that is probably the 'Hemi tick' and you are probably fine. I say 'probably' because its only one video clip, you know your vehicle better than anyone else.
the 'Hemi tick' is pretty common, is not new and has been around as long as the Dodge/Chrysler Hemi engine has. here is an article on it.
The number one question we get from our customers with Hemi engines is, “is the Hemi tick bad?” Would you like to know? Read this blog.

"According to Chrysler/ Dodge, Hemi engines can develop a completely normal, harmless tick. In our experience, this can be true. We have checked out some Hemi engines with ticks in the past and have been unable to find any problems with them. Even better than that, the vehicle owners have not reported any issues developing after checking out the engines and reporting that they are fine."
my 2021 TNG with 2,400 miles does not have a tick. but my 2011 Durango CrewLux with 5.7L had the tick the whole time and I sold it with over 150,000 miles on the odometer.
