The scene consists in having two actors, flying in mid air, fighting each other with swords(IN MID AIR!) while the camera makes some really wild movements around them(rotation from x-axis and y axis, full rotations, a bit like the scenes in the matrix but from upside down too)
my problem is that i filmed them as 2 distinct layers. now in compositing i want to make a single shot(make the respective keying for one actor, for the other and for the background, as well inserting a flare blow and sparks in the middle of the two actor layers and dust and such). The problem is that i have no clue on how to say to the compositing program i´m using(AE5.5) that in this frame the actor-A is the 1st layer on screen(or the actor on the back) while the Actor-B(the actor in front of the camera, inheriting visibility to actor-A) and in the next seconds switch theyre respective orders(Actor-A to front and actor b to back). How can i do that? it might be simple but i got no clue on how to do it, since im new to composite rotating cameras.
i´ll keep trying to get a way to do it, but if u can please aid me.
