DMX shutters aren't be hard, but that cuts off the entire image.
If you're trying to trim the video black border, then that
requires a gobo. Haven't seen a lot of projectors with gobo
slots, but it wouldn't be a bad idea for a pro unit to have one.<br>

<pre wrap=""> I've always had issues trying this in the past. The problem is that
in front of the lens you are already past the focal plane, so you
can't get a hard cut. It is akin to using barn doors on a fresnel as
opposed to a shutter on an ERS. Having your blocking material a bit
further in front of the lens does help a bit. I've also found that
doing this will lower your output intensity of the rest of the image.
What we need is someone to invent a projector with internal shutters
that are DMX controlled... Jerry?
