Query Task Status
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)
