I am having a problem viewing source media in the composite window of Boris Graffiti 4. I open an empty event in Sony Vegas 4, then apply Boris Graffiti as the video effect, and everything opens up fine. However, I do not see the video I am trying to title over in the composite window, so I have to try and make all adjustments by guessing, then apply the effect, exit Boris, check how it looks in Vegas, then re-enter Boris to make another adjustment. There has got to be a way to preview in the composite window? Any suggestions?
