There ARE some strange cuts there that don't match up time wise.
At 2:10, when he hits the playfield with a hammer, there is another hammer sitting on the table at the bottom left of the playfield, but during the "close-up" at 2:11, that hammer has vanished, only to re-appear at the second close-up at 2:13.
At 2:24, when the playfield is hit with the sledgehammer, that regular hammer is still there, but then at 2:31, during the close-up, the sledgehammer is sitting on the table to the left of the playfield (and the regular hammer has vanished).
The regular hammer then reappears at 2:43 again.
Now, I am NOT saying that they faked this or that they swapped playfields, or anything like that. I suspect that the close-ups were different "takes" than the shots from further back - with the hammer present for the back shots, and missing in the close-ups.
I don't see any "marks" that indicate they changed out playfields. There is a glare/reflection spot that could be mistaken for a mark, but if you watch the whole video, you can see that spot move around with the camera.
