i think i found a better - photoshop-like :) - solution..
there is an example of this solution attached to this mail:

the pix_multiply function just works for pix.. that was my problem.
you can't multiply a movie with a "normal" rectangle-object this way..

my workaround:

i took a black image in the same dimensions as my movie-material and 
used pix_rectangle to draw a rectangle on this black dummy-image.

so i could use pix_multiply to combine the movie with the black-image i 
painted the rectangle on..


this works quite great for making visuals :D


have fun !
