Faza, I am no expert, but the first time, i just took a video, plugged the cord from my camera into the computer, the camera downloaded the software/video to my computer, i then jumped on youtube, clicked on browser, found the file i had saved, then downloaded it to youtube, then just listed the youtube link on AP.
I have a Kodac camera with video which makes like much easier. The new Cannon Video camera, I am yet to work out.
