Request Body

application/json

These parameters come from the selected model form_schema. Switching models updates this list and the request example.

video_url*string

Required. Video to edit. Duration 3–60s, max 100MB.

RequiredExample Value: https://static.modelstream.ai/demo/happyhorse/happyhorse-1.0-video-edit_reference.mp4

reference_images?array

Optional. Upload images to guide the style or specific element modifications.

Value Range: 0 ≤ value ≤ 5

prompt*string

RequiredExample Value: Transform the girl into a celestial being made of translucent sapphire-blue glass. Her skin should have the texture of frosted cobalt crystal with glowing, silver-etched circuit patterns running beneath the surface. Her hair is to be replaced by flowing, weightless strands of deep-blue liquid starlight that trail behind her motion. The Hanfu must be transformed into a gown made of shimmering, semi-transparent solar-sail material in shades of azure and teal, reflecting a distant galaxy. The fan should become a cluster of floating, crystalline shards that move in perfect synchronization with her hand, emitting soft blue light and cold vapor. The background is a deep-space nebula with swirling clouds of violet and turquoise gas and distant, twinkling star clusters. Focus on the refractive quality of the sapphire skin, the metallic sheen of the silver etchings, and the fluid, weightless motion of the starlight hair. Every movement should leave a faint, glittering trail of stardust.Placeholder: Describe how you want to modify the video (e.g., change background to forest, or apply oil painting style)...
