1. Prompt Guidelines

1.1 Key Principles

• Be Specific: Clearly describe the scene, characters, actions, and environment. The more detailed the prompt, the better the output.
• Use Descriptive Language: Include adjectives, adverbs, and sensory details to enhance the visual and emotional impact.
• Incorporate Motion: Describe dynamic actions (e.g., "a bird flying gracefully") to leverage Wan 2.1's strength in motion generation.
• Leverage Physical Laws: Mention realistic physical interactions (e.g., "water splashing") for more authentic results.
• Specify Style and Mood: Indicate the desired artistic style (e.g., "cinematic," "cartoonish") or mood (e.g., "serene," "intense").

1.2 Advanced Techniques

• Prompt Enhancement: Use tools like Dashscope API to expand and refine your prompts for better results.
• Negative Prompts: Specify what you don’t want in the video (e.g., "no blurry backgrounds") to guide the model.
• Multilingual Support: Wan 2.1 supports both English and Chinese prompts, making it versatile for global users.
