Dont know why you guys keep calling genlocks "video mixers" a video mixer and a genlock are 2 different devices. A Generator Lock just syncs the computer to the incoming video and allows for overlay, keying, or reverse overlay. A "video mixer" mixes more than 1 video source, sometimes with effects or transitions.
oh and the gvp g-loc is crap. The only good thing is audio mixing, multiple inputs, and software control. Other than that many other genlocks are better.. Supergen, Vidtech, Hama, etc
