Hello! In this asset I simply moved the alpha mask into a separate file for convenience. The package contains two files. In one there is a matte, alpha channel, a mask, I don’t know what to call it more precisely (it is in the rgb channel), and in the second file there is a color, beauty pass render (as it is in the preview). Load both files into your compositing and post-processing software. Convert any channel from video with mask to alpha channel for the video with color. Perhaps you should also do the premultiply operation after that. Merge the resulting layer with normal overlay on the background.
