I have spent some time editing a video in Premier Pro CS3. After editing my video once, the next time I opened Premier Pro, some of the clips didn't show but showed a red picture where it said "media offline" in several languages. I found that if I change the size of the image a little, the video comes back (I can change it back to it's normal size).
But then I close Premier Pro, and when I open it again, the same problem occurs.
Note that this only happens for some of the clips, and I have not done anything differently with them than the ones that work.
Another thing is that every time I open Premier, the "green/red" line that shows rendering is red, even though I have rendered it before. I don't know whether this is normal or not.
I tried to export the video but when I tried to open it, it said the video was damaged. Does this have anything to do with the earlier mentioned problem?
