最近很火的AI视频，30秒展现一个人的一生，我们来看一下制作流程

包含以下知识点

• 安装ComfyUI + AnimeDiff插件
• 使用Prompt travel描述视频画面

1. 加载工作流文件

在BatchPromptSchedule这个节点里描述出画面的内容，前面的数字代表对应的帧数

2. 安装缺失的node组件

第一次载入这个工作流之后，ComfyUI可能会提示有node组件未被发现，我们需要通过ComfyUI manager安装，它会自动找到缺失的组件并下载安装（！！需要网络通畅）。

点击ComfyUI Manager按钮打开组件管理

再点击Install Missing Custom Nodes安装组件

安装完成后要重启ComfyUI才能完成载入刚才缺失的组件。

如果网络状态不好，可能会导致下载组件失败，需要多试几次

3. 选择一个检查点模型

下载模型DreamShaper 8。

将safetensors文件放入文件夹ComfyUI > models > checkpoints中。

刷新浏览器标签页。 找到节点“Load Checkpoint”。点击ckpt_name下拉菜单，选择dreamshaper_8模型。

4. 选择一个VAE

下载VAE。将文件放入文件夹ComfyUI > models > vae中。

刷新浏览器页面。

在Load VAE节点中，选择刚刚下载的文件。

5. 选择AnimateDiff动作模块

下载 AnimateDiff v1.5 v2 动作模型。

将其放入文件夹 ComfyUI > custom_nodes > ComfyUI-AnimateDiff-Evolved > models 中。

刷新浏览器页面。

在AnimateDiff Loader节点中，在model_name下拉菜单中选择mm_sd_v15_v2.ckpt。

6. 下载负向嵌入

这个工作流程使用了BadDream负面嵌入在负面提示中。

它是为Dream Shaper模型训练的负面嵌入。

下载BadDream嵌入文件。

将文件放入ComfyUI > models > embeddings目录中。

7. 生成视频

点击“Queue Prompt”开始生成视频。

进度条将出现在KSampler节点上。

当完成时，将在视频合并节点中看到视频出现。
