We had a storm a few months ago and before the storm a number of lightnings struck the area close to where I live. I recorder a video of the lightnings and I noticed something weird…

The first image shows the view from our house. The second and third images show two lightnings. The third image is quite interesting, because the closest building on that image is around 20 meters away from where I was standing; and the lightning trajectory appears all the way to the bottom of the picture. It’s been ages since I last studied physics, so even if I knew how to explain how this happened, I have now forgotten! My thoughts so far:

• either the lightning struck less than 20 meters away from where I was. It doesn’t seem likely, because I assume I would have felt it striking so close. Moreover the clouds where the lightning started its trip [sic] appear to be far away close to the mountains.
• or the camera was able to capture the trajectory of the lightning behind the trees and buildings!
• or…

…?
