I'm trying to create a multiple monitor effect where I have 3 videos playing on the screen in a multiple PIP effect. I've used a photo of three monitors and have used the pen tool to create transparency zones on each of the monitors, and then have sized video in other layers to fit in the screens.
Here's what I don't get. Each of these screens becomes its own mask, the first one is add and invert, the second is subtract, but I can't get the third mask to be transparent at the same time as the other two.
Is there some way to merge all three masks into one?
You're almost there -- just play around with the mask modes until you get the three holes you want. No big deal.
For added realism, duplicate the layer and fiddle with the masks until only the glass on the screens shows. Make it the uppermost layer, and use one of the blending modes like Screen or Overlay on it -- it'll go over the pieces of video you put in the TVs . And don't forget that playing with this layer's opacity can help you get the right look, too.
