Unfortunately Vegas is failing me again when it comes to projects with lots of clips. I'm starting the editing of a corporate training video that has 611 XDCAM files. I'm having various crashing issues during editing as well as clips switching bins and other strangeness with project media management. Clips switching bins can be a nightmare when working with lots of files. I really did not want to edit this one in Premiere CS6 but off I go. Vegas has never been up to the task of editing projects with lots of files and I guess it never will be.
