Hi everyone I have a production that I am working on that has a number of items of scenic projection. The image below shows the set with the white areas being the sections of set I would like to project on.




For the show to fully work as the director wants I need to be able to cross fade between 2 videos on each section of the set (white areas of the image) as well as being able to project 1 video across all of the scenic elements of the set at the same time. So I am looking for some advice on the best way to achieve multiple masked areas as well as being as flexible with content selection and placement I would make a master mask that sat on top of everything and simple put mixes behind but on either side of the set the scenic elements are at an angle that would makes this impossible (I think).

Any general advice about compound masks and masking in general would be greatly appreciated and will give me a better understanding of how to approach this setup.

I will be projecting with a pair of stacked Barco HD20's for reference, if more info is needed let me know.

Cheers
Steve
