Opacity is ok. What is strange is that I rendered the video first as as AVI after using Excalibur’s multi-cam wizard and it only took about 3 hours. I then proceeded to edit the AVI down, due to total length. Added a 15 second, not 45 as stated in my original post, to the beginning and scrolling credits at the end. I then proceeded to render as MPEG-2 and left it all night beginning at 11pm and at 7pm it was only 11% or at about the 20 minute mark. I have not changed anything. This is so puzzling. I have been using VEGAS since 2.0 and have never had this problem.
