So I have a lot of masking key frames(over 1000) and I need to change the Feather type and Percentage of each one. Since there doesn't seem to a way to do a global change inside Vegas, I thought I would look into scripting. I found classes for changing/retrieving pretty much everything but frame masks.

Is it possible to do this and if so, is there an undocumented class or is accessing the video mask hidden in one of the Effects or CustomData classes?
