I have al my clips loaded into the timeline, they are all from the same shoot, same file format, etc. However some wont show when I make them visable to scrub through them, just shows black, also when I make cuts and move them up to my working area they dont show. Im not sure what the issue is. When I select view frame, it shows all the frams of the clips but I am unable to view them when I play the sequesnce. I am running 5.5.
