有没有想过如何为你的 YouTube或者其他视频频道创建类似下面的会说话的AI头像？这种类型的头像非常适合想要开设不露脸 YouTube 频道的人。并且这种简单的动效用免费的工具就可以轻松搞定。
那么接下来就看看如何实现。
我们需要用到两个工具+一个素材：
- 工具1：AI绘图工具。类似的工具非常多，这里我推荐playground，因为免费，并且可以编辑图片，简单易用。
- 工具2：剪映，海外版的叫capcut，用来编辑视频。
- 素材：一个说话的嘴巴的绿幕视频素材。
以上都是免费的。
Step1 ：AI绘图
我们用playground来绘图，
playground地址：https://playground.com/
进入之后，我们点击右上角的create
然后输入prompt。
prompt可以参考这个：geeky man, staring directly into the camara, straight face and body,centrre of room, behind a desk, hacker, futuristic,cinematic
在filter选择图片的风格。
比如我选择Counterfeit V1这个风格。
然后点击生成即可。AI就会帮我们生成对应的图片。
另外，关于playground页面里的其他配置项这次用不上，详细的使用说明之前有介绍过，需要的话可以看以前的视频介绍。

Step2：编辑图片
在生成的图片里面，选择一张你喜欢的，然后点击下图中红框里的图标，即edit in canvas
接下来我们要把图片里的嘴巴去除掉。
点击object eraser
用画笔把嘴巴部分涂抹上，然后点击erase
稍等一会，就发现嘴巴已经被清除掉了，然后我们把图片下载下来即可。
Step3：加入动效
最后一步，就是要在没有嘴巴的图片上，给它加上一个动态的嘴巴。这里我们用剪映搞定。
首先我们准备好一个绿幕的素材（可以直接下载）
在剪映使用绿幕素材的方法之前有介绍过，链接如下。

我们打开剪映，把素材上传上去，然后按如下图的操作即可
最后我们把嘴巴的大小调整好，放到图片中对应的位置即可。
最后导出视频，就完成了全部的操作。你就可以把视频应用在你的频道里了。
