Hmm…I just had something really odd happen when I went to render my masterpiece. While the score bug looks great in the preview window in Vegas (White writing with one block of blue and one block of black background), when I render the footage, the white text disappears completely and the blue and black blocks move to different locations on the screen.
Since I have to look at the preview window to line everything up when editing, what is one to do if rendering causes everything to move around?
