Wan 2.5 Preview Text-to-Video model can generate high-quality video content based on text descriptions, and can produce videos with durations of 5 seconds and 10 seconds. New audio capabilities: supports automatic dubbing, or you can provide a custom audio file.
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.
