Video generation by wan/2-5-image-to-video
## Create Task
Use this endpoint to create a new image-to-video generation task.
After submission, use the unified query endpoint to check task progress and retrieve results
::: tip[]
For production use, we recommend providing the `callBackUrl` parameter
so your service can receive completion notifications instead of polling
for task status.
