I've been working with still images accompanied by moving text; specifically, 24 and 36 pt., Times New Roman, red. The Vegas text, especially after rendering to AVI, is noticeably uneven in width and soft around the edges. My experiments with a trial version of Nero 8, however, give me MUCH sharper text with no need for adjustments.
I"ve fooled with the "Reduce Interlace Flicker" switch and the text frame size (smaller than 720x480, worse; bigger than 720x480, no better. I WANT Vegas to produce better results than Nero, but, at least in this one area, Nero seems to win hands down.
