Creating Multiple Masks in the same video

[Alittlebitslow]

Can I open the mask effect and create multiple masks in the same scene. I need to mask out a window, but the window is a multi-pane, divided window, so I need to create about 6 masked rectangles (or polygon shapes possibly).

I know how to do 1 mask, but how do I keep adding more masks for the same video?

Add the first mask (video effects, small plus icon "Add effect mask") and then the desired video effect on top, e.g. blur. The blur effect will only be visible within the first mask.

Then add mask #2 (click the small plus icon again) and add another effect #2. Like before, effect #2 will only be visible in mask #2. You can repeat this as often as you need it.
