What can a video-to-video API do?
Video-to-video models take an input video URL and return a transformed one: restyling, editing by prompt, upscaling, or extending footage. Each model’s page documents its exact inputs with runnable code examples.
How do I call a video-to-video model via the API?
Every model shares the same request shape: POST https://queue.modelrunner.run/<owner>/<alias> with an Authorization: Key header and the input fields as the top-level JSON body (no wrapper object), then poll the returned status_url and fetch the result from response_url. The JavaScript SDK (@modelrunner/client) wraps this in a single subscribe() call, which is the one place an { input } object is used. Each model page shows copy-paste cURL, JavaScript, and Python examples with that model's real inputs.
Can I run video-to-video models from Claude or Cursor?
Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and every video-to-video model in the catalog becomes a tool your AI assistant can call with the run_model tool — authorized via OAuth, no API key pasted into config.
