When rendering preview files In CS5, on a sequence with a 'Desktop' editing mode (set to 1920x800), first of all it renders fine, however on closing the programme and re-opening, the preview files are unlinked (ie shows red), and when I re-render them, it squashes a 1920x1080 preview (with black borders) into the smaller frame size - any ideas?
(The original footage is 1920x1080)
The export is actually fine as I found out when I tried to export frame for each of these and they were exactly the same! It is just not helpful when editing...
