How do I make my sony dsc w350 not blur while filming videogame playthroughs?

This also means just filming anything. My camera, when I am in video mode, I try to make good videos for youtube, but even before I put it on youtube, my camera would randomly start adjusting and blurring. I just want to have a steady video. I think there is something like an infinite zoom but I don't know how to use it. Can anyone tell me if you have this camera to try to get my settings to infinite zoom?and to make better game playthroughs. Thanks
