Title: "South Tower Anomalies III -- Busted!"
This video demonstrates that ThoughtCrime7s video "South Tower Anomalies III Addressing the Debunkers" is disinformation. In the introduction to that video, the author claims the following: "This movie does NOT try to prove NPT (no-planes theory), only fake news." The video proves nothing of the sort.
Please look at the following references before commenting on anything.

Check out the shots of the North Tower roof area, in the helicopter shot: smoke can be seen swirling around on top of it, which is why it appears as though the static camera is higher than it is. There are many articles about lenses and photography on the Internet, but some of the terminology can apply to several related aspects of a subject. I have used the term "positional parallax" in relation to images of the same subject which have been taken by cameras in different positions.
The term "perspective distortion", in this case, relates to images recorded by cameras having long focal-length lenses, which have a narrow angle-of-view. Narrow-angle lenses tend to distort perspectives, which leads to a distortion of the size relationships of different objects in an image. For example: in a shot taken along a railway line, a long lens will make it appear as though the rails stay almost parallel to each other, as they recede into the distance, whereas a wide-angle lens will make it appear as though they rapidly converge to a point. Helicopter cameras, because they usually have to stay well away from their subjects, have zoom lenses whose long end can have an angle of view under 2º.
The importance of recognising the effect of perspective distortion, particularly when coupled to motion parallax, cannot be overstressed in relation to the many shots taken of the plane and the Twin Towers, on 9/11. A lack of understanding of these phenomena is the reason why so many people have fallen for Simon Shacks video about the Verrazano Narrows Bridge "moving" during some of the helicopter shots. It really is distressing to see that there are so many gullible people about.
There are several other errors, in ThoughtCrime7s video, which I have not bothered with, for example: the angle-of-view demonstration, at time-counter 05:53 which is concerned with why one of the cameras didnt capture the image of a helicopter in its frame while videoing the Towers. The error is that the "arms" of the angle-of-view graphic emanate from the subject, when they should, of course, be related to a camera.
