If you’re not used to crafting prompts, tools like ChatGPT can help create them from keywords.

Example Input

Write a prompt for Animagine-XL with about 30 tags in English. Keywords: 🔵🔵, 🔵🔵, 🔵🔵.

When using Animagine-XL 4.0, I recommend keeping the officially recommended quality prompts like masterpiece, high score, great score, absurdres as they are.

Reference: EasyWanVideo and EasyForge

This time, I introduced installing ComfyUI with Stability Matrix, but using Zuntan’s EasyWanVideo or EasyForge makes it even simpler.

The Easy series uses a unique folder structure but includes various optimizations by Zuntan.
