Free AI Video Prompt Generator - Seedance & Sora

What is the AI Video Prompt Generator?

The AI Video Prompt Generator is a specialized tool that transforms your vague video ideas into high-density, structured prompts for AI video generation models like Seedance, Sora, Kling, Runway, and Veo. It uses a unique "anti-AI" methodology to ensure your generated footage looks like genuine real-world recordings — home videos, documentary B-roll, surveillance footage — not AI-generated cinema.

Key Features

  • 7-Segment Structured Output: Every prompt follows a professional template: Main Character → Location → Visual Style → Camera Style → Timeline → Audio → Goal
  • Anti-AI Technology: Actively suppresses AI default aesthetics (cinematic camera moves, perfect composition, commercial color grading) by injecting device-specific physical imperfections
  • 8 Device Aesthetic Packages: 2000s DV camcorder, 80s-90s VHS, 8mm film, smartphone, GoPro, CCTV, professional documentary, webcam — each with authentic flaw characteristics
  • Multi-Language Output: Generates prompts in English, Simplified Chinese, Traditional Chinese, and Japanese
  • Non-Perfect Event System: Each timeline shot includes exactly one imperfection (focus hunting, breeze moving hair, stray cat entering frame) to create authentic, unscripted feel
  • Self-Checking: Automatically verifies all 8 anti-AI checklist items before delivering the prompt

How to Use

  1. Describe your video idea — Tell the agent what you want to see. Be as specific or vague as you like.
  2. Specify the device/era (optional) — Mention if you want a specific look (DV camcorder, VHS, smartphone, etc.)
  3. State the emotional goal (optional) — Warm nostalgia, lonely isolation, tense unease, calm meditation
  4. Choose your language — The agent auto-detects your input language. Type "all 4 languages" for multi-language output.

Example

User Input: "A girl walking through a Tokyo alley at dusk, 2000s DV camcorder feel, warm and nostalgic"

Example: Anti-AI Video Prompt Output

Generated Output: The agent produces a complete 7-segment structured prompt with device-specific flaws (DV compression artifacts, autofocus hunting, handheld shake, exposure fluctuation), a 5-7 shot timeline with non-perfect events (stray cat crossing, breeze moving hair, sudden cut to black), and matching ambient audio — all in your chosen language.

Tips

  • Be specific about the device: The camera style is the most important segment for anti-AI realism. "DV camcorder" produces very different results from "smartphone vertical" or "CCTV."
  • Avoid abstract adjectives: Instead of "beautiful sunset," say "golden hour light filtering through power lines, casting moving shadows on a weathered wall." The agent will help you translate abstract concepts into concrete visual phenomena.
  • Use the adjustment knobs: After generating, you can fine-tune by changing the device package, time period, emotional keywords, or closure method.
  • For long videos (>15 seconds): Ask the agent to split into multiple prompts, keeping the character segment identical for continuity.
  • English prompts often work best with most AI video models, even if your native language is different. Try generating in English for the best model performance.

FAQ

Q: Which AI video models are supported?
A: The prompts work with Seedance, Sora, Kling, Runway Gen-3, Veo, and most text-to-video models. The structured format is model-agnostic.

Q: Can I use this for non-realistic styles like animation?
A: Yes! The 7-segment structure remains the same, but the camera style section adapts to the target medium's parameters (e.g., animation frame rate, commercial lighting instead of documentary natural light).

Q: Why do the prompts include negative constraints like "No music. No stabilization"?
A: AI video models have strong defaults that make output look artificial. Negative constraints actively suppress these defaults, allowing the realistic aesthetic to come through.

Q: Can I optimize an existing prompt?
A: Yes! Paste your existing prompt and the agent will diagnose which segments are missing or weak, then rewrite it following the 7-segment template.

Q: How do I get prompts in all 4 languages at once?
A: Simply type "all 4 languages" or "all languages" in your request, and the agent will output English, Simplified Chinese, Traditional Chinese, and Japanese versions sequentially.
