within an hour of making the mistake of upgrading to vegas 12 I had so many issues with rendering and freezing. I can not understand how the people at Sony couldnt use 10 or so Editors to test their ‘new’ software and found all these issues we lab rats are having. It wony cost sony much to test for a week with REAL editors and then fix the bloody bug and then make your beautiful advertiements about your new vegas 12…so sick of this upgrading problems with all these software giants who cant seem to get it right….
