You'll two cookie cutter FXs, one after the other to get the two round cutouts. Maybe feather the edges a little to make it more realistic.
Bob.
[edit] Always a good idea to put a track of legal black (16,16,16) under any of these things too.You could make it smidge brighter in this case for that 14th coat of wax touch of realism.
use just one cookie cutter , choose circle, set repeat x to 2, this gives you 2 circles, then size it so the two just break and becomes one with little bit of black in the center top and bottom.
Place on the track above your video and set the track compositing for that track to "Multiply (Mask)." Adjust the pan/crop settings for the mask to determine how much of the video you want.
I created this mask in about ten seconds on my photo editor. I created a file at 4x SD video size (so I wouldn't get jaggies if I had to zoom in a lot on the mask). I then filled the entire frame with pure black. I then created a pure white circle. I duplicated that circle and then overlapped the two circles slightly. Finally, I aligned the two circles vertically.
