Video inside a non-rectangular, moving outline? AnimPro2

I’m trying to figure out a way in Pro2 to have video appear in a cartoon character’s “thought balloon”, preferably a non-static shape. I’m familiar with importing video and using the Cutter module to eliminate what’s inside the mask area, but how do I do the opposite and only show what’s inside the mask area?

Thank you!

Click on the yellow square on the left of the cutter module and tick the “inverted” box.

Wow, so simple! Thank you!!
