Ya, that may or may not have something to do with it. It's a 4 cylinder engine, and if that's an "undamped" vacuum gauge, it might fluctuate like that and be normal. More cylinders = smoother reading (assuming the engine is ok otherwise), and a dampened vacuum gauge will smooth out the reading as well. I prefer undamped, but that's me...
Otherwise, that reading is kinda low.
Where are you at? Any idea what altitude?
What rpm is the engine running at in the video? Is the throttle closed? And by throttle, I don't mean the gas pedal, I mean the throttle plates themselves.
Engine warmed up or cold?
Do the same thing, but snap the throttle a few times, try to wind up the engine a bit.
