I have a laptop but it's too slow to run vue. Rendercow is a pile of crap that crashes on the first frame. I lost my serial code so I can't download the fix. I was rendering at 600x400 resolution at 72dpi. I cannot imagine why it is taking so long. But besides the point, do you know of any good film editing programs that have post production tools and use "green screeN'type alpha channeling?
