Lua script that adds an 8 point polygon mask/matte filter for cropping away a portion of the image or for isolating a portion of the image when your greenscreen backdrop is smaller than the image frame.
Install the filter-polymask.lua script file.
Add the Polymask filter to your source.
I know you can use image as mask. But I would like to use animation as mask. And I don't know how to set this up with current tool set. Do I miss something?
