I'm really hoping that I can explain my situation and you might be able to explain to me what's going on. I have about 25 hours of HD footage shot on the HVX with a FS100. All of it was shot properly because we checked it on the camera ofter shooting and viewed it through the P2 Import window of FCP every day after shooting and dl'ing onto hard drives. Now I'm finally ready to edit and when I try to import I get the red exclamation point. When I hover over it, the message states "Error:Unknown". It seems like it's the spanned clips that are giving me the problem. The others import just fine. I have the raw footage (copied CONTENTS and LASTCLIP) on 4 drives that I want to use as backup drives. I just got 2TBs of drive to import into and work from. Before shooting, I never had any of these problems importing with tests. Did I forget something along the way?
