I currently use Vegas Movie Studio Platinum to edit product videos at work. When rendering HD files vegas crashes. I guess it is a common problem with 32 bit operating systems and HD videos. Sony had told me vegas pro on a 64 bit os would allow me to utilize up to 4 gb of ram, while a 32 bit os will only let me utilize 2 gigs. I saw that vegas platinum can run on a 64 bit oS, but will it run like a true 64 bit program? or will it only be able to use 2 gigs of ram and cause the same issues?
