That video was full of sounds and I couldn't tell which one is like your car. Generally vacuum leaks are more noticable at idle. I'd look closely at the intake tube piping around the air filter and down to the throttle body. Or anywhere else in the tube.
You might get a garage to run a smoke test on the car. They inject lightly pressurized smoke into the intake system with the motor off. Any intake leaks are easily identified. It cost me $75 to have it done on my car.
