Query Task Status#

After submitting a task, use the unified query endpoint to check progress and retrieve results:
Get Task Details
Learn how to query task status and retrieve generation results
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#

Text-to-Video
Generate videos directly from text descriptions without input images
Image-to-Video
Animate static images with 0-2 input images support
Dynamic Camera
Advanced camera movement with optional lens locking for stable shots
Audio Generation
Optional audio generation for enhanced video content
