I have a black background with white text, how can I do an hightlighter effect so it turns white and the letters turn black?
I achieved this more or less with 2 layers
Layer 1: white solid
Layer 2: the image with the text parented to layer 1

I just stretch the white solid so it covers the text with keyframes, and I use the “Difference squared” mode on the white solid layer but this causes that the image becomes a bit too dark as you can see. Any ideas?
