hi Guiseppe, in addition with David's explanations about interlaced videos, I would say that you should try to change the setting to 50 fps, there is a chance that it solves the problem. You can make tests on a fast target, for example a laser spot projected on a wall and quickly moved by hand. regards At 16:38 25/03/2011, Giuseppe N.
