Mastering AI Video Generation: The Art of Creating Effective Prompts with Wan 2.1
In today's rapidly evolving AI landscape, generating videos through artificial intelligence has become increasingly accessible. Wan 2.1 represents a significant advancement in this field, offering powerful tools that transform how to generate AI videos through well-crafted prompts. This guide focuses specifically on creating effective prompts—the secret sauce that determines the quality and accuracy of your AI-generated videos.
The Importance of Prompts in AI Video Generation
When learning how to generate AI videos, understanding that your prompt is the most critical factor in controlling the content and effects of your output is essential. The more complete, precise, and detailed your prompt, the higher the quality of your video and the closer it will align with your vision. Prompt engineering is truly the art behind successful AI video creation.
Understanding Wan 2.1's Core Features
Text-to-Video Generation
The most straightforward way to generate AI video content is through text prompts. Wan 2.1 allows users to enter detailed descriptions of their desired scenes, which the AI then transforms into fluid video sequences. The platform supports both English and Chinese inputs and offers multiple aspect ratios (16:9, 4:3, 1:1, 3:4, 9:16) to accommodate various platforms and devices.
A standout feature is the intelligent expansion capability, which enhances simple prompts by automatically adding details that significantly improve the richness and expressiveness of the final video output.
Image-to-Video Transformation
For those starting with existing visual assets, Wan 2.1 offers an image-to-video conversion feature. Users can upload an image to serve as the first frame, then describe the desired motion and camera effects with text prompts. The system supports flexible cropping options in any aspect ratio, giving creators precise control over the composition.
Prompt Structures: From Basic to Advanced
Basic Prompt Formula: Subject + Scene + Motion
For beginners just starting their journey with AI video generation, Wan 2.1 offers this straightforward formula:
- Subject: The main focus of your video (person, animal, object, or imaginary entity)
- Scene: The environment where your subject exists (background and foreground)
- Motion: The movements within your video (from subtle to dynamic)
Example: A graceful European woman in a long white dress, wearing a pearl necklace, sitting on a velvet chair in a Baroque-style room, with a soft smile on her face.
This simple structure provides the AI with the essential information needed to generate a cohesive video while still allowing creative interpretation.
Advanced Prompt Formula: Adding Rich Details
As you become more comfortable with how to generate AI videos, enhance your results with this expanded formula:
Subject (Subject Description) + Scene (Scene Description) + Motion (Motion Description) + Camera Language + Atmosphere + Styling
Breaking down each component:
-
Subject Description: Use adjectives and short phrases to detail appearances. For example: "A black-haired Miao girl wearing ethnic minority clothing" or "A flying fairy from another world, dressed in tattered yet elegant attire, with strange wings made of rubble fragments."
-
Scene Description: Provide details about the environment using descriptive language. The more specific you are about lighting, time of day, weather conditions, and spatial arrangement, the more precise your results will be.
-
Motion Description: Characterize movement by describing its amplitude, speed, and effects. Examples include "violently swaying," "slowly moving," or "shattering glass."
-
Camera Language: Specify shot types, angles, lenses, and camera movements to control how the scene is visually presented.
-
Atmosphere: Define the mood with terms like "dreamy," "lonely," or "grand" to influence the emotional quality of the video.
-
Styling: Describe the visual aesthetic using terms like "cyberpunk," "line-drawing illustration," or "post-apocalyptic style."
Specialized Prompt Techniques
Camera Movement Formula: Creating Dynamic Cinematography
For professional-quality results when learning how to generate AI videos, incorporate specific camera directions:
Camera Movement Description + Subject (Description) + Scene (Description) + Motion (Description) + Camera Language + Atmosphere + Styling
Example: Documentary Style, The camera follows smoothly, focusing on a European girl dancing alone on a spacious stage. She wears a classic white ballet skirt, its hem fluttering gracefully with her movements. Her expression is focused, her posture elegant, as if telling a silent story. The stage design is minimalist yet sophisticated, with soft lighting creating a warm and dreamy atmosphere. The background is blurred to highlight the subject. A transition from medium to wide shots captures both the dynamic motion of the dance and the overall beauty of the stage.
Pro Tip: Keep individual camera movements under 5 seconds to prevent overly complex sequences that might confuse the AI.

Transformation Formula: Creating Morphing Effects
For creative sequences featuring transformations:
Subject A (Description) + Transformation Process + Subject B (Description) + Scene (Description) + Motion (Description) + Camera Language + Atmosphere + Styling
Example: Anime style. On a street corner in the city, a black cat crouches under a lamppost, gazing at the distant neon lights. Suddenly, a beam of blue light descends from the sky, swiftly enveloping its body. The black cat leaps into the air, its fur gradually dissolving into the atmosphere as its body rapidly elongates. The fur transforms into a sleek black suit, outlining a tall, slender figure. The cat ears vanish, the facial features sharpen, and it eventually morphs into the handsome, stoic face of a teenage boy. He lands gracefully on the ground, his suit gently fluttering in the night breeze as the blue light fades, leaving him standing there like a mysterious youth stepping out of a futuristic world—elegant and confident.
This approach allows for creative storytelling through metamorphosis, opening new narrative possibilities.

Best Practices for Writing Effective Prompts
1. Be Specific About Visual Elements
When describing subjects or scenes, mention color, texture, materials, and distinguishing features. Instead of "a woman in a dress," try "a tall woman with auburn hair in a flowing emerald silk dress with gold embroidery."
2. Use Clear Motion Terminology
Be precise about movement. Instead of "walking," specify "confidently striding," "cautiously tiptoeing," or "sluggishly trudging." This precision helps the AI generate more accurate and expressive motion.
3. Balance Detail with Focus
While detail improves accuracy, too many competing elements can confuse the AI. Prioritize details that matter most to your vision and be selective about which elements you emphasize.
4. Consider Timeline and Sequence
When describing complex motions or transformations, present them in chronological order. This helps the AI understand the progression of events and generate a more coherent video sequence.
5. Experiment with Aesthetic Terms
Include references to artistic styles, film genres, or visual aesthetics like "film noir," "watercolor style," or "1980s music video aesthetic" to influence the overall look and feel of your video.
6. Iterate and Refine
The process of how to generate AI videos often requires experimentation. Use each generation as feedback to refine your prompts. If a specific element isn't appearing as expected, try different phrasing or add more descriptive details.
Common Prompt Challenges and Solutions
Challenge: Vague Results
Solution: Add specific details about color, texture, lighting, and exact positioning of elements.
Challenge: Unrealistic Motion
Solution: Break down complex movements into simpler sequences and use more precise verbs to describe motion.
Challenge: Poor Composition
Solution: Include camera language that specifies framing, such as "close-up shot," "bird's-eye view," or "rule of thirds composition."
Challenge: Inconsistent Style
Solution: Reinforce your desired style multiple times within the prompt and pair it with specific examples (e.g., "cyberpunk style with neon lighting and high contrast shadows").
