How to Use TubePrompter

Getting Started

TubePrompter is an AI video analysis tool that helps you extract visual elements from YouTube videos and convert them into optimized AI prompts for image generation.

Step 1: Paste YouTube URL

Copy any YouTube video URL and paste it into the input field on our homepage. The tool works with any public YouTube video.

Step 2: AI Analysis

Our AI powered by Gemini 2.5 analyzes the video thumbnail and extracts key visual elements:

  • Camera angles and positioning
  • Lighting setup and direction
  • Composition and framing
  • Visual style elements

Step 3: Scene Selection

Browse through the analyzed scenes in the timeline. Each scene represents a different moment or transition in the video with its own visual characteristics.

Step 4: Remix and Customize

Use the Remix panel to customize the generated prompts:

  • Subject Variable: Change the main subject (e.g., "person running" → "dragon flying")
  • Style Modifier: Add artistic styles or themes
  • Locked DNA: Keep camera and lighting settings for consistency

Step 5: Generate and Use

Generate your final AI prompts and use them with:

  • Midjourney
  • Stable Diffusion
  • DALL-E
  • Other AI image generators

Advanced Techniques: The "DNA" Method

TubePrompter introduces the concept of "DNA Extraction". Instead of just describing a scene, we extract the immutable characteristics that define its style.

🧬

Structure DNA

Composition, Rule of Thirds, Leading Lines

💡

Lighting DNA

Color Temperature, Contrast Ratio, Falloff

🎥

Camera DNA

Focal Length, Shutter Angle, ISO Grain

Pro Strategy: Lock the "Lighting DNA" and "Camera DNA" but swap the "Structure DNA" to place different subjects into the exact same cinematic mood.

Best Practices

  • Choose high-quality videos: Better source material produces better prompts
  • Experiment with subjects: Try different subject variations while keeping the visual DNA
  • Refine iteratively: Use generated images as reference to improve your prompts
  • Combine elements: Mix and match elements from different scenes
