Bytedance - Seedance 1.5 Pro
Generate high-quality videos from text or images with Seedance 1.5 Pro’s advanced AI capabilities
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
For production use, we recommend using the
callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.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
Audio Generation: Enabling the
generate_audio feature will increase the generation cost. Use it when audio is essential for your video content.Related Resources
