I have specified to match "contents" for the document size of my movie. But there is extra space at the top. Why is there no crop button? :( I can't find anything that exists in that top portion - I double click there and nothing happens. I guess I could select all the contents, move everything up, and make the document size shorter, which would crop the bottom. But is there any other way? Or is there a way to specify the height and have it take it from the top?
