About this model
SD 2.0 全能参考可使用参考图像、视频和音频生成具有视觉一致性的视频。不同于只将单张图像制作成动画的标准imagen a vídeo，全能参考会将你上传的素材用作创作引导——在保持角色身份、视觉风格和场景连续性的同时生成新视频。单次请求可组合最多 9 张图像、3 个视频片段和 3 个音频文件。在prompt中使用 @image1、@video1、@audio1 语法，可精确控制每个参考素材如何影响生成的视频。

Configuration schema
| Parameter | Type | Description | Default |
|---|---|---|---|
| Prompt | string | Video description. Use @image1…@image9 to reference images, @video1…@video3 for videos, @audio1…@audio3 for audio. To use a character sheet, reference it with @character:<request_id> (from a completed Seedance 2 Character generation). To use a trained Omni Reference character, reference it with @omni-character:<character_id> where character_id is the value returned by Omni Reference Train Character (e.g. char_1775422630065_4vbana). Both methods can be combined in the same prompt. Multiple characters are supported. Example: '@omni-character:char_1775422630065_4vbana walking through a neon-lit city at night'. | @image1 is the main character reference. A person walking on the beach at sunset, cinematic lighting |
| Imagen URL | array | 最多 9 个参考imagen URL（JPEG/PNG/WebP）。第 N 张imagen对应prompt中的 @imageN。 | https://d3adwkbyhxyrtq.cloudfront.net/webassets/videomodels/seedance-v2.0-omni-reference.png |
| 参考Vídeo URL | array | 最多 3 个参考vídeo片段 URL（MP4，每个最长 15 秒）。第 N 个vídeo对应prompt中的 @videoN。 | undefined |
| 参考Audio URL | array | Up to 3 reference audio clip URLs (MP3/WAV, total max 15s). Each Nth audio corresponds to @audioN in the prompt. | undefined |
| Relación de aspecto | Enum (6 options) | salidavídeo的relación de aspecto。 | 16:9 |
| Calidad | Enum (2 options) | Generation quality. 'high' uses the standard model ($0.30/sec output + $0.09/sec per input video second). 'basic' uses the fast model (~2x speed, $0.21/sec output + $0.063/sec per input video second). Video reference inputs incur an additional 30% surcharge based on their combined duration. | high |
| Duración (segundos)（秒） | int | Video duration in seconds (4–15). | 5 |

Frequently asked
imagen a vídeo会把你的图像作为实际第一帧并将其制作成动画。全能参考会将图像、视频和音频作为创作引导——模型生成与参考素材在视觉上匹配的新场景，而不会将它们作为实际帧使用。它还支持imagen a vídeo不支持的视频和音频参考。
使用 @image1、@image2 等，按其在 images_list 中的位置引用图像。使用 @video1、@video2，按其在 video_files 中的位置引用视频。使用 @audio1、@audio2，按其在 audio_files 中的位置引用音频。如果不使用 @ 语法，系统会自动将第一个参考素材作为主要参考。
不需要。所有参考数组都是可选的。你可以只提供图像、只提供视频、只提供音频，或任意组合。仅使用文本prompt也有效。
图像：JPEG、PNG 或 WebP（最多 9 个）。视频：仅支持 MP4，每个最长 15 秒（最多 3 个）。音频：MP3、WAV 或其他常见格式，总时长最长 15 秒（最多 3 个文件）。所有 URL 必须可公开访问。
费用 =（费率 × salida时长）+（0.3 × 费率 × entrada视频总时长）。'high' 质量：salida $0.30/sec。'basic' 质量：salida $0.21/sec。如果提供 video_files，则按合计entrada视频时长的每一秒额外收取 30% 附加费。示例：5s salida（high）+ 两个 5s entrada视频 = 5×$0.30 + 10×$0.09 = $1.50 + $0.90 = $2.40。
'high' 使用标准模型以获得最佳salida质量。'basic' 使用快速模型，生成速度约为 2 倍，但质量略有降低——适合快速迭代和预览。未包含 quality 字段的现有请求默认使用 'high'。
16:9、9:16、1:1、4:3、3:4 和 21:9。默认值为 16:9。
