I'm using HD Platinum 11, and want to use two different clips on each half of the screen.

I created a layer above each of the video clips, and made them compositing parents for my mask layers, and the set the composite modes to Multiply (mask). I created a .png file I created that is one-half transparent, one-half black, exactly 1920x1080 pixels large. I put one version on the first mask layer, and the reverse image version on the second mask layer.

I can see either one if I mute the other tracks, but I can't see both together. When I activate the upper most tracks, it blacks out the lower one.

Is there an easier way to do a split screen affect?

Here's a screen shot of my settings:
