Have you tested mixing the PGM out with DVIO card configured as output?
If you pull the T-bar to over 60% down, you start to get very interesting ‘ghost’ effect in real time. The delay caused by conversion to DV format will add softness which looks really interesting. If your camera is on pedestal, everything that is stable looks normal, but everything that moves is soft. Depending on the position of T-bar, it takes a moment before stopped object becomes ‘solid’.
