Wan 2.7 Reference-to-Video model with multimodal input support (text/image/video). Can generate single-character performance or multi-character interaction videos using reference characters. Supports intelligent multi-shot generation. 720P and 1080P resolutions, duration 2~10 seconds, billed per second. Output includes audio by default.
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.
