Video editors...

Hello, people. As you may know, I have been making youtube videos for a while now. I am still really bad at making them, and most of them do not have cuts, and you have to wait while I try to make the camera focus on an object, or something else. For the few that I have made cut, I made them in windows movie maker. The only problem with this is that you can not shorten clips, and you can not cut them in half, and also, if you use the "snip" tool to make it cut, you can't put it in another video. I have tried to download a bunch of free ones, like avidemux, and Jahshaka, and Wax, and Video explosion (copyright 2002) but they all seem to be just like windows movie maker, or have virus on them, or are just advertisements. As you probably have gathered from Windows Movie Maker, I do not own a mac computer, so I can do not have iMovie. There is an iMac from 2006 that has some outdated OS.
