Wan 2.1 Prompting Guide

⚠️ Important: Always use Image-to-Video (I2V) mode for reference. The model does not understand abstract concepts well without visual guidance.

If you need fixed poses or longer, controlled shots, switch to First-Last Frame to Video (FLF2V) mode instead.

General Guidelines

Use natural language to describe specific actions — avoid abstract concepts or keyword-stuffed phrases like in traditional AI image generation.

• ✅ "The girl slowly lifts her right hand to adjust her sunglasses."
• ❌ "Girl, hand, sunglasses, cool pose, stylish."
• ❌ "Doing something cool with her hands."

Focus on one action per shot. Don't describe multiple actions in a single prompt, or the model may not be able to complete them within 5 seconds.

• ✅ "The man waves his hand and smiles at the camera."
• ❌ "The man walks into the room, picks up a book, reads a bit, then waves."
• ❌ "She turns, waves, and jumps in excitement."

Be specific about which body parts are involved, what kind of clothing is worn, and what exactly is happening — avoid vague terms like 'clothes'.

• ✅ "She pulls down the hood of her gray hoodie with both hands."
• ❌ "She fixes her clothes."
• ❌ "The character interacts with her outfit."

Avoid overly complex or large movements for now, such as bending over or torso twisting, as they may result in glitches or fail to render properly.

• ✅ "He raises his left arm and points forward."
• ❌ "She bends down to tie her shoes."
• ❌ "The dancer spins twice and stretches backward."
