Based on the last shot, could potentially be useful for diagnosing potential failures due to metal fatigue - the kind of vibrations that you may be able to hear, but can't see. Not sure if that's the intent, but that's what jumped out at me...

That's the intent; the video was shot by a vibration tester manufacturer (an awkward phrase). If you go to the URL at the end, it says that it's a promotion for a predictive maintenance tool that uses vibrations.
