Parameters
| Name | Description | Type | Required | Enums |
|---|---|---|---|---|
| prompt | Description of the desired output. Maximum 10000 characters. Recommended prompt length: under 1000 words. Lengthy text will lead to scattered information, and the model may ignore details and only focus on key points, resulting in missing elements in the generated video. | string | Yes | - |
| camera_fixed | Whether to keep the camera fixed during generation. | boolean | No | true, false |
| duration | Duration of the generated video in seconds. | integer | No | 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 |
| execution_expires_after | Task expiration time in seconds. | integer | No | - |
| frames | Total number of frames to generate. | integer | No | - |
| ratio | Aspect ratio of the generated video. | string | No | 16:9, 4:3, 1:1, 3:4, 9:16, 21:9, adaptive |
| resolution | Output resolution of the video. | string | No | 480p, 720p, 1080p |
| return_last_frame | Whether to return the last frame of the generated video. | boolean | No | true, false |
| seed | Random seed for reproducible generation. Use -1 for random. | integer | No | - |
| service_tier | Service tier for generation (e.g., default or flex). | string | No | default, flex |

- bytedance/seedance-1.0-pro-fast-t2v: [Core Function] Seedance 1.0 Pro Fast T2V is an older generation text-to-video model. [Strengths] Known for its rapid generation pipeline and robust performance on standard commercial prompts. Maintained for backward compatibility. [Best For] Existing legacy integrations that require the specific speed/cost tradeoff of this older model. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Seedance 1.5 Pro T2V.
- bytedance/seedance-1.5-pro-t2v: [Core Function] Seedance 1.5 Pro T2V is a joint audio-video text-to-video generation model. [Strengths] It accurately follows complex text instructions to generate high-quality video with synchronized audio. [Best For] Highly recommended for: standard text-to-video generation where strict prompt adherence and audio are required. [Limitations] Do NOT use this model if you need the advanced multi-shot or multimodal reference capabilities of the 2.0 architecture. [Routing] Use this model by default for ByteDance text-to-video tasks.
- bytedance/seedance-1.0-pro-fast-i2v: [Core Function] Seedance 1.0 Pro Fast I2V is an older generation image-to-video model. [Strengths] Known for its rapid generation pipeline and robust performance on standard commercial prompts. Maintained for backward compatibility. [Best For] Existing legacy integrations that require the specific speed/cost tradeoff of this older model. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Seedance 2.0 I2V.
- bytedance/seedance-1.0-pro-i2v: [Core Function] Seedance 1.0 Pro I2V is an older generation image-to-video model. [Strengths] Known for its rapid generation pipeline and robust performance on standard commercial prompts. Maintained for backward compatibility. [Best For] Existing legacy integrations and workflows that strictly depend on this specific model version’s quirks. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Seedance 2.0 I2V.
- bytedance/seedance-1.5-pro-i2v: [Core Function] Seedance 1.5 Pro I2V is a joint audio-video image-to-video model. [Strengths] It accurately follows complex instructions to animate a single image with synchronized audio. [Best For] Recommended for: standard image animation tasks where 2.0’s multi-reference capabilities are not required. [Limitations] Lacks the robust multi-shot and multi-image reference features of 2.0. [Routing] Use this if the user specifically requests the 1.5 architecture, otherwise default to 2.0.
