19 = absolute difference: abs(dest-src)*gfx_a (only valid when using YUV colorspaces)
It was a lot of trial and error, had to invert my monitor colors, then tweak the code until the video looked normal again.

I figured out a screen/lighten blend, not exactly sure which it is. Works for the handwritten text thing I wanted to do and some other stuff (see video).
// JT: lighten/screen overlay
// black is removed. use after inverting color
img1=0;
img2=input_track(0);
gfx_blit(img2);
gfx_mode = 1;
gfx_blit(img1,0);
