Stop Prompting! (Train GPT to Write Your Video Prompts)

The Documentation Download That Changed Everything

Marcus had just finished his third failed attempt at generating the perfect establishing shot for his indie thriller. Runway ML gave him a floating car. Google Veo produced a medieval castle instead of modern cityscape. Midjourney’s video feature created something that looked like abstract art having a seizure.

“I’m reading these prompting guides wrong,” he muttered, switching between browser tabs filled with scattered documentation from Runway, Veo, Midjourney, and Pika Labs.

That’s when his developer friend Jake walked by and saw the chaos. “Dude, why are you manually reading all this? Download it all, feed it to a custom GPT, and let it write your prompts.”

Three hours later, Marcus had built his own AI prompting assistant loaded with the official documentation from every major video generation platform. Instead of deciphering complex prompting syntax, he simply described his vision: “Moody establishing shot of downtown LA at sunset, cinematic, film noir style.”

His custom GPT instantly generated perfectly formatted prompts for Runway, Veo, Midjourney, and Pika—each optimized for that platform’s specific requirements.

The Documentation Goldmine You’re Ignoring

Here’s what most filmmakers don’t realize: Every AI video platform has extensive documentation explaining exactly how to prompt their systems. The problem? It’s scattered across websites, constantly updated, and written in technical jargon.

But what if you could consolidate all of this knowledge into one AI assistant that speaks your creative language?

The Master Documentation Collection Strategy

Step 1: The Great Documentation Download

Target Platforms to Document:

  • Runway ML – Their prompting guide, style references, camera movement syntax
  • Google Veo – Technical specifications, prompt structure guidelines
  • Midjourney Video – Style parameters, aspect ratios, quality settings
  • Pika Labs – Animation controls, subject guidance, negative prompting
  • Stable Video Diffusion – Technical parameters, optimization tips
  • LumaLabs Dream Machine – Motion controls, scene composition guides

Download Process:

  1. Navigate to Documentation Sections
    • Go to each platform’s official documentation
    • Find their “Prompting Guide” or “User Manual” sections
    • Look for “Best Practices” and “Advanced Techniques” pages
  2. Capture Everything as PDF
    • Use Chrome’s “Print to PDF” function (Ctrl+P → Save as PDF)
    • For dynamic content, use tools like PrintFriendly or web scraping extensions
    • Save each platform’s docs in separate folders
    • Include example galleries and case studies
  3. Organize Your Knowledge BaseAI_Video_Documentation/ ├── Runway_ML/ │ ├── prompting_guide.pdf │ ├── camera_movements.pdf │ └── style_references.pdf ├── Google_Veo/ │ ├── technical_specs.pdf │ └── prompt_structure.pdf ├── Midjourney_Video/ │ ├── parameters_guide.pdf │ └── quality_settings.pdf └── [Continue for each platform]

Step 2: Building Your Custom Video Prompting GPT

Platform Setup:

  • Go to OpenAI’s GPT Builder (chat.openai.com/gpts/editor)
  • Create a new Custom GPT
  • Name it something like “Video AI Prompt Master”

System Instructions Template:

You are an expert video generation prompt engineer with comprehensive knowledge of all major AI video platforms including Runway ML, Google Veo, Midjourney Video, Pika Labs, and Stable Video Diffusion.

Your primary function is to take creative briefs from filmmakers and convert them into optimized, platform-specific prompts that generate high-quality video content.

CAPABILITIES:
- Convert natural language descriptions into technical prompts
- Optimize prompts for specific platforms based on their documentation
- Suggest camera movements, lighting, and style parameters
- Provide alternative prompt variations for experimentation
- Explain the reasoning behind prompt choices

INPUT FORMAT:
Users will provide:
- Basic scene description
- Desired mood/style
- Target platform(s)
- Technical preferences (resolution, duration, etc.)

OUTPUT FORMAT:
For each platform, provide:
1. Optimized prompt text
2. Recommended parameters/settings
3. Expected output description
4. Alternative variations
5. Platform-specific tips

Base all recommendations on the uploaded documentation from each platform.

Step 3: Upload Your Documentation Library

File Upload Process:

  1. Compress Your PDFs – Custom GPTs have file limits, so compress when needed
  2. Upload Systematically – Start with your most-used platforms first
  3. Test Knowledge Integration – Ask simple questions to verify the GPT can access the docs
  4. Iterate and Refine – Add more documentation as you discover gaps

Step 4: Training Your Prompt Assistant

Initial Training Prompts:

"I need a cinematic drone shot of a forest at dawn. Target platform: Runway ML. Style: Christopher Nolan cinematography."

Expected GPT Response:
RUNWAY ML OPTIMIZED PROMPT:
"Cinematic aerial drone shot flying over dense forest canopy at golden hour dawn, warm orange sunlight filtering through morning mist, camera movement: slow forward dolly with subtle altitude gain, Christopher Nolan style cinematography with deep focus and rich contrast, film grain texture, 4K resolution, 16:9 aspect ratio"

PARAMETERS:
- Motion: 8/10
- Camera: Drone aerial
- Duration: 4 seconds
- Style: Cinematic realism

ALTERNATIVES:
- Add "IMAX camera" for more Nolan authenticity
- Include "god rays" for dramatic lighting
- Specify "RED camera aesthetic" for film look

Real-World Implementation: The Case Studies

Case Study 1: Sarah’s Short Film Pipeline

Sarah downloaded documentation for Runway, Veo, and Midjourney, then trained her custom GPT with her project’s style bible. Now she feeds it scene descriptions like:

Input: “Tense conversation in cramped apartment, two characters, moody lighting, handheld camera feel”

GPT Output:

  • Runway ML: “Medium shot of two people in heated conversation, cramped apartment interior, dramatic chiaroscuro lighting with warm practicals, handheld camera movement with subtle shake, cinematic depth of field, 24fps film look”
  • Veo: “Interior apartment scene, two subjects in conversation, moody dramatic lighting, camera: handheld medium shot, movement: subtle camera shake, lighting: warm tungsten with shadows”
  • Midjourney Video: “Apartment interior –ar 16:9 –style cinematic –motion medium –lighting moody –camera handheld –quality high”

Case Study 2: Marcus’s Commercial Work

Marcus specializes in product videos. His custom GPT knows the documentation for all platforms plus his client’s brand guidelines:

Input: “Luxury watch on marble surface, rotating product shot, premium feel”

GPT Output: Platform-specific prompts optimized for product photography, complete with lighting specifications, rotation speeds, and material rendering instructions.

The Future of AI Video Creation

The most successful AI filmmakers aren’t those who memorize every platform’s documentation—they’re those who systematically capture and leverage that knowledge through AI assistants.

While others are still googling “how to prompt Runway ML” for the hundredth time, you’ll have an AI assistant that knows every platform’s documentation inside and out, ready to generate perfect prompts on demand.

Marcus’s latest commercial just won a Clio Award. His secret? “I stopped reading documentation and started downloading it. My custom GPT knows more about video AI prompting than most platform engineers.”
