'07 X5 4.8 loud knocking noise - video

Looking for some help on possible sources of this loud knock. Happens both when the car is hot and cold. Maybe started a month ago and was not as loud as it is now, but it has gotten more intense since I drove 450 miles on Friday. It becomes nore rapid as the rpm's increase. No check engine lights. My best guess for where its coming from is the pulley area.

Any educated opinions are very much appreciated.

Thanks in advance.
