Firstly select the camera input( select once you see yourself .). Select current camera using 's' , change the camera using 'n' and 'p'.
Secondly, adjust the hue sliders till you only see your pointer and rest every other object disappears. Better the accuracy of this step, sharper will be the stroke rendering on the screen.
