Hey Angelo Thanks for your input.
I’m so desperate ! I’m convinced that Cineform is the problem, however,I have over 50 hrs of my project converted to avi. At this point I have no plan B, I got have it edited. I was trying to find a way to downgrade from sony vegas 10 to vegas 9, can’t find a way to do that, in fact, I don’t think it is possible. It seems that cineform is sony vegas 9 friendly. I was also thinking of switching to adobe premiere cs5, not sure if i will have the same problem with cineform and Adobe. I am really upset with this situation becouse I have many hours already edited and cannot give up now. This Cineform is a complete night mare !!! I am considering start my project from the beginning all over again but I got be sure that since my files are under cineform conversion I don’t want to play this game again and don’t win . If you have any idea please help me man !
