Prompt Engineering for Video Models

Learn how to craft effective prompts for MiniMax video generation models to create stunning visual content.

Understanding Video Generation Prompts

Video generation prompts need to be more descriptive than text prompts, focusing on visual elements, motion, and cinematic qualities.

Key Components of Video Prompts

Visual Description

What you want to see in the video

Motion and Action

How elements move and interact

Style and Aesthetic

Visual style and artistic direction

Technical Parameters

Resolution, duration, and quality

Basic Video Prompt Structure

Simple Text-to-Video Prompts

# Basic video prompt
basic_prompt = "A cat playing with a ball of yarn"

# Enhanced video prompt with more detail
enhanced_prompt = """
A fluffy orange cat playing with a red ball of yarn in a sunny living room.
The cat pounces and rolls around playfully with the yarn.

Prompt Optimization Strategies

Length and Detail Balance

  • Good for simple concepts - Focus on key visual elements - Example: “A cat playing with yarn”
  • Good for detailed scenes - Include motion and style - Example: “A cat playing with red yarn in a sunny room, pouncing and rolling playfully”
  • Good for complex scenes - Include multiple elements and transitions - Example: “A detailed scene with multiple characters and complex interactions”

Testing and Iteration

def test_prompt_variations():
    """Test different prompt variations for the same concept"""

    base_concept = "A person walking through a forest"

    variations = [
        # Basic
        "A person walking through a forest",

        # With mood
        "A person walking peacefully through a sunlit forest",

        # With style
        "A cinematic shot of a person walking through a misty forest at dawn",

        # With motion
        "A person walking briskly through a forest, with leaves crunching underfoot",

        # With atmosphere
        "A mysterious figure walking through a dark, enchanted forest with glowing mushrooms"
    ]

    return variations

# Test variations
variations = test_prompt_variations()
for i, variation in enumerate(variations, 1):
    print(f"Variation {i}: {variation}")

Best Practices

Do’s and Don’ts

✅ Do's

  • Be specific about visual elements - Include motion and camera movement - Specify lighting and atmosphere - Test different variations - Consider the target audience

❌ Don'ts

  • Don’t be too vague about visuals - Don’t ignore motion and pacing - Don’t forget about lighting - Don’t use overly complex language - Don’t ignore technical constraints

Common Mistakes to Avoid

Problem: “A nice scene” Solution: “A peaceful garden with blooming flowers and a small fountain”
Problem: “A car on a road” Solution: “A car driving smoothly along a winding mountain road”
Problem: “A person in a room” Solution: “A person in a modern, minimalist room with soft lighting”
Problem: Too many conflicting elements Solution: Focus on 2-3 key visual elements
