I tried to video tape it, and you can clearly hear this unknown noise, however, it is clearer in person. Towards the end of the video, the sound goes away completely.


P.S. The car operates normally, NO codes on the dashboard whatsoever, everything seems perfectly normal while driving or idling.

Any toughts??? Here is the video:

My guess would be a bearing in the idler or tensioner. Or even one of the other bearings is highly possible.
I have had bearings that did that, noise and then nothing. If one finally seizes you'll need a new belt and a tow job.
Release the belt tension and spin the pulleys.
It's too dangerous to do the screwdriver to ear trick though.
