Monooxide, that quite literally is hte entire point of posting a video(in the video section). Either that or to show off some good drifts. Either way those are the reasons people post videos. So feel free to post a vid.
But if you're getting snapping I can tell you right now it's a technique issue not a settings issue. In GT4 your inputs need to be smooth, precise and fluid. Unlike GT3 where you can be much more rough with the controls.
