Wow, this is crazy. That infrasound makes my subwoofer move at a frequency that my camcorder sees as standing still. It's moving around quite a bit but the camcorder records it as if it were standing still half the time. The tower woofers' cone movement is much more visible to the camera though.
What's your camcorder's speed of pics per second? Assuming the usual cinema frequency, it's 25 shots per sec. So here you got, that's 25Hz that your camcorder can't 'see'.
EDIT: looked it up, it's called frames per second (FPS) and the minimum is 25Hz to produce a smooth sequence of pictures, and that increases monotonically with the price of the camcorder.
