Alright so here's what i have. I took a video of Me holding a gun pointed at no one in front of a green screen, then had another shot with me being the one where he pointed the gun at. I hung strings from the ceiling to know where to swing and hit the gun that "wasn't there" so it all plays nicely in theory. Yet, when i run it through composite, i'm a bit confused on how exactly i would do this. I tried garbage matting one side like most do with cloning, yet when my hand goes to smack the gun half of it vanishes behind the matte. How would I do this so that you can see my hand, then the gun behind it getting smacked out?

Thanks!

Greenscreen both characters, and place them both in front of a background plate. Otherwise, there will be a ton of labor-intensive masking by hand to isolate your hand from the background.

I already have them both in front of greenscreen and i'm not exactly sure what you mean by just a "background plate", though im assumming u mean adding like a video or picture to the green screen. When i do this though the matte still blocks off my hand from when i go across the gun and swat it down. Also, say i were to do the laber intensive masking, how would i do so?

Sorry, i'm still new at this, yet i have a ton of time on my hands so i'm all up for the crazy masking.

I'm actually not enitely clear on what you are doing, I guess.

A bakcground plate is a background with no actors in it. Say this gun slapping takes place in a kitchen, the backlground plate would be the kitchen with no people in it. Then you add your two characters who were shot in front of the greenscreen, key out the greenscreen, and you've got your two clones in the kitchen.

I'm not sure what matte is blocking your hand, but if both actors are greenscreened, then there shouldn't be any garbage mattes require that would get in the way, unless your hand extends past the edge of the greenscreen on one of them. You should be able to just place them both onto the canvas, and the hand of the top layer ( the clone smacking the gun) will cover the hand holding the gun as it comes across to smack it, then the gun goes flying.

It almost sounds like you are trying a split-screen technique here. This is completely unnecessary with greenscreen, if that is what you are trying. If not, them no worries, its just my confusion.

i think i knpw
u should key the one with the gun, and the other guy, then put the 2nd guy(one that hits the gun away) on the top layer, and mask out part of his hand(you will have to do this frame by frame for a few frames, or a few more depending on how u did it) i really think this should help, sorry if it wasn't clear
