I keep getting a buffering error every time I try to move the head when I have made a change. The help says it is due to insufficient memory, but I have sufficient memory and it happens even for non-intensive effects. See attached pics for specifics.
The second screenshot shows you have an image that is 1918857952 pixes wide. I don't think that's probably true. But can you share more details on your comp size, the image you are trying to put into the comp, etc?
