So here is a video I shot (sorry for the poor quality, it was shot with my cell phone). It is dark, as it is getting dark outside and it was filmed under my carport, and the point of the video is the sound, not the image.
The car is fully warmed up in this video, so if I should take a video on a cold start I can. I do not hear anything that sounds like a knocking, ticking, or anything else (and definitely do not have the horrible sound as in the video in the OP) but I wanted to get some advice on here and see if anyone heard anything out of the ordinary, or if there is anything that might indicate that I could be looking at rod bearing issues (or any other issues you might hear)
Here is the conditions of the video:
