🛠️ Setting Up Wan 2.1

1. Download ComfyUI for your OS
2. Choose between the 1.3B (lightweight) or 14B (high performance) version of Wan 2.1
3. Place files into the following folders:
   • Text Encoder → /models
   • Video Model → /models/checkpoints
   • VAE → /models/vae

✍️ Text-to-Video Workflow

Configure your settings in ComfyUI:

• Set resolution and output frame count (e.g. 69 frames ≈ 5 seconds)
• Use UniPC sampler with ~20 steps for good quality
• Enable frame interpolation to increase frame rate and fluidity

✒️ How to Write Powerful Prompts

1. Scene Description: “A female warrior stands in the ruins of a futuristic city...”
2. Action Detail: “Her long black hair flows in the wind...”
3. Camera Direction: “Camera follows from a low angle...”
4. Art Style: “Hyperrealistic, cinematic, dramatic contrast...”
