使用FFMPEG的乘法混合模式添加绿色叠加

Question

我目前正在开发一个需要视频编辑的项目。 这里我正在使用ffmpeg，它运行得很好，除了1个过滤器。 每个视频都应该使用Photoshop多重混合模式进行叠加。 我正在使用ffmpeg混合模式，但遗憾的是视频会在屏幕截图中看到绿色叠加。

原始图像

用ffmpeg 编辑

我想要实现的目标

这与我工作的模式有什么关系吗？ 以下是我目前的代码

#!/bin/bash
vagrant ssh -c "./ffmpeg \
-i /vagrant/public/uploads/video/bw_RzWecVH02p.avi -i /vagrant/public/img/red_ellipse.png \
-filter_complex "blend=all_mode='multiply'" \
/vagrant/public/uploads/video/overlay_RzWecVH02p.mp4"

这是我的ffmpeg输出
