The person in that video stated that you can clearly see WTC 7 leaning with the naked eye. Please provide evidence for that.
How about this.
This is a screen grab from about a minute prior before the collapse of the EPH, looking for the final amount of lean before collapse initiation.
Remember that NIST estimates collapse initiation started about 6 seconds prior to the start of the collapse of the EPH.
I rotated this screen grab to bring the longest, most defined vertical edge (the one marked "Ref Vertical") into a vertical position. Then I drew the red vertical line beside it (slightly offset so that you can see the parallelism).
That gave me a "true vertical".
I created a vertical line to the right of the western edge of WTC7. I also created the line parallel to the NW vertical corner of the building (slid slightly to the left of that edge in the image above.)
There is about a 2.5° tilt of the NW vertical corner of WTC7, prior to the internal collapses.
On the lower left of the image, I've transport vertical lines, parallel to the original, in order to verify that the "parallelism" holds true across the image, and is not the result of lens distortions.
The parallelism is very good.
Not perfect, but very good.
From image manipulation (looking for "best fits across all vertical lines"), I'd estimate the lean of WTC7 to be 2.5 ±0.2 at this time.
