Scissor Jitter to Isadora

[laobra]

Hey everybody.

I'm searching some actor or procedure that allow me to have one part of an image ( video or picture ) in a projector, and another part of the same  image in another projector. If someone use Jitter, the closer operation that produce this effect is the objet Scissor that allow  you to separate a stage( matrix)  into evenly spaced sub stages. 

Thanks a lot
