Examples
Same input, two HappyHorse generations
Prompt
Using Image 1 as the reference, replace the woman's clothing in the source video with the misty-blue Ming dynasty hanfu. Keep the garment fitted to her body and motion, let the wide sleeves move naturally with her arms, and preserve the layered collar and front panels as she turns. Match the crane and floral embroidery, fabric sheen, shadows, and material response to the original lighting. Keep her expression, hairstyle, skin tone, environment, and camera path completely unchanged.
Prompt
Using the visual characteristics of Image 1, transform the entire source video into a traditional black-and-white Chinese ink-wash painting. Rebuild the mountains, mist, architecture, and every visible element with expressive brushwork and varied ink density while keeping the original camera movement and scene structure unchanged. The result should feel monochromatic, atmospheric, and spatially coherent.
Prompt
Transform the entire video into the Minecraft voxel style based on the visual aesthetic of Image 1. Convert every subject, character, and environment into 3D blocks with low-resolution pixel textures, and match the lighting and colors of the reference world. Keep the original movement, character actions, and camera tracking path completely unchanged so the scene feels rebuilt inside a Minecraft world.
