There have been other reports of render files getting "lost". Nothing to do about it, except re-render. You might try trashing your prefs (Final Cut Rescue 6 is a neat helper app) Also, you might trying to reset your scratch disks (telling FCP where to save the render files) I guess it doesn't help much to know you are not alone. regards, sb On Jul 5, 2007, at 4:50 PM, carlian wrote: > I am using the latest version of FCP on an intel Mac Desktop. > > Despite rendering and saving before closing a Project, the next > time I open it much of the content requires re-rendering.
