As far as I know the subject title is the best way to describe this particular problem. At the moment I have been trying to animate clips in terms of movement and for the most part I have followed the directions provided in the Panorama tutorial. However, despite key-framing the movements and evidently seeing the changes as I move the marker from left to right in the composite window, nothing at all (in terms of changes) is displayed in the project window. Would anyone know what this problem could be attributed to? I'm using Xubuntu 9.04. Apologies if this topic has been addressed before on the forums, but I had googled the issue in advance and had found nothing of relevance.

At the top of the Composite panel, did you set "with track" to "Black?"
