At the end of the video, keep an eye on the glass door to the bottom left

The only thing giving it away is the time stamp in the top left corner. It pauses at the end.

Also, when it pauses, look closely at the man. You can see where he's moved slightly and they've unpaused the camera and continued filming (around 1.04).

I was quite WTF at first though!
