Filming a Cinematic

[Deep Sea Kraken]

I have absolutly NO idea what forum to post this; so im posting this here.

Ok i want to make a cinema and post it on a video web-site (like u-tube). Ive seen warcraft three videos there and i was wondering if anyone whould know how to do that. Do i need a special cord that will input the video data from my computer into a recording device OR is there a 3rd parety program to do it with? OR should i just take my camera and film the computer minoter as is plays?

Any help will be appreciated.
