there isn't any explanation as to how the hole was created other than a guy jumped down the stairs (even then creating a perfectly rectangular hole is hardly even possible).
or why there are grey planks and a grey cube set over the hole
or who the guy taking the video is (though i might assume it's you)
or even what the purpose of the video is. i don't know what a tracking video is.
you might have to explain this a bit more.
