Layers don't be synchronize withe the same cue
In my project I use tow projectors and I project the same image in the same time in this tow projector which are superposed (to have more luminosity..)
So, do that I simply duplicate layer and move one in the first projector and the other layer to the seconde one in the second projector. But some time happen, when the cue come, they don't start in the same time and so I have and my tow images are completely unsynchronized (about 0.5seconde). And into a sceen of 9,6m / 5m it's a big problem in live!
any idea why it's happening, Or other idea how to project the same thinks in tow different output without using mad mapper, and I need to map differently this tow projectors so I can simply spleet one output...
