It's a WBody...probably supposed to make those noises.
Kidding.
I can't see videos at work...

Kinda hard to tell with the video
My guess to start with, pull the belt off and see if there is any place in the supercharger coupler. Its known to go out after time and wear, easy fix, cheapest of all ticking problems. Pull the belt off, rock the SC pulley back and forth and see if there is any play in it, should be tight but if not, then start by replacing, there's write-ups galore if you search for coupler replacements. You could also roll the pulleys over and see if there are any harsh spots in the bearing when its rolling, this could make a similar sound.
If everything is fine, then well move on to making you
EDIT: you will hear "some" ticking, the stock injectors are kinda loud and you can hear them pulsing. At least on all the W-bodies I've seen you can. So some noise isn't bad, but that didn't sound like normal ticking

Buy a mechanics stethescope. It'll be the best $15 you've ever spent. Then isolate the sounds.
I can hear a cold air intake because the IAC is screaming loud.
Can hear either a loud injector, valvetrain noise or a bad pulley. Kinda tough from the angles you held the camera at.
Overall.. seems ok.

I do have an Open Cone Intake mounted on the throttle body, and I can take a longer video IF that will help better.
Bad pulley shouldnt be too much of a hassle to fix financially. How worried should I be if the noise is from the injector or valvetrain?

My car makes a similar noise and it is the main belt tensioner. I agree with the previous posters--first thing to do is pull the SC belt and see if the noise goes away. If it does, the problem is in the SC or the SC belt tensioner. Mine did not go away, so I went with step 2 which is the mechanics stethoscope previously mentioned. You can stick it on all the pulleys (or injectors, etc.) until you find the one that is making the noise. Mine happens to be the main belt tensioner, and it sounds similar to your noise. I think these are about $100, but I have not gotten around to fixing mine yet. It is not going to hurt anything if that is what it is.
BTW: I got my stethoscope years ago at Harbor Freight. They are on sale right now for like $4, and they are always sending out coupons for 20% off of any purchase: Mechanic's Stethoscope.

Well, as for the injectors you dont need to worry at all, they make a ticking noise under normal conditions, as stated above.
If it's a lifter tick, Seafoam is supposed to cure that.. I know it fixed a noisy valvetrain on my old Grand Am.

its a bad pully, take the belt off spin each pully untill you find the one that makes noise. replace it.. had the same **** on my car, ended up replacing idler and one other pully i forget witch.
