I was just wondering what FCP actually does when it's "Writing Video..."? First I rendered my project, which took about 8 hours, but then it started writing video, and this has now gone for about 3-4 hours, and it doesn't seem to be anywhere near finished. And why doesn't it just do it once? When i finished rendering I got a "Writing Video..." dialog, that got to 100%, leading me to assuming that I was done, but then it started again, and again, and it still goes. Just wondering what's actually happening, if this is the way it's supposed to work or if I should abort..
