic shadows, photojournalistic feel | Documentary / realistic |
| Desolate | low contrast, muted desaturated tones, overcast diffused light, desolate atmosphere | Wasteland / post-apocalyptic |
| Dramatic | harsh directional spotlight, deep chiaroscuro, strong rim light, theatrical contrast | Dramatic / portrait |
Platform Parameter Comparison
| Item | Midjourney | Gemini 3 Pro |
|---|---|---|
| Suffix parameters | --ar {ratio} --style raw --v 7 |
No parameters added; keep pure descriptive sentences |
| Aspect ratio format | --ar 16:9 |
Written into the description:in 16:9 cinematic aspect ratio |
| Style control | --style raw Avoid over-stylization |
Specify style keywords directly in the description |
Prohibited list
The following empty filler words are prohibited from appearing in the generated prompt:
beautiful, masterpiece, amazing, stunning, gorgeous, breathtaking, perfect, incredible, wonderful, magnificent
These words provide no visual information and only consume tokens. Replace them with concrete descriptions.
Workflow
Step 1 — Parse ARGUMENTS
Read the scene description provided by the user. If the description is too short (< 10 characters), go directly to Step 2 to fill in details.
Step 2 — Confirm preferences
Use AskUserQuestion to ask 3 questions at once:
Question 1: Atmosphere and lighting
- Golden Hour (warm golden light)
- Cold Noir (cold-toned suspense)
- Neon Cyber (neon cyber)
- Dramatic (dramatic strong light)
The user may select Other to customize, or specify Natural Doc / Desolate
Question 2: Composition and shot size
- Close-up (close-up, face detail)
- Medium shot (medium shot, waist-up)
- Wide shot (wide shot, full environment)
- Low angle shot (low angle, looking up, heroic perspective)
The user may select Other to enter bird's-eye view, Dutch angle, etc.
Question 3: Aspect ratio
- 16:9 cinematic (standard widescreen)
- 2.35:1 widescreen (cinema ratio)
- 1:1 square (social media)
- 9:16 vertical (mobile / Stories)
Step 3 — Scene expansion + module selection
Based on the information from Step 1-2:
- Expand the scene: expand the short description into concrete visual details (action, environment, materials, color)
- Select camera module: Automatically match based on atmosphere (realistic → A, epic → B, cyber → C), or follow user specification
- Optional lighting and shadow preset: Select the corresponding preset keywords based on the Step 2 atmosphere
- Banned words check: Confirm there are no empty decorative words from the banned list
Step 4 — Assemble output
Produce dual-platform formats using the following structure:
## 🎬 Midjourney Prompt
[Subject & Action], [Setting & Framing], shot on [Camera Module equipment],
[Lighting keywords], [additional mood/texture descriptors],
cinematic composition, film grain --ar {ratio} --style raw --v 7
---
## 🎨 Gemini 3 Pro Prompt
[Subject & Action], [Setting & Framing], shot on [Camera Module equipment],
[Lighting keywords], [additional mood/texture descriptors],
cinematic composition, film grain, in {ratio} cinematic aspect ratio
The core descriptions of the two prompt sets are the same; only the suffix parameters differ.
Output example

Panavision Anamorphic 35mm lens, low contrast, muted desaturated tones,
overcast diffused light, desolate atmosphere, anamorphic lens flare,
wide cinematic framing, subtle film grain --ar 2.35:1 --style raw --v 7
