hmmmm,
5000 black frames.......
been there, seen that.
Is there any amount of "black" before the first image appears?
It could be that the system is trying to create the appropriate number of "almost empty" frames to fill the time. lets do the math... 32 tracks, 0 points, at 30k, that's alot of blank frames.
If so, it is likely that increasing the "minimum number of points" in the projector settings will greatly reduce the number of black frames being produced. However, it will potentially alter the displayed image if it changes the number of points being displayed.
Getting rid of that pause time where no images are displayed would be a better soloution, if this is the case.
Or place a black frame in there with a bunch of points, 1000pts (blank), that goes away as the first image is displayed. that seems to work best for me.
give it a whirl, see what happens.
