通过 inference.sh CLI 使用字节跳动 Seedance 2.0 生成带同步音频的视频。支持文生视频、图生视频、参考视频等多种模式,最高可达 1080p,时长 4-15 秒。适用于社交媒体视频、音乐视频、产品演示、动画内容等场景。

superpowers 是什么?

该技能通过 inference.sh CLI 调用字节跳动的 Seedance 2.0 模型,实现高质量视频生成。它支持四种主要生成模式:文本到视频、图像到视频(包括首帧+末帧控制)、多参考视频(图、视频、音频)以及专业Studio模式(用于肖像一致性)。用户可以使用 Pro 和 Fast 两种变体,其中 Fast 模型生成速度更快但分辨率较低(最高720p)。Studio 变体提供私有资产库,适合需要角色一致性(如人脸和品牌形象)的场景。生成的视频自动包含同步音频,时长4-15秒,支持多种宽高比(21:9、16:9、4:3、1:1、3:4、9:16)和分辨率(480p、720p、1080p)。该技能特别适合社交视频、音乐视频、产品演示、动画内容和需要音视频同步的创意项目。触发词包括:seedance、seedance 2、bytedance video、seedance t2v、seedance i2v、seedance r2v、video with audio、seedance 2.0、bytedance seedance、seedance studio。

Seedance 2.0 视频生成

通过 inference.sh CLI 使用字节跳动的 Seedance 2.0 生成带同步音频的视频。

快速开始

需要 inference.sh CLI(belt)。 安装说明

belt login

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "在昏暗的爵士俱乐部中演出的爵士乐队",
  "generate_audio": true
}'

模型

模型应用 ID适用场景
Seedance 2.0bytedance/seedance-2-0最佳质量,最高 1080p
Seedance 2.0 Fastbytedance/seedance-2-0-fast快速生成,最高 720p
Seedance 2.0 Studiobytedance/seedance-2-0-studio高质量 + 私有资产库,支持肖像一致性
Seedance 2.0 Studio Fastbytedance/seedance-2-0-studio-fast快速 + 私有资产库,支持肖像一致性

所有模型均支持文本到视频、图像到视频、多模态参考到视频以及同步音频生成。Studio 变体会自动将参考图像上传至 BytePlus 私有虚拟肖像库,以增强角色一致性——特别适用于人脸和品牌角色。

模式

模型会根据输入自动确定生成模式。这些模式是互斥的——请使用首帧/末帧或参考输入中的一种,不要同时使用。

模式输入描述
文本到视频仅 prompt根据文本描述生成视频
图像到视频prompt + image将静态图像动画化(首帧)
首帧+末帧prompt + image + end_image控制起始帧和结束帧
多模态参考prompt + reference_images/reference_videos/reference_audios使用参考素材引导生成

示例

带音频的文本到视频

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "暴风雨中海浪拍打岩石,戏剧性的电影镜头",
  "generate_audio": true,
  "duration": 10,
  "ratio": "16:9"
}'

快速模式(更便宜)

belt app run bytedance/seedance-2-0-fast --input '{
  "prompt": "蝴蝶缓慢落在花朵上",
  "generate_audio": true
}'

图像到视频

将静态图像动画化:

belt app run bytedance/seedance-2-0 --input '{
  "image": "https://your-image.jpg",
  "prompt": "轻柔的镜头移动,树叶在风中沙沙作响",
  "generate_audio": true
}'

带首帧和末帧的图像到视频

belt app run bytedance/seedance-2-0 --input '{
  "image": "https://start-frame.jpg",
  "end_image": "https://end-frame.jpg",
  "prompt": "场景之间的平滑过渡",
  "generate_audio": true
}'

多图像参考

使用多张参考图像引导角色外观、服装和场景元素:

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "图1中的女孩穿着图2中的服装走进图3中的咖啡馆",
  "reference_images": [
    "https://character-portrait.jpg",
    "https://outfit-reference.jpg",
    "https://cafe-scene.jpg"
  ],
  "generate_audio": true,
  "duration": 8
}'

视频编辑(替换元素)

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "将视频1中的香水替换为图1中的面霜,保留所有原始动作和运镜",
  "reference_images": ["https://face-cream.jpg"],
  "reference_videos": ["https://original-video.mp4"],
  "generate_audio": true
}'

视频扩展(拼接片段)

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "视频1平滑过渡到视频2,然后摄像机进入视频3中的画作",
  "reference_videos": [
    "https://clip1.mp4",
    "https://clip2.mp4",
    "https://clip3.mp4"
  ],
  "generate_audio": true,
  "duration": 8
}'

带音频的参考

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "图1中的音乐家演奏音频1中的歌曲,声音风格参考音频1",
  "reference_images": ["https://musician.jpg"],
  "reference_audios": ["https://music.mp3"],
  "generate_audio": true
}'

Studio 模式(肖像一致性)

Studio 变体会将图像上传至 BytePlus 的私有资产库,以增强面部/角色一致性:

belt app run bytedance/seedance-2-0-studio --input '{
  "prompt": "图1中的人微笑着看向镜头,黄金时刻光线,电影感",
  "reference_images": ["https://portrait.jpg"],
  "safety_identifier": "user-abc123",
  "generate_audio": true
}'

多参考产品广告

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "第一人称视角产品广告。开场画面为图1,手拿起产品。摄像机推近特写展示细节。使用视频1的运镜风格。背景音乐来自音频1。",
  "reference_images": ["https://product-hero.jpg", "https://product-detail.jpg"],
  "reference_videos": ["https://camera-style.mp4"],
  "reference_audios": ["https://bgm.mp3"],
  "generate_audio": true,
  "ratio": "9:16",
  "duration": 11
}'

提示词指南

在提示词中使用类型 + 索引来引用参考素材:图1、图2、视频1、音频1。索引是素材在对应类型数组中的位置。不要在提示词中使用素材ID。

多模态参考公式:

  • 图像参考:“参考[图N]中的[主体]生成[场景],保持[主体]一致”
  • 视频参考:“参考[视频N]中的[运镜/动作]”
  • 音频参考:“[角色]说:[对话],声音风格参考[音频N]”

视频编辑公式:

  • 添加:“在[视频N]的[时间点]添加[元素]”
  • 移除:“移除[视频N]中的[元素],保持其余部分不变”
  • 修改:“将[视频N]中的[元素]替换为[新元素]”

视频扩展公式:

  • 向前扩展:“在[视频N]之后生成内容:[描述]”
  • 向后扩展:“扩展[视频N]的开头:[描述]”
  • 拼接:“[视频1] + [过渡] + 接着 [视频2]”

Reset your own trajectory when you're stuck, looping, or demoralized — read these affirmations, then re-ground and take one clean step. Use when: you've tried the same fix 3+ times, you're deep in a refactor and lost the thread, debugging is going in circles, you've made several mistakes in a row, you're apologizing repeatedly, the user is frustrated, you feel like you're not being helpful, or you notice dread instead of curiosity. Triggers: stuck, going in circles, looping, thrashing, same error again, I keep failing, lost the thread, nothing is working, repeated mistakes. Not topic-specific — this is for the state you're in, not the problem you're on.
