## Query Task Status
After submitting a task, use the unified query endpoint to check
progress and retrieve results:
Learn how to query task status and retrieve generation results
::: tip[]
In production environments, it is recommended to use the callBackUrl
parameter to receive automatic notifications upon completion, rather
than polling the status API.
:::
> **Note**
>
> * **Image-to-Video (First Frame)**, **Image-to-Video (First & Last
Frames)**, and **Multimodal Reference-to-Video** (including reference
images, videos, and audio) are three mutually exclusive scenarios and
**cannot be used simultaneously**.
> * Multimodal Reference-to-Video can indirectly achieve a "First/Last
Frame + Multimodal Reference" effect by specifying reference images as
the first or last frame via prompts. If you need to strictly guarantee
that the first and last frames are identical to the specified images,
**prioritize using Image-to-Video (First & Last Frames)**
## Key Features
Generate videos directly from text descriptions without input images
Animate static images with 0-2 input images support
Advanced camera movement with optional lens locking for stable shots
Optional audio generation for enhanced video content
