I Design Scenery for TV. We have been successful using still images that are cut up into 3 sections, sticking them on a thumbdrive with each monitor showing the properly placed section of the photo. I looks great just like a window.
Of course now people are asking for a cheap way to run video, and even masking off an image causes a syncing of the action problem. Is there a videocard or some other technique that would allow me to scale a video file in portrait mode?
