Define the Scene
Describe your Subject and Action. Be specific—"A weary astronaut" is better than "A person." Describe what they are doing with physical verbs.
DVP Tools / Prompt Engineering
Platform-Ready CinePrompt
Speak the language of AI video. CinePrompt uses Anthropic's Claude to transform your narrative vision into professionally structured, platform-optimized prompts for Kling, Runway, and Midjourney.
Quick start
Build your prompt in three moves
CinePrompt is a professional bridge. It takes your raw story beats and injects the technical cinematography, lighting, and movement data AI models crave.
Select the Target
Toggle the platforms you intend to use. CinePrompt crafts unique versions for each engine, matching their specific syntax and weighting preferences.
Generate and Copy
Review the formatted outputs. Each prompt is calibrated to minimize hallucinations and maximize adherence. Copy and paste directly into your chosen tool.
One app, three modes
Build, Translate, and Stills / JSON
CinePrompt carries three tabs along the top. Your scene description follows you between them, so you can move from a video prompt to a matching still without retyping.
Build Prompt
The core mode — guided cinematography controls assemble a platform-tuned prompt for video models (Kling, Veo, Runway, Luma, Pika, and more). Press ⚡ Preview Image to render a fast preview thumbnail of your prompt with your own fal.ai key, so you can see it before committing a full render.
Translate Prompt
Paste an existing prompt from any platform and rewrite it for several targets at once via Claude (bring your own Anthropic key). Useful when a look works on one engine and you want it everywhere.
Stills / JSON
The former JSON Prompt Builder, now a tab here. Build structured prompts for image models — Midjourney flags, FLUX / SDXL prose + tags, or JSON for Imagen / Gemini — with deep photographic controls. Use Use current Build scene → to carry a video scene over, and ↩ Send scene to CinePrompt Build to bring an idea back.
Methodology
Engine Calibration
CinePrompt doesn't just "rewrite" your prompt; it re-architects it based on current platform benchmarks and latent space mappings.
The Platform Filters
Every engine has a different "sweet spot" for description. Our tool adapts your vision to match.
- Kling Motion-first, emphasis on physical interaction.
- Runway Cinematic terminology and lighting focus.
- Midjourney Descriptive style and reference weighting.
- Luma Tonal consistency and environmental bed.
- Veo Narrative arc and temporal stability.
Named Looks
Attach visual style data from FrameDNA. This ensures that the generated prompt includes the exact color temperature, grain, and contrast of your reference stills.
Tip
For best results, limit your platform selection to the 2-3 tools you actually plan to use. This allows Claude to focus on more nuanced variations.
Controls
Mastering the Input
Subject & Action
The "Hero" data. Describe clothing textures, facial expressions, and specific physical maneuvers to anchor the AI's attention.
Environment & Time
Set the stage. "Overcast afternoon in a brutalist library" provides 5x more signal than "In a library."
Camera Movement
Describe the lens and the move. Use Dolly Zoom, Handheld Shake, or Slow Push-in to guide the model's temporal engine.
Mood & Style
Emotional keywords. Use "Melancholic noir" or "Tense documentary" to steer the color and contrast logic of the generated output.
Prompt History
Recall your last 10 generations from browser storage. Iteration is faster when you can return to a previous baseline with one click.
Regenerate Logic
Not quite right? Hit Regenerate. Claude will provide a fresh variation with different emphasis while keeping your core parameters locked.
Professional Workflow
Shot Development
The DNA Integration
Scan a reference still in FrameDNA, save the look, and apply it here. It's the fastest way to maintain visual style across different prompt descriptions.
Motion Anchoring
If your action is complex, put it at the very start of the Kling prompt. CinePrompt does this automatically for most configurations.
Shot Type vs Camera
Describe the SHOT (Close-up, Wide) rather than just the CAMERA move. AI models respond better to framing terminology than spatial coordinates.
Consistency Keeper
Once you find a prompt that works, use the "Consistency Keeper" to lock those specific style tags for the rest of your scene.
