The base clip should probably be the darker clip and the overlay clip should be the lighter clip. Then change the opacity to try and find what you are looking for. opacity=1 might even work.

Ok, that gives me some things to experiment with. By "base clip", do you mean cap1 or cap2 in the script?

The base clip is the "bottom"clip in overlay. The overlay clip is the clip put on top of the base clip. the base clip is always the first clip entered into the overlay filter. So the base clip in the filter below should be your darkest clip, regardless of whether it's cap1 or cap2. If they are backwards, just flip them around.

Overlay(BASE clip,overlay clip,mode="luma",opacity=0.5)
