Ufo video filming method

Just to explain to some that these objects shown on my June 19th 2004 video were not nats filmed over the grass as it should be noted that the camera was set on the tripod at around a 65-75 degree angle and zoomed out to 40x and the roof is over 20 feet away. Could some of the objects be bugs? Yes, but most are not. And the two objects which passed by in almost perfect focus were definatly not. Some times when you watch that video these two objects pass by so fast they can be missed. Watch it a few times ( frame by frame if possible) to see what I mean. This is at 2:30pm with the old guy in the next yard to the right hammering away on his new deck and my friend finishing his fresh rebuilt deck niether of them heard or saw a thing. It was like the Mexico footage only at high speed.
