Wan 2.2 Professional Image-to-Video model generates a 5-second silent video based on the initial frame image and text. It offers significant improvements in visual detail and motion stability.
This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the video generation results.
Text prompt. Supports both English and Chinese, with a maximum length of 800 characters, and any excess will be automatically truncated.Example value: A small cat running on the grass.
Negative prompt, used to describe content that should be avoided in the video, allowing for restrictions on the video content.Supports both English and Chinese, with a maximum length of 500 characters. Any excess will be automatically truncated.Example value: Low resolution, errors, worst quality, low quality, incomplete, extra fingers, disproportionate, etc.
The URL of the initial frame image used for video generation.The URL must be publicly accessible and support HTTP or HTTPS protocols.Image restrictions:
Image formats: JPEG, JPG, PNG (no support for transparency), BMP, WEBP.
Image resolution: The width and height of the image should be within the range of [360, 2000] pixels.
Whether to enable intelligent prompt rewriting. When enabled, a large model is used to intelligently rewrite the input prompt. This significantly improves the generation effect for shorter prompts but increases processing time.
Random seed, used to control the randomness of the model’s generated content. The value range is [0, 2147483647].If not provided, the algorithm automatically generates a random number as the seed. To maintain relatively stable generated content, you can use the same seed parameter value.Example value: 12345.
