Depending on what Du want to do if Du want to make a video of yourself and friends. All Du need is a video camera oder web cam. Editing software like Windows movie maker and a mic. Then after some editing just go to your Youtube account and upload. If Du want to do like i do just post Fan made Videos and amvs blablabla Du need clips,editing software,music and its ready to upload
Which it all depends on how complex Du want to make your videos. My first vid i ever gepostet was a slide Zeigen now i'm actually posting them with high quality video clips
there are several ways to get clips if Du want to go that wrought Du can get a dvd ripper and your set but there are other ideas too.
In general it depends on how much Du are prepared to spend
Well Du should go to google,then type Camstudio and then it will apear and it should Zeigen a website oder something but i went to Google and downloaded Windows Movie Maker.Whitch one,Camstudio,Windows Movie Maker,or both.
