Don’t I have to double then the Main Layer which contains my footage?
I try to describe my project more detailed: I have a skyline of the shore of Tel Aviv, shot from a boat.
I added an Adjustment Layer, with the A Light/Lens Flare Effect, which I use as Explosion.
The Flare should be behind the Skyline, so I added a mask to my Adjustment Layer, which Contains the Flare Effect, to limit it to the space in the frame above the Skyline (the mask has the shape of the Skyline).
Because, the thing was shot on a boat, I tracked the original footage and put the tracking Data on a Null Layer. The Flare Position I attached to the Null Layer’s Position, and I would like to be able to do the same with the Mask on The Adjustment Layer, which is limiting the Flare Effect.
