I was using Vegas 10 and I have all the videos and the .veg file saved on a flash drive. I just reformatted and installed Windows 7 64 bit with Vegas 11. It renders now without the Low Memory error. I rendered with the “Video for Windows (.avi)” codec and the NTSC DV template but through out the movie there was 1 clip where the video is black and you can only hear sound. I tried to render again with WMV 5 mbps HD 720 template and there is like 6 minutes of just black.
