What you did (filming your screen) eliminates the possibility of a wall hack, but not an aimbot. To confirm there's no aimbot you would need to film your right hand. Then when people watch the video they can watch your hand movement (mouse movement) and make sure it is in sync with your cross hair movement. An aimbot will move your cross hairs for you, so it would be obvious if you're not doing it yourself. Filming your left hand is less important, but probably still necessary.
There's no kind of video editing that can fool the viewer. If there is I doubt any of us have the kind of money to pay for it.
Of course if you film an aweful game it proves nothing. I haven't been filiming games lately b/c of my work load (mucho overtime) - can't play too well. Not to mention my right mouse button keeps sticking - need a new one.
