What input does wan2.6-i2v require?
Use the image URL image_url to provide the starting frame, and use prompt to describe the subject's actions, scene changes, and camera movement. When calling it, select model=wan2.6-i2v and explicitly set action=image2video to avoid using the default text-to-video operation. Prompts should be written as brief shot descriptions.
How long and at what resolution can videos be generated?
It natively supports videos of 2–15 seconds at 720P or 1080P resolution, output as 30 fps MP4 files. When choosing, first consider whether the action can be fully expressed within the target duration; for longer stories, split them into multiple short clips and edit them together rather than putting every plot point into a single generation.
How can a short video have multiple shots?
This model natively supports multi-shot storytelling. In the prompt, describe the opening, main action, and ending frame in sequence, clearly specifying the subject, action, and transition relationship for each shot. Each segment should revolve around the same subject and plot, reducing conflicting composition requirements; the number of shots and transition effects are not individually locked, so check whether transitions are natural after generation.
Does it support videos with sound?
wan2.6-i2v natively supports audio-video synchronization and can be used to create short videos with sound. You can specify the sound atmosphere and its relationship to on-screen actions in the prompt, but this is not the same as precise dubbing or voice cloning. Before publishing, still preview the finished video and check the correspondence between audio content, pacing, and visuals.
How do I obtain the generated result after submission?
You can set async=true to submit asynchronously and obtain a task_id, then query the final task status through /wan/tasks. Successful results provide a video link, and the response also defines video dimensions and thumbnail fields. The workflow should first confirm that the task succeeded before proceeding to preview, save, and publish.
