Example Prompts：
Gaming Channel
“A wide YouTube banner in a futuristic, cyberpunk style. A female cyborg soldier with a high-tech rifle and glowing neon tattoos is in a dynamic action pose. The background is a dark, neon-lit alley with holographic advertisements. The text "Glitch Fire" is written in a glitchy, distorted digital font in the bottom right corner. Vibrant colors like electric blue, purple, and pink dominate the scene.”
Tech Review Channel
“An abstract, dark-themed YouTube banner. Glowing streams of binary code (0s and 1s) flow across the screen, forming a complex data visualization. A bright, central area is cleared to prominently feature the title "Data Driven" in a sharp, modern, digital block font. The text itself appears to be constructed from light particles.”
Lifestyle / Personal Brand
“Cinematic YouTube banner. A person wearing a backpack stands on a mountain peak at sunrise, looking out over a sea of clouds. They are holding a vintage film camera. In the sky, the channel name "Your brand name is written in a bold, rustic, stamp-like font, as if stamped onto a travel journal. The atmosphere is adventurous, inspiring, and full of wonder. Golden hour lighting, highly detailed.”
Step 4: Generate and Refine
