I was googling about the best Linux movie editors,and found cinelerra, and also advice on how to get/install it. It looks like I have to first use this command: deb http://akirad.cinelerra.org akirad-intrepid main but I'm not sure how to do that, do I go in terminal and just type it in like that..in the root directory, or do I put 'sudo' before it or..and then what to do after that? I'm assuming it's an 'apt-get' kind of thing. thanks.
