MLT 框架。使用模糊进行滑动过渡

Question

需要从上到下滑动两个视频剪辑之间的过渡并添加模糊效果：

https://www.dropbox.com/s/epavjs1zbo12hc7/test%20down%20transition.mp4?dl=0

melt 1.mp4 2.mp4 -mix 30 -mixer affine transition.geometry="0=0/0:100%x100%;74=-100/-100:120%x120%;75=-60/-60:110%x110%;149=0/0:110%x110%;150=0/-60:110%x110%;224=-60/0:110%x110%"

无法在 mlt 网站上改进任何带有转换的示例...
