Masking

I had to mask out some parts in my compositions. The main parts that need masking is when the stencil and the surrounding paint. When the stencil falls off the canvas it needs to take with all the paint that was on it apart from the word ARTS and any surrounding paint.

In order to do this I took the still from paint splatter:

I then started masking out the areas that would not be affected by the stencil falling off:

I just adjusted the masks to subtract and the outside paint splats disappeared. 

I was now left with my stencil that was ready to have the CC page turn applied to it and then it had to be animated so that it came in at the correct time in the composition
