参数
| 参数名 | 描述 | 类型 | 必填 | 枚举值 |
|---|---|---|---|---|
| prompt | Video content description. Maximum 10000 characters. Use double quotes for dialogue: “Hello world!” 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 | 是 | - |
| camera_fixed | Whether to keep the camera fixed during generation. | boolean | 否 | true, false |
| duration | Video duration in seconds (4-12 seconds). | integer | 否 | 4, 5, 6, 7, 8, 9, 10, 11, 12 |
| execution_expires_after | Task expiration time in seconds. | integer | 否 | - |
| generate_audio | Whether to generate audio (speech/sound effects/background music). 1.5 Pro exclusive feature | boolean | 否 | true, false |
| ratio | Aspect ratio of the generated video. | string | 否 | 16:9, 4:3, 1:1, 3:4, 9:16, 21:9, adaptive |
| resolution | Output resolution of the video. | string | 否 | 480p, 720p, 1080p |
| return_last_frame | Whether to return the last frame of the generated video. | boolean | 否 | true, false |
| seed | Random seed for reproducible generation. Use -1 for random. | integer | 否 | - |
| service_tier | Service tier for generation (e.g., default or flex). | string | 否 | 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.

[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-1.5-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.
- bytedance/seedance-2.0-fast-i2v: [Core Function] Seedance 2.0 Fast I2V is a high-speed multimodal video generation model. [Strengths] Fast generation with the multimodal and multi-shot capabilities of the Seedance 2.0 architecture. [Best For] Highly recommended for: rapid prototyping and quick multi-shot video creation. [Limitations] Do NOT use this model for the absolute highest cinematic fidelity (use the standard 2.0 model instead). [Routing] Choose this model when the user emphasizes ‘fast’ or ‘quick’ generation.
- bytedance/seedance-2.0-i2v: [Core Function] Seedance 2.0 I2V is ByteDance’s flagship unified multimodal video generation model. [Strengths] It supports complex mixed references (multiple images, audio clips) and generates up to 15s of multi-shot audio-video output with dual-channel audio. [Best For] Highly recommended for: high-end complex video generation, multi-shot narratives, and mixed-reference cinematic production. [Limitations] Do NOT use this model if you only need a very basic legacy generation without complex references. [Routing] Use this model by default for any complex, multi-reference, or high-fidelity image-to-video tasks.
- bytedance/seedance-2.0-fast-v2v: [Core Function] Seedance 2.0 Fast V2V is a high-speed video-to-video generation model. [Strengths] It offers rapid video transformation capabilities based on the 2.0 architecture. [Best For] Highly recommended for: quick video restyling and fast iterations. [Limitations] Do NOT use this model when absolute maximum visual quality is required (use standard 2.0). [Routing] Use this when speed is the primary concern for video transformations.

[Strengths] It allows powerful editing and stylization of input videos by supporting mixed references (text, images, video, and audio) and producing multi-shot 15s outputs. [Best For] Highly recommended for: complex video-to-video transformations, restyling existing footage, and creating dynamic multi-shot edits. [Limitations] Do NOT use this model for simple still-image generation (use Seedream instead). [Routing] Use this model by default for any video editing or video-to-video generation tasks.
